A referee of robattling, Mr. Referee somehow manages to appear before most daytime robattles or, least, those that involve the characters shown in the anime (it is speculated that he may be one of many referees designated to different parts of Japan). He is known for his catchphrase: “Then it's agreed! This will be a submission robattle. The first Medabot to cease functioning loses, and the loser must submit one Medapart to the winner, for keeps. I shall act as referee, me Mr. Referee, so no one gets hurt. Medafighters ready? Medabots, robattle!”
