The list is really everything i got. It went like this...
My dad is a tatooist. He works on his tatooes upstairs on his PC. My room is next to it where I was playing Smash Bros Melee. The jappo that my dad was tatooing went upstairs to help my dad edit the tatoo on the computer, and saw I was playing Melee. Then, he said he knew Sakurai and knew some characters that was considered for Brawl. I didnt believed him, but he had pics of himself and Sakurai. And that was BEFORE Brawl was released, yet he mentioned all the characters that joined. That was proof enough for me, so I felt like sharing the info. But i understand i looks like a lier. But please, dont flame and debate which of the characters that are most likely to join.
And with Rival trainer, i think its the same as Pokemon Trainer. He shifts between Eevee, Hitmonlee and Blastoise.
