Design A Mad Scientist Contest Chance to win a PMHi-hi guys~ Sorry the skin isn't as pretty but ugh -w- .... 
So I've been trying to come up with a new character for Strangers who is kind of a secret admirer/rival of Siren. But I'm having so much trouble coming up with a design. I don't have a full backstory for him however I do have some requirements for him. 
Here are the design things to keep in mind:
This is kind of weird but I would like him to be scary, yet handsome. 
He's in his 20's
He doesn't have a name yet, but I'm thinking Dr. Silico. First name is Xerxes.
He has to wear a open labcoat.
It's a male
He wears a tie OR bowtie
He's a Thanatologist (Studies Death)
Personality:
-Very Smart
-Devilish
-Curious
-Sore Loser
-Teasing (Way of flirting with Siren)
-Tsundere-ish to Siren (Pokes fun at her, she pokes back, but deep down loves her)
-Narcissistic 
-Competitive 
-Protective
What I have for he's backsto
