Katrina "Kitty" Tsang is one of the cutest killers in the known ‘Verse. She has a twitchily happy disposition and usually has a smile on her face (next to the nasty scars). This makes those who know her best a bit worried and edgy. Kitty is a freelance mercenary, and the first person Jon will call if he's short-handed for a job, or knows that things are likely to be interesting enough to require more firepower.

Not much is known about Kitty, mostly because she doesn’t talk about her past much. And frankly, no one really wants to risk prying. At some point in the past she was a gun runner on the Rim, and Jon met her via Teddie Long, with whom she used to live for a while, for reasons that remain unclear.

Kitty seems to live by the maxims "Any fight you can walk away from obviously wasn't violent enough" and "Oooh! That's CUTE!" Although she is a very effective killer, she is loyal to her employer and crew. It’s easy to forget that Kitty is a killer and only see her friendly side - but usually only until she says something particularly cold and creepy.

Kitty is a combat and weapons expert - ALL kinds of weapons. She has even been known to design some weapons and make modifications to her own gear. If one were to observe her closely one would notice the brutal efficiency of her techniques, borderline military. She also has a variety of scars, origins unknown, not all of them on the outside.
