(Skybox Ultraverse trading card #47) - Kaitlyn O'Hare became an assassin for hire on a cash-only basis. She relished the hunt more than the kill, and selected mostly male targets whom she would seduce before brutally murdering.

(Prototype#2 (fb) - BTS) - At some point, O'Hare had metal implanted into her body that reinforced her bone structure and gave her extendable claws from the fingernails on her right hand.

   UltraTech boss Stanley Leland was concerned about the bad publicity generated by ex-employee Bob Campbell, so his assistant Marjorie Fredericks (later Veil) hired Backstabber to eliminate him.

(Prototype#2) - Backstabber waited for Campbell at a bar and approached him, posing as a talent agent. Sitting nearby, Aladdin agent Jake Alexander vaguely recognized her, but left. Drinks progressed and Campbell took her back to his place, where she came on strong, then slashed him several times, separating him from his prosthetic arm. His protective cat Thelma provided a distraction while he escaped into his garage and quickly put on the basic parts of his new armor. He rapidly slotted in a circular blade attachment and shattered her fingernail blades.

(Prototype#3 (fb)) - Backstabber ran off howling into the night, threatening to return.

Comments: Created by Len Strazewski & Tom Mason (writer), David Ammerman (pencils), and James Pascoe (inks).

It looks like it's only her right hand that's augmented with extendable blades, but there are a couple of panels where the art's not that clear.

It's possible that her enhancements were bought from NuWare (a subsidiary of UltraTech).
