Enemy Controller originates from the Yu-Gi-Oh! anime and trading card game, specifically associated with the character Seto Kaiba. The meme gained massive traction on the internet through Nico Nico Douga and YouTube remixes (MADs) where Kaiba's button-pressing sequence—'Left, Right, A, B'—was synced to high-energy music. In these videos, Kaiba is often depicted performing synchronized dances or manipulating other characters like puppets using the card's 'command' inputs. Today, the meme is used to humorously represent taking control of a situation, following a complex sequence of events, or simply to pay homage to the legendary intensity and flamboyant movements of Seto Kaiba during a duel.
