Actually, given that we have no understanding of just how powerful the robo-trousers are and Wallace's Were-Rabbit transformation only being vulnerable to gold bullets, it's entirely possible for Wallace to beat Goku.

DBZ Youtuber. Wanks power levels a lot. I think he made the videos "debunking" Death Battle's Goku v Superman videos.
