I think this supposed to be a nod to Dr. N. Brio in the first Crash game. After you drain his health he drinks two vials of mutagen and turns into a monster.

There is such a Crash Bandicoot campaign. This campaign has its own skins for first aid kits and tanks. And there was a skin on the tank. It looked about the same as this skin, but better. And so yes, I agree with you, he looks like a Hulk.

Never played Crash Banicoot before, but are you sure this isn't a Hulk Skin for the Tank? I mean Green Skin, Purple Pants?
