Biography
When the Fugitive Doctor discovered a plot by a member of the High Council, she had Gat's forces reinforce her. Gat arrestied both the Councillor for his planned genocide and Taslo for aiding him. Not long afterwards, Gat was summoned by Tecteun, who informed her that the Doctor had gone rogue, tasking Gat to bring her back. (COMIC: Origins)

Gat subsequently worked with the Judoon to capture the Doctor following their disappearance, and upon discovering the Doctor's location, she executed Lee Clayton, the Doctor's "companion". When she captured the Doctor, Gat was surprised to also be confronted with another incarnation of the Doctor. When she later revealed to the other Doctor that she was an agent of Gallifrey, Gat was horrified to find that Gallifrey was gone in her time, destroyed by the Spy Master.

Gat was killed when she tried to shoot the Fugitive Doctor with a laser rifle, as the Doctor had re-calibrated the weapon to shoot the one holding it. (TV: Fugitive of the Judoon)
