Shadow Slave: Prince of Darkness

I have been thinking... what type of character should i add, because this character is going to be a evil psychopath and also in future he/she may become Raizel Best friend or girlfriend.

So i need some ideas from your side, like the what should be the name of the character and the aspect i should give him/her.

But remember one thing that this man/women is going to be the evil of the evil character.

( Also the new chapter is coming soon )
