|Game||Super Smash Bros. for Nintendo 3DS / Wii U|
The Yellow Devil is a non-playable character in Super Smash Bros. for Wii U and 3DS. 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, the characters can defeat Yellow Devil by attacking his only weak point: his eye. When the Yellow Devil is defeated, he explodes, and it can deal a lot of damage to the characters, except to the character who defeated the Yellow Devil.
The Yellow Devil first appeared in the original Mega Man for the NES. He is the boss that you encounter in Wily Fortress Stage 1, and its weakness is the Thunder Beam, Elec Man's special weapon.
Some of his other appearances include Mega Man: Powered Up, Mega Man: The Power Battle, Mega Man 2: The Power Fighters, Mega Man: Battle and Chase, and other spinoffs and remakes.
