Quiz is the blue alien in RT2. Making his cameo in RS5 in the first cutscene, he then reveals his plot to take over Vizion once RT2 begins. He then becomes the headmaster of the original Riddle Elementary. Once convinced by Phil that Vizion was a bad idea after all, he lets the kids go only to find that Diz has taken over Vizion instead. Quiz then sacrifices himself to destroy Diz and end Vizion entirely.
