J Jonah Jameson punched an unmasked Spider-Man bloody on his own, who beat Firelord unconscious, who has harmed and held his own against the Silver Surfer, who managed to fight the Griever at the End of All Things for several minutes, who almost killed the Molecule Man.

Miles massively upscales from all of this btw, he could destroy the entire Marvel omniverse, the Marvel outerverse, and infinite layers infinitely beyond this several times over
