What is your OC's lore? Mine is sordid.
Kenshin's lore:
Kenshin is a bull, born on Nov 23'rd 1998
He was used as a Genua Pig by a Japanese cult leading pharmaceuticals and tech "Foxis." Their motto is, "Bridging the gap between worlds." Using his pain, they discovered new entities to attempt to take over the world. It went horribly as the entities shared his pains, sympathized with, and protected him.
Kenshin's mother, Yuki Kenshin or what she's now called "Mothers Regret" can grind people by dragging them in a physical object. Laughing as a sadist as she does.
She does this by phasing through doors with occult magic and supplies the magic through her own hatred.
An angry mother trying to protect her son, but she blindly kills anyone near him even those who help.
She was killed in front of him at age 4 to get the most emotional pain out of him, he still remembers it vividly [acid bucket trap he accidentally activated] and blames himself.
His trauma runs deep.
