The actual appearance of Evil Tim is unknown. Before Ed gets the idea for his scam, he saw Edd dressed as a hunchbacked monster with large clawed hands and claimed it to be the "Curse of Evil Tim." His statement may imply that Evil Tim, or a monster that Evil Tim summons, has this appearance; however, given that this occurred shortly after he had been interrupted while reading the comic by Eddy, it may have been his overactive imagination at work. Other statements Ed makes imply that Evil Tim summons a monster in the comic in order to, in Ed's words, "dissect our organs and feed them to the minions of Hades".
