Oh man, I'm gonna have to dig deep for this one. I spent most of my early creative years writing half-assed novels, not drawing comics, so most of my terrible OCs exist mostly in prose form only (because I spent those years insisting on only drawing horses and non-humanized dragons).
Surprisingly, my very first OCs - created at age 7 - were surprisingly decent? They were a pair of trolls living in a cave together in some kind of best-buddies/platonic life partners kind of deal, and spent their time tootling around in the woods and raising orphaned wildlife and being nice.
BUT I went diggint through my old dA-archives and found this glorious beauty of a man (demon? thing?):
This is from a decade ago, and my memory of the story is super-hazy, but I'm fairly certain that this guy (I think his name was Kan?) had a story that went something like this: He was a half-demon (his father was some kind of arch-demon) and his human mom had died when he was a kid, and he wore that silly scarf over his face to hide some weird skin-condition that revealed he was a demon - like, the veins were clearly visible beneath his skin, and they were all swirly and black and weird-looking - and he had sharp teeth and everything. You can't see it in this picture, but he has really long hair. It's cut shorter around his face, but he had this really long braid at the nape of his neck.
.... I should probably add that despite the weird skin and the teeth he was, of course, really handsome. Because what's a terrible OC without stunning good looks? XD
He also barely spoke to people, and fell in love with a girl who had the power to change the world (like, literally change it at will; she could stop and restart events whenever she wanted, reliving moments with the knowledge of what happened next), but decided to not tell her because aaargh he was a demon and he couldn't expose her to that kind of danger, blah blah blah. Mostly he sat around brooding in proper half-demonic fashion and feeling sorry for himself, when he wasn't being the world's most kickass fighter. Because of course he was.
I cannot for the life of me remember the exact details of the romantic subplot, though I believe they got together anyway, and then there were some other characters who joined the adventure, and they all beat the crap out of his archdemon dad, and lived kinda-sorta happily ever after, I guess?
