can Goku even damage Saitama?
so far no one was able to damage Saitama (Make him bleed)
Exactly, we're talking about a guy who didn't even scratch himself, and that's because he was receiving attacks (copied from himself), look at Saitama evolves
exponentially and infinitely, Goku is a limited being that depends on enhancers (transformations, his limit physique have already been established without enhancers), he is a guy who is portrayed as getting weaker during fights and having no resistance, while Saitama is the opposite, he gets stronger and his power is infinite, and this is so true that Goku loses, people believe that Goku's power is unlimited, but this is not true otherwise he would not lose as happened in the recent arc, he would not weaken, the opposite would be the case he would become stronger and stronger , he would not run out of energy (ki), he is a guy full of flaws who in most fights is helped and at the limit he manages to beat the villain of the arc while he is all exhausted, tired, without energy, he receives energy from others, he is killed, he is weaker etc...
The strength of Saitama evolves exponentially every second as previously stated, for example: 2,4,16. Let's assume that Goku's power at its maximum is 4000 and Saitama's power is also 4000. Additionally, let's assume that Saitama's power is exponentially increased every 1 second...
After 10 seconds, Saitama's power would be:
Final power=Initial power×210Final power=Initial power×2^10
Final power=4000×210Final power=4000×2^10
Final power=4000×1024Final power=4000×1024
Final power=4,096,000Final power=4,096,000
Goku's power after 10 seconds = 4000 (It is very likely that after 10 seconds Goku's Ki will weaken, as it is limited. LOL )
Saitama's power after 10 seconds: 4,096,000
Suppose current Saitama can lift 1000 planets with difficulty. After 1 second, the weight of the 1000 planets will be insignificant to him.
Saitama will kill Goku's trash with the first punch he throws, the most exaggeration of goku physically and using enhancer was when he punched Moro using the IS and the earth shook, wow that's nothing for Saitama, the guy in his strongest form is only capable of making the earth shake, holy shit.
This is the true level of Goku's punches, they are so strong that they are cause a small dent in a train, Saitama will really need to dodge this and look, when Goku threw that punch it was a saga coming back about being the strongest in the universe (excluding deities)
