Actually Goku has something called, Martial Arts. He can read all of SupermaanÃ¨s movements and sense where he is, as far as beyond the solar system. Goku will never resort to any cheap tactics. He has Superman beat. Though would be interesting, because nothing can cut superman in half or shoot a hole through him, that way it would be interesting to see how Goku will defeat him.
They both come from blown up planets as babyies, they grew up in different parts of the world. They both have that sense of justice and would never have such things to fight against eachother, other than the martial arts tournament, but superman will neevr join that because he doesnÃ¨t want to hurt anyone. Though if Goku urged him to, because Goku loves to fight and test his abilities against other warriors. Superman might be tempted. And of course Goku will know who he is off the bat, no matter if heÃ¨s Clark Kent, Goku can sense anyone.
But in the snese of their strengths, Goku was able to kill foes who were strong enough to blow up planets. And Goku does have speed, and if he needs it, Instant Transmission(forget what Japanese or oringial name for that was). Superman has heat vision, xray vision, flying ability.
Would be awesome to see the match up. They won;t kill eachother because there will never be a reason too. but would be interesting to see a fight to test eachother.
