It would have to be someone like him because he's a narcissist but also weaker than him so he can live out his domination fetish, because that's likely the only thing that really gets him off about sex. And someone who doesn't completely comply with what Vergil does on the surface but actually enjoys it regardless. Basically a V 2.0. Not that I want V to come back, he served his purpose (and I know someone is going to complain about this) but someone similar.
A character like this would have no reason to exist besides fujo bait though. The only viable reason I can think of, is if he helps Virgil bridge the gap between actually caring about something more than himself, but I think his truce with Dante will do that anyway.
