My go to is the Sociopath https://tvtropes.org/pmwiki/pmwiki.php/Main/TheSociopath A possibly villainous character (To go along with the main human villain of pretty much every Persona game since three). Could be mixed with an affinity for gun and ice moves if you go the cold emotionless type route or fire, like an arsonist or a mad bomber. That last part may or may not have been inspired by Wicked from Caligula Effect, a game not many people have heard of and less have beaten without just holding X during combat. Persona ideas to go along with this could be famous archers or gunmen (Hou Yi, Billy the Kid, Magoichi Saika) to fit the whole cold sniper archetype or mad people (Caligula Go figure, Ajax) for the mad arsonist route. I feel like over thought this one somehow.

How about Masochism? It could use mostly physical attacks, i.e. draining HP, and take the appearance of a sharply-dressed goblin with cuts and bruises all over.

Sopolisist (Extreme Egocentrism) https://en.m.wikipedia.org/wiki/Solipsism The belief that you can only confirm your own existence and everything /everyone else must come from you mind. Sopolisist believe that they are the only authority figures in the world and that the world really does spiral around them due to their confirmed realness. Affinities for this could be psych, bless, or curse. Personas that would likely fit this mental states could be famous leaders/heroes that were recognized as gods or set as the pinnacle of perfection. So like Galahad (Arthurian Legend), Baldur (Norse myth), Endiku (Mespotamian myth), Helen of Troy (Greek Myth), Aphrodite (Greek Myth), Bellona (Roman Myth), Julius Cesar (Roman), and Cleopatra (Egypt)

Darkness

Uncontrollable anger could be one Have the affinity be towards physical strength With strong attacks
