Evil Kevin circulates online as a short soundboard and meme audio clip rather than a clearly credited scene, so its popularity comes from how creators reuse it. Editors drop the name as a punchline when an ordinary moment suddenly turns scheming, turning Kevin into a mock villain character for that video alone. The clip travels well because it is brief, recognisable from the title alone, and easy to layer over gameplay, skits and reaction edits without needing any context from a longer source scene or story to understand the joke.
