Zaroff's guard

One of Zaroff's guards in Atlantis searched for the Second Doctor after he escaped from Zaroff's laboratory. He brought Jamie and Ben to the Overseer in the mines. He searched for the Doctor again after he was rescued from being sacrificed with Ramo by his friends.

While searching for the Doctor, he and another guard went over to Nola's stall, where Polly was hiding. He had his fellow start to poke holes in Nola's carpets with his trident until Nola told them off.

He was present when Zaroff shot Thous.

He was later stationed to guard one of the generating stations. When Ben Jackson pretended that the Doctor was a prisoner and he was escorting him, the guard demanded the password, and they tricked him into revealing it was "Oscar". He then let them in. (TV: The Underwater Menace)
