ok everyone, i think the nimbus should be different speed accordign to your size, because, as a child, goku could go faster tahn speed with it. but as an adult, he could fly faster than it. so freeza would be the fastest on it at transformation 1, but would loose speed in 2 as he is so big. buu trans 1 would be slower than trans 2.and the ss trans would become faster as they are more skilled or woteva, somthin like that. and i bilieve you could fire beams on it at other people and ram into other people on nimbuses. but you can only ride them in team modes as if you kill somone on your team, u become impure and can't ride it for the remainder of that match.
