Yaaaah! Go mini-games. Forget about, future trunks, or bayby trunks, or Gotenks, lets have baby trunks! He'll fly on a nimbus, and everyone catches him!!!!!!!!! :S
Come on, no one is weak enough to use the nimbus who could seriously get involved in ESF.
;/ Unless perhaps you could have it move while you were firing, like a moving platform, so you could keep moving even while shooting a guided attack.
But that's a bad idea, so, I don't think the nimbus is needed.
