This CP is another 2 Part idea with CP 76 being the second half of it.
My shorthand idea/title for this one is ‘The Bartender’ and is similar to CP 59 ‘The Baker’.
But for this one I don’t see the bartender being an assassin but rather a serial killer or maybe a kidnapper. Still a villain for sure but with enough substance to not make him a one dimensional or throw away jobber type character.
The 1st pic (dark and red drink) is his normal state. He works at a popular bar in town, not a, ‘standing room’ only type place but one where there’s always a customer and no time to be bored.
The 2nd pic (long-sleeves and green drink) is his other job. He works at a very upscale fancy bar/restaurant maybe. The kind of place businessmen, CEOs, politicians go out to.
I’d go as far to say as he even has two separate identities for each location. The average person wouldn’t suspect that he’s the same person. Maybe a co-worker would once they started talking to him for a minute but not from a quick glance or from a distance sort of thing.
He has tattoos but I like the idea of those even being fake and are ones he just puts on for show. He’s had to move across America a lot and needs to be able to shed his identity, kind like a snake with its skin.
I could see him being a big enough threat that the FBI are looking for him, but no one would suspect him being a bartender. That would stay hidden/secret.
Another possible idea if I didn’t want to go the serial killer route with him, is making him an information broker/gather instead. Between working both types of bars, he’s able to hear lots of potentially useful stuff for the right buyer.
I might even do a combination of both these ideas, as maybe selling intelligence is how he funds his lifestyle and helps him stay ahead of the law as a serial killer.
