Mighty Jagrafess of the Holy Hadrojassic Maxarodenfoe

The Mighty Jagrafess of the Holy Hadrojassic Maxarodenfoe (often shortened to the Jagrafess, also called the Editor in Chief or Max) was a pseudopod-creature and the overseer of the Editor and the secret controller of Satellite Five in 200,000.

Biology
The Jagrafess was a gigantic, gelatinous purple/dark pink creature similar to a slug in shape. He was sentient and his only known methods of talking seemed to consist of growls and screeches. He had a life span of about three thousand years, with sharp, vicious teeth and several vestigial eyes. His metabolic rate, however, meant that he had to be kept at low temperatures to survive. (TV: The Long Game)

Biography
The Jagrafess was put in charge of the ersatz Fourth Great and Bountiful Human Empire in the year 199,909 (TV: The Long Game) by the Dalek Emperor, as a pawn in a stratagem spanning several hundred years. (TV: The Parting of the Ways) Away from his home planet, only a facility like Satellite Five could produce enough cold air to sustain him. If no cold air was supplied, the Jagrafess would overheat and explode spectacularly. The heat from Floor 500, where the Jagrafess was installed, was channelled away to the rest of the station, allowing the Jagrafess to remain in a cool climate. Since the Jagrafess could not operate Satellite Five's controls, a human known only as the Editor carried out his orders.

The Ninth Doctor discovered the Fourth Great and Bountiful Human Empire was being controlled by the Jagrafess in 200,000. With the Doctor helping her realise the irregularity of the heating system, Cathica Santini Khadeni used her infospike to channel the heat back towards Floor 500, killing him by causing him to explode. (TV: The Long Game)

Producer Andre Kulekvo had kept the remains of the exploded Jagrafess on the Floor 500 studio for his show Ghost v Whatever. (PROSE: Extraction Point)

After his death, the Daleks went on to other stratagems and renamed the Satellite the Game Station. (TV: The Parting of the Ways)

The Doctor would later compare the media being in control of Arkannis Major to "the thing on Satellite Five", not remembering the Jagrafess' name. (PROSE: The Stealers of Dreams) The Jagrafess was later mentioned by the Eleventh Doctor. (PROSE: The Silent Stars Go By)
