I did get an idea off of your 'Lust' character, tell me what you think.
Name: 'Copperhead'
Age: Physically Mid-20's, Chronologically almost 2,000
Race: Annunaki (Sumerian Snake Demon)
Sex: Male
Hobbies: Motorcycle maintenance, drinking, cage fighting
Job: Smuggler/Assassin
Appearence: Despite being a snake demon almost 2,000 years old, 'Copperhead' has dived head first into the biker lifestyle. In many ways seems to be a vampire with a tan but his fangs are one position closer to the front then a vampire's and when agitated his eyes become snake-like. While in combat scales begin to appear on his skin as well. On a sidenote, when 'Copperhead' feeds it isn't some tidy drinking of some blood but the rapid consuming of a large amount of raw meat. At least the equivalent amount of meat as what's on an adult human being.
Bio: Born sometime after the fall of the Sumerians and the fall of the Roman empire, 'Copperhead' would gain a reputation as a rather straight forward being- for an Annunaki. Showing more promise in physical violence then most of his kind, it's probably one reason why he survived as long as he has. The predissecors to Vampires, the Annunaki eventually fell from power due to the complex magical process it takes to create another Annunaki- so complicated that it rarely succeeds more often then once a century.
Taken an almost zen approach to the loss of power of the Annunaki, 'Copperhead' satisfies his personal wants and desires as a biker/smuggler/assassin/drifter. Tough as nails, sneakier then hell from almost 2,000 years of experience, absolutely ruthless, immune to vampire bites, and able to deliver a supernaturally powerful venom of his own through his own bite- 'Copperhead' currently has a reputation among the supernatural criminial underworld as one who is not to be fucked with, but willing to get the job done for the right price.
His latest job has taken him to the preformance of a certain vampire stripper known as 'Lust' where his client is convinced she has in her possesion a briefcase full of incriminiating photographs, a breifcase 'Copperhead' has been sent to retrieve at any cost. Whether or not she actually has this breifcase is irrelevent to 'Copperhead', as long as whatever happens satisfies the client- no matter what happens to Lust in the process.
