Springtrap is a dirty and wither springlock suit with a rotten corpse inside of it. It is possessed by the infamous William Afton or Dave Miller, the co-founder of Fazbear entertainment, the kidnapper and killer of children, and the abusive father and husband. He’s wicked, cold-blooded and methodical, messed up in the head, and says things out loud that he shouldn’t. He’s also a good liar. He has done all of this so that he could become immortal and his plan worked. He always comes back.
