Corroder's car keychain is a pair of crossbones with a miniature version of his own head taking the place of the skull.
The comic that depicts the events of this episodes told some minor details quite differently. The clash between Furno and Corroder in the TV show is short, the combatants hit each other only a few times, and it has a humorous scene during which a huge metal bar gets stuck in Corroder's mouth. In the comic, the fight is more violent, and Furno hits and kicks his opponent several times. Also, at the end of the comic, the villains give a briefing to their employer, Von Nebula. In the series, Von Nebula appears first in the third episode, and is alone.
