Toiletnator

The Toiletnator is a recurring joke character from Codename: Kids Next Door. He is, obviously, a toilet-themed supervillain, a motif that has no clear justification even compared to the show's other villains. He is seen as a non-threat by KND operatives everywhere and shunned by other villains to the point that they take deliberate measures to keep him away from their villainous meetings. Despite all this, he is incredibly enthusiastic about being a villain and completely oblivious to the fact that no one wants him. His "powers" include several toilet-related abilities such as shooting toilet paper from his arms.

In the episode Operation: F.L.U.S.H., Toiletnator decides to prove himself worthy to the other villains by defeating the KND in their treehouse. However, because the members of Sector V were away at the time, the other villains had already taken over the treehouse without resistance and as a result the empowered Toiletnator defeats his own allies, mistaking them for the kids, who arrive right afterwards just when his sudden burst of competence wears off.
