Tsinniyans

Tsinniyans are a fictional alien species from the television series "Doctor Who". They are a race of small, insectoid creatures with a distinctive appearance, characterized by their large, compound eyes and segmented bodies. Tsinniyans are known for their advanced technology and their role as the creators of the Cybermen, a race of cyborgs that have been a recurring antagonist in the series.

The Tsinniyans first appeared in the 1966 episode "The Tenth Planet", where they were depicted as a peaceful and advanced civilization. However, their technology was later used by the Cybermen to create their own bodies, leading to a long-standing conflict between the two species. The Tsinniyans have since made several appearances in the series, often serving as a source of advanced technology for the Doctor and their companions.

Despite their advanced technology, Tsinniyans are not invincible. In the episode "The Tenth Planet", the Doctor and his companions are able to outwit the Tsinniyans and escape their planet. In the episode "The Tsinniyans", the Doctor and his companions are able to infiltrate the Tsinniyans' base and steal their technology, leading to the creation of the Cybermen.

Tsinniyans are a recurring element in the "Doctor Who" universe, serving as a reminder of the advanced technology that can be used for both good and evil. Their appearances in the series have helped to shape the show's portrayal of alien civilizations and their interactions with the Doctor and his companions.
