Kroton (species)


 * For the Cyberman with emotions, see Kroton (Cyberman).

The Krotons were a crystalline race from the planet Krosi-Aspai-Core.

Evolution
The Krontons evolved from predatory qasi-organic tellurium based crystal on the planet Krosi-Apsai-Core that could mimic their prey's abilities. At some point in their history they encountered a Human servo robot and, mimicking it, thus attained semi-sapience. They evolved they became semi-sentient amoured crystalline beings which fed on/psychologically linked to mental vibrations.

Recent History
The Kroton Absolute were overseen by the First Lattice, originally a fortress on the Kroton's home world, it contains the four highest brains in the Kroton Absolute. The First Lattice was moved from the Kroton home world when the war began with the Metatraxi, it took over four thousand Krontons to lift the First Lattice into orbit and it had exhausted all of them. The Krotons had crystalline bodies which can be broken down and reformed to suit the environment and the situation which they are in. (EDA: Alien Bodies)

Encounters with the Doctor
The Krotons have encountered the Doctor on at least three occasions. On one occasion the Doctor killed a pair of Krotons stuck on a planet of Near-Human slaves known as Gonds. The Krotons had enslaved and manipulated the lives of the Gonds for generations so that they might power a dynatrope (a Kroton spacecraft) with mental energy and escape the planet. The Doctor assisted in the Krotons' destruction with sulfuric acid. (DW: The Krotons)

In his six incarnation, the Doctor a dynatrope with at least four Krotons on board and assisted a group of humans again to destroy two of the Krotons, though he did allow the remaining Krotons to escape.

The third encounter was on Earth during the auction of the Relic. The Kroton Absolute intercepted a Dalek cruiser on its way to the auction and sent a Kroton of the Dalek ship in their place. The eighth incarnation of the Doctor, who attended the auction, was unaware at first of the Relic's origins or of the Krotons' presence. (EDA: Alien Bodies)
