Z in the fourth episode when one of the Chaos Emeralds wound up in his lab. His studies of it allowed him to create an Emerald Radar, which he supplied to the heroes once he learned of their quest. He then gave them a lift to Yoshi's Island on his Super Poltergust 3001 in the fifth episode, but returned to the safety of his lab in the sixth. He then sent Stuffwell to aid them and attempted to assist Prof. Frankly in episode seven. When the princess was kidnapped in episode eight, he purchased several items for the heroes and upgraded Mario's Sky Pop to attack the Omega Doomship."@en . "Professor E.
