Trapped in Forever

Gotenks succeeds with his attack, or so it seems, after blasting Buu to microscopic pieces, it appears the monster has been destroyed, but no, there is still enough of him left to regenerate. Gotenks acts as if he has no power left so he can make his next move a surprise, but Piccolo blows up the door to the Hyperbolic Time Chamber, trapping himself, Gotenks, and Majin Buu inside forever.
