Pavel has seen a lot in his (relatively) short life. Sure, he's been around 80 years but he was turned at 30 and that has opened doors for him that any normal octogenarian wouldn't pass through.
Pavel grew up during the height of the arms race between the USA and the USSR. The fact that he made it to the States at all was a miracle but that could have something to do with the fact that he was turned before he traveled, and don't even get him started about the difficulty he had clearing customs as a dead guy! There was that whole re-routing issue....
He might be an upper level demon but that doesn't mean that he doesn't have family values. His family is his life. He would ruin
anyone who tried to mess with them. His aunt Olga is the queen of their vampire brood, [FAMILY STUFF HERE]
Since Vampires were banned from the underworld they've had to be a bit more resourceful as a species. Pavel lives in fairly modern quarters and has had special UV blocking windows installed in his home with a backup automatic shutter system if a window is broken. Nonetheless, he never sleeps unless it's in his hidden windowless room, after all a sun-shined vampire is a dead vampire!
Pavel has all the typical vamp powers: Agility, Clinging, Shapeshifting into a wolf (as well as a bat), telekinesis, Super Strength, Power Granting (if creating another vampire), Enhanced Senses, Life Link, Immortality, and Immunity (to certain witchy powers). Of course none of these powers ensure his survival if he isn't careful and if his family isn't safe.
Pavel isn't mean but he isn't kind either. He doesn't like humans very much, is very opposed to witches, and doesn't really like other demons. I guess you could say he is happy among bats of the same wing. Too corny? Pavel could probably use a friend or two but you'll have to warm him up first.
Pavel is gay and has always been open about it. He's a vampire, he will take you down if you have a problem with his sexuality. But who would, he's a fierce attractive bad-boy, aren't you happy just looking at him? He is more of a flirt than anything, he will flirt with everyone and enthral any and all to get what he wants. He has had 4 serious relationships during his 80 years and he isn't looking for another right now, but the right person could change his mind.
The Source, Demons who would cause trouble for his family, and most witches are all on the enemy list. Honestly, he is a suspicious one, even other vampires aren't easily trusted.
