Wonder Woman

From Shadow Unit Wiki

Wonder Woman is a nickname for Nicolette Lau.

Chronologically, the first reference to Nikki as Wonder Woman is in episode 1x07, "Overkill", after the big fight scene:

Maria nodded, with a sidelong glance at Lau. She extended Lau's empty firearm, the slide locked open. Lau took it, exchanged the magazine, and re-holstered the weapon, as Maria said, "O.K. Corral. Bullets flying everywhere, and none of 'em hit you. You're Wyatt Earp."

"Actually," says Chaz, "that gunfight wasn't at the OK Corral. It was a block away--"

"On Fremont Street," Brady finished, with an eyeroll. He punched Chaz in the uninjured arm, and Chaz grinned. "Shut up, kid."

Lau held up her arms, crossed at wrists as if blocking something, hoping her hands weren't shaking visibly. "I am not. See these? Bullets and bracelets. Wonder Woman. Bulletproof." [1]
