You have to pick:

Would I gain a power or would I just be a member and attending all the luncheons?

Or, perhaps, become one of the existing members (eg Wolverine, Cyclops, etc.)

You'd have a power (you can't be a member otherwise). The power would be on par with a typical x-man.

A good atheist, a good satanist, and a good Hindu are three every different people. What constitutes a "good person?" Do we only have one incarnation to an animal after we die as a human, then we die forever? Or is this a cyclical kind of thing? Do the animals and plants (f*cking plants, really?!) have to be "good" to reincarnate? What determines if a fern or plankton has been good or bad?

@RbrtKurtz: I don't know. But you might want to find out. :P
