Anyhow, maybe the Hulk Model was left over when Champions was supposed to be Marvel online? Of course they tweeked his face so it wouldn't violate copyrights. Also, having him in is Cryptic's way of giving a wink and a nod to the Star Trek / X-Men crossover comics.
I'll have to keep an eye out for other Easter Eggs. The only one I saw in Beta was Admiral Harry Kim Culver. (People will be sent there on a mission and beam down, where it looks like K-7. Harry Kim is in the Admiral's office).
I second FoxyWar's comment about the scantily clad chick on the right. All the fuss over a green dude in purple pants when there's a relatively good looking CG female wearing a very Liea-esque swim suit to discuss?
Is a pretty random and somewhat comical find though.
