Judoon

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

Biology
Described as rhinoform bipeds, (AUDIO: Judoon in Chains) Judoon were two-metre high humanoids with stocky builds and rhinoceros-like heads. (TV: Smith and Jones) They descended from the Juran. (AUDIO: Patience)

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, or fit in a teaspoon. (WC: Brain Trafficking, AUDIO: Judoon in Chains) The Judoon had canines, incisors, molars and pre-molars - the teeth of an omnivore, which meant they ate meat and vegetables. (WC: Teeth and Eating)

Judoon were largely non-sexually dimorphic, with males and females looking and sounding identical. The only noticeable difference was that females had hair on their scalps, while males were completely bald. (TV: Fugitive of the Judoon) Baby Judoon were called Judlings, and resembled baby rhinoceroses. (AUDIO: Patience)

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 Tenth Doctor described them as logical, but stupid, and they seemed to favour methodical patterns of behaviour to a fault. While they would always attempt to arrest any criminals, they were quick to execute them if they did not comply. (TV: Smith and Jones) A Judoon captain once stated that Judoon preferred to eradicate law-breakers, rather than incarcerate them, as this was the cheaper option. (COMIC: Gangland)

Even on crucial missions, Judoon 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 strict compliance with an established order even made them despise development even with their culture, and those who went out of their norms were often ostracised. (AUDIO: Judoon in Chains) They also had a complex statute of limitations, as they arrested a version of the Doctor who was several centuries older than the one who committed a crime. (TV: Fugitive 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, Judoon would shake and make laughter-like noise when amused. (AUDIO: Judoon in Chains, 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)

The Judoon had nothing to compare with poetry. (AUDIO: Judoon in Chains)

If a Judoon lost their horn under any circumstance, it was considered a great dishonour, especially amongst captains. (TV: Fugitive of the Judoon)

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 or stamp 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, Fugitive of the Judoon)

They used crime scene forensic scanners. The Seventh Doctor bought a second hand one from a retired Judoon. (AUDIO: The Blood Furnace)

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, AUDIO: Judoon in Chains)

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

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, and with their helmets on closely resembled Sontarans. (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)

The Thirteenth Doctor considered Judoon chocolates to be of high quality. (PROSE: The Secret in Vault 13)

Early history
The Judoon were originally a warlike race. They became mercenaries for various Galactic organisations, including the Padrivole Regency and the Shadow Proclamation. (WC: ) 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)

Early in universal history, the Judoon joined Rassilon in the Alliance of Races against the Hyperions. After the Hyperions were defeated, the Alliance then went on to purge the universe of other threats to universal harmony, one of those threats being Count D'if of the Cybock Imperium. (COMIC: Gangland)

19th century
Judoon Captain Kybo of the Nineteenth Judoon Interplanetary Force became stranded in a Victorian circus, on 19 May 1884. He was bound in chains and forced to perform. Hot on his tail, the Sixth Doctor followed closely behind and met the same fate. Together with Eliza Jenkins, the three of them successfully delayed the following fleet of Judoon, and successfully revealed to the galaxy the truth behind Meretricious Gedge's plans regarding the terraforming of an inhabited planet. (AUDIO: Judoon in Chains)

20th century
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: , PROSE: Revenge of the Judoon)

In 1963 the Judoon attempted to prevent the Cybock Imperium from stealing the Time-Gun of Rassilon from the vaults on Janizzar. The member of the Imperium used the time-gun on the Judoon captain, wiping them from history and preventing them from having brought their platoon to the planet. (COMIC: Gangland)

In 1966, a "big fight" resulted in a Judoon placing her child in a survival pod and sending them to safety, with the pod crashing on Earth in Ireland. The isolated Judoon was cared for by Patricia Kiernan, discreetly observed by the Thirteenth Doctor, until its people came to rescue them. (PROSE: The Rhino of Twenty-Three Strand Street)

21st century
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 own 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) They had forced some members of the Slitheen family, including Kist Magg Thek Lutiven-Day Slitheen, out of Raxacoricofallapatorius. (PROSE: 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 One Thousand and Fifth 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 an EM shielded room), but 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)

Some time after these events Clyde Langer told jokes while some Judoon were present. The jokes weren't translated well and the Judoon put Clyde into prison. Mr Smith and Rani Chandra convinced Captain Tybo to let Clyde go, by giving food to the hungry Judoon. (WC: Teeth and Eating)

In late 2009, the Krulius captured several aliens. 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, having 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 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 2010, three Judoon were part of 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 hypnotic influence. (COMIC: Defending Bannerman Road)

In 2020, (TV: Can You Hear Me?) the Judoon, led by Pol-Kon-Don, were hired by the Time Lords to hunt a past incarnation of the Doctor in Gloucester. The platoon initiated a forcefield around the city that was infiltrated by the Thirteenth Doctor and her companions. The Judoon reluctantly worked with the Doctor to find the fugitive, however upon Ruth Clayton's momentary return to her true self, the platoon were humiliated and Pol-Kon-Don's horn was removed, a source of huge embarrassment for the platoon. Later, the platoon scooped the TARDIS into their ship, but upon the death of Gat, they retreated, following threats by two incarnations of the Doctor. (TV: Fugitive of the Judoon)

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)

25th century
On 14 June 2426, the Judoon collectively arrested the Raxacoricofallapatorian race for their illegal annexation of Tivoli. By placing Tivoli under their jurisdiction, they inadvertently led the Tivolians to treat them as their new conquerors and masters; as per the Tivolians' habit, they were consequently regarded as heroes. The Judoon ended up remaining masters of Tivoli until the Kraal overpowered them on 9 July 2559. (PROSE: Time Traveller's Diary)

In 2487, the Judoon investigated the Invisible Assassin and tracked it to New Memphis.

After the mission, Rok Ma left the Judoon forces and joined Nikki's detective Agency. (PROSE: Judgement of the Judoon)

Later history
In the 51st century, a troop of trainee Judoon were hired by the Intergalactic Trust to police Vallarasee. They enforced the rules literally, without regard for the decaying state of the underwater city, and decided to abandon the city when the dome protecting the city broke and the sea began flooding in. The Tenth Doctor persuaded trainee Clo to try to help evacuate the human tourists. Clo convinced his fellow Judoon to save the tourists by moving the city above the surface with an H20 scoop, as they were all technically guilty of vandalism. The Judoon barred the tourists from returning to Vallarasee as punishment and arrested both the Trust representative, Andrea, and the Fin Chancellor for their actions leading to the dome’s collapse. (AUDIO: One Mile Down)
