Story

Majin Boo is tired of waiting, leaving Piccolo no choice but to take him to fight Gotenks early...

... lest Boo destroy Kami's Temple and everyone on it while the kiddos train in the Room of Spirit and Time.

Inside the room, Goten and Trunks have already far surpassed a Super Saiyan and are preparing for their epic battle, with the hope to make it exciting and nail biting.

But Piccolo wonders will their strength, after just over a week of training inside the Room, be enough?

So far, no.

Seeing his one audience member not entertained by his antics...

... Gotenks decides to take the fight seriously...!!

... that is, if he can think of a new, exciting special move to use.

ffs

What's cut?

Nothing.

Between Gotenks and Gohan, maybe you shouldn't leave the fate of the Earth in the hands of Grade Schoolers?

 It's High Schoolers who get it done.

Nevermind.
