Oh!! This is a super neat thread, thank you so much!!
This here is my Dark Souls inspired boss OC, Sosthène! He once was a hero who fell to the Darkness and was revived as an undead champion for her, and is torn between knowing he was meant to fight against it, and also his newfound loyalty placed in him by her. His memories are really fragmented too, so he only remembers bits and pieces of who he once was. He's just a very tired, confused, cynical old man who wants to sleep :') His concept was on the idea of like a new DS game rather then existing in one of the existing games.
I have a Bloodborne character I need to draw and add to toyhou.se, but her name is Blanche and she's a former noble-born who's just... A bit feral. Don't mind the fact she's mildly addicted to beast blood pellets and is slowly losing her sense of self and becoming a beast bit by bit, she's still friendly! She has a hunter girlfriend named Jess who's more magic based and less feral and tries to keep Blanche from fully succumbing to the beast side of her (and tries to withhold the beast blood pellets from her) (Blanche is my current Bloodborne character, and Jess is my friend's character since we're doing a co-op run!)
Lastly I have my D&D Vampire Monster Hunter Gunslinger, Valindra. She's not truly a Bloodborne OC, but she was HEAVILY inspired by Bloodborne, I originally made her before I even had the game, despite being highkey obsessed with it, and I even re-made her in the game once I had it! Her entire concept was the idea of 'a beast hunting beasts', inspired by Bloodborne of course, so that's why she was a vampire monster hunter :p
