@Killer_of_trolls: Lol, I don't know much about KK other than his fights with Superboy/Batman. Let's say it's when he fought Superboy then.
I think Hayato could still do this. I retract my earlier statement that the Superboy statement was PIS because I believe that Superboy wasn't attacking at full strength because let's be honest if he was flying at lightspeed he would probably cause serious landscape damage, if that makes any sense. Also he kind of just used Superboy's momentum against him and got him in a headlock for a little while, admitting he couldn't hold him for long. We also know that both Marvel and DC are very inconsistent with showings of their top tier characters.
Hayato has been shown to a master martial artist even when using 0.0001% of his power and not even concentrating on the fight. He can bend battleship cannons with ease and flip tanks over just as easily and can move so fast that even at 1/1000th of a second only a blur could be seen as he performed a low kick. That's some serious speed no matter how you look at it, rivalling even Dragonball speeds.
I think it would be a very good fight, definitely not a stomp for either.
