I never liked Chameleon Boy of the Legion of Super-Heroes much. The whole idea that he could turn into a giant beast seemed silly. I mean, if you can turn into Godzilla every time, why not do so? Furthermore, why not get rid of those silly 1960s-era antennae?
And the whole "R.J. Brande is really your father locked in human form" story line was soap opera nonsense.
He was in the animated TV show, but more for comic relief (just like Beastboy was on Teen Titans). Thank god they kept him out of Smallville.
