i think using dragonball names is extremely lame, and yes that means every ssjradtizbardok123123 and every namekian with some form of piccolo in your name.
Yeah whats the point of playing dbo if your using a dragon ball name, unless its a pun. I put some thought into my name and got Caulli (cauliflower) and then made a pun DemonSenior (DemonJr.)
