Grammar Gorilla is a supervillain in Stick City. Grammar Gorilla goes into an unstoppable rage whenever someone else uses bad grammar, despite his own grammar being regularly terrible. In his first confrontation with Captain Hippity and Science Guy, he runs off after Science Guy splits an infinitive. He later returns to be recruited by Colonel Tigh Ming to be a member of the superhero team The Harassers, as supervillains tend to use worse grammar than heroes.
