The similarities between Goku and Superman are many. They are both aliens from a distant planet. They both had their home worlds destroyed and were believed to be the last survivors of their race. They both became defenders of good, and adopted Earth names. And most importantly, they are both incredibly powerful characters.
It’s only natural fans would want them to square off at some point, so Screw Attack’s Death Battle series made it happen. Twice. Looking at the powers available to each character and factoring in their vulnerabilities, the Screw Attack team engaged in a bit of fanfiction to pit the Super Saiyan against the last son of Krypton. And Goku lost. Both times. But if it’s any consolation, the first time they battled, it took the destruction of the entire planet for Goku to go down.
