I'm looking at my book and thinking the Covert Ops template fits mostly what I'd like, mostly changing the weapons for nonlethal ones (tasers and such, as well as gel rounds for a pistol, though she's willing to use lethal force if necessary and carries some standard bullets as well). Probably also going to get some cyberware that improves her fisticuffs, though I need to read through that part of the book still.
Anyway, character bio:
Lorelei Clemens, Covert Ops
Lorelei initially worked as a thief, stealing from various corporations in order to make a small living for herself. Eventually, she started to take on bigger and bigger jobs from clients, and would have made a lot of money had one of her clients not decided to double-cross her, leaving her for dead in an alley. Thankfully, one of her friends and frequent clients managed to find her and get help, barely saving her life. Much of her body had to be replaced with cyberware, including both arms, but she was at least able to survive. She still works as a covert spy and thief, but is much more choosy about her clients.
Even after nearly being killed, Lorelei has a cheerful personality, and is often very optimistic. Because of this, while she's not afraid to get into a fight with someone while on a job, she refuses to actually kill anyone if it's not necessary, preferring to knock them unconscious instead. The only exception is the client who betrayed her - if she ever finds him again, she has no reservations about putting a bullet in him. She does realize that most people aren't as pacifist as she is however, and won't try to stop someone from using lethal force in a fight, though she will try and stop them from killing someone that's already helpless.
