I mean. You know how they brought him back with the dragon balls. What if they didn't. He would have been killed off with raditz. I mean look at raditz no one gives a shit about him anymore. Same would go with goku. But to be on topic goku would totally pwn the siver surfer. Goku is stronger than anyone that marvel can bring. Silver Surfer=8999 < Goku = OVER 9000!!!
