Majuub

Well, Piccolo's intelligence would be a great asset, but Gotenks has so many tricks up his sleeves it's not even funny. Galactic donut, Buu Buu volley-ball, Super Ghost Kamikaze attack. He used the ghosts as SSJ and he it seems it was one of his most powerful attack, now imagine him using that as SSJ3, ther power and speed would be much greater.

Gotenks has so much Ki within himself it's really impressive. He used all kind of overpowered technics but he was still able to take on Shin Buu. Maybe his close combat skills aren't as great as his long range technics, it would explain the fact that his direct punches and kicks didn't damage Shin Buu too much. For all we know he lacks talent in that area because he lacks experience and intelligence. His Ki-based technics were so...silly. Gotenks is a really unpredictable fighter, so I wouldn't doubt even with Piccolo's intelligence, Buu would fall in one trick or two. If it's a technic Gotenks really put his energy into, then we all know what Buu will look like after the blast...
