Grigor (And You Will Obey Me)
Grigor was a KGB agent turned mercenary.
Biography
After he and several of his comrades arrived in 2016 Hexford by helicopter, he threatened the Fifth Doctor and Annie with a staser-gun, also revealing to the Doctor that he was mistaken in the assumption that he and his comrades were working directly for the Decayed Master, as "his 'Master' was a she". His interrogation of the Doctor and Annie was, however, cut short by the arrival of Jade Nymph, a Dragonhunter who had also come seeking the Master.
Nymph "disarmed" Grigor by stunning him with an electrical charge from her stinger, which knocked him unconscious. The Doctor looked him over and deemed that he would live. The Doctor convinced the Dragonhunters not to liquefy and consume Grigor's brains for information by showing them that he had much more tangible data (namely the Master's TARDIS key) and then told Annie to tie Grigor up for safety's sake. She then set out to interrogate him, and eventually got the Global Positioning System coordinates of his employer's abode out of him. (AUDIO: And You Will Obey Me (audio story)
