Mister Sinister
Mister Sinister is a supervillain appearing in American comic books published by Marvel Comics. Created by writer Chris Claremont, the character was first mentioned as the employer behind the team of assassins known as the Marauders in The Uncanny X-Men #212, and later seen in silhouette in The Uncanny X-Men #213, with both issues serving as chapters of the 1986 "Mutant Massacre" crossover. Mr. Sinister then made his first full appearance in The Uncanny X-Men #221, with artist Marc Silvestri designing his visual look.
A villain who usually prefers to act through agents and manipulation, Mr. Sinister was born Nathaniel Essex in Victorian London. A human scientist, Essex is inspired by the work of his contemporary Charles Darwin and becomes obsessed with engineering humanity into a perfect race of superhumans. As he learns about mutants, Essex encounters the mutant villain Apocalypse. The two become allies and Apocalypse uses alien Celestial technology to transform the British scientist into Mr. Sinister, an ageless man with super-powers. Later on, Sinister increases his power through self-experimentation. In the modern day, Sinister develops a great interest and protective attitude towards the mutant heroes Cyclops and Jean Grey, believing their DNA can create the ultimate mutant. This and other factors lead him to have repeated clashes with the X-Men and related teams. Through clones, Sinister has managed to cheat his death repeatedly and even acquire a mutant gene. Later, the Krakoan Age storyline revealed that the original Mr Sinister was one of [|several clones] of the original Nathaniel Essex, each with a distinctive scientific specialism and playing card theme.
Making frequent appearances in the X-Men comics and related spin-off titles, Mr. Sinister has also featured in associated Marvel merchandise including animated television series, toys, trading cards, and video games. IGN's list of the "Top 100 Comic Book Villains of All Time" ranked Sinister as #29. The character was exposed to a wider audience with his television debut on X-Men: The Animated Series voiced by Christopher Britton, as well as an appearance in Wolverine and the X-Men voiced by Clancy Brown.
Publication history
Writer Chris Claremont conceived Sinister as a new villain for the X-Men. Having felt "tired of just going back to Magneto and the Brotherhood of Evil Mutants and the same old same old" Claremont recalled:Mister Sinister was first mentioned by the assassin Sabretooth as the employer behind the team of assassins known as the Marauders in The Uncanny X-Men #212, which was part of the 1986 "Mutant Massacre" storyline, in which Sinister ordered the Marauders to kill the Morlocks living beneath New York City. In the next issue, drawn by Alan Davis, Mr. Sinister is first glimpsed as a generic silhouette when the telepathic X-Man Psylocke scans Sabretooth's mind. Mister Sinister appeared unobscured for the first time on the opening splash page of issue #221, drawn by Marc Silvestri. The character is one of the major antagonists in the 1989 "Inferno" storyline, where it is revealed he created the character Madelyne Pryor, estranged wife of Scott Summers, by cloning Scott's former lover Jean Grey, who was believed dead at the time. Sinister sent Madelyne into Scott's life in the hopes that the combined DNA of Grey and Summers would result in the birth of a powerful mutant. Soon after "Inferno", Sinister is also revealed to have manipulated Cyclops' life since early childhood and who at times has influenced his behavior from afar. After a battle with the X-Men and X-Factor, the villain is apparently destroyed by Cyclops' optic beam, leaving behind only bones.
Months after his apparent death, backup stories by Claremont published in the reprint series Classic X-Men #41–42 detailed the role Mister Sinister played in Cyclops' early life at an orphanage in Nebraska. The stories feature a boy named Nate who is roommates with the young Scott Summers. Despite Scott saying he does not particularly like Nate, the boy appears to be unhealthily attached to him and is aggressively protective, blocking Scott from having other friends. Claremont intended Nate to actually be Mister Sinister, revealing this was his true form and the armored villain was an illusion he used to threaten others. However, Claremont left the X-Men comics before this origin was revealed to readers. Fans later considered "Nate" to be Sinister in disguise as a boy, whereas his adult, armored appearance was his true form. The 2009 series X-Men Forever showed an alternate timeline, beginning at roughly the same point where Chris Claremont left as head writer of the X-Men years before. Written by Claremont, the series revealed how he would have continued the stories and what revelations he would have made about different characters. The 2010 sequel series, X-Men Forever 2 features Mr. Sinister as a character who is over a century old yet still physically an adolescent boy, using a robot called Mr. Sinister to act as a proxy.
