Tigers and wolverines have one big thing in common and it's that the government likes to oppress them. It doesn't matter if you're the animal or a mutant X-Men hybrid. The government will go out of its way to oppress you if you are one.

Tiger and wolverine people are so oppressed that the only thing they're allowed to amuse themselves with is Gak (ぎゃく). You know, that weird goo they made us play with when we were kids? Well that's not so fun when it's all you have.
