The Auditor cuz the only 2 things he can be dispelled by is the Tricky (the evil zombified Ronald McDonald clown) and the halo power
He also revives in the madness version of the underworld instantly and cannot be hurt by anything else.
Not to mention that he could pause time and give himself buffs while rebuffing sonic.exe and also possess things and make them nearly invincible.
So the auditor could win. For those non-believers, watch the madness combat series. Then you would understand.
