Tzim-Sha

Tzim-Sha, mockingly refered to by the Thirteenth Doctor as Tim Shaw, was a Stenza warrior who sought to become leader of his people.

Tzim-Sha used a swarm of Gathering Coils in order to locate a trophy to take back to his planet, despite this being against his species' rules.

He was defeated by the Doctor when she planted the coil's DNA bombs onto Tzim-Sha, and he was teleported back to his planet. (TV: The Woman Who Fell to Earth)
