I will copy and paste something if you allow 'cause I don't have the time to write it again
*From another board:
Well, Goku can multiply his PowerLevel each Time he goes one step in the SSJ ladder. BUT if his Power Level is 5000 and he goes SSJ4 and his Power Level increases to 500.000.000 wouldn't mean his Strength, Stamina and Speed increase by too by a factor of 10.000.000. He becomes , faster, stronger but by an much smaller amount. If he can carry 40 tons in his normal form he would be able to carry something like 80 in SSJ4, the same goes for the spead, the bonus is small. You should first read what the power level shows before making such bold statements. The Power Level shows the energy a being can bring up to a fight. The smallest amount of the Power Level shows strength, speed, stamina or fighting skills. It's all about Ki, the energy you have to make such moves as kamehameha. Most Moves have also an upper limit of energy you can put into it. Of course you can use that energy to boos strength and speed, but only an small part of it, most goes for the "energy" Fighting. If you have a high Powerlevel your attacks can destroy a planet, but hardly more, since you can't put all you energy in one hit, you need still energy to move to fly etc, you get the point i guess. So with a high Powerlevel you can fight longer with stronger attacks, nothing more nothing less, you are still not able to move a planet, just to blow one away, you are still not able to fly faster then speed of light, but you move at a higher speed, you still get hurt when you get hit by a blow, remember, the attack Piccolo used to kill Raddiz, it would also kill Goku SSJ 1000000 if he wouldn't dogde or "parry" it. The feats of strength, speed and endurance seen in the DBZ Manga and Anime prove my point and it makes perfect sense, why beacause it was explained in the Anime^^. But don't worry Goku will still be able to beat superman.
He may not stand a chance against Superman-Prime, Pre-Crisis Superman, All-Star-Superman even at SSJ 1000 should he ever reach it (unlikly since the Series ended years ago, I know it since 1991, best friend comes from asia and it is his most fav. he traslated it to me, till i saw and read it myself when it was released here because they are so insanly powerful that it is just stupid. Superman-Prime doesn't exist anyway, he will, but this will take some years *g*, Pre-Crisis Superman doesn't exist anymore because his powers were so incredible powerful and stupid that DC had to start a crisis to wipe him, and his boring comics, from the unvierse. All-Star Superman isn't canon so he won't count. Soo this leaves the current Comic and Cartoon Superman^^. Well well here we go.
Comic Superman may be stronger, faster and invulnerable, but hi Johny Byrne Incarnation would only beat Goku till SSJ3 at four he would loose, barley but still. The current "evolution" of Superman would beat a Goku till SSJ10 then it would be a draw.
But the comics are getting more boring the stronger he gets, so this is hardly an etertaining fight^^.
So what about the Cartoon Superman, he is after all the most entertaining one, and as such the only one Goku should fight. Lets see, strong, fast, nice heat vision, but well, after all i saw from him i would say he can fight Goku to a draw till SSJ1, at SSJ2+ he wouldn't stand a chance. And don't say i have to pic the Comic Superman for the fight, because we talk about the Anime Goku and only Animes Count and this is the animated version of Superman, so Goku wins .
Goku, can support half a city and bring it into it's proper place. Struggles with a building. Upper limit DB GT Str feat SSJ4.
Superman, I guess everyone here knows about "S" ridiculous Str feats.
Goku, people think he moves at the speed of light, just because they can't see him move. However, they forget how limited the human vision is, so his speed feats show he isn't that fast. When his friends are in danger, ir get killed, he still needs some minutes or even hours to reach the battlefield, even in such an emergency and hurry. Goku is most probably beyond the speed of sound and way below the speed of light.
Superman, Speed of light and beyond.
Goku can charge himself with enough energy to resist a sword edge, he still gets hurt by physical hits, of enemies who are fast enough to hit him, even his wife chichi . Energyattacks can kill him too, even at SSJ4. Golden Uzaro (the big Golden ape that Goku or Vegeta can turn into) is physically much much stronger then a SSJ4 Goku (which prooves pretty much the point with the power level, since Golden Uzaru has a lower power level then a SSJ4) and could kil Goku with his bare hands, but he isn't as fast .
Superman resisted Galaxydestroying blasts, nuclear weapons and much much more.
Goku mastered all the martial arts there are in the DB Universe.
Superman is far away from such a martial arts feat. Batman yes, "S" NO!
So, Goku can't fight Superman physically, it wouldn't harm big "S" enough, he isn't fast enough to turn this into a victory. BUT Superman never hit's his enemies with ful STR (he never kills), he only fights at Superspeed if he has to (against Imperiex Probe for ex.). Goku is dumb as an Monkey, he would never figure out what Kryptonite is, it's most likely for him to eat this s*hit.
The most powerful attack of each DB (Kamehameha or Genki-Dama) char isn't strong enough to kill Superman, who survived an direct "energy" blast from Imperiex himself, the Destroyer of Galaxies. BUT it might hurt....
So, Goku would need all his friends to go toe to toe against Superman. Even at a SSJ100 (Gogeta or Vegeto too) he would still be, physically, weaker and slower then Superman and not nearly as invulnerable. But his Energybased attacks would give "S" a hard tme .
The DB fans logic is really messed up, they misinterprete Power with physical attributes. You can see that his Kamehameha gets stronger with each power level, he can destroy a planet with it, but even at his peak (SSJ4) he wasn't strong enough to move a planet, just half a city, and even that only barly. IF his Str would increase in the same manner as his Energy he would throw his enemies from planet to planet, crushing them between moons, and he wouldn't even need to breath since he would be soooo fast that he wouldn't have to leave the atmosphere for longer then a sec.
So don't come with "he said this and that" or if you multiply his str by x5000, watch the show, see how he struggles with "in truth not even half a city, just an sector" or how long he needs to save his friends, even when he flies as fast as he can. Watch an Golden Uzaru who is much stronger then a SSJ4 even though he has an lower powerlevel. And realise that the powerlevel shows mostly the "energylevel" of a fighter, nothing more nothing less.
From the another board:
Gokus penis is 9 centimeters long, well increase in Power x500 SSJ4, WOW his penis is now 4500 centimeters long, that must be destiny caue this theory "SUCKS" XD.
The only one who can beat Superman is Batman, get over it. And hell yes he is an better martial arts expert then Goku.*
SO Goku would be weaker and not as durable as the Hulk. However Goku would have an speed advantage and his powerful Ki attacks, though the Hulk survived some kind of energyattacks before, it would give him a hard time. But I think that in the end the regenerative powers and his durability would be enough to allow the Hulk one hit on Goku, and one hit is enough for an pi*ssed off Hulk who tried half an hour to hit an annoying, stinging, Fly
