Deimos is a fan-favorite operative from Krinkels’ Madness Combat, the long-running Flash animation series that began in 2002. He returned as a playable character in Madness: Project Nexus, the 2021 run-and-gun indie game by Cheshyre set in the same universe. Short voice bites labeled as Deimos lines, including this confident “Oh yeah,” circulate on fan soundboards and in gaming edits. Its appeal is simple: a recognizable character, a universal phrase, and a length that fits anywhere, which keeps it in rotation for memes and montages.
