Anti-matter (disambiguation)for other, similarly-named pages.
Striking only at night, the creature sucked the life out of its victims in a process comparable to rapid freeze-drying. The victim's body would initially disappear before returning as a lifeless, desiccated husk. (TV: Planet of Evil)
When the Morestran probe ship tried to leave with anti-matter minerals from the planet on board, it suffered technical failures and the creature attacked, killing several of the crew. It was fended off when, at the Doctor's recommendation, Salamar ordered that the force field be linked to the atomic accelerator.
The Doctor travelled across the jungle to a pool-like structure composed of anti-matter, hoping to negotiate with the creature for the return of the minerals. He was plunged into the pool with the creature and was released due to the anti-matter he had about his person. The Doctor told Sarah he had promised the creature that the mineral would be returned.
However, Sorenson secreted a canister of the minerals aboard the probe ship. He was infected by anti-matter, causing his degeneration into what the Doctor labelled an "anti-man". In order to stop the attacks by Sorenson and the duplicates created when Salamar used a neutron accelerator against it, the minerals and Sorenson submerged in the pool. With the Doctor having kept his promise, the duplicates vanished and Sorenson was returned to his former self. (TV: Planet of Evil)
