Main characters

Mega Man

DLN-001 Mega Man, known in Japan as  is the protagonist of the original Mega Man series. Originally created as a lab assistant named "Rock" by Dr. Light, he was modified for battle after Dr. Wily reprogrammed the original Robot Masters to take over the world. Due to his Variable Weapons System, he can copy the weapon of any Robot Master and use it as his own.

Dr. Light
Doctor Thomas Light, known in Japan as , is depicted as an aged scientist and roboticist. He is the creator of Mega Man and several other robots, and can be considered the father of Mega Man, Roll, and Proto Man. While a pacifist, he reluctantly recognizes that the use of force can be a necessity. He plays a supporting role, often developing and distributing new gear. In the Mega Man X series, set 100 years after the original series, Dr. Light resumes his supporting role through enhancement capsules that contain upgrades to X's systems together with messages relayed by silver/blue, slightly translucent holographic projections of the deceased scientist. He also appears in the "Navi Mode" of Mega Man and Mega Man 6 in the Mega Man Anniversary Collection to provide gameplay hints to Mega Man. Though Light died before the X series, his legacy continued through his last creation "X".

He is voiced by Antony Holland in Captain N: The Game Master, Jim Byrnes in the 90s TV series, Randall Wiebe in Mega Man X8, Mega Man Maverick Hunter X, and Mega Man Powered Up, Michael Mislove in Marvel vs. Capcom Infinite, Doug Stone in Mega Man 11, and Garry Chalk in Mega Man: Fully Charged.

Dr. Wily

 is a mad scientist and the main antagonist. He was originally a colleague of Dr. Light during their days as university students. Driven by jealousy towards Light and his achievements overshadowing his own, he reprogrammed Light's robots, with the exception of Rock and Roll, to assist him in taking over the world. He was however defeated by Rock, who upgraded to the combat robot "Mega Man". Wily returned as the antagonist in subsequent titles of the main series with a different scheme each time, only to be defeated and surrender to Mega Man at the end.

Wily has also been instrumental in the backgrounds of other characters in the series. He repaired the prototype for Mega Man, "Proto Man", and in Mega Man 7 used what he learned during the process to create his answer to Light's work, Bass. After Bass proved to be unreliable, Wily refined his design, creating the robot Zero. Zero would appear in the Mega Man X and Mega Man Zero games as a hero working alongside Light's last creation, "X". Though Wily died prior to the X series, his legacy continued through a virus initially carried by Zero and transferred to Sigma, creating the X series antagonist "Sigma Virus", along with all the Mavericks.

DLN-000 Proto Man, known as  in Japan, is an early prototype (and older brother) of Mega Man who made his first appearance in Mega Man 3, under the name of Break Man, to help train Mega Man by fighting him. Beyond their armor and personality, Proto Man and Mega Man are supposedly identical. However, at the end of Mega Man 2: The Power Fighters, it is revealed by Dr. Light that Proto Man's body has a fatal defect in its energy system, and as a result, is in great pain and has a more limited lifespan. He also appears in the "Navi Mode" of Mega Man 3 in the Mega Man Anniversary Collection to provide gameplay hints to Mega Man.

Bass
SWN-001 Bass,  in Japan, is a robot designed by Dr. Wily. He was constructed based on research conducted on Mega Man with the intention of matching his power, being a more advanced model of Robot Master when compared to Mega Man. Wily makes mention of discovering the energy that powers Bass, Bassnium, the most powerful form of energy on Earth, entirely by mistake. Despite being created by Wily and being more competent in his abilities, Bass frequently rebels against his creator when he feels Wily is standing between him and defeating Mega Man. He desires to defeat Mega Man and be acknowledged as the world's strongest robot. Though he wants to defeat Mega Man, Bass has worked together with him numerous times, though usually for his own purposes.

Bass's weapon is the powerful Bass Buster, which originally functioned similarly to the Mega Buster, albeit with slightly different shots.  As of Mega Man & Bass, however, the Bass Buster has lost its ability to charge its shots in favor of an increased rate of fire and ability to fire upwards and diagonally. Unlike the Mega Buster, the bullets do not travel through solid surfaces unless an upgrade is acquired and equipped. Like Mega Man and Proto Man, Bass can also copy the weapons of Robot Masters, his body changing colors to reflect the weapon currently equipped.  He can also combine with his robotic wolf  for the Treble Boost, allowing Bass to take flight and shoot more powerful projectiles from his buster.

Save for a cameo showing a schematic of Bass, Bass is absent in Mega Man 9. His absence was not explained, although according to the booklet that came with the Rockman 9 Arranged Album, Bass was undergoing some adjustments. He is playable in Mega Man 10, retaining his dash and rapid-fire, multi-directional arm cannon capabilities (though not his double jump), if additional downloadable content is purchased for the game. In the game's re-release as part of Mega Man Legacy Collection 2, Bass is instead unlocked by either completing the game or by using the secret code at the title screen of Mega Man 10.

In Mega Man 2: The Power Fighters, Zero makes a cameo appearance, and Wily says that it is a creation that will surpass even Bass itself. Bass says that he will destroy this creation, and that no other robot is more powerful than he is.

Roll
 is a female robot designed for housekeeping instead of fighting.  She is the younger "sister" of Mega Man, and plays a supporting role in the first game, and plays a more substantive role in subsequent sequels. Her name was never mentioned until Mega Man 3, marking her return, where her entry in Dr. Light's robot list is shown during the ending. She also appears in the "Navi Mode" of Mega Man 2 in the Mega Man Anniversary Collection to provide gameplay hints to Mega Man.

She is usually depicted in a red outfit with blonde hair in a ponytail. In Mega Man 8, she wears a new black and red dress with red boots and a green ribbon tying her ponytail up. While she was not designed for fighting, she is a combatant in the fighting games, Marvel vs. Capcom and Marvel vs. Capcom 2. She also appears as a playable character in Tatsunoko vs. Capcom: Ultimate All Stars, and Mega Man Powered Up. Alternate versions of Roll appear in two other Mega Man spinoff series: Roll Caskett in Mega Man Legends, and Roll.EXE in Mega Man Battle Network. Roll also appears in various other Mega Man media, including manga and the Mega Man cartoon.

