They both live in a dark world full of unheroic superheroes.

They are both public-faced superheroes working for a corrupt organization (Vought and Hero Clan)

These organizations cover up their murders and those of other heroes to have a good public image.

Both are known to be selfish and sadistic psychopaths.

Both only maintain their facade of a perfect superhero in front of the media, but in reality they are mass murderers, and they blame the villains for their failures.

They both don't give a shit about committing mass murder either.

Both are targeted by a group of criminals, both groups have someone who had close people who were killed by another hero (Billy Butcher and Ihwa).
