Comic Butcher may cross the line in the MHA universe faster than the speed of light and he definitely would hate the Hero Society… are not bigger fishes to kill? All for One is pretty much Homelander without the pretense (and actually intelligent and with way more varied power collection) and the Paranormal Liberation Front are a legion of superpowered people not wanting to have checks and balances.

Midoriya is also the closest thing to Hughie, specially because he was born powerless.
