 	The Chameleon 	Daran Norris 	The Chameleon is a major antagonist in T.U.F.F. Puppy who wants to get revenge on Kitty Katswell for putting him in jail (reasons unknown). He can disguise himself as any person or object using his transformation suit.
 	Bird Brain and Zippy 	Rob Paulsen and Grey Griffin 	Bird Brain - Bird Brain is an evil criminal genius and mad scientist. He's a blue-bottomed booby who can't fly, so he uses gliders, cannons, and other flying contraptions he built, and has problems finding decent henchman to help him. He does have a little hummingbird ally named Zippy, who is completely oblivious to the fact that he can't fly and constantly tells him that he can fly if he believes.
Zippy - Zippy is a hummingbird that acts as Bird Brain's partner in crime. She is always trying to encourage Bird Brain that he can fly on his own as long as he believes. In Thunder Dog, she annoys Bird Brain a lot with her new catchphrase. She was the one who hired Bat and Owl. Zippy doesn't seem evil, so it is unknown why she is working with Bird Brain.

It is lead by Verminious Snaptrap and usually commits crimes that involve world domination.
