Drahvin One

Drahvin One was one of the cloned, semi-intelligent Drahvin soldiers serving under Maaga, who became stranded on the desintegrating planet in Galaxy 4. She was sent out along with Drahvin Two to bring the Doctor, Steven and Vicki to their ship. They managed to disabled the Chumbley escorting them with a magnetic mesh but were unable to retrieve it and were forced to retreat with the three travellers when more Chumblies approached.

Once back at the ship, Drahvin One joined the other Drahvins in driving off a Chumbley that had brought a message from the Rills. She and Drahvin Two were chastised by Maaga for losing the mesh. Having gone out on patrol with the other Drahvin soldiers, they returned in time to put an end to a fight between Steven and Maaga and to threaten Vicki's life in order to force the Doctor to reveal the planet would destroy itself in two dawns' time.

She was nearly tricked by Steven into giving him her gun and stealing Maaga's for herself when he suggested Maaga would be pleased if she did. She expressed confusion that they did not go out on patrol at the usual time and at Maaga's insistence that the Doctor and Vicki would return for Steven. On solo patrol, she encountered the Doctor, Vicki and a group of Chumblies. Failing to be convinced by their claims of friendship, she fired on the Chumblies but was overpowered. She ended up being imprisoned in the spaceship with the other Drahvins when Steven was rescued.

After the Chumbley on guard had been destroyed by Drahvin Three, Drahvin One joined Maaga and Drahvin Two in attacking the Rill ship to try and capture it before the planet's destruction but they were defeated by the Chumblies and watched in horror as the ship took off without them. Maaga then decided to hijack the TARDIS instead but they were held back by the remaining Chembley and ultimately perished in the planet's destruction. (DW: Galaxy 4)