Roll has proved popular amongst fans, who have created various Mega Man ROM hacks and fangames to place her in the main role as a female counterpart to Mega Man. Theresa Romano from The Mary Sue said Roll had been the sole female robot in the franchise's universe to have made a lasting impression on Mega Man fandom. She observed that Roll is notable for her constant character redesigns through the games or the animated series; for Romano, the most memorable iteration was the Ruby-Spears series version whose arm could transform into different household appliances. Joshua Scullin from University of Washington Tacoma saw Roll as a better female character than the ones featured from Nintendo Entertainment System games as she is not reward for the main character but instead a powerful character on her own. However, her weaponry was still called out for her distinctive weapon. In Gaming Disability: Disability Perspectives on Contemporary Video Games, Roll is seen as a clean up messes in a more common approach to women in the 1980s in contrast to the heroic exploits of her brother, Mega Man.

Rush
 is a robotic dog belonging to Mega Man. He is introduced in Mega Man 3, and has appeared in many games since.  Created by Dr. Light to be an all around support unit, Rush has the ability to transform into various forms. Rush Marine transforms Rush into a small, one-seated submarine, and Rush Jet transforms his legs into jet engines that let him take flight. Rush also has the Rush Coil, which is a spring that pops out of his back and helps Mega Man reach higher platforms that he normally can't access. Other games have him transform into a motorcycle and a drill car, and in the fourth and fifth Game Boy games as a spaceship. In later games, the Rush Adaptor allows Rush to attach himself to Mega Man, allowing him to float, shoot more powerful blasts, and launch his arms as projectiles.  In a couple of games including Mega Man 7 and Mega Man 8, Rush can be used to obtain helpful items, such as health.  Rush is seen as a Scooby-Doo like character in the Ruby Spears cartoon show. Popularly believed that the name of the character was another musical reference in homage of the band called Rush, but currently it is known that was inspired by another Capcom game named Rush & Crash. and the pronunciation of the name be similar to Lassie that is another dog character.

Supporting characters

Auto
Auto (Rightot in Japan) was created by Dr. Light as a lab assistant, due to Rock being unable to fulfill that role after his adoption of the superhero identity "Mega Man". He is introduced in Mega Man 7, where he provides Mega Man with upgrades and parts. However, despite his relatively late introduction, it is implied that Auto has been around for some time.  In Mega Man 8, Auto assists Mega Man in the Rush Jet scenes, using a rocket launcher as well as a propeller in his head that allows him to fly.  He also appears in Mega Man & Bass, creating upgrades for the player in exchange for 'bolts' dropped by defeated enemies. He returns again in Mega Man 11 as Dr. Light's lab assistant, and helps Mega Man by creating new parts for him from bolts collected from enemies. He also made a cameo appearance (or a robot of very similar appearance to him) in CD versions of Mega Man X3, watching TV in the background of the FMV intro for Volt Catfish's stage, making him the only robot from the classic series to also be seen in the X series.

Beat
Beat is a robotic bird that has appeared in many Mega Man games.  He was created by Dr. Cossack to provide additional support to Mega Man during the events of Mega Man 5.  Several of the games require the player to obtain a certain number of Beat Plates in order to use Beat.  Beat homes in on enemies, providing damage by slamming into them. He would perform the same function in Mega Man 6, however he would not attack bosses as he did in the previous game. In Mega Man 7, Mega Man 9, Mega Man 10 and Mega Man 11, he rescues Mega Man (and Proto Man in Mega Man 10) from pits. In Mega Man 8, he can assist Mega Man during the Rush Jet scenes. He also provides Mega Man with an energy barrier in Mega Man & Bass. He assists Duo and Proto Man as a temporary invincibility power-up in Power Fighters.

Dr. Cossack
Dr. Mikhail Sergeyevich Cossack was a Russian colleague of Dr. Light. He appeared in Mega Man 4 as the main antagonist; however, it turns out he was being blackmailed, as Wily had kidnapped his daughter Kalinka. When Kalinka was rescued by Proto Man and the truth was revealed, Dr. Cossack turned on Wily and becomes an ally to Mega Man. He is the inventor of Beat and the Super Mega Buster, as well as numerous industrial and military robots. He also appears in the "Navi Mode" of Mega Man 5 in the Mega Man Anniversary Collection to provide gameplay hints to Mega Man.

Duo
Duo is a robot hailing from outer space, designed to preserve peace and justice in the universe. Duo was formally introduced in Mega Man 8, battling a robot powered by Evil Energy. After crashing to Earth, he is repaired by Dr. Light, and soon becomes an ally of Mega Man.  After finally eradicating the Evil Energy on Earth, he thanks Mega Man and leaves Earth to resume his search.  He later appears in Mega Man 2: The Power Fighters, which was actually released before Mega Man 8 (but set after it), Mega Man Battle & Chase, and Rockman Strategy.

The bulk of Duo's offensive abilities are attributed to his powerful left arm, with a fist nearly as large as his own torso, and his large spiked body.  He attacks primarily by punching, though he is capable of using projectile weapons, the most powerful of which is a blast in the shape of his own hand.  He also appears to have the same weapon copying abilities displayed by Mega Man, Proto Man, and Bass. As with them, his body changes color in accordance with the weapon he has equipped.  Also, having been created for the purpose of destroying Evil Energy, he seems to have the unique ability to purge said energy from an infected victim's body, as demonstrated when saving Mega Man.

Eddie
Eddie, originally known as Flip Top in early Western manuals, was created by Dr. Light as a "walking suitcase", usually sent to help Mega Man by providing random recovery items during the game.  He is also able to fire bombs out of his head while assisting Mega Man in the Rush Jet sections of Mega Man 8.  Eddie first appeared in Mega Man 4.  Starting from Mega Man 7, Eddie only appears in the shop and no longer gives items to Mega Man.

Kalinka
Kalinka Cossack is Dr. Cossack's daughter, who was kidnapped by Proto Man (on Dr. Wily's orders) in order to force her father into unwillingly declaring war against Mega Man on Wily's behalf. She was however rescued by Proto Man right before Mega Man managed to defeat Cossack in his citadel. Kalinka is not present in any other games in the series, but appears in the "Navi Mode" of Mega Man 4 in the Mega Man Anniversary Collection to provide gameplay hints to Mega Man.

Kalinka is named after the famous Russian song of the same name.

King
King is a powerful robot appearing in Mega Man and Bass as the apparent main antagonist. Declaring himself the king of all robots, he seeks to wipe out humanity and establish a world populated only by robots. Mega Man and Bass had to battle him and many robots that had joined his army; when either one finally defeats King, it's revealed that he had actually been programmed to form a rebellion by Dr. Wily. While King seemingly dies after this revelation, during Mega Man's ending it is revealed that he survived and is now a wanderer, much like Proto Man. He then apologizes for his actions that he had caused and wishes to meet up with Mega Man peacefully.

