How can you say that Mugen Kugi punch won't do anything to him? I think you're ignoring the "MUGEN" part of the move.
It's a name. That doesn't mean anything.
There's attacks that always have the name unbeatable awesome punch, which only broke a wall. Now does that mean it can beat anyone? No.
Also, saying that Hulk can "one-shot 98% of DBZ" has me highly skeptical about your arguments, as well as other things but that's the most recent. How can he, for example, one-shot someone with planet-level durability?
I don't know if you know this. But Hulk has planet level durability. If you can one shot the Hulk you can do that to anyone in dbz.
