Magnus Greel

Magnus Greel was the Minister of Justice for the Supreme Alliance in the 51st century. When the Alliance fell, he became a wanted war criminal. He escaped by using an experimental time cabinet. He went first to the late 19th century China and then to London, where he continued his depraved activities on a smaller scale. This made him the first human to (officially) travel through time.

Biography
During Greel's time, the Earth was split into a number of warring Alliances. The Icelandic Alliance and Greel's Supreme Alliance were at war. The Icelandic Alliance fell when Greel had the doll-like but homicidal cyborg known as the Peking Homunculus assassinate its commissioner, an event which nearly precipitated World War VI.

He considered himself a driving force in the project in which his nation pioneered time travel. Apart from that he also personally experimented with the catalytic extraction chamber, an attempt to cannibalise life energies. 100,000 "enemies of the state" would be massacred for these experiments.

As the Supreme Alliance's ironically named Minister of Justice, Greel carried out an atrocity earning him the title of the "Butcher of Brisbane". (DW: The Talons of Weng-Chiang) A human monster, Greel would think nothing of unprovoked murder and cannibalism (DWM: Under Reykjavik).

After the defeat of the Supreme Alliance in the Battle of Reykjavik, Greel used a time travel process utilising a time cabinet to travel back in time to the 19th century China with the Peking Homunculus.

Greel passed himself off as a god, Weng-Chiang, to a lackey, Li H'sen Chang, and, with Chang posing as a conjurer and the Homunculus as Mr Sin, a ventriloquist's dummy, eventually found themselves in London.

The passage through time had caused great damage to Greel's DNA, deforming him. He wore a mask and concealing clothes to hide his true form. While Greel lived in fear of Time Agents, Chang abducted young women for him so that he might use their life energy to restore himself, a method which was inherently flawed and only accelerated the damage.

Eventually he tried to restore his body using the time cabinet, but was instead shoved inside his own extraction chamber by the Fourth Doctor, resulting in fatal cellular collapse. (DW: The Talons of Weng-Chiang)
