I was inspired tonight to try to make a character in Dresden Files based on the Comic book (and not Movie) Kick-Ass.

Name: Dave "Kickass" Lizewski
Template: Pure Mortal
High Concept: Real World "Super Hero" Vigilante
Trouble: Constantly Getting in Over My Head and Beat to hell

Other Aspects:
Lonely Nerdy Comic Book Geek, Metal Plates and Nerve Damage, "I'm Kickass!", Hero for Hire!, Jealous of Red Mist's Fame

Skills
Great: Endurance
Good: Scholarship Weapons
Fair: Athletics Alertness Deceit
Average: Burglary, Presence, Stealth, Investigation

The problem I have run into is I don't really know how I should do a stunt for him. I wanted to give him a stunt that reflected his secret identity. As Kick-Ass, he would be feared/revered/hated/loved by members of the general populace that wouldn't know about him as "Dave".

I thought about breaking this up into multiple talents but I didn't know how many it should really be because "+1 or +2 to all Social interactions while in costume" seemed wildly overpowered compared to other stats but seemed to really fit what was going on.

I also though about perhaps using a special "Superhero Identity" Stunt which acted like "Beast Change" Where certain abilities only applies while in costume, but I didn't know what kind of bonus that it should have.

All in all I need ideas and suggestions!
