Mael Radec isn't really a villain, Just a soldier on the other side following orders. It would be interesting to see how he reacts storywise to other characters.
"I was faithful to Radec from the beginning!! How many others can say the same?!"
The trouble with finding a villian and/or boss because you just cant take one characters nemesis and expect a diffrent character to fight him for no reason. So (as polygon man for an example) they have to take Sony's real world nemesis ( or just do a mario brothers and make a giant hand) and put him as a villian. My idea eould be to use Playstations hated organization leader due to the 7 month wait due to hacking... Non other than ANONYMUS (Spellcheck?) And having him with a ? Mark head ( their logo) and having him fight.
Oh my god, how did I never think of that. It's a brilliant idea but I don't think they want people to really remember the little incident or really want to give more fame to the group, maybe a little easter egg should be put somewhere. I do also support Kevin Butler and the bar from the Michael commercial around the end to fight in.
As for what people are saying for Cole, I think having skins for him rather than separate characters would be alright because it would be easier and better looking on the character slots. Skins/Costumes that can be used in Cole could include Reaper Cole, Kessler, Vampire, Good, and Evil.
If Goku gets thrown into the game, then I'd love to see Vegeta be his storyline enemy
