Judoon

The Judoon were a race of rhinocerid humanoids frequently employed as a mercenary police force. They were known to be single-minded in carrying out their tasks, without regard for unintended consequences of their actions.

Biology
Judoon were two-metre high humanoids with stocky builds and rhinoceros-like heads. They had large lungs and could breathe even in environments with low levels of oxygen. They were resistant to even harsh physical assault, such as being hit with a marble statue. (TV: Smith and Jones) Judoon had yellow blood. (TV: Prisoner of the Judoon) They also had rather small brains; a Judoon brain was able to fit in a chest that could easily be held in a humanoid palm. (WC: Prequel (A Good Man Goes to War)

Culture
The Judoon were known for their strict obedience to the law and their brutal efforts in maintaining it. Crimes like physical assault towards a Judoon incurred the death penalty, without chance for trial. The Doctor described them as logical, but stupid, and they seemed to favour methodical patterns of behaviour to a fault. (TV: Smith and Jones) Even on crucial missions, Judoons would obey local laws and signs, including traffic laws and "Authorised personnel only" and "Pay and Display" signs. Similarly, they would follow mission procedure rigidly and always get a form signed when commandeering transport. The Judoon were trained to use all known forms of transit, albeit not very well in the case of cars. (TV: Prisoner of the Judoon)

Their language was composed of many one-syllable words ending in a vowel, generally an "o" sound (such as "blo mo co jo") but occasionally an "a". Each sentence was composed of several of these words strung together. (TV: Smith and Jones, The Stolen Earth, PROSE: Judgement of the Judoon)

Although they did not laugh, Judoons would shake and make laughter-like noise when amused. (PROSE: Judgement of the Judoon)

A favourite sport among the Judoon was nukeball, but it was illegal on their planet to avoid the destruction of the population. (PROSE: The Coming of the Terraphiles) Judoon did not like opera. (COMIC: The Great Mordillo)

Technology
In general, Judoon technology was a dark red or black colour, and most instruments, such as their weapons, scanners and translators, were thick and pen-shaped, similar to a large sonic screwdriver. (TV: Smith and Jones)

Communication and scanning
The Judoon had scanners which would tell the Judoon the species of the scanned being. However, the scanners could be fooled by previous close contact with another species. Metamorphic beings capable of altering their internal biology using assimilated biomatter could also deceive the scan. They also were known to use a thick marker pen to mark "catalogued" people — those who had been scanned and deemed not to be a suspect — on their right hand.

The Judoon had translation devices which worked by analysing the recorded voice of a being. The translation was reciprocal. It also had a contact device that reached every Judoon helmet, allowing the Judoon Captain to give orders with a press of a button. (TV: Smith and Jones)

Judoon rockets
The Judoon rockets were large, cylindrical craft with four boosters and four claws at the bottom which served as landing gear. (TV: Smith and Jones)

Other transportation
The Judoon also had teleport technology. (PROSE: Judgement of the Judoon, TV: The Pandorica Opens, A Good Man Goes to War)

The Judoon were known to use an H2O scoop to transport buildings across space, and shield them with force fields as required by Galactic Law. (TV: Smith and Jones)

Judoon operated various land vehicles to find lawbreakers, including motorbikes that hovered, tanks and tall, all-terrain machines with four legs. (COMIC: Prisoners of Time)

Weaponry and armour
The "execution" punishment was delivered using a directed energy weapon with a red beam which could incinerate the target.

Judoon wore heavy black armour. (TV: Smith and Jones)

Other
In the 25th century, the Judoon were able to remotely lock down the communication and transport systems of spaceships. (PROSE: Judgement of the Judoon)

History
The Judoon were originally a warlike race. They became mercenaries for various Galactic organisations, including the Padrivole Regency and the Shadow Proclamation. (WC: Captain Jack's Monster Files) They came to be one of the universe's most trusted mercenary races largely at the expense of the Ogrons, who lost their dominant position as "hired guns" because of a string of defeats by the Third Doctor. (COMIC: Fugitive) In 102, the Judoon were among the races who joined the Alliance. They came to Stonehenge and helped imprison the Eleventh Doctor in the Pandorica in order to save the universe. (TV: The Pandorica Opens)

In 1902, while working for the Galactic Council, the Judoon were conned into assisting in a plot to use Temporal Reversion Devices on Earth. As they abducted Balmoral Castle during this, the misunderstanding would be known as "the Balmoral Incident". As a result of this, the Judoon were banned from Earth. (WC: Captain Jack's Monster Files, PROSE: Revenge of the Judoon) As events transpired, however, this ban was ultimately temporary.

