Kraal (species)

The Kraal are a race of advanced humanoids native to Oseidon.

Physical Appearance
Kraals are humpbacked, gargoyle-like humanoids with lumpy grey skin, unusual facial ridges and a rhinoceros-like horn. They generally wear striped tunics. (DW: The Android Invasion)

Technology
The Kraal have a wide variety of technological devices. One of the most widely used in their androids. These androids are made in the form of a certain person, generally a Human. They have most of the memories of the subject, though they are bullet-proof and loyal to the Kraal. In order to create these androids, the Kraal needed to scan the brain of the subject or someone who had dealt with the subject. This scan is highly painful and can cause brain damage if it goes on for too long.

As well as androids, the Kraal also have advanced genetic modification techniques and replication techniques. They could create a deadly virus or recreate an entire village out of the memories gained from a brain scan. (DW: The Android Invasion)

History
The Kraal lived on a doomed world. Oseidon was getting progressively more radioactive, reaching critical levels. They were able to kidnap a Human astronaut named Guy Crayford and scanned his brain for information. They were able to create many Human-like androids and an entire British village from his memory. After testing these androids, they planned to send them to Earth with a deadly virus to infect and kill all of the Humans. This plan was stopped by the Doctor when he was able to stop the androids with Space Defense Station's radar dish. (DW: The Android Invasion)
