So this new character is the sadist type that likes watching "lesser men" writhe while he flexes is superiority.
He'll likely become a shitty antagonist and constantly try to one-up, or even NTR, the protagonist because he's about to get hard schooled in a lesson about humility.
Or, the lesser option- as it is more rare, he'll become so fixated on the hero that he'll eventually realize he's super gay for him. Which may be the case, as this guy screams "trap".