King possesses an array of powerful weapons, including a shield that works a lot like Enker's, which is capable of absorbing almost any attack and firing it back in the form of a massive laser beam.  His other primary weapon is a massive battle-axe capable of slicing even Proto Man in half with one hit.  He also has the ability to merge with other vehicles to form King Jet Robo and King Tank Robo, the penultimate bosses of the game.

Tango
  is a green robotic cat and one of Mega Man's allies. Tango can roll himself into a buzzsaw and dive into enemies, until all in-area enemies are defeated, he falls into a pit or spikes, or his energy is expended. Tango only appears in Mega Man V for the Game Boy, Rockman & Forte Mirai kara no Chōsensha for the WonderSwan and makes a cameo on Mega Man 10 in the item shop when playing with Proto Man. Like many other characters, Tango's name is musical-themed.

Reggae
Reggae is a robotic bird who is the pet of Dr. Wily. He is featured in a drama CD featured only in Japan.  He was featured in Wily & Right no RockBoard: That's Paradise (or RockBoard for short) and Rockman & Forte: Challenger From the Future as a weapon for Bass.  His first cameo outside Japan is in Mega Man 7, where he appears if an invalid password is entered. He also appears as the shop keeper when playing as Bass in Mega Man 10.  Archie Comics' adaptation of Mega Man has him play a more prominent role, usually mocking Dr. Wily's various failures in the "Short Circuits" section.

Treble
 is Bass' equivalent to Mega Man's dog, Rush. Like Rush, Treble can assume a jet-like form and flym though he does so in the form of an armored suit known as the "Treble Boost". Created after Bass stole designs for the Super Adapter in Mega Man 7, it gives Bass limited flight capability and increased firepower. In Mega Man & Bass, the Treble Boost also grants Bass invulnerability while its energy lasts. The Treble Boost is also present in Mega Man 10, functioning similarly to its previous incarnation, but without the invulnerability. The name Treble clearly continues the music theme of the original Japanese character names, and Gospel likely refers to the musical genre of the same name.

Met
The Met (short for the Metall, Mettool, and Mettaur variants of the name), also known as "Hard Hat", is a flagship enemy of the series.  Appearing in nearly every game, the average Met is a tiny construction robot wearing a disproportionately-sized hard hat with a "plus" sign marked on it.  Mets usually wait below their helmet before attacking, as it is impervious to nearly all of Mega Man's weapons.  They appear in the various series of the Mega Man metaseries, with many different variations and forms, and very different from Sniper Joes, their look has practically not changed through the centuries in the lore of the metaseries (a Met from Mega Man ZX is identical to one from the original Mega Man series). In the original Mega Man, another common enemy character named the Picket Man, has a head similar to the Met, but with a full body, a shield, and a pickaxe. The Mets are a staple to the Mega Man series as the Goombas are to Super Mario Bros. The Mets appear in Super Smash Bros. for Nintendo 3DS and Wii U as a collectable trophy in both versions, as well as being enemies in the 3DS exclusive Smash Run mode.

Sniper Joe
Sniper Joe is a humanoid built by Dr. Light and later modified for infantry by Dr. Wily. They were based on Proto Man and are mass-produced for combat. Sniper Joes are a recurring enemy throughout the classic series, and many of the numerous variants often involve a Sniper Joe operating machines such as walkers, gun turrets, jet skis and helicopters. They have a head containing a full face black visor, resembling a motorcycle helmet with a single red eye.

Yellow Devil
The Yellow Devil is a powerful combat robot created by Dr. Wily. It is a giant robot with a body made from a shape-memory alloy, which it uses to split into multiple pieces and reform elsewhere. At the center of the body is a single, mechanical eye, which keeps the body together and is also its one and only weakness. The Yellow Devil is a recurring boss character throughout the series, with numerous successors and offshoots appearing in other games (such as the Yellow Devil MK-II in Mega Man 3, the Green Devil in Mega Man 8, and the Block Devil in Mega Man 10. Other Devil variants also appear in the various series of the Mega Man metaseries, including the Shadow Devil in Mega Man X5 and the Rainbow Devil in Mega Man Zero.

Early Western media referred to the Yellow Devil as the "Rock Monster", a change made due to Nintendo's policies regarding religious figures and names. However, the "Devil" name has since been used in more recent American releases. The Mega Man/Sonic the Hedgehog crossover produced by Archie Comics featured the Chaos Devil, a being combining the Yellow Devil concept with Chaos.

Mega Man Killers
The Mega Man Killers are a series of robots appearing in the Game Boy series.  The Mega Man Killers are robots created by Doctor Wily to destroy Mega Man, who in turn defeats each one of them and eventually foils Wily's most devious schemes.  All of them reappear as bosses in Game Boy version of Mega Man V, and all of them also reappear as bosses in the DLC stages from Mega Man 10. All of them are named after notable music genres.

Robot Masters
Robot Masters are a special kind of robot, mainly under the control of Dr. Wily, that possess a very advanced level of artificial intelligence. The system is jointly credited to Dr. Light and Dr. Wily, and most Robot Masters possess a unique identification code, consisting of a two-letter "series code" followed by one of N, No, or #, then a three-digit "serial number". They are generally humanoid in appearance, and they are often designed with specific purposes and human-like personalities and quirks. The list below is of the first six Robot Masters that were built by Dr. Light and reprogrammed by Dr. Wily, as well as two more that were added to Mega Man Powered Up so as to be consistent with other Mega Man games.

Mega Man 1 / Mega Man Powered Up Robot Masters
These Robot Masters were created by Dr. Light and were reprogrammed by Dr. Wily to serve him:

Mega Man 2 Robot Masters
These Robot Masters were the first line created solely by Dr. Wily to destroy Mega Man:

Mega Man 3 Robot Masters
Most of the Robot Masters listed here were created by Dr. Light and Dr. Wily at the time of their truce.

Mega Man 4 Robot Masters
These Robot Masters were created by Dr. Cossack, and remodelled into battle robots by Dr. Wily after he took Dr. Cossack's daughter Kalinka hostage.

Mega Man 5 Robot Masters
Dr. Wily created these Robot Masters in his next attempt to take over the world.

Mega Man 6 Robot Masters
These Robot Masters were created for the First Annual Robot Tournament and were reprogrammed by Dr. Wily in the alias of Mr. X.

Mega Man 7 Robot Masters
Four of the robots were created by Dr. Wily to activate and find him if he is not there to activate a certain code to keep them stasis. These robots activated during the time when Dr. Wily was in prison. After his escape, Dr. Wily obtained four more robots to serve him.

Mega Man 8 Robot Masters
Some of the Robot Masters were created by Dr. Wily while the others were stolen and repurposed by him.

