Okay here we go

Name: Aiden LeBlanc
Age: Well, he looks like he's in his early 20s... In actuality he is a couple hundred years old. Vampires don't really need to keep count.
Gender: Male
Sexuality: Bi
Species: Vampire
Powers: Enhanced speed and strength, can only be killed by either a stake through the heart or decapitation.
Personality: Aiden is... A piece of work, to say the least. He seems to be in an almost perpetual state of anger, for unknown reasons. He can snap within seconds and has an explosive and violent temper. When he isn't angry he tends to be in a bad mood and is consistently moping. If you get to know him and he actually likes you he is a complete grump, though at times he can be sweet.
Appearance: Media. A solid 6' foot with fair muscles. He has long, sharp canine teeth like many vampires. He wears clothing you'd expect of a prince to wear, and a sword nearly always dangles from his belt.
Skills: He's a pretty good fighter, especially with a sword, and an accomplished horseback rider. He is smart and a quick thinker. He can pick up small details easily and has an almost photographic memory.
Flaws: Again, he has a horrible anger and a quick temper, which also can make him stupid. Although he has enhanced speed he mainly relies on his strength when fighting, so he's weak in that area.
Backstory: Aiden grew up in a castle, like just about every prince that ever existed. Everyone in his family was like him, a vampire. Most of the nobles in the castle were, in fact, even some of the servants. They were born like that and will probably die like that. Unfortunately, vampire monarchies are weird. They can take hundreds of years to die naturally, which can be a problem. Aiden was the eldest brother of three, meaning that when his dad eventually died he'd take over... He was always a problem child, and he disobeyed his parents a lot. He didn't pay attention to lessons, he got into fights and ran away to the forest. After a while his father got sick of it... And disinherited him. Not formally, he still lives in the castle and is considered part of the family... But he is no longer a contender for the throne. This honestly didn't help his temper, so now he just mopes around in anger.

You can make your character and we can figure out a scenario! If you want me to change anything just say so ^-^
