An idea for a new horror based character for the Main RP(?)

Now I have an idea for the character for a horror based plot but also I'm trying to work on the plot from the aftermath of the battle between Viper's Group and BlogClan for Coldice but he had the spotlight for so long to the point where I'm going to give him a break plus he's currently recovering from injury.  The character will be a new villian with a horror based plot like I said before  so I need so suggestions for the story, apperance and such  and I would love to know what you think! :D
