Mega Man series
The Yellow Devil can be difficult to beat, because of his complicated attack pattern and tendency to change forms after getting hit once or twice. Once the Devil is about to transport to another space, Mega Man (character) must avoid the parts and shoot his eye with the Thunder Beam or Mega Buster and avoid the shot.
Mega Man: The Power Battle and Mega Man: The Power Fighters
The Yellow Devil only made appearances in Mega Man 1-2 and Mega Man 3-6 in Mega Man: The Power Battle in Wily's Fortress. The Yellow Devil is same, but he has more attacks. He can grab Mega Man with his hand, throw a part of his body, which absorbs him with his arm to launch them and separating the smaller version of him to transport. Without the Thunder Beam, Mega Man must shoot his eye with different weapons or the Mega Buster. Defeating him advances to the Wily Machine. Rolling Cutter in Mega Man 1-2 is the best weapon at his eye, while in Mega Man 3-4, the best weapon is Dust Crusher. Mega Man must avoid the beam from his eye. The Yellow Devil also walks and jumps.
In The Power Fighters, the Yellow Devil only appeared in the episode, "Rescue Roll!". He behaves like the one in the first game, except now he can use Thunder Beam. Defeating him advances to the Wily Machine.

- EU: "This towering foe splits himself into small bits to move across the stage and wreak havoc. If you can get behind him, you can use him as a shield and also hit his eye more easily. Hit his eye enough and he'll explode! Try to get your opponents caught in the explosion to do some real damage!"
