Yadokargo (ヤドカルゴ Yadokarugo) is the boss of the opening stage in Mega Man 8, a crab-like robot that protects Dr. Wily's secret base, and accumulated moss on its shell due to the long time it stood still. He pinches at Mega Man, leaps, and shoots bombs. His weak point is his brain, which is protected by his shell. When hit by a charge shot or one Mega Ball, his brain is exposed. Yadokargo reappears when revisiting the stage, but he can be easily be taken out with Flash Bomb or Tornado Hold, and can be destroyed instantly with Astro Crush (regardless of protection from his shell).

Other appearances

Yadokargo appears in the first chapter from the Rockman 8 manga.



  • His name is derived from "yadokari", Japanese for hermit crab and possibly "escargot", French for snail.
  • Even though he's an end stage boss with a health bar, the game's mini-boss theme plays throughout the fight rather than the normal boss theme.
  • The boss introduction is slightly different between the PlayStation and Saturn versions. In the original PlayStation version, Mega Man stands still for a few moments, then a lone bird flies away when the music track loads and the robot reveals itself. In the Saturn version, the animation of the flock of birds from the beginning of the level was added when Mega Man stops for a few seconds.
