The first volume, The Secret Service (2012–13), written by Mark Millar and illustrated by Dave Gibbons, is set over the course of three years. Gary London is recruited by his uncle, Caractacus "Jack" London, to work for Kingsman, the British Secret Service. Gary is put on an extensive three-year training course, performing various assassinations and apprehending a Colombian drug lord. While investigating a series of celebrity kidnappings perpetrated by Dr. James Arnold, a very wealthy cellphone entrepreneur who plans to use a satellite signal to make the poor of humanity slaughter each other to solve the overpopulation problem, London is killed by Arnold for sleeping with his girlfriend, unaware of his Kingsman allegiance. Horrified by his uncle's death, and learning that Arnold is supported by higher-level members of Kingsman, Gary recruits his fellow trainees to an assault mission on Arnold's base, hidden inside a mountain in Switzerland.[9][10]
After ambushing and battling Arnold's troops, freeing the captured celebrities, including Pierce Brosnan, Patrick Stewart and David Beckham, Gary engages in a fist fight with Arnold's henchman and former Kingsman agent Gazelle, and leaves to confront Arnold. Arnold activates the satellite signal and waits for the people to slaughter each other, but instead, due to one of Gary's colleagues having changed the frequency, people worldwide begin to have sex with one another. Gary then kills a confused Arnold.
In an epilogue, Gary reads his uncle's will, revealing that two-thirds of Jack's estate will go to the Royal National Lifeboat Institution and the British Heart Foundation, the final third going to Gary's mother, informing Gary to take good care of his gadget-laden car, or he will "come back and bloody haunt him." As Gary reports to Kingsman Headquarters, Sir Giles briefs him about a mission that concerns "trouble in Moscow".[11]
The Red Diamond (2017–18)
The second volume, Kingsman: The Red Diamond, written by Rob Williams and illustrated by Simon Fraser, was released through Image Comics in September 2017, taking place over the course of one week. After knocking out Prince Philip following saving him from a group of Greek terrorists ignorant of the fact that the prince is Greek himself, Gary "Eggsy" Unwin (retconned to have the same surname as his film counterpart) is put on a week-long leave of absence. Returning to Kingsman headquarters to retrieve a pill to treat his little brother Ryan's norovirus, an alert comes in from the South African Secret Service (SASS) regarding an encrypted message sent to a wanted hacker named Alias at Times Square in Manhattan. As the only agent present, Eggsy is sent out on a rocket to find Alias before the SASS.[12]
Upon finding him, Eggsy is confronted by Kwaito – a SASS agent, and Ingot – a Red Diamond agent. Upon restraining Alias, Alias explains that he was trying to shut down the servers in the financial district to protect them from a virus released by the Red Diamond's agent. Ingot kills Alias and makes his escape, trapping Eggsy and Kwaito. Once he leaves, the virus is unleashed worldwide, causing a global blackout. The Prime Minister of Britain receives a Betamax tape from the head of the Red Diamond, self-made South African mining magnate Jakobis Du Preez, who explains his plans to replace the world's physical money with gold and jewels; in a separate tape, he invites the "Kings and Queens of the new material world" to a remote location in the Hunan Province, China.
Eggsy and Kwaito independently go undercover to the event only for Du Preez to set off a bomb to get rid of "the competition". Retrieving a map to the Red Diamond base from Ingot and crashing into a forest with Kwaito, Eggsy and Kwaito make love. Later finding civilization and a phone to use, Eggsy discovers that Kwaito has stolen the map. Having memorized it, Eggsy travels to Guam where he is reunited with Kwaito. Making their way inside the base, the pair find Du Preez sitting naked on a hill of jewels and gold bars. Du Preez explains that they cannot kill him lest a fail-safe he attached to his heart open the airlocks and kill everyone. After a confrontation with Ingot, Eggsy shoots Du Preez with a poisonous spy-dart which will slowly kill him, and makes his escape with Kwaito and Treeman, a hacker held captive by Du Preez. While fleeing, Treeman gains access to a Red Diamond computer and uploads an override to delete the Red Diamond virus. In the epilogue, a ceremony is held in Eggsy's honour. Several esteemed guests are invited—including Prince Philip, who wants to apologise and shake Eggsy's hand. However, Eggsy instead takes his family and Kwaito to his favourite pub.

^Phegley, Kiel (10 January 2012). "Millarworld Exclusive: Inside "The Secret Service"". Comic Book Resources. Archived from the original on 12 January 2012. Retrieved 12 January 2012. Mark Millar: "This education of a 21st Century super-spy forms the structure of the story. I can't give too much away because Matthew Vaughn and I co-conceived the thing with Dave [Gibbons], and Vaughn is literally right now writing the screenplay of the movie, so we're on a non-disclosure agreement for a little while yet. But basically, if I had to say anything else about it, I would say that this is our version of S.H.I.E.L.D. or U.N.CL.E. or any of those brilliant super-spy concepts, but seen through that skewed perspective we brought to superheroes in 'Kick-Ass.' It feels very, very fresh. I don't think there's ever been a comic like this and all three of us are very excited about it. I've wanted to work with Dave since I was sixteen [so] it had to be something big."
