The Creator (The Battle of Ranskoor Av Kolos)

The Creator was a god central to the religion and culture of the Ux. Due to the Ux's isolation from the rest of the universe, they mistook the Stenza Tzim-Sha for the Creator when he arrived on Ranskoor Av Kolos in 2018 after being teleported by a Stenza recall device corrupted by the Thirteenth Doctor. However, when the Doctor revealed the truth to them in 5425, they realised that Tzim-Sha had deceived them. (TV: The Battle of Ranskoor Av Kolos)