Mega Man 9 Robot Masters
These Robot Masters were created by Dr. Light and were tricked by Dr. Wily into serving him who saved them from being scrapped after their period of use had expired.

Mega Man 10 Robot Masters
These following Robot Masters contracted Roboenza as Mega Man had to salvage parts of them to help Dr. Light find a cure for Roboenza.

Mega Man 11 Robot Masters
These Robot Masters have different manufacturers until they were captured during Dr. Light's maintenance on them and reprogrammed to serve Dr. Wily who also equipped them with his Double Gear System device. After Dr. Wily's plot is thwarted, Dr. Light and a Double Gear System-enhanced Auto recovered their bodies and worked to rebuild them and restore them to normal.

Mega Man & Bass Robot Masters
Besides Tengu Man and Astro Man, the following Robot Masters were used by King in his robot revolution. Some of them were created by King while others were modified by King.

Stardroids
The Stardroids (Space Rulers  in Japan) are a group of alien Robot Masters featured in Mega Man V. Hailing from an ancient alien civilization, Dr. Wily discovered them in some ruins and reactivated them as part of his plans to dominate the Earth. They are led by Terra (Earth  in Japan) and are made of materials that normal weapons cannot damage, forcing Dr. Light to create the Mega Arm to counter them. Among them, Dr. Wily also discovered a similar robot named Sunstar (Sungod  in Japan), who was created as a doomsday weapon. Sunstar is reactivated by Wily in a last effort to destroy Mega Man, but he turns on Wily before fighting Mega Man as the game's final boss.

Sunstar
| Sungod(サンゴッド, Sangoddo)
| Sunstar is the ancient robot Dr. Wily based his "Stardroid" designs on in Mega Man V.  He was apparently built by an ancient alien civilization in the solar system that is long gone by the time Wily discovered him. Upon being defeated, Mega Man helps bring him back to Dr. Light's lab and convince him that humans and robots can coexist peacefully, and while Sunstar would like to see that kind of world, he reveals that Mega Man has damaged his energy core and when he explodes, it'll take out the entire space fortress, and so Mega Man is forced to escape without him.

| SRN-001
Terra
| Earth(アース Āsu)
| Terra is the first Stardroid that Mega Man encounters and the "Megaman Killer" of Mega Man V. Terra defeats him easily, since his Mega Buster cannot damage him until Dr. Light upgrades him with the Mega Arm (which replaces his standard charge shot with a grabbing attack). After Mega Man defeats the 8 other Stardroids, he encounters Terra again, this time with the ability to destroy him. His name is based on Earth and the third planet of Solar System. His main attack is the Spark Chaser, a laser which can home in enemies and damage them multiple times. He can also teleport and fire a circle projectile that will freeze Mega Man. Terra's attitude towards Mega Man is not unlike that of Bass.

Mercury
| Mercury(マーキュリー, Mākyurī)
| Mercury is one of the first group of Stardroids. His name is based on the Roman messenger god of trade and the first planet of the solar system. His main attack is the Grab Buster (Snatch Buster in Japan), a projectile that can steal energy or power-ups from Mega Man and he can transform into liquid metal hopping in thrice and repeat the process. He can also steal power-ups and P-chips from careless players.

| Venus is in the first group of Stardroids. He is named after the Roman goddess of love and the second planet of the solar system. His main attack is the Bubble Bomb, a weapon that behaves similarly to Burst Man's Danger Wrap from Mega Man 7. If it is small, it travels in one direction until it explodes, however large bubbles remain stationary explosive traps. His design is based on a crab and similar to that of Toad Man from Mega Man 4.

His main attack is the Photon Missile, a powerful rocket that can tear through almost any enemy once up to speed. These are fired through a large launcher protruding from his head, similar to the rocket launcher Napalm Man from Mega Man 5 possesses. Also like Napalm Man, he is also equipped with autocannons for hands and shoulder-mounted missile batteries. Mars can also transform into a fully invulnerable tank and lay landmines while in this form. He is one of the more dangerous Stardroids.

Jupiter
| Jupiter(ジュピター Jupitā)
| Jupiter is in the second group of Stardroids. He is based on the Roman supreme deity and the fifth planet of the solar system. His main attack is the Electric Shock, a massive thunderbolt channeled through his body. When Mega Man acquires it, the weapon functions like a tazer. He can also fire electric sparks from his arms. Jupiter was originally designed with a high-yield electron bomb in his arsenal, however his fear of explosives led him to avoid using it. According to his CD data in Mega Man & Bass, he has a rivalry with Gyro Man, supported by his quote ("Clear my way, propeller scum!").

| Uranus(ウラノス Uranosu)
| Uranus is in the second group of Stardroids and the strongest of the group. His name is based on the Greek mythological god of the skies, ancestor of gods, and the seventh planet of the solar system. His main attack is the Deep Digger, which functions similarly to Guts Man's Super Arm from the original Mega Man in that it requires external ammunition in the form of special blocks to use. Uranus is so heavy he can cause massive cave-ins simply by jumping repeatedly. His defense is so incredibly tough that even a fully charged Mega Arm can deal only minimal damage.

Mega Man X characters

The following is a list of recurring characters appearing in the Mega Man X series of video games developed and published by Capcom. Unless otherwise stated, each of these characters is a reploid; an artificially intelligent android. Names are organized in order of appearance, and characters who only appear in a single game are covered in the article for the corresponding game.

Maverick Hunters
The Maverick Hunters (Irregular Hunters  in Japan) are a group of Reploids who protect humans and other Reploids from Mavericks and the heroes of the Mega Man X series, and the protagonists of each game are prominent Maverick Hunters. When they are introduced in Mega Man X, they have already existed for quite a while, having been previously founded by Dr. Cain (who has since retired). From Mega Man X on, they battle Sigma and the other Mavericks.

X

X is the lead character of the Mega Man X series. He is originally created by Dr. Light, who feared the ramifications of giving robots free will, so he chose to seal X inside a capsule for 30 years to test the integrity and reliability of X's systems. Dr. Light died before X's diagnostics were complete, and X was discovered in his capsule 100 years later by another scientist, Dr. Cain, who attempted to emulate X's technology. With X's help, Cain developed the first mass-produced Reploids: humanoid androids based upon X's designs.

Zero

Originally intended to be the protagonist of Mega Man X, he was recast as the mentor and, later, partner of X in favor of an X who looked "more like Mega Man". He is a top class Maverick Hunter who undergoes constant inner turmoil regarding his mysterious past and purpose, of which he seems to see glimpses of in nightmares, and the fact that the Virus does not affect him like it does other reploids, who have their programs corrupted and turn erratic and violent and bent on human destruction, becoming "Maverick".

