The Chameleon is the secondary antagonist in T.U.F.F. Puppy. He attempts to destroy T.U.F.F., but he never succeeds. He often uses his transformation suit to transform himself into any form, upon taking an objects form he also gains all its features, Ie. turning into a bus, he can drive, turning into a gun, he can be fired etc. He can also change his voice, although for some reason he doesn't always do this. Physically his reptilian attributes serve him well, he can climb walls and can use his long tongue to grab hold of objects and people, and carry them.
