Batman uses prep nuff said
Batman dies horribly. His prep only works for people with a weakness. And Goku doesn't have any notable ones.
What about food? lol
LOL that's everyone's weakness bro. What is Batman gonna do? Take all the food away? Maybe eat it all and become Fatman.
@SpeedForceSpider: Lol, it's not Superman's weakness. Just throwing that out there.