Axl
Voiced by (English): Lenne Hardt (X7); Jeffrey Watson (X8)Voiced by (Japanese): Minami Takayama
, a black and red-armored reploid with an X-shaped scar above his nose. With the attributes of a child in X7, he is a fairly recent introduction. Having first appeared in Mega Man X7, he displays the unusual ability known as A-Trans which allows him to take on the appearance and abilities of any reploid he defeats which matches his size; an ability that is initially unique that allows him to explore normally inaccessible areas. Axl is also armed with a pair of handheld blaster pistols, which he calls Axl Bullets, and the ability to hover in midair and roll through enemy shots. While his gameplay style was originally similar to X, in Mega Man X8, Axl's gameplay had been reworked to create his own distinctive fighting style. His shots now have intense rapid-fire abilities and can fire in any direction, (similar to Bass from the classic Mega Man series) and instead of copying the same Maverick weapons like X can, Axl instead gains a new type of gun for each boss he defeats which has unlimited ammo (unlike X7 where Axl could only receive three new guns which he switches to when he uses the Maverick weapons that come with them). These special guns can be fired in the same way as Axl's regular attacks (multi-directional and rapid-fire). While overall the weakest in power, Axl's fighting style relies more on speed compared to X's powerful but slower charge shots and Zero's swordplay.

Dr. Cain
Voiced by (English): Michael ShepherdVoiced by (Japanese): Tadashi Miyazawa
Dr. Cain, a human archaeologist-turned-robot expert, serves a vital, yet shrinking role in the Mega Man X games and their backstories. In the story of Mega Man X (told in the form of Dr. Cain's journals), Dr. Cain discovers the dormant X in the ruins of Dr. Light's lab. After awakening X, Cain invents Reploids, sapient robots based on X's design, with the most notable being Sigma. Sigma, being the most advanced robot at the time, was placed as the head of the Maverick Hunters (Irregular Hunters in the Japanese version), a group of reploids dedicated to destroying any reploid that violated the three rules of robotics.

Iris
Voiced by (Japanese): Yūko Mizutani
Iris was developed by Repliforce scientists as half of the "Perfect Soldier program". Colonel, her brother, was the other half. Her half was of the compassionate and peaceful one, and Colonel's was of the strong-willed Reploid warrior. Repliforce scientists had struggled to make these two factors into one Reploid, but the differences were irreconcilable, so they split them into brother and sister Reploids.

In Megaman X4, Iris is one of the two characters alongside Double who can only be fought depending on whether the player chooses Zero or X respectively.

Alia
Voiced by (English): Rumiko Varnes (X7); Marriete Sluyter (X8)Voiced by (Japanese): Rumi KasaharaAlia is a character in the Mega Man X series. She acts as a Navigator for the Maverick Hunters in Mega Man X5 and onwards.

Alia began her career as a simple researcher in Reploid engineering. She and her colleague Gate whom she was said to have feelings for, were ahead of their time in their research on Reploids, though she contends that Gate was always a better programmer than she was. However, Gate's inability to follow the rules made him a social outcast, and his creations were systematically destroyed, sometimes even with the assistance of Alia herself. She soon mastered all programming languages and was chosen on these merits to be a spotter for the Hunters. In Mega Man X5, Alia then served as the Hunters' spotter (navigator) during the Sigma Virus outbreak, while simultaneously lending her technical talents to the cause by uploading and letting X utilize his two new armors, the Falcon and Gaea armor. She supported the Hunters throughout the ordeal until it was resolved. And most of the time, she worries for her comrades.

Layer
Voiced by (English): Meredith Taylor ParryVoiced by (Japanese): Sonoko Kawata
Layer is a navigator alongside Alia and Pallette in X8. She appears as a tanned reploid with long violet hair set in a hime cut. Her high processing power allows her to quickly determine enemy abilities. For the most part, Layer appears to be the oldest navigator, staying calm and collected. However, she seems to show more concern for Zero, even blushing when talking to him. Palette's comment on how she "waited the whole time for him" seems to imply that she has a crush on him. Layer is also a secret unlockable character in the game, and has gameplay similar to Zero's. She has her own sword weapon, the "Layer Rapier", allowing her to use the same abilities as Zero, but she cannot use his "Black Armor".

Pallette
Voiced by (English): Chris SimmsVoiced by (Japanese): Haruna Mima
Pallette is another navigator alongside Alia and Layer in X8, appearing as a reploid with blonde hair and turquoise armor. She excels at finding hidden routes at facilities, often allowing X to find Dr. Light's armor capsules. She appears to be the most playful of the navigators, and hates being ignored. Pallette is also an unlockable character in the game, taking after Axl's playstyle. She cannot, however, use Axl's copy ability.

DouglasDouglas is a mechanic for the Maverick Hunters. In Mega Man X5, he constructed power-up parts (or "modules") for X and Zero and reinforced the Enigma Cannon and Space Shuttle with the parts they gathered from the Mavericks. During the Nightmare outbreak (X6), Douglas helped X and Zero by refining power-up parts for them. Although he is still employed by the Maverick Hunters, he has not appeared in-game for a while. He is a somewhat eccentric character who prefers to look on the lighter side of things. He can fix about anything.

Signas
Voiced by (English): Robert Belgrade (X7); Roger Rhodes (X8)Voiced by (Japanese): Hirotaka Suzuoki (X7); Tsuneyoshi Iwatsuru (X8)Signas is the newest leader and commander of the Maverick Hunters, introduced in X5. He was originally a private investigator before being assigned to the Maverick Hunters. Signas commands every mission executed by the Hunters, and he often plans out major operations, overseeing them carefully. Very loyal to humans and Reploids, Signas will stop at nothing to ensure that all Mavericks are eliminated, as he has already proven to be a worthy leader and valuable Hunter. He has the most advanced CPU of all current Reploids and is somewhat similar to Colonel from X4 in appearance.

MavericksMaverick ( in Japan) refers to Reploids who turned against humanity due to the effects of the Maverick Virus or of their own accord, depending on the individual.

The Mavericks also appeared as the main villains in the Worlds Unite crossover from Archie Comics, which took place between the Sonic the Hedgehog, Sonic Universe, Mega Man, and Sonic Boom comic lines. Following the events of X7, Sigma traveled back in time to Sonic the Hedgehog's home world, and later cloned the vast majority of the Mavericks featured in the series. The only exceptions are those featured in Command Mission and a handful from the other games.

