Green Devil

The Green Devil (グリーンデビル) is an 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, Green Devil is the boss of the third Wily Tower stage and attacks like the other Devils, except that he can turn his goo into spikes or rush forward as a wave of goo. A feature unique to this Devil is that his eye is covered by a bubble-like coating, preventing shots from hitting it in humanoid form. The goo must be peeled back by striking the chest with attacks (the Flash Bomb instantly does this, as does the Arrow Shot and Laser Shot), 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. He is weaker than the Mega Man 8 version, taking increased damage from the Mega Buster/Bass Buster and having much fewer invincibility frames than standard bosses. He also cannot dismantle himself across the screen to attack. Instead, he stands in place and throws parts of his body at various speeds and angles at the player. Like the previous version, the protective eye coating must be removed, but only the Mega Buster/Bass Buster will be available for the first battle. However, unlike other bosses, the Green Devil will always reappear if the player returns to the museum stage, and Remote Mine can defeat him in two hits (if playing as Bass, 1 hit for Mega Man).
