Nephel
Originally a Castlevania OC, she's become a more general fantasy use. In her current lore (which evolved in part from a tabletop campaign I played her in), she's used to be a badass evil sorceress who was defeated by a typical heroic fantasy party but due to the efforts of a particuarly devout follower, was in part preserved and able to be resurrected ages later. Unfortunately, there wasn't much left of her original body so she was brought back as a humble ten year old...but she doesn't know the humble part. She's a blast to play, but while she's entirely reformed from her villainous ways, she's been described as cross between Hilda from A Link Between Worlds and Angelica from Rugrats. I love her so much - this art is so old and I need to draw her an updated one.
Rayan
A Legend of Zelda OC - he's a Garo ninja from Ikana's bloodied history. I don't get much opportunity to play him, as Majora's Mask is complicated and just a little out of fashion in the Zelda community. I could theoretically make him a normal Sheikah or a Yiga if I wanted to play him more often, but I like him the way he is. He's very sweet underneath his little attitude problem, with a past (and complexes) befitting of a child soldier turned shadowy assassin. It's hard to imagine him outside of the RP concept I wrote him for - an AU of Termina with no Hero of Time. He'd have to join up with another character to save Termina but there are plenty of twists to their adventure since things are on such a different course now. He was flung forward in time from his original era. But I have used a modern day expy of him in some tabletop campaigns. Isn't he cute? My friend said he looks like a Naruto OC, which I found hilarious.
Nadeshiko
Another Legend of Zelda OC. Well, that was the idea anyway. She was originally supposed to be a Garo, too, but I didn't end up needing her for the above concept. She was meant to be a relative of Rayan, or at least a lifelong aquaintance. NOT ship material either way, they see each other as family and she's a lesbian. Still, she's so beautiful (my art doesn't do her justice but I think it gets the idea across) that I couldn't abandon the full concept of her character entirely. I've played versions of her in tabletop campaigns. In the current one she's essentially a Jedi, which is a ton of fun. It suits her. My spacefaring vampire lesbian ninja. It's like she'd gunning for as many cool tropes and class changes as Zelda.
