Gat
Gat was a Gallifreyan who worked with the "Fugitive" Doctor for the Division. She worked with the Judoon to capture the Doctor following their disappearance, and upon discovering the Doctor's location, she executed Lee Clayton and proceeded to search for the Doctor. When she captured the Doctor, Gat was surprised when she was confronted with the Thirteenth Doctor. She cited the Blinovitch Limitation Effect, terming it an "abomination." When she later revealed to the other Doctor that she was an agent of Gallifrey, Gat was horrified when the Thirteenth Doctor told her Gallifrey was gone in her time, and presumed she was lying.
Gat was killed when she tried to shoot the Fugitive Doctor with a laser rifle, as the Doctor had been re-calibrated the weapon shoot the one holding it. (TV: Fugitive of the Judoon)
