SUPERSAIYAN5RADITZCONFIRMED!!!SUPAOMEGAGENKI-DAMAPOWA!!!!!!OVER9000!!11!!ONE!!1MILLIONSUPERSAYIANS!!!!
Released yesterday is a new trailer for DBZ: Ultimate Tenkiachi's character creation system. And yes, you can make your own Dragon Ball AF characters like SSJ5 Goku or a SSJ3 Raditz. You can create your own character's looks (or build off of existing character templates e.g. Uub), outfits, transformations, and surprisingly.. even their finishing moves.
So far it only shows off Human & Saiyan male customizations, so there's no idea yet if you will be able to make a female character (let alone a Female SSJ) nor the ability to create a unique alien character using existing parts of characters like Frieza, Cell, etc. Hopefully you'll be able to, Saiyans & Humans are only fun for so long.
