- Screaming Scott
- Bandana Bendito and Harry "The Spleen Crusher" Jackson
- Professor Moshimo (mentioned)
- The background for the boxing ring in this episode is a redesign of the arena from the season 1 episode Robot Love.
- Tommy, Lola and Gus make dummies from old bins for Robotboy so that he can destroy them and so that Tommy can test the oil. These dummies are propose to be villains. Gus made a dummy that looked like Donnie, Tommy made a dummy that looked like Dr. Kamikazi (altough it was not mentioned in the episode itself that it was Kamikazi) and Lola made a dummy of General Yakitori. This was odd because she never appears in episodes with Yakitori or never met him. (It's possible she found out about him off-screen.
- It's unclear if the white markings on Robotboy's body when he uses the formula appear in real-time.
