Need a Enemy for skeletons thread

I need a klaus like enemy for the skeletons Mature thread in the downtown section
I need a character that will be the focus of all the protagonists energy to destroy them

The protagonists are
Noah Zachariah - hunter one of the five
Xavier Lowell - Wiccan (Male witch)
Naya Summer - Female werewolf
Sergiy - Male werewolf (Can possibly flip and become an enemy)
Sophia blackwood (Female witch with a alternate personality so she can flip between good and bad)

I am very good at working with plots I just need an enemy doesn't matter what really vampire, witch, hybrid, werewolf we can work on an idea

It is a mature thread so there is sexual moments and explicit language so please keep an open mind.

I'm gonna be making a Original if the mods or admin approves. But I can include Alistair and my new character later in the rpg.

Yea Alistair is basically a good guy i don't mind multiple enemies like how all the originals are bad but i need one focal enemy