Sigma

 is the primary antagonist of the Mega Man X series, considered to be the finest reploid by Dr. Willie of the time with circuitry designs meant to keep him from going Maverick . He was once the leader of the Maverick Hunters, but during a mission, he came into contact with Zero, who at the time was under the influence of the Zero Virus and had been running berserk.

Vile
Voiced by (English): Roger RhodesVoiced by (Japanese): MugihitoVile ( in Japanese) is a recurring major villain in the Mega Man X series, and frequently reappears as a mid-game boss. He has a distinctive helmet with a T-shaped visor, similar to that of Boba Fett. Vile is introduced in Mega Man X, where he is a former Maverick Hunter now serving Sigma as his right-hand man.

X-Hunters
The X-Hunters, known as the  in Japan, are a group of three Mavericks who are formed to counter the Maverick Hunters and tasked to destroy X, and are the main antagonists of Mega Man X2. The members of the group are , the muscle and enforcer, Serges ( in Japan), the brains and scientist, and , the speed and military strategist. They are among the few remaining followers in the Maverick rebellion and led a rebellion of their own after Sigma's death and took over the North Pole. They were also in possession of Zero's parts, which was part of their Unification Plan to rebuilt Zero as a Maverick, and they challenge X in a dual for the parts after some of their Mavericks were defeated. Each member is found in a secret area of a stage and will move to another stage. After X beat each of the X Hunters, he recovered all three parts and has a final battle with them at their lair. One by one, all of the X Hunters were destroyed and eventually X confronts a newly revived Sigma.

Dr. Doppler
 is the main antagonist of Mega Man X3. Dr. Doppler is depicted as a Reploid researcher who supposedly discovered a cure for Maverick Reploids, and even founded a city, Dopple Town, in honor of it. When the supposedly cured reploids began causing riots in Dopple Town, the Maverick Hunters held Doppler accountable. After X and Zero defeats him, Doppler reveals that he was corrupted by the viral form of Sigma, who ordered him to create a new body for him. Eventually, Zero would learn that Dr. Doppler has the true antivirus, and applies it to his Z-Saber to finish off Sigma and get X and himself out of Doppler's exploding laboratory. (Alternatively, if Zero is injured, Dr. Doppler uses his own body as the true antivirus and sacrifices himself.) Dr. Cain was his friend.

Nightmare Police
The  is duo of Reploids who were the law enforcement in Dopple Town formed by Dr. Doppler to protect it before the uprising and joining his army, consisting of Bit ( in Japan), the faster of the two, and Byte ( in Japan), the stronger of the two. Doppler sent them to destroy X and Zero. They are found and fought in any of the eight stages in Mega Man X3. If at least one of them is defeated but not destroyed, they combine to form  in the first stage of Doppler's fortress, which is an upgrade from Doppler after their first defeat.

Double
 is a supporting character in Mega Man X4. He quickly befriended X during his mission and acted as his mission operator, but as X headed off to the Final Weapon, Double revealed his true purpose: he was a spy sent by Sigma to infiltrate the Maverick Hunters, unveiling his true personality as a combat-loving sadist, cruelly taunting X about his naivety when he was defeated. After slaughtering some Maverick Hunters in their headquarters, Double went after X inside the Final Weapon, and revealed his true form to him, causing a disbelieving X to realize he was betrayed, and confronted him in combat. However, X managed to destroy him.

Dynamo
, introduced in Mega Man X5 and later recurring in Mega Man X6 as an optional boss, is a Reploid mercenary who works for Sigma.

Gate
 is the main antagonist of Mega Man X6 and a researcher who formerly worked with Alia. Bearing knowledge far ahead of his peers, Gate ended up being exiled from the research community when his colleagues, including Alia, conspired to destroy Gate's Reploids out of fear for their power and inability to be analyzed. Months later following the crash of Eurasia, Gate discovered a piece of Zero's DNA and became infected by traces of the Maverick virus within it. Obsessed with building his own utopia for only the most supreme Reploids, Gate created the Nightmare Virus and the Zero Nightmare (a distorted and deranged clone of Zero) to instill fear in the population, then revived his Reploids as the "Nightmare Investigators" that would supposedly protect them but in reality lead them to their deaths.

IsocIsoc is Gate's chief assistant in Mega Man X6. He is first seen giving a rousing speech to the Reploids and recruiting them as Nightmare Investigators. His actual goal, however, is to observe the effects of the Nightmare Virus and report them to Gate for further refinements. Isoc also shows an obsession with Zero, claiming that he knows everything there is to know about him.

High MaxHigh Max, known as  in Japan, is an antagonist in Mega Man X6. He was created by Gate as the ultimate Reploid, using DNA taken from Zero to make him incredibly powerful and resistant to damage (though this resistance can be overwhelmed with enough force). As the leader of the Nightmare Investigators, High Max is assigned the task to seek and destroy the Zero Nightmare as part of Gate's farce to lead the "low-grade" Reploids to their deaths through blind trust.

Red
Voiced by (English): Barry GjerdeVoiced by (Japanese): Akio ŌtsukaRed appears in Mega Man X7 as the main antagonist and the leader of Red Alert, an anti-Maverick mercenary group that had risen to prominence in place of the overworked and underequipped Maverick Hunters. He was the one who adopted and trained Axl, who looked up to Red as a father figure. After Red met with a mysterious "Professor" (Sigma) who claimed that he could increase his power, he began acting unusual and Axl took it as a sign to flee for his life, ultimately seeking asylum with the Maverick Hunters.

Lumine
Voiced by (English): Elinor HoltVoiced by (Japanese): Junko NodaLumine is the main antagonist of Mega Man X8. Due to being a new generation Reploid, he can transform into other Reploids. Lumine is introduced as the director of the Jakob project, the Orbital elevator in the beginning of X8. He was soon kidnapped by Vile, due to his knowledge of the elevator. After defeating Sigma (originally thought to be the instigator of the events of the game once more) on normal or hard mode, Lumine is revealed to have been manipulating a weakened Sigma this time around, though he really means that he is essentially Sigma himself, and is carrying out his plans. He knows that Sigma could not do what he did in the whole series forever. He goes onto claim that this was Sigma's final death and that would be unable to return.

Mega Man Battle Network characters
The following is a list of characters from both the Mega Man Battle Network series of video games, and the MegaMan NT Warrior (Rockman EXE) anime and manga.

Protagonists

Lan Hikari

, is a fifth-grade student with a strong bond with his NetNavi, MegaMan. He is the son of Yuichiro Hikari and Haruka Hikari, and the grandson of Tadashi Hikari. He had a twin brother, Hub Hikari, who died when they were young, and it is later revealed that MegaMan.EXE is actually Hub reincarnated as data. MegaMan.EXE has a .1% modified difference in his DNA to avoid a connection between the two, but it is eventually erased, which causes them to become synchronized.

