Igby was a Soul Pirate who was sent down from the Soul Pirate frigate to capture Human children from Hyde Park for their transplants on the ship. While the anti-gravity beam began the process of extraditing the individuals from the planet, Igby was confronted by the First Doctor who succeeded in repelling Igby and conclusively knocking him from the roof of the residential building. The Soul Pirate fell and was killed. (A Big Hand for the Doctor)