At some point after the 1980s, the Judoon came to Earth, despite it being out of their jurisdiction. They came to the house on Allen Road, looking for an Eye of Akasha. The Fifth Doctor followed them and was forced to help them look for it after they threatened Tegan. He handed it over and let them leave, but using sleight of hand he switched the Eye with a cricket ball. (COMIC: The Forgotten)

In 2008, a Plasmavore who was pretending to be an old lady called Florence Finnegan murdered the Child Princess of Padrivole Regency 9 and then escaped to the Royal Hope Hospital. The Judoon used an H2O scoop to transport the Royal Hope Hospital to the Moon, as they had no jurisdiction over Earth. The Plasmavore had drunk the blood of a human, though, and passed as a human to their scanners. The Tenth Doctor was able to make her drink his blood, making her seem like an alien again. Martha Jones then convinced the Judoon to check her again. Finding her to be the alien they sought, they killed her. The Judoon then returned the hospital to Earth. (TV: Smith and Jones) The Judoon also investigated Slitheen activities on Earth. (TV: Revenge of the Slitheen) When the Tenth Doctor and Donna Noble came to the Shadow Proclamation to investigate the stolen planets, the Judoon were working there. (TV: The Stolen Earth)

In 2009, Captain Tybo of the 1005th Judoon Guard crashed on Earth while transporting the prisoner Androvax. Androvax escaped, and Tybo (wounded in his pursuit) was forced to accept help from Sarah Jane Smith and her friends. He was eventually able to track Androvax down and return him to custody. He initially sentenced Rani and Clyde to disintegration for interfering with his pursuit (by locking him in a EM shielded room), but he later commuted their sentences to planetary confinement after they helped prevent Androvax from escaping. (TV: Prisoner of the Judoon) The Judoon later took Androvax to a prison planet in the Calysteral cluster. (TV: The Vault of Secrets) In 2010, a Judoon was at the bar where the Tenth Doctor came to visit Jack Harkness one last time before his regeneration. (TV: The End of Time)

In late 2009 the Krulius captured several aliens and stored in a hologram. Mr Smith informed the Judoon that the Krulius was at the Doloth Star Base. The Judoon, led by Captain Tybo, brought the Krulius to their prison ship. (COMIC: Monster Hunt) All the captured aliens were set free. However the Krulius escaped from the Judoon and had managed to take clone cell samples of his former captured aliens and the Judoon with him, which allowed him to grew perfect copies of these aliens. (COMIC: Return of the Krulius)



In late 2010, three Judoon took part at the army of alien slaves led by the Krulius to attack Sarah Jane's house. When Clyde defeated several of the aliens, the Judoon regrouped with the army and the Krulius ordered them to retreat. Sarah Jane thought that the aliens in the army were under some kind of hypnothic influence. (WC: Defending Bannerman Road)

When the Council of Dead were planning to sell humans in slavery, they had to avoid the attention of the Judoon. The Eleventh Doctor believed he could scare off the buyers, the Zu'nar, with the threat of the Judoon. (PROSE: Attack of the Snowmen)

In 2487, the Judoon investigated the Invisible Assassin. They tracked it to New Memphis. The Tenth Doctor believed they would cause more harm than good and agreed to work with the Judoon commander, Rok Ma, provided the other Judoon kept off the planet. With the help of Nikki Jupiter, they were able to find the Invisible Assassin, bring down two criminal empires and find the bombs planted within Terminal 13. After the mission, Rok Ma left the Judoon forces and joined Nikki's detective Agency. (PROSE: Judgement of the Judoon)

In the 52nd century, Dorium Maldovar procured security software for the headless monks by extracting it from the memory of a Judoon trooper. (WC: Prequel (A Good Man Goes to War)) Later, a squad of Judoon were part of the Eleventh Doctor's army which assaulted Demons Run in order to rescue Amy Pond and her baby. When Colonel Manton gave the Clerics the order to abandon Demons Run, the Judoon escorted them off the station. (TV: A Good Man Goes to War) In 51,007, some Judoon took part in the tournament for the Arrow of Law. (PROSE: The Coming of the Terraphiles)

In 5,000,000,057, the Judoon had become corrupted and had joined forces with the Cybermen. Together, the two armies invaded New Earth with plans to upgrade and enslave the population. However, they were stopped by the Tenth Doctor and Martha. (COMIC: In-Flight Entertainment)
