Human-Expert Matt, or Impostor-Handler Matt, is the Mirror Island version of Monster-Handler Matt that appeared in episode nine of My Singing Monsters Live. He is often mentioned in episodes after episode nine. He looks like the monsterized version of Monster-Handler Matt that is shown in the intro for every My Singing Monster Live episode. He might actually be Monster-Handler Eric, because one, he wasn't in episode nine, and two, Eric mentioned in episode 14 that episode nine is the only one he hasn't watched. Since he is from a Mirror world, Human-Expert Matt gets "stamped" when he gets trivia correct, while Monster-Handler Matt gets "stumped" when he is incorrect.
