MadPat (or Anti Matter) is the evil alter ego of MatPat. Not much has ever been known about him... until now, that is. He isn't any Antisepticeye or Darkiplier, but he's still an ego, and he's still evil. MatPat doesn't say anything about him, kind of like Nate doesn't say anything about Natemare.
MadPat is insane. He is completely psycho, and unlike most egos, he doesn't like to stick with the same side. He often alternates, making him unpredictable.
He often isn't seen, but he's heard a bunch. He often carries around a chainsaw that he somehow attached to a flamethrower, and wears an empty Freddy Fazbear suit, kind of like the games.
