Crosshair is Clone Force 99's sniper, enhanced for eyesight and precision, and the member of the squad whose inhibitor chip functions as designed. He is voiced by Dee Bradley Baker.
The first season sets him against his own squad as an Imperial officer, and the show's most interesting decision is what it does next: the chip is eventually removed, and Crosshair does not immediately come home. He stays with the Empire for a while, because the loyalty was never purely chemical — some of it was a real preference for order, rank and a side that wins.
What follows across the second and third seasons is the closest the franchise has come to writing a collaborator: a man who chose the wrong thing, was made to choose it harder, and has to be re-admitted by people who remember. His hands shake for most of the third season. The show never fixes that.
