Tzim-Sha

Tzim-Sha, mockingly referred to by the Thirteenth Doctor as Tim Shaw, was a Stenza warrior who sought to become the 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 came ahead in his pod, waiting inside for the coils to find his target before breaking out and killing Rahul, taking one of his teeth as a prize. He then began searching for the coils in order to learn where and who his target was. While searching for the coils, he encountered Dean, who through salad at him, mocking his appearance. Angered, Tzim-Sha killed him and took one of his teeth as well.

Upon finding the coils, he was confronted by the Thirteenth Doctor, along with Ryan, Graham, Grace and Yasmin who ordered he not hunt on Earth and flee back to his people. However, Tzim-Sha refused, threatening to kill the Doctor if she tried to stop him. He absorbed the data and then used a short-range teleport to reach his target, Karl Wright, at a construction site.

There, he killed the security guard and proceeded to climb up Karl's crane to reach him. However, the Doctor arrived with assistance and proceeded to convince Karl to leave his crane and climb towards her so he could jump to safety. However, Tzim-Sha caught up to them, grabbing Karl to take back with him. Not giving in, the Doctor leapt across, stating he couldn't leave as she had stolen the recall device from his pod that would allow him to return home and threatened to destroy it. Calling her bluff, Tzim-Sha detonated the DNA bombs his coil implanted in the Doctor and the others.

Although, the detonation affected him instead as the Doctor has transferred the bombs into the coil's data, meaning Tzim-Sha had downloaded them. With no choice, Tzim-Sha let Karl go and took the teleport to flee back to his planet, but not before Karl kicked him off the railings. (TV: The Woman Who Fell to Earth)
