Gat

 was a Gallifreyan who worked with the Doctor. She worked with the Judoon to capture 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."

She was horrified when the Doctor told her Gallifrey was gone and didn't believe her. (TV: Fugitive of the Judoon)
