History
The Tzun were a spacefaring species by at least 23,000 BCE. Shortly after developing space travel, they fought the Darklings of Yuggoth, which corrupted their DNA. They perfected genetic engineering and began integrating new species into their Confederacy by combining their DNA with theirs.

In 1957, the Tzun attempted to invade Earth with the aid of the Master, but were defeated by the Doctor. (NA: First Frontier)

In 1983, a Tzun, nicknamed Tony, was a member of Isaac Summerfield's team. (NA: Return of the Living Dad)

In 2172, the Tzun attempted to conquer the Veltrochni. (NA: First Frontier) Though the Tzun were successful at the beginning, as the war carried on the Veltrochni packs joined forces and fought back. They drove the Tzun off, destroyed many of their colonies planets and effectively collapsed the entire confederacy. The Veltrochni became renown for their power after this. (MA: The Dark Path)
