One of my most fleshed out characters is a vampire called Noah Bates, which I created with a friend, Dr. Oru. He belongs to a story I call "Bloody Drugs" and his whole profile can be found here! I rarely draw him, even though he has a fully written personality, story, relationships and background. Imagine that!
Anyway, Noah is a vampire who sparkles under the sun (like Twilight, you guessed right. He partially exists to mock it) and has the power of body transfiguration which he uses to grow massive tits. Noah is a veterinarian and uses crocs unironically. He also has a boyfriend of sorts called Acanthus who can shape-shift into a wolf - and I've actually drawn Acanthus because his wolf form is cool; Acanthus belongs to Dr. Oru and his profile can be found on their website.
So yeah, another of my billion characters yay!
