Power Instinct, released in Japan as , is a fighting video game series created by Atlus. The series is known for its absurdist humor. Unique to the series was the introduction of the transformation feature: several of the characters can change their appearance and fighting style by simply executing certain moves (usually a throwing move), though this has not been featured in every entry in the series. Other features include the ability for every character to perform a double jump, run, and attack while running. Games Power Instinct Released in Japan as , the first game of the series was released in 1993. In it, players play as a member of the Gōketsuji clan, who are battling to determine who will replace 78-year-old Oume Gōketsuji as head of the clan. It has eight selectable characters and one unplayable boss character, Oume Gōketsuji, a palette-swap of her younger sister Otane. Originally, every character had a specific win quote for each defeated foe, but that was reduced to only one win quote for each character in the English version. This game was ported to the Super NES and the Sega Mega Drive. The Super NES version includes some new play modes: Vs. Battle, Practice Mode, Time Attack and a "Life Attack" that consists of defeating as many opponents as possible with just one life bar (similar to the Survival Modes seen in other fighting games). The Mega Drive version, which was never released outside of Japan, has a Battle Royal mode where 1 or 2 players can select a team, with an option to hide the characters being chosen so they are not revealed until the fight. Additionally, it features an option that allows the strength of each special attack of every playable character to be adjusted to the player's liking. The English console version of this game, which was only released in North America, had several omitted features, such as Karaoke Mode with the lyrics for the songs "Tatanka no Uta" and "Otoko no Karatemichi", character biographies that pop up in between demos, the intro demo to the game and the scene of Oume where she speaks to the player before she fights them (which changes if she's fighting Otane). The North American Super NES version also replaces the endings that were in the Japanese Super Famicom version with a congratulations screen with the character portraits used in the pre-fight screen.