Despite his apparent death in the "Inferno" storyline, Sinister appeared again in X-Factor in 1992, now leader of the Nasty Boys team and displaying the ability to regenerate from damage. He played a major role in the 1992-1993 crossover storyline "X-Cutioner's Song", unwittingly helping to unleash the Legacy Virus on the world. In X-Men #22-23, Sinister reveals his seeming death was a "ruse" so he could retreat rather than fight the combined X-Men and X-Factor teams. The same story depicts Sinister willing to protect Cyclops from other villains.
By 1994 Mister Sinister was popular enough that Chef Boyardee used him to advertise its pasta. In X-Men Annual 1995, flashbacks reveal Sinister living in Los Angeles in the 1930s as "Nathan Essex" and depict him as an adult man during that era. In the 1996 limited series The Further Adventures of Cyclops and Phoenix, writer Peter Milligan establishes Sinister's origin, revealing he was originally a Victorian-era scientist named Nathaniel Essex who later gained superhuman powers from Apocalypse, thus abandoning Claremont's idea that he was an immortal trapped in the form of a child.
The 2006 mini-series X-Men: Colossus Bloodline revealed that Mr. Sinister's powers were weakening and he hoped to restore them. Before he can restore his full power, Sinister is killed in New X-Men #46. The same year, a contingency plan in X-Men: Legacy #214-215 involves him attempting to take a new host body, but fails. In X-23 #5-6, another resurrection contingency plan led to the creation of Miss Sinister and to Mr. Sinister's mind inhabiting a clone body of himself. In The Uncanny X-Men #544, it is revealed that Sinister is now an entire colony of Sinister clones co-existing, each with minor differences. In subsequent battles, the leader Sinister and other clones were killed, only to be replaced by new clones with the same consciousness and improved genetics. The community of Sinister clones is destroyed in The Uncanny X-Men #16. In issue #17, reveals that one copy of Mr. Sinister's mind survived, however, planting himself in the mind of X-Men public relations manager Kate Kildare. The surviving Sinister mind kills her and creates a new clone body to inhabit.
In the 2019 mini-series Powers of X, it is revealed that several years before the present-day, one of the clones Sinister created possessed an X-gene, making him a mutant like the X-Men. This mutant Sinister assumed leadership of the community of Sinister clones and seems to be the surviving version who operates today. The same mini-series involved Mr. Sinister joining the new mutant community of the island Krakoa, and joining its ruling Quiet Council alongside Magneto, Professor X, Apocalypse, and others.
The 2023 series Immortal X-Men established that the original Nathaniel Essex was murdered by Sherlock Holmes / Mystique in 1895. Before his death he created four clones to research paths to Machine Dominionhood independent of one another, whom Mystique's wife Destiny ensured would survive to adulthood. The clone branded with continued to operate as Minister Sinister, while two others, branded with and respectively, became Doctor Stasis who researched various ways to post-Humanity and Orbis Stellaris who abandoned Earth and ventured into space to research alien technologies. The fourth clone with the was of his late wife Rebecca who became a magical user called Mother Righteous. The male clones were unaware of one another for a long time, and each believed themselves to be the original Nathaniel, with no memory of dying and being cloned. In different possible futures, each had eventually succeeded in ascending to categorical godhood as a Dominion, only to be blocked and had their progress harvested by the A.I. imprint of the original Essex, who thus retroactively brought itself into existence as Enigma, a universal-level godlike intelligence existing outside space and time.
