Isn't this a stomp then ?
That's what I've been driving toward.
-
Overall Strength: Goku is
3.69x stronger. If he uses Kaioken x2, he doubles that to
7.395x stronger alongside doubling his speed. Goku could just bully his way to victory on that alone.
-
Heat Vision: Overpowered by stronger ki blasts, blocked by a more durable ki barrier or dispersed with kiai. Plus Goku has resistance to heat on top of his durability, so even if it connects, Heat Vision is going to take awhile to even do anything.
-
Freeze Breath: See Heat Vision.
-
Grappling: Sure Supes has way stronger LS but Goku can still counter with ki attacks to deal damage or use a kiai to get Superman off of him. Not too mention Goku is the better fighter, making getting Goku into grapples harder because he can fight around that and even if Superman succeeds, Goku's just blast him off.
-
Brawling: Goku is the way better fighter by several orders of magnitude.
-
Range: Goku can effectively fight within and outside of Supes' range. Plus he has IT, allowing him to close any gap at any time he wants. Hence, Goku dictates the terms of engagement.
-
Intelligence: Supes may be smarter overall but Goku beats him as a combat expert with way more experience. Superman's intelligence doesn't actually help him here.
-
Tl;dr...Goku beats Superman at almost everything and has effective strategies or powers that allow him to completely counter the one thing Superman has over him. Goku is able to completely control the nature of the fight and can really win at any time he wants. It's not a question if Goku wins, it's how long will it actually take.
