wouldn't it be nice to be an evergreen?
Oh my god that’s amazing thank you"Mercenary Persona" is your power. Somewhere in your body is a slot through which cash (coins or bills both work) can be inserted. If a sufficient amount (determined by the ability, though you always have a vague sense of what it is for any given request) is inserted here and you consent to it, your body is taken over by an alternate personality designed to perfectly fulfill a request you were paid for. This must be a singular request that does not bring you any direct harm you didn't agree to and could be expected/predicted (so direct harm that is a result of an accident or for instance of an emotional need or vulnerability you weren't aware of is not filtered by this),. The alternate personality has not only different personality traits, quirks and preferences, but they even have a set of vague memories (vague enough to not cause dissonance, but still feeling like their own history while they are in control) and their own talents/skills specialized for the request. These skills are not supernatural, but they are among the top in whatever country you happen to be in. Talents or skills that would require substantial changes to your body cannot be achieved through the Mercenary Persona, though those that would require smaller, less visible changes still can.
