The Yellow Devil is a non-playable character in Super Smash Bros. for Nintendo 3DS/Wii U and Super Smash Bros. Ultimate. He is a stage boss for the Wily Castle Stage. He jumps out from the background and when he arrives on the stage, he will disassemble and reassemble himself on either side of the stage. Similar to his various reincarnations in the Mega Man series, fighters can defeat Yellow Devil by attacking his only weak point: his eye. When the Yellow Devil is defeated, he explodes, and can deal an excessive of damage to other opponents, except the fighter who defeated him.

Trophy Description


This massive baddy splits itself into small pieces and flies across the battlefield, striking anyone in the way. Deal damage to it by attacking the eye, or hide behind its body to avoid your foes. Be careful— whoever deals the final blow triggers an enemy-launching explosion!

  • Mega Man (12/1987)
