if you get banned again you can use the fusion technique with your 2 previous accounts and come back as gogeta and then you will be so powerful that not even a ban can stop you. and if rowen starts acting all janemba like then you could go ss4 and be like, "bitch! do you see my tail?! you think you can mess with the strongest saiyan this universe has ever seen!?" then you could spirit bomb the shit out of him.
the problem with that is the fusion would only last 30 mins, so after that goku and vegeta would both be tired out from ssj4 and being fuzed so rowen could be all "i am complete" and ban hammer the hell out of me
