The Sontarans also feature in the Kroton solo strip Unnatural Born Killers ( DWM # 277 ) and the Tenth Doctor's comic strip debut The Betrothal of Sontar ( DWM # 365 -# 368 ), by John Tomlinson and Nick Abadzis, where a Sontaran mining rig on the ice planet Serac comes under attack by a mysterious force.

The Sontarans have also appeared as a character in the PC game Destiny of the Doctors released on 5 December 1997, by BBC Multimedia.

All the Sontarans depicted in the television series have monosyllabic names, many beginning with an initial ' st ' sound ( e. g. Styre ( The Sontaran Experiment ), Stor ( The Invasion of Time ), Stike ( The Two Doctors ), Staal ( The Sontaran Stratagem ), and Strax ( A Good Man Goes To War ); exceptions are Linx ( The Time Warrior ), Varl ( The Two Doctors ) Skorr ( The Sontaran Stratagem ) and Kaagh ( The Sarah Jane Adventures )).

The Two Doctors introduced a weapon called the Meson Gun ( as named in the Jim'll Fix It Sketch, A Fix with Sontarans ), a large silver rifle with a red fuel tank in the centre which was used by Group Marshal Stike and Varl in the third episode.

In The Infinity Doctors, the Doctor negotiated a peace between the Sontarans and the Rutan Host when two of them were left trapped in a TARDIS for several hours and got to talking due to their inability to kill each other.

The Sontarans also briefly appear in The Eight Doctors, sent to the Eye of Orion by an agent of the Celestial Intervention Agency to kill the Fifth and Eighth Doctors.

The Rutans only appeared on television in the serial Horror of Fang Rock, in which a single Rutan is encountered, though they are mentioned in some serials featuring Sontarans ( The Time Warrior, The Sontaran Experiment, The Two Doctors, The Poison Sky and The Last Sontaran and Enemy of the Bane episodes of Doctor Who spin off The Sarah Jane Adventures ).

An unspecified incarnation of the Doctor ( but fitting the description of the Eighth ) brokered a peace between the Sontarans and the Rutans in the Lance Parkin Past Doctor Adventures novel The Infinity Doctors.

She left the series in an emotional farewell scene in 1964 at the conclusion of The Dalek Invasion of Earth, but briefly returned for the 20th anniversary special The Five Doctors in 1983 and also appeared in the 30th anniversary charity special Dimensions in Time and ( as a different character ) the independent Doctor Who spin-off film Shakedown: Return of the Sontarans.

These security barriers were breached on occasion by the Sontarans, by manipulating the more technological Vardans, who suborned the Doctor into sabotaging both of these from within ( The Invasion of Time, 1978 ).

The Sontarans are a fictional extraterrestrial race of humanoids from the British science fiction television series Doctor Who, and also seen in spin-off series The Sarah Jane Adventures.

Ross Jenkins in The Sontaran Stratagem describes a Sontaran as resembling " a talking baked potato " but The Doctor sticks up for the Sontarans by saying that, to them, he looks like a pink weasel.

In The Sontaran Experiment, the Fourth Doctor comments that " Sontarans never do anything without a military reason.

The Sontarans depicted in the series have detached, smug personalities, and a highly developed sense of honour ; on multiple occasions, the Doctor has used his knowledge of their pride in their species to manipulate them.

" The Doctor also comments in The Invasion of Time that Sontarans can mass-clone themselves at rates up to a million embryos every four minutes.

The Sontarans also appeared in a skit for the BBC children's programme Jim'll Fix It titled " A Fix with Sontarans ", along with Colin Baker as the Sixth Doctor and Janet Fielding as Tegan Jovanka.

The Sontarans will next appear in the seventh series of Doctor Who, in an episode penned by Mark Gatiss.

The Sontarans appear in the " Doctor Who: The Adventure Games " episode, The Gunpowder Plot.

Big Finish Productions first used the Sontarans for their audio drama Heroes of Sontar-a 2011 Fifth Doctor story.

A Sixth Doctor Lost Story from the mid-1980s, written by Andrew Smith, it features the Sontarans and the Rutans on ninetieth century Earth, tracking down a scientist named Jacob, who escaped through time and space.

The Sontarans have also appeared several times in the Doctor Who Magazine comic strip, both as adversaries of the Doctor and in strips not involving the Doctor.

