Ymgarl Genestealers

Ymgarl Genestealers
The Ymgarl Genestealers were first encountered on the moons of Ymgarl about 200 years before the invasion of Hive Fleet Behemoth.

History
The Ymgarl Genestealers were first not thought to be part of the tyranid race, but were thought to be natives to the moons of Ymgarl. However, 200 years later, during the invasion of Hive Fleet Behemoth, the Tyraids used Genestealers as shock troops and infantry. Genetic annalisis of the tyranid bodies found on Maccrage, the planet in which Hive Fleet Behemoth suffered its defeat, revealed that the Ymgarl Genestealers were infact Tyranid orginisms. Since then, Genestealers have been used in countless battles by the Tyranids.
