It is in the arena FAQ. Basically it is normal human, powered (which encompasses a broad spectrum-fighters haggle powers to roughly even themselves out) and god-like.

I usually just stick to the lower end really of powered though my only arena fighter is human, not counting Jacer who is in the multiverse thread right now. I'm just slowly fleshing out his world bit by as I wait for that to get fleshed out and started.
