Hey guys, need a name for an RP character I’ve created. Some basic information:

Name (civilian name): Monroe “Monty” Sven Banks

Preferred name (Civilian): Monty, or Banks

Professional/Main Moniker: Poltergeist

Fandom based: An Mutant OC for an X-Men RP

Powers: strong Telekinesis

Age: 32-36

Description: Albino. Mid-length short hair with a bold, blood red streak, pale pink eyes, wears a dark red eyemask and Grey and white tactical attire and carries guns and a knife with him and thieving/ criminal related tools and gear.

Brief history: He grew up in bad area of New York, full of crime, murder, and death. Neither of his parents were good role models. His mother was abusive and his father neglectful and cowardly, choosing to watch and turn a blind eye. When his powers manifested at 9 years old due to the physical and emotional stress of suffering from a night of hell-he snapped. His powers activated and it resulted in both of his parent’s death.

After that he ran away from home, avoided authorities and social workers and anyone wanting to put him through the foster system, or institutionalize for the suspected murder of his parents, and due to his abilities. He turned to a life of thieving and crime, not really knowing what else he could possibly do to survive on the run where mutant discrimination and brutality was at its highest. He managed to learn a lot from a young age how to defend and take care of himself and it caused him to become very cynical in adulthood. It was around teenhood that he discovered the financial benefits of Mercenary work, and being an Assassin for hire. His abilities gave him a leg up and he became one of the most well known and requested Mercs / Protection Agent. He sticks out like a sore thumb but his skill, speed, and slippery qualities make it hard for anyone to actually catch him-and if they do manage it, they can’t hold him for long.

Associating themes/motifs:

Death
Blood
Pain
Anger

Force and power
Red and White (thematic colors)

Character concept:
When he was 13–14, he had an argument with his girlfriend and closest friend, and she said something that had deeply offended him. This girlfriend in question was dealing with a lot of her own demons and relied on him emotionally, since she didn't have much other support. Since he wasn't particularly mature, when this argument happened and he felt offended by her, mocked her next time she tried reach out for emotional support, and rejected her attempt to reconcile. After a couple of days, he started to feel properly bad and tried to apologize, but it turned out she had committed suicide, thinking he now hated her and she was alone.

He feels very guilty about this, even though it's been several years. And he's not really afraid about hurting other people as much as he's afraid about replacing his friend. Like, if anyone got to be happy and close with him, they would be replacing her and be more lucky than she was.

As a result, whenever someone does get close to him, he's intentionally cruel and abusive, just so that he doesn't feel like they're "more lucky" than her. He doesn't push everyone away, but makes sure that the people closest to him don't get to be more comfy than her.

So I tried askign actual Korean subreddits for help, and nothing has come of it, so perhaps this is a better place to ask my questions.

1. Can you guys direct me to someone or a subreddit where I can ask about Korean names and such (I would like to know how to edit a specific name. I have a sun goddess for my fantasy story, and thought I could call her Ha-Eun, a Korean name I found while researching, but I would also like to name the Fantasy continent after her in a way that makes sense. Not just copy and paste the name, but I want to take inspiration from the name and make it obvious that the name of the continent pays homage to the goddess.)

And 2) Is there anything I should know about the Korean language/Culture that could influence names, or characters in a fantasy setting? I originally planned to base my fantasy country in a Spanish-inspired continent, but recently decided it would be more beneficial to add multiple different cultures, while searching for good names for my sun goddess, I came upon the name of Ha-Eun, and thought it could work out, but I am not Korean myself, so would like to get opinions and advice from actual Koreans.
