Actually when all the gamers on a forum got together and did the math and stats on it, Goku pwnt him in like 10 seconds without leaving SSJ2. And that's his uber godly comic incarnation. Pretty much only Hulk, Dark Phoenix, maybe Apoc, and Wolvy had a chance (the last because he was damn near impossible to kill, short of utterly destroying the planet...so no Wolvy Vegeta matches, since Vegeta would do it out of spite).
