SSJ2 Gotenks vs. Kid Buu

Who wins?

Gotenks.

If nothing else he can just Kamikaze-Ghost the shit out of Pure Buu, like he did to Super Buu. That should incapacitate him long enough to constitute a forum win.

SSJ1 Gotenks was equal to SSJ3 Goku. So SSJ2 is overkill

Gotenks obliterates him, even pre-Rosat.
