I have an idea!
Monster / Myth DNA: Leviathan PICTURE (i'm not sorry you can't make me sorry)
Secondary DNA: White-backed ratel; Mellivora capensis leuconota.
Info on honey badgers in a general sense, and a description of the white-backed ratel is on that page (but i couldn't find a picture of one :c)
Traits: LEVIATHAN: Sharp a** teeth, kind of like a shark. Long/tall, maybe over-long limbs/neck. Wings.
HONEY BADGER: capable of digesting just about anything, white stripe in hair, high pain tolerance.
What would he be like? He likes fire; the leviathan is described as breathing fire and exuding light from his eyelids and as such, regardless of whether or not Valentius is capable of doing so on his own, he has an obsession with flames. He'd always carry a lighter around with him and is frequently very taken with the flames, watching them flicker; some men may want to watch the world burn but Valen wants to make it.
He's very, very proud and pompous; the leviathan is described as the "king over all that are proud," and Valen definitely feels that he is superior to others in every way ("Nothing on earth is his equal" ). He's also fearless (again partially because of his leviathan DNA) and takes a very dim view of others trying to threaten him. He is aggressive as all hell, frequently snarling, posturing, and showing his razor sharp fangs, even to people who have done nothing to him.
A rather solitary creature, Valen prefers to spend his time eating and sleeping and is not particularly picky about either of those things. Anything that looks remotely edible will go into Valen's mouth and it's unlikely that, once it goes in, it'll ever come out. One of the very few times that Valen tries his best to be socially acceptable is when he's interested in having sex; he will try to court whoever is unlucky enough to attract his interest and fascination, except his idea of courtship is likely something like bringing kills or food to his object of affection in hopes that they'd find him suitable enough.
i'm not sorry
