The secret town of South Park: What Is He?(tweekxcraig)

South Park is not a normal town, no it is as far from normal as you could possibly imagine. A century ago South Park was hit with a toxic gas, this gas was thought to have completely whipped out the quiet mountain town however it didn't.
South Park was soon forgotten but the same citizens that were hit are still there.
The so called toxic gas did change south park as it gave all people abilities, powers or in some cases magic. No one knows fully what the gas was but it was supernatural. The town is now secret and unknown.
There was a rare minority who didn't get a "normal" change as they became monsters or freaks. A vampire for example would fall into that category.

Craig tucker is far from ordinary well this whole town is far from ordinary.
Craig is one of the minorities of vampires who still make haven in South Park he is the only full vampire in his school and so the only one who feeds on human blood and the only one people fear.
There is another difference between him and his so called 'friends' but he's not planning on telling anyone besides he has a million lifetimes to worry about it so why say anything now?
Everything seems like it will remain as it is until a mysterious boy shows up but the question on everyone's mind is, what's for dinner?
No that's just Cartman.
The question on everyone else's mind is:
What is he?

*under minor editing it's not going to affect the story line at all tho*
