If Cell says he's a SSB, he is. Why would Akira have him state he was a SSB if their was no point to saying that? I think Cell is a SSB, He's shown power already to destroy KIng Kai's Planet that had 5 times the dense than Earth and nearly destroyed everything in the self destruction. He was also proven to hold a Kamhemha at Gohan with all the Z fighters blasting him a trillion times, It took Vegeta to blast him into loosing his grip. Cell is actually bad a** and is my favorite DBZ villain. First villain to ever talk about perfection.
buff form was never really explained, but this is the way I understood it: DBZ characters uses ki energy to boost their speed, strength, durability, or they can use it as energy blasts. When someone goes to buff form, he is using his entire ki to boost his strength, while he lefts very little energy for the speed. Is this correct?
