Professor Moshimo

A bad relationship. He was his mentor at the Gottinhimmel Academy for the Wealthy and Smart, which implies they may have been once on good terms.

He once tried to kill him by tricking Robotboy (who he tricked into thinking he turned into a real boy) that Moshimo was going to turn him into a robot slave, which lead to Robotboy attempting to murder him. This was stopped by Tommy though.

A bad relationship. He treats her poorly and dumps her into water if she annoys him. Though he can act kind to her when he is in danger as shown when Robotboy attempted to kill him.

Dr. Kamikazi

A bad relationship. He regards him as a "criminal lowlife".
