Caitlin "Cat" McQuiston, code name Backdraft, was a combat instructor at Whateley until she was killed by Terror during the Halloween invasion. She was third in seniority in the range crew after Sergeant-Major Sean Burlington-Smythe and Gunnery Sergeant Oscar Bardue. Unlike the rest of the range crew she did not serve in any military before coming to Whateley but was a member of the LAPD SWAT and mutant investigations division, which she left shortly after her promotion to Lieutenant. Cat McQuiston alternated between teaching on range two, the pistol/SMG range and tutoring Manifestors and Avatars. Easily the most popular teacher among the students on the ranges, Cat was far more likable than her compatriots.
Bardue calls her "probably one of the most powerful manifestors and avatars I have ever seen".
