My idea so far - let me know if you like it -

Scenario - The world knows that vampires exist. But as with anything else, the response to "I'm a vampire" can be met with the same reactions as "I'm a _____". Some people will be interested, some will be apathetic, others will be discriminatory. Some vampires will try to hide it.

My character - I'm a vampire, and I'm proud of it. I've been a vampire for the last 100 years. I enjoy my power, and the powers I can exude over normal mortals. I like knowing that I can be the person who will command. However, I usually don't use powers to supernaturally influence mortals. I mostly use my powers to avoid fighting with vampire haters/hunters.

My description - I do nothing to hide my pale skin. I am six feet tall. I am lean and muscular. I have green eyes, and short black hair. I always dress well, preferring to be in suits/tuxedos.