Fictional character biography
19th century
Born in Milbury House in Victorian London, Nathaniel Essex is the son of Admiral Erasmus Essex and Mary Essex. Earning a full scholarship to the University of Oxford, Essex becomes a biologist in 1859 and marries his wife Rebecca. A contemporary of Charles Darwin, Essex becomes highly interested in research regarding evolution and "survival of the fittest." He concludes humanity is undergoing increasing mutation due to what he calls "Essex Factors" in the human genome. After the loss of his four-year-old son Adam due to birth defects, Essex becomes more obsessed with his research in perfecting and improving the human race. Arguing that science is beyond morality, his questionable research methods and ideas lead to suspicion, mockery, and finally ousting from the Royal Society and the scientific community. Angry and bitter, Essex accepts that being a "monster" in the eyes of others may be necessary to achieve his goals.Essex later hires the criminal Cootie Tremble and his gang, known as the Marauders. The Marauders kidnap homeless people off the streets of London as test subjects for Essex's experiments, including a man named Daniel Summers. Two years after Adam Essex's death, Nathaniel Essex learns that some humans are born with mutant genetics that make them superhuman and discovers that one called En Sabah Nur is in hibernation. The Marauders awaken En Sabah Nur who then offers Essex an alliance, believing they have similar goals in perfecting the world and humanity.
Nur then intends to conquer 19th-century England but is confronted by Cyclops and Phoenix, heroes from the future who arrive via time travel. Nur defeats the two heroes, leaving them for Essex to experiment on. Hoping to stop Apocalypse and possibly the origin of Mr. Sinister, Phoenix tells Essex that continuing his work with Nur will lead to worldwide destruction. Sensing truth in her words, Essex releases the heroes and decides to rededicate himself to family, as his wife Rebecca is pregnant again. Meanwhile, Rebecca Essex discovers Nathaniel's imprisoned human test subjects and his lab where he has experimented on the remains of their son. After freeing the prisoners and reburying her son, Rebecca goes into premature labor and her second child dies in stillbirth. Nathaniel then finds Rebecca, who is now dying from blood loss, and asks for forgiveness. Rebecca refuses, saying with her dying breath, "To me, you are... utterly... and contemptibly... sinister!" Following Rebecca's death, Essex continues his alliance with En Sabah Nur, becoming the villain's first "prelate." Apocalypse reveals he has alien technology belonging to the Celestials. With the Celestial machines, Apocalypse subjects Essex to a painful genetic transformation, turning him into an ageless being with chalk-white skin and a form of telekinesis. En Sabah Nur tells the transformed scientist to shed his past identity and choose another, and Essex renames himself "Sinister." Although he claims his humanity is gone, Essex continues to carry Rebecca's photo until 1882.
When Apocalypse demands Sinister create a plague that will wipe out much of humanity, leaving only "the strong" alive, the scientist refuses, arguing that cruelty without purpose is ignorance and the enemy of science. Appreciating Sinister has shown strength through defiance, Apocalypse returns to his hibernation state, promising that when he returns he and Sinister will reshape the world. Following the death of Charles Darwin, Sinister travels to America and assumes the identity of obstetrician "Nathan Milbury", head of the Essex Clinic in New York in the 1890s. There he continues secret experiments on people. He comes to understand more and more that mutants are human beings born with an "X-factor gene" or "X-gene", causing powers, traits, and abilities that often manifest during puberty or trauma. One early test subject is a mutant with a long lifespan named Amanda Mueller. To study how the X-gene may pass on to children in different ways, Sinister arranges for Amanda to marry his former test subject Daniel Summers. On several occasions when Amanda is pregnant, Sinister pays her to feign miscarriage and then secretly bring him the child for study. Seeing great potential in the Summers genetic line, Sinister decides to monitor the family.
Around this same time, Sinister encounters two other mutants traveling from the future: Gambit and Courier. After experimenting with a cell sample from the latter man, Sinister gains complete control over his physical form, allowing him regenerative abilities and shape-shifting, while leaving Courier trapped in the form of a woman. Before the two time travelers leave, Sinister sees evidence of his own surgical techniques on Gambit.
In 1899, Apocalypse emerges from hibernation again and is pleased with Sinister's work, including the development of a deadly techno-organic virus. Sinister then injects the virus into Apocalypse, but it only weakens the villain. As Apocalypse returns to hibernation to heal, he promises to kill Sinister when next they meet. Sinister decides to engineer a mutant who can kill Apocalypse.
