The Chameleon

"It is I, the Cham-ah-lee-on! Oh, drat! I mean the Chameleon!" - Chameleon

The Chameleon (voiced by Daran Norris) is a villain of T.U.F.F. Puppy, and serves as Set's evil right-hand man. He has a transformation suit that allows him to change himself into anything and anyone. Set promised him that he will destroy T.U.F.F. headquarters if The Chameleon helps him destroy Jaden and his friends. He is also a most dangerous enemy of the Rainbooms.

He is part of the Heylin side, as well as Set's second-in-command.
