I like this idea and would like to join!

I have a myriad of interesting characters I could use...

Richard the warlock for one
Maybe Gene the god hand
Oh, or If I really wanted to stir shit up... Twilight Sparkle the Neurotic OCD Princess Book-nerd.

PFFF... This is what I like about multiverse scenarios, anything is possible [barring breech of GM set rules of course] and no matter what one person or the other picks, it's always bound to become something wild and uniquely entertaining. I get to really exercise my imagination and step outside of the standard comfort zone I get used to interacting with the usual single world RPs.

Hmmmm... Would 'TF2 Freaks' fall under the label of OCs? Being that they are customized versions of the game's classes?

Hmmm, what about 'story-wise' god characters that are nerfed? such as one who's source of power is related to something from their world specifically, and being away from their natural location would drastically reduce said power to a far less godlike level?
