Can't wait to see your idea for a female Lust! I actually submitted an idea for a male Lust. 

After discussing with Phantom, I love the idea of how he conceptualized Wrath and I don't mind giving it a shot if I can't be Lust.

Wrath is a kid who had been drugged most his life because his parents believed that he needed to calm down. Unknown to them the drug was highly toxic. The years of over medication took a toll on his body leaving him an angry and resentful husk of his former self. Something he considered sub-human. Very little is required to set him off. Do not underestimate this poker-faced middle school punk. His powers allows him to channel and mold his blood to immobilize and assassinate. 

Weaknesses: Channelling so much blood would bound to result in blood loss and the main feedback he should experience is fatigue. However due to extensive nerve damage he is unable to feel pain and exhaustion.
