Spiky John is one of Bowser's Koopatrols guarding Princess Peach's Castle during the events of Paper Mario. Spiky John and his two friends (Mr. Hammer and a Koopatrol called Spiky Tom) were going to have a quiz show; however they needed one more person. Princess Peach showed up just in time and they all decided to let her play. During the game, Spiky John is only rarely able to successfully answer questions. Immediately after the quiz ends, Spiky John leaves the room and is never heard from again.