The Fourth Doctor faced the Sontarans in Dragon's Claw ( DWM # 39 -# 45 ), by Steve Moore and Dave Gibbons, where a crew of Sontarans menaced China in 1522 AD.

In Steven Moffat's short story " What I Did on My Christmas Holidays by Sally Sparrow " ( the basis for the Tenth Doctor episode " Blink "), the Ninth Doctor has a rooftop sword fight with two Sontarans in 21st century Istanbul, defeating them with the help of spy Sally Sparrow, apparently before the events of " Rose " in his personal timeline.

The Sontaran homeworld was destroyed in the future during the events of the Seventh Doctor strip Pureblood ( DWM # 193-196 ) but the Sontaran race pool survived, allowing for further cloning ; the strip introduced the concept of " pureblood " Sontarans not born of cloning.

In " The Pandorica Opens ", some Silurians appear in 102 AD alongside various alien enemies of the Doctor ( including alien Daleks, Sontarans, Nestenes and other species ) to imprison the Doctor in the mythical " Pandorica " in order, as they see it, to save the universe from him.

The Autons returned in the 2010 episode, " The Pandorica Opens ", allying with the Atraxi, Blowfish, Chelonians, Daleks, Drahvin, Draconians, Sontarans, Cybermen, Haemogoth, Judoon, Slitheen, Silurians, Sycorax, Terileptils, Hoix, Roboforms, Uvodni, Zygons and Weevils to trap the Eleventh Doctor.

* Shakedown: Return of the Sontarans-Reeltime Pictures ' second production involved the return of popular Doctor Who monsters the Sontarans and the Rutans.

Sophie Aldred, who had played Ace in Doctor Who, stars alongside the villainous Sontarans and Draconians.

A young Doctor Who fan, Gareth Jenkins, was able to take part in a short adventure titled A Fix with Sontarans with Colin Baker.

She made a guest appearance on Jim'll Fix It in a Doctor Who related sketch alongside Colin Baker's Doctor in 1985 ( A Fix with Sontarans ).

Writing about the last role, Ben Rawson-Jones reported that " Blake's 7 fans were ... pleased to see their beloved Cally pop up in the film as a random solicitor .... Chappell's most notable post-Cally role in science fiction was in the direct-to-video Doctor Who spinoff Shakedown: Return of the Sontarans in 1995.

He also appeared in the Doctor Who spin-off Shakedown: Return of the Sontarans.

The Rutans have made appearances in the Missing Adventure novel Lords of the Storm by David A. McIntee and in Terrance Dicks's New Adventure novel Shakedown ( based on the spin-off video Shakedown: Return of the Sontarans, also written by Dicks ).

The video Shakedown is the only occasion in which Sontarans and Rutans have appeared together on screen.

One novel in the series, Shakedown, was in fact a novelisation of an independent video production that had featured the Sontarans.

The Sontarans are one of the alien races featured in the game.

In 2012, The First Sontarans was released.

Aside from a ritualistic chant in " The Sontaran Strategem "/" The Poison Sky ", they are never seen to engage in any activity that would be considered recreation, though a few offhand comments by Commander Skorr in " The Poison Sky " suggest they do consider hunting a sport ( according to their creator Robert Holmes, Sontarans do have a highly developed artistic culture, but have put it on hold for the duration of the war, while the opening chapter of the novelisation of The Time Warrior, based on Holmes ' incomplete draft, refers to Linx listening to the Sontaran anthem while his spaceship is in flight ).

They have been killed by targeting that location with a knife ( The Invasion of Time ), a screwdriver (" Shakedown: Return of the Sontarans "), and an arrow ( The Time Warrior ).

The Sontarans reproduce by means of cloning rather than sexual reproduction, and thus for the most part are extremely similar in appearance.

In The Sontaran Stratagem, the Sontarans are seen to create human clones by growing them in tubs of green fluid.

The Sontarans made their first appearance in 1973 in the serial The Time Warrior by Robert Holmes, where a Sontaran named Linx is stranded in the Middle Ages.

Other appearances by the Sontarans include the spin-off videos Mindgame, Shakedown: Return of the Sontarans and Do You Have A License To Save This Planet?

In the full-length New Series Adventures book The Taking of Chelsea 426, by David Llewellyn, the Rutans again appear alongside their enemies the Sontarans.

The Rutans were eventually defeated by the Doctor, but had by that time infected a number of the Sontarans as well.
