Nitro Man is one of the eight Robot Masters introduced in Mega Man 10, the 2010 Capcom platformer, designed around a motorcycle with wheel-themed armor. His accelerate sound comes from his boss fight, where he revs up before charging across the arena at high speed. Fans of the classic series ripped and shared short clips like this one on soundboards, where retro Mega Man effects remain popular for edits. It endures because the rev reads instantly as cartoonish velocity, even for viewers who never played the game.
