Okay so I had a big argument with some guys on chat (won't name them) and they said that the potara fusion of Goku and Vegeta (Vegito of course) could beat the potara fusion of Goku and Gohan (Gokan).
I argued that Ultimate Gohan was in a completey different league than SS2 Vegeta. I proved this by explaining that Gohan could beat Super Buu with Gotenks absorbed but Vegeta couldn't beat Majin Buu. Of course I've acknowledged the fact that Elder Kai said that the fact they were rivals makes them stronger but surely their power can't be that much stronger just from that.
So was this just crazy chat or is there some reasoning behind this idea?
