Jet Scrander in its colour scheme (red and yellow) and the fact that it's not part of the mecha but connects to it when required. Notably, since Kaiser can't use his chest plate as boomerang (a Great Mazinger gimmick) he uses Kaiser Scrander in a similar fashion, due to its sharp wings. The Shin Mazinger incarnation presents the God Scrander ("God Scrambler"), which appears on the first chapters and in the latter part of the series. It also allows Mazinger to use a new attack, the Big Bang Punch, which consists in Shin combining with the God Scrander and transforming into a gigantic hand, and later making a fist that immediately turns golden-coloured, and is used as a scaled-up Rocket Punch. During the transformation, the God Scrander would compose three of the "fingers", and Mazinger uses his arms as the other two. Female mecha Mazinger pioneered the concept of female mechas that, while not nearly as powerful as the main robot (with the probable exception of Minerva X, as she was designed to be a direct counterpart to Mazinger Z), play a significant role in the battle against the enemy. Their most noticeable characteristic is their main weapon, the Oppai Missiles, missiles posing as breasts placed on the mecha's chest. Again, Minerva doesn't follow this canon completely since her breast fire is identical to the male Mazingers, and she wasn't controlled by a human being (until her appearance in the Mazinger Angels series). No female mechas were included in Grendizer, but characters like Hikaru and Maria prove to be helpful and brave in battle. They are (in order of appearance): Aphrodite A, Minerva X, Diana A, and Venus A. Notably, in Mazinger Angels, Minerva has a special berserker mode, the "Sirene Mode", in which she takes a form similar to that of Silene, a character from Nagai's Devilman. Shared characters Many characters appear in different points of each plot. Kouji Kabuto: The original Mazinger Z pilot reappears towards the ending of the Great Mazinger series, again piloting Mazinger Z. He then appears in Grendizer, but this time he does not pilot a mecha but a spaceship, and later the Double Spaizer. Koji becomes the pilot of MazinKaiser in the most recent incarnation of the series. Sayaka Yumi also appears in the three main Mazinger sagas. Dr. Hell: Mazinger Z's nemesis, this evil scientist dies at the end of that storyline,
