Green Devil

The Green Devil (グリーンデビル) is a improved version of the Yellow Devil that appears in Mega Man 8 and Mega Man & Bass. His body is made of a thick slime-like substance that can be manipulated by the eye in the center.

In Mega Man 8, he is the boss of the third Wily Tower stage and attacks like the other Devils, except he can turn his goo into spikes or rush forward as a wave of goo. A feature unique to this Devil is that its eye is covered by a bubble-like coating, preventing shots from hitting it in humanoid form. It must be peeled back by striking it with attacks (the Flash Bomb instantly does this), then striking the eye, preferably with Thunder Claw.

In Mega Man & Bass, the Green Devil is the first boss and covers King's escape from the Robot Museum. It is weaker than the Mega Man 8 version, and receives twice damage from the Mega Buster/Bass Buster. It cannot dismantle himself across the screen to attack. Instead, he stands in the same place and throws parts of his body at the enemies. Like the previous version, the coating must be removed, but only the Mega Buster/Bass Buster will be available for the first battle. Unlike other bosses, the Green Devil will always reappear if the player return to the museum stage, and Remote Mine can defeat him with one hit if used by Mega Man and two hits if used by Bass. He can also be killed by the Copy Vision if Mega Man uses it.
