Tee Hee.
Scooby-Dee Imposter is a member of The Nega-Fergo Bunch. It's a h*mophobic version of Scooby-Dee (Who only appeared in one episode of the Scooby Doo Show). He dressed like it to try and kill Scooby-Dee as Well as Scooby-Doo and Scooby-Dum. He takes orders from his intructor. Even though there's a male dog underneath the dog thinks he's really a girl and that's why he joined The Nega-Fergo Bunch.
