Mazinkaiser comprises the weapons of the two previous Mazingers and adds a factor of uncontrollable energy associated to them (for example, sometimes it's hard for Koji to keep the mecha stable when using the two attacks previously mentioned). All Mazingers, except God Mazinger, have "Rocket Punch" attacks, in which they launch their arms as projectiles, which return after being shot towards the enemy. Grendizer has few similar weapons, but it even expands its arsenal with several large ships that give him different capabilities, such as the Spaizer, Double Spaizer, Drill Spaizer, Marine Spaizer and other related machines. (These are also called "Spacer") Hover Pilder Traditionally, Mazingers are controlled thanks to a flying vehicle that docks on the mecha's head and activates it. The first one, built for Mazinger Z, was the Hover Pilder, a small hovercraft, later replaced by the Jet Pilder. In Great Mazinger, this device takes the form of Brain Condor, and in Mazinkaiser it's called the Kaiser Pilder, which resembles Brain Condor more closely due to its sharp shape (in contrast to Mazinger Z's Pilder, that had a more bulbous shape) and the way it rests on Kaiser's head, leaving one of its fins standing vertically like the crest of a rooster. These aircraft are always red, except in the Mazinkaiser OVA version of Mazinger Z, where the Hover Pilder is white. Grendizer doesn't have a small aircraft, instead the robot itself is fitted inside a larger ship called the spazer for aerial attacks and the robot can launch from it when ever there is a need for a ground battle. Some times Grendizer can stand on top of the spaizer and use it to fly so it can have more freedom in aerial battles. Jet Scrander / Jet Scrambler Mazinger Z wasn't conceived as a flying robot, and hence he is later equipped with Jet Scrander (or "Jet Scrambler"), a detachable device that allows him to face aerial monsters. This machine also had razor-sharp wings that could be used to cut enemies while in flight. Great Mazinger has an incorporated Scramble Dash, that can retract itself when not needed. However, he is also given Great Booster, a very powerful device that attached itself to Great's body pretty much the same way Jet Scrander did to Z's and allowed him to fly at higher speeds. Mazinkaiser has Kaiser Scrander (or "Kaiser Scrambler"), which is very similar to
