Huh... The battle between Goku and Superman will never end until they actually fight. People that believe Superman would win state that, "Superman came first" or because "Superman is an icon." Now I'm not saying I don't like Superman. I like his capabilities and desire to save people, but when you compare him to Goku... Superman has no technique like Goku does. Superman fights based on brute strength. Goku could simply dodge with ease, but people will still disagree and say Superman is faster than Goku because Superman is "faster than a speeding bullet" or "faster than the speed of sound." Now if you compare Goku's powers to Superman's powers, Goku has the upper hand. Goku has the upper hand in pretty much everything when it comes to fighting, not to mention Goku can also undergo numerous Super Saiyan transformations that make him several times stronger, speed and strength wise. But of course everyone already knows that, but they never put it into account against Superman. I have a ton of respect for Superman. He is one of my favorite superheros of all time, but Goku vs Superman? I'm sorry Superman, but Goku wins. Plus this battle won't go to the death unless Goku, Superman, or both are fighting each other based on a lie. So if they were to fight, it would be a friendly battle that goes on until one is incapable of fighting anymore. Either way, I see Goku coming out on top.
