The line belongs to William Afton, the murderer behind the animatronics in Five Nights at Freddy's, and it is most closely associated with Springtrap, his decayed springlock suit form in Five Nights at Freddy's 3 from 2015. Fans clipped the menacing promise from gameplay and cutscenes, then reused it in edits, memes and short videos whenever a villain, streamer or rival made an unexpected return. Its staying power comes from that simple idea: no matter how completely Afton is defeated, the story finds a way to bring him back.
