"Kansei! Don Onitaijin! Yo! Ginga-ichi![1]"
―Combination announcement in the DonBlaster[src]

Dai Gattai Don Onitaijin (大合体ドンオニタイジン Dai Gattai Don'Onitaijin, "Great Combination Don Oni-Exterminating God") is the main Giant Robo of the Donbrothers in Avataro Sentai Donbrothers.[2][3]


The combined form of the core Donbrothers in their Robotaro forms, Don Onitaijin is unique in being able to alter its size from average human height to towering mecha height. The mecha is controlled mostly by Don Momotaro, while the other four can take control from their respective components. Don Onitaijin is armed with the Kiji Swords (キジソード Kiji Sōdo), which are stored on the back Sashimono-style, and the black gunbai-based Donbai (ドンばい) military fan. It is capable of moving at great speed despite its armored appearance, and utilize Kiji Brother Robotaro's wings mounted on the shoulders to achieve the power of flight. Some of its attacks include:

  • The Oni Kick (鬼キック Oni Kikku) rapid-fire kicks with the Oni Sister Robotaro right leg.
  • The Continuous Sky Monkey Strike (天空猿連撃 Tenkū Saru Rengeki) series of punches with the Saru Brother Robotaro's arms.
  • The Kiji Missile (キジミサイル Kiji Misairu) pheasant-style rockets fired from Kiji Brother Robotaro's beak.

Its finisher is the Matchless Peach: Donbro Paradise (一騎桃千・ドンブラパラダイス Ikkitōsen Donbura Paradaisu), where Don Onitaijin combines the Kiji Swords to enlarge them before generating six energy peaches that fuse to one on the Kiji Swords. The blade is then encased in pink flames before slicing the Hitotsuking in half upon its destruction.

According to Taro Momoi, the only downside of this mecha is that this formation weakens Taro in the brief moments after Don Onitaijin finishes a battle.