He is voiced by both Alex Doduk and Brad Swaile in the English version of the anime, Mark Gatha in the English version of Mega Man Battle Network 5: Double Team DS and Kumiko Higa in Japanese.

Lan is a typical carefree, happy-go-lucky youth in search of adventure and fun. However, he is quick at noticing the smallest details thus enabling him to think calmly during a sticky situation. Lan is also known as to be dense when things aren't Net related. He frequently NetBattles, and places the prospect of completing menial tasks like homework behind him. Despite his seemingly carefree attitude, Lan is always prompt to do the right thing, either for the world, or simply for a friend. He is talented on inline skates in every version of the franchise and commonly decorates his room with soccer-themes. Lan can be quite rash at times, but his actions sometimes have a positive effect.

MegaMan.EXE
 (Mega Man) is the main NetNavi protagonist of the series. He is very close to his operator, Lan, and it is later revealed that he is actually , Lan's twin brother reincarnated as data.

Mega Man Battle Network 6's post-credits scene revealed that Lan and Mayl eventually married and have a child together named "Patch" ("Raito"). The two have always been very close growing up. Mayl, being the more mature and intelligent of the two, is often having to beat some sense into Lan when he gets himself into trouble. The two do occasionally have oppositions, but the bickering only brings them closer. Mayl sometimes shows that she may have romantic feelings towards her lifetime friend. Roll and Megaman's relation strongly parallels that of Lan and Mayl's, though Roll is much more blatant with her affection towards Megaman. She was renamed Maylu Sakurai in the English anime and manga. It is revealed in the 5th game, when the character observes Mayl's house in a Visionburst 11 years in the past, that Mayl's father is Netopian making her at least half Netopian.

She is voiced by Brittney Wilson in the English anime and by Kaori Mizuhashi in the Japanese anime.

His mother died while he was still young, and Chaud was forced into becoming the vice-president of his father's corporation, a position which contributed to his initial cold attitude towards Lan Hikari. As the series progresses, he gains more respect for Lan, and also begins to open up to others, smiling more often. He does not, however, lose his serious outlook during battle, nor does he act impulsively before thinking. In the English anime and manga, his surname was changed to Blaze and Chaud was made his first name instead, giving him the new name of Chaud Blaze.

Nebula
DarkChip Syndicate Nebula is the antagonist group of Mega Man Battle Network 4 and Mega Man Battle Network 5. It is unique in that, aside from Dr. Regal (and Ms. Yuri in the anime), no named human operators are shown to be involved with the group.

Dr. Regal
 is the human mastermind behind Nebula, and the operator of LaserMan. He is Dr. Wily's son and comes from the small, authoritarian country known as Nation Z.

He is introduced in Battle Network 4, as one of the scientists working together to prevent Duo's asteroid from striking the planet. However, near the end of the game, he reveals that he is behind the spread of "Dark Chips." He sends LaserMan into the asteroid, but MegaMan pursues the Navi. LaserMan is deleted in the resulting battle, and MegaMan manages to avert the crisis. Dr. Regal leaps from the top of the NAXA building to avoid arrest, and is presumed dead.

In Battle Network 5, he kidnaps Dr. Hikari and uses Nebula to take over the entirety of Cyberworld. As Team ProtoMan or Team Colonel slowly take back the internet, Regal prepares to activate the SoulNet system. Using SoulNet, which was developed by Tadashi Hikari and Dr. Wily to connect human emotions, and Nebula Grey, a monstrous program that is the embodiment of evil, he plans to forever corrupt the population. However, he is thwarted by MegaMan, who destroys Nebula Grey and the DarkChips. After the battle, Regal has a decade of his memory erased; the Team Colonel version of the game reveals that it was Dr. Wily that caused this amnesia. He is seen working at SciLab at the end of the game.

In the anime, Dr. Regal is the top energy scientist of Kingland. In the past, he was rescued from a plane crash by Duo, who selected him as a probe to monitor life on Earth, and adopted by Wily. In Axess, he visits Dr. Hikari to look over a commandeered Dimensional Converter used by the Darkloids to substantiate in the real world, but is eventually recognized as the leader of Nebula. He, along with Ms. Yuri, collaborate with the Darkloids to wreak havok on Cyberworld. When ShadeMan, leader of the Darkloids, becomes suspicious of the humans, he is assaulted by LaserMan and is forced to flee. Dr. Regal later uses Regal Tower to create a worldwide Dimensional Area. After deleting ShadeMan once and for all, the now-Cross Fused Dr. Regal moves to destroy SciLab. He is thwarted by Lan and MegaMan, who use "Full Synchro" to badly damage him.

Dr. Regal is voiced by Kazuhiro Nakata in Japanese, and Trevor Devall in the English dub.

In Rockman EXE: Program of Light and Dark, it is revealed that Regal has become badly fragmented data. He fuses with Nebula Grey (a program created by Dr. Wily) and attempts to use the "Spectrum" phenomenon to gain access to, and eventually destroy, the real world. After being defeated by MegaMan and Bass, he reappears in Stream, using the Crests of Duo to obtain great power. However, he is destroyed once and for all by Duo himself.

Dr. Regal first appears in volume 10 of the Mega Man NT Warrior manga as the weapon development director for the country, Netopia. Later on it is discovered that Dr. Regal is behind the Darkloids in the Netopia Net Army and that he wants MegaMan's ability to merge with Bass, so that Nebula Grey can become even more powerful. However, using Beast Out, MegaMan destroys Nebula Grey. Bass then destroys Dr. Regal's submarine, killing him.

Darkloids
The Darkloids are a group of solo Navis that are addicted to DarkChips. They are Nebula operatives in the games, while they are an independent group that collaborates with the organization in the anime.
 ShadeMan.EXE – A vampire bat-themed Navi that appears in Battle Network 4 and Battle Network 5. Near the beginning of Battle Network 4, he kidnaps Roll with the intent of devouring her energy. MegaMan attempts to battle him, but cannot hit him due to his "Dark Power." ShadeMan leaves, but not before dropping a DarkChip. This DarkChip is later used by MegaMan to defeat Shademan. In an optional side quest, Solar Boy Django and MegaMan use the PileDriver in an attempt to delete the Navi once and for all. He returns in Battle Network 5 as one of the Darkloids that have taken over Cyberworld; he controls Oran Island's network. In the anime, he is the leader of the Darkloids. After discovering that the DarkChips will eventually delete any Navi that uses them, ShadeMan attempts in vain to kill Regal. LaserMan takes ShadeMan's position as the leader of the Darkloids, and ShadeMan is later deleted by a Cross Fused Dr. Regal. ShadeMan.EXE is voiced by Hidetoshi Nakamura in the Japanese version and by Scott McNeil in the English dub.
 LaserMan.EXE – Dr. Regal's personal Navi. He attempts to control Duo's comet in Battle Network 4, and Cross Fuses with Regal during the climax of Axess so that they can destroy SciLab. LaserMan.EXE is voiced by Kazuhiro Nakata in the Japanese version and by Michael Kopsa in the English dub.

