T'zim-Sha travelled to Earth in a pod-like spaceship in order to find Karl Wright to claim as his trophy, so he could become the leader of the Stenza.
He arrived in a forest where Ryan Sinclair was, looking for his bike after he accidentally gave T'zim-Sha permission to land on Earth. Ryan went away to find his grandparents, before Rahul and Andy took it away. Rahul's sister had been taken away by the Stenza seven years beforehand and Rahul wanted T'zim-Sha to bring his sister back.
T'zim-Sha exited his pod and killed Rahul. After the Thirteenth Doctor along with Ryan, Yasmin Khan, Graham and Grace O'Brien arrived at the pod's location, the Doctor used the technology within the pod to create a new sonic screwdriver. (TV: The Woman Who Fell to Earth)
