TLDR.
Anyway Superman punches Goku and he gets ******* disintegrated. GG
Ok its not simply GG, but I do want to point out that Superman just outhaxes Goku in so many ways that its not even funny, even if we were to highball it and say Goku is superior in AP.
Goku fires an energy blast? Superman can absorb not only solar energy, but also electricity and even
magic, so Ki shouldn't be impossible for him to absorb. Even if it isn't something he can absorb Superman can always become intangible to dodge his attacks, and we know Goku's can't hit non-physical beings due to the contrast shown between regular ki attacks and Hakai, which is highly specialized to the God's of destruction (Beerus can erase ghosts, but Goku can't).
Superman also has a lot of skills that he can use to his advantage, be it potential wincons such as his Super Hypnosis and Deconstruction, or stuff that gives him edges in a fight via distractions, such as his Super-Ventriloquism (to create sounds to distract Goku) or Shapeshifting (to trick Goku). The only two things that probably wouldnt work are ironically his heat vision and Freeze Breath, though I do think the latter could potentially still freeze him in ice (even if it cant hurt him).
Finally, the last thing to consider are their intelligence and characters.
Goku is ... generally dumb, and even though he is a genius when it comes to fighting, he is someone who fights very directly with the expectation that his opponents will fight equally, and generally struggles with more trickier opponents as stated by Roshi in the TOP.
In contrast, despite his lackluster appearance, Superman is a genius who's intellect surpasses that of supercomputers, and while he's likely inferior in his skill in martial arts, he more than makes up for it with his aformentioned intellect and the fact that he's very experienced with his own powerset. In addition, Superman generally fights with the purpose of stopping his opponents by any means necassary (barring killing) and with whatever abilities he can use, so he would likely do the same thing here and not fight on Goku's terms and rather his own, meaning he would be a more trickier fighter in this matchup (which as we said before, is something Goku generally struggles with).
Lastly in terms of overall stamina, while Superman may not have the unending stamina of his Post-Crisis counterpart, his ability to constantly absorb solar radiation means that in a fight of endurance, Goku would run out of Ki faster that Superman could be drained of solar energy.
All this being said, Superman's greater hax, superior intelligence, greater smarts and superior stamina means that even with Goku's superior AP, the saiyan from Earth is left fumbling in the dark by the Kryptonian from earth's might
and mind.
That being said, Superman wins by using his newfound power of SUPER COOKING to distract Goku with a feast.
And yes SUPER-COOKING is totally definetely real and im not making this up, see?
Also:
His speed and power multiplies by 50x in just Super Saiyan 1 and over 500x in Super Saiyan 2. Superman is seemingly only baseline 3 2-C on the VS Wiki.
The DC universe is also many times bigger than our universe or the Dragon Ball one and Goku's God Base scales from a feat that puts him at an inferior level, even with multiplies. Also the super saiyan 2 and 3 transformations shouldn't be factored in because:
- They aren't included in his ROF key
- They have been effectively replaced by Super Saiyan Blue, which is the God Ki that gave him his 2C rating combined with the Original Super Saiyan.
- It wouldn't make sense for Goku to use SSB is his battle against Golden Frieza if SS2 or SS3 granted a greater multiplier when he is in his new 2C base.