Duo.EXE
 is a mysterious being from outer space. In both Mega Man Battle Network 4 and Rockman EXE Stream, Duo seeks to "cleanse" Earth of evil.

In the games, Duo is the operating system of an asteroid poised to destroy Earth. He was attracted to the planet by the spread of Dark Chips that was instigated by Nebula. After Dr. Regal sabotages NAXA's attempts to divert the asteroid, he sends LaserMan in an attempt to control it; however, LaserMan is deleted by MegaMan. Duo then appears before MegaMan and, after forcing the Navi to fight his own dark soul, engages him in battle. MegaMan manages to destroy Duo's battle body and, using the energy of humans worldwide, successfully changes the asteroid's course. Before MegaMan leaves, Duo warns that he will return again someday.

In the anime, he is a god-like entity created by an alien race. Fifteen years prior to Stream, Duo visits Earth and rescues Dr. Regal and Ms. Yuri from a plane crash, turning them into probes. He returns after having seen the violence brought on by Regal, but decides to spare humankind if it proves its worth. He is voiced by Kenji Nomura.

Duo possesses a variety of extremely potent abilities, many of them manifesting themselves in the form of space-age weaponry. His fists can detach and fire through rocket propulsion to strike his enemies. His chest cavity houses explosive artillery, which is launched in either a direct or homing fashion, as either mines or missiles. This cavity may also compress in on itself to release a powerful focused laser beam that fans out at certain points along the spectrum. His most devastating technique is Anger Impact, where he releases a wave of energy that resembles his face. In the anime, Duo also possesses the ability to separate Navis and operators from Cross Fusion with a mere thought, allowing them to take on physical bodies while in his asteroid.

Cybeasts
The Cybeasts are the titular cyber beasts from Mega Man Battle Network 6: Cybeast Gregar/Cybeast Falzar. They were originally created by the grandfather of Mayor Cain. Lord Wily seeks to obtain the legendary beasts so that he may wreak havoc on both Cyberworld and the real world. Their exact roles in the story depend on the game version: the title Cybeast is absorbed by MegaMan.EXE and is later destroyed by him, while the opposite Cybeast is absorbed by CircusMan.EXE and is ultimately deleted by Colonel and Iris.

In the anime, Gregar and Falzar each lead an army of Zoanoroids.

Cybeast Gregar
Cybeast Gregar known as  in Japan, is a legendary wolf-like sentient program created from accumulated bugs, much like the Gospel Megavirus.

In the anime, he is the leader of the Gregar Army which consists of Zoanoroid versions of BlizzardMan.EXE, DarkMan.EXE, FlameMan.EXE, GutsMan.EXE, JunkMan.EXE, MetalMan.EXE, NapalmMan.EXE, NumberMan.EXE, PharaohMan.EXE, PlantMan.EXE, QuickMan.EXE, Sparkman.EXE, StoneMan.EXE, WhaleMan.EXE, and YamatoMan.EXE.

Cybeast Falzar
Cybeast Falzar known as  in Japan, is a legendary falcon-like sentient program created by Dr. Cain, Mayor Cain's Grandfather, to combat Gregar; the program would go awry, eventually becoming as much of a threat to Cyberworld as its original enemy.

In the anime, he is the leader of the Falzar Army which consists of Zoanoroid versions of CloudMan.EXE, FreezeMan.EXE, GateMan.EXE, KendoMan.EXE, LarkMan.EXE, Meddy.EXE, Punk.EXE, SnakeMan.EXE, SwordMan.EXE, and the CutMan.EXE Brothers. Zoanoroid SparkMan.EXE used to be part Falzar's army until he was converted to Gregar's army by Zoanoroid PharaohMan.EXE.

Bass.EXE
Bass, known as  in Japan, was intended to be the first fully autonomous NetNavi, fully independent of an operator, and extremely powerful. Bass was falsely blamed for causing massive problems in the original internet, and was nearly killed by the SciLab Elite Corps. Dr. Cossack, the only human he trusted and his creator, was arrested before he could plug out Bass to safety, leading Bass to believe that he had betrayed him as well and hates humanity since then.

In Battle Network 2, Sean Obihiro of Gospel attempted to make a clone army of Bass copies, eventually leading to the accidental creation of the Gospel Megavirus. During the game's ending, Bass is shown deleting one such clone and swearing revenge upon mankind. Bass returns to fulfill his promise in Battle Network 3, where he assists Wily in using Alpha to destroy network society; however, Bass is swallowed up by Alpha along with Wily himself. He is then approached by the remains of the Gospel Megavirus, which saves him and fuses with him. He is later confronted by MegaMan in the secret area, and narrowly defeated. It is revealed that he suffers from amnesia, but Megaman is successful to remind him of his creator, Cossack. Thrown into confusion, Bass leaves.

In Battle Network 4, Bass is found deep in the Undernet hibernating as a statue, and reawakens upon meeting Megaman. Once again defeated, he retreats and vows to become stronger. In Battle Network 5, a post-game boss created by dark power takes on his likeness, but his true self can also be fought. Whenever defeated, he leaves of his own volition; this trend continues until Battle Network 6. There, Bass is confronted in his gravestone in the Undernet and numerous times afterwards. The final confrontation with Bass is his most powerful, when he has absorbed a cybeast's power into his body. When defeated, he drifts away into the net and is available as a random encounter in the Graveyard area.

In the anime, Bass was created from PharaohMan's data by Wily. Bass came to exist from the left over data of PharaohMan that Wily didn't use to make Gospel. While Gospel contains PharaohMan's ultimate program, Bass on the other hand is the reincarnation of PharaohMan's soul but lacking any memories, which were used in making Gospel, though he later recovered his memories after reading Megaman's memories. Bass is voiced by Matt Hill in the English dub.

In the manga, Bass' background stays true like the original but with a more violent personality. He is infamously known as the 'Black Shadow', the strongest Net Navi in the Undernet. Also, compared to the anime and the game, Bass is portrayed having deeper rivalry, and to an extent a friendship with MegaMan.
