Kaagh

Commander Kaagh the Slayer was attached to the Tenth Sontaran Battle Fleet's Special Assault Squad. He was the lone survivor of a failed invasion of Earth by the Sontarans.

Avenging his Race
When Luke Rattigan destroyed the Sontaran flagship (DW: The Poison Sky), Kaagh's space pod was sent off course and crashed down to the planet Earth. Despite damage to the ship and exposure to G-force which might have killed him, injured and scarred on his face and one hand, Kaagh survived. As part of the Special Assault Squad, Kaagh's purpose was to infiltrate deep behind enemy lines in order to predict and anticipate their movements.

Kaagh hoped that by doing this he could make up for his fleets failure to conquer Earth. He began to began a covert attempt at destroying Earth and make himself a hero, "Kaagh the Avenger", then "Kaagh the Destroyer". To this end, he used a neural control implant on Professor Nicholas Skinner and his daughter Lucy, both of whom ran Tycho, a radio telescope nearby. Kaagh planned to use the telescope to bring down Earth's many orbital satellites in a coordinated attack on the planet's nuclear power plants, which would have rendered the planet uninhabitable.

His plan was discovered by Sarah Jane, her son Luke and their friends Clyde and Maria. Kaagh attempted to kill her and her young friends whom he considered as 'half-forms'. However before his plan could come toeffect Kaagh was attacked in his probic vent by Maria's mother, Chrissie and forced to return home to Sontar in his scout-ship. However Sarah Jane suspected that he would one day return. (SJA: The Last Sontaran)

Return of Kaagh
Too ashamed to return to Sontar Kaagh began working as a mercenary for the cephlapod Bane who had found the conciousness of Horath and used Kaagh as a go between for its transportation from planet to planet. A few weeks after this he met Mrs Wormwood, a member of the Bane Family whom had been cast out for her actions. He found that there was a high price on her head but she persuaded him to help her control the universe. He aided her so that they could survive. They both plotted to become Emperors of the Galaxy. Mrs Wormwood travelled to Earth closely followed by Kaagh who came in during a seige by the Bane Kindred. He found Mrs Wormwood and murdered her attackers. (SJA: Enemy of the Bane) They then stole Luke and the Tunguska scroll which would show them where Horath was buried. Luke escaped but Kaagh managed to catch him. However Mrs Wormwood was growing tiresome of him. In the end she offered Luke a place at her side and double crossed Kaagh calling him a blundering idiot. Eventually he saw the light and in a last ditch attempt at honour he threw himself and Mrs Wormwood into the portal to Horaths world. His fate is as unknown.

Equipment
Kaagh had access to an even higher level of technology than the likes of Commander Skorr. He had a smaller, more compact blaster weapon, a different type of communicator, an automatic helmet that could retract into his armour and a personal cloaking field. He also employed the use of neural implants as opposed to the more common hypnosis methods Sontarans tend to use. Kaagh sent out drones that resembled large plasmic spheres to act as scouts but also had attacking ability. (SJA: The Last Sontaran). His communicator also seems it can power other electronic weapons such as Mrs Wormwood Sonic disruptor. (SJA: Enemy of the Bane)
