Wally West's Arguments are obviously quite fanboy-tastic.
He says the Same stuff that all the Superman fanboys say all the time. I wasn’t impressed.
Ok. lets look at this.
Training: Now I'm not sure exactly what kind of training Superman has had over the years but he's a reporter for the Planet. He has a life outside of being "Superman". Goku on the other hand doesn’t do anything other then train himself constantly. His life is to be more powerful. And he’s trained with various gods and its stronger then any of the gods in his universe, a lot stronger.
Strength: In all out brute power. I'll give this to Superman. Now Goku is strong enough to hurt Superman hand to hand, but there is no doubt in terms of physical strength, Superman is stronger.
Speed: This one goes to Goku, hands down. Superman has amazing speed. But Goku can literally teleport (Instant Transmission) at will and his regular speed has never been clocked. But its so fast that it seems as if he’s teleporting anyways. While Superman is fast he cannot move instantly anywhere he wants.
Powers: Superman has a lot of cool powers. Heat Vision, Freeze breath etc. His heat vision is damn hot. But it can’t destroy planets. Nor would he ever be able to hit Goku with it anyways (see above). Now, Goku has so much ki power that he posses the ability to destroy a planet roughly 333 times during the Frieza saga BEFORE he became a Super Saiyan according to the powerlevels given by Akira Toriyama. How do I know this? Math. Simple Math. In the Saiyan saga Vegeta destroys the planet Arlia with absolutely no difficulty. (He used 2 fingers and didn’t even flinch) Then later while fighting Goku (after getting pummeled by Goku’s Kaio Ken) He threatens to destroy the Earth. He says something along the lines of “Dodge this next attack if you can Kakarot, but even if you do this entire planet is going up in smoke!” This is when Goku and Vegeta have the big ki blast battle where Goku uses Kaio-Ken x4. Now Vegeta’s Powerlevel at this time is about 18,000. So at the very least we know that with a powerlevel of 18,000 you are strong enough to destroy a planet. Now, Goku’s powerlevel using Kaio-Ken x20 while fighting Frieza on Namek is about 6,000,000.
6,000,000 divided by 18,000 is 333.333.
As note Super Saiyan Goku on Namek, with no training as a Super Saiyan (A new Super Saiyan) has a powerlevel of about 15,000,000. That equates to being able to destroy a planet roughly 833 times over. Now imagine Goku’s power during the Buu saga. Its easily 3-5 times more then what it was on Namek. And that’s likely underestimating it. (Unfortunately we have no way to really know as Toriyama stopped doing powerlevels after Namek) But its safe to say that Super Saiyan 2 is double the power of a Super Saiyan and then Super Saiyan 3 is at least triple the power of a regular Super Saiyan (though I think its more logical to assume that its double the power of a Super Saiyan 2)
At any Rate Superman posses no where near this kind of power. If Goku felt like it, potentially he could generate a kamehameha that had the power to destroy a planet easily over a few thousand times during the Buu saga. Superman cant compete with power like that.
Oh and as a side note, the “Taking time to power up” argument for Supes isn’t gonna cut it. Goku could Instant Transmission somewhere (where ever he felt like) Transform, charge up a kamehameha wave with enough force to destroy the Earth a few hundred times, Instant Transmission right back in front of Superman and kill him. (or at least really really hurt him.)
Now I give Superman a lot of respect. And I’ll admit that if Goku wanted to have a one on one fight with Supes, and he slipped up and Supes actually got a few good hits in. Goku would be hurting, a lot. But Goku is too fast, and his power is so absurd that there’s just no way that Superman could do anything about it if Goku felt like destroying him.
