adokargo (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. It pinches at Mega Man, leaps, and shoots bombs. Its weak point is its brain, which is protected by its shell. When hit by a charge shot or one Mega Ball, its brain is exposed. Yadokargo reappears when revisiting the stage, but it can be easily be taken out with Flash Bomb or Tornado Hold, and can be destroyed instantly with Astro Crush (regardless of protection from its shell).
