Percy is a supporting character in the Calling Cat-22 series of Wedgies, appearing in three out of five episodes. Percy is a large, yellowish bulldog in a dark-blue-and-red-striped shirt and a spiked red collar. Percy is unbelievably stupid and rather aggressive; on one occasion, he doesn't realize that Cat-22 is a cat even after 22 loses his none-too-convincing disguise, and on another, he swipes 22's bone and, when asked to return it, bops him over the head with it. He is capable, however, of a certain level of sarcasm, as when he asks 22 if he needs to be shown how to "use" a fire-hydrant.
- Percy's name was originally going to be "Buster."
