Moira was one of the major supporting characters in Claremont's Uncanny X-Men run. She worked as a geneticist and was an expert in mutant affairs. She was romantically involved with Professor X. She would eventually found a foundation center on Muir Island centered on mutant research.
Moira MacTaggert received an entry in the Official Handbook of the Marvel Universe Update '89 #4.
Originally, Grant Morrison wanted to use Moira on his run on New X-Men as the team scientist, but she was killed prior to the start of the series. Instead, he used Beast (Henry "Hank" McCoy).
Moira was one of the feature characters in the 2011 two-issue limited series Chaos War: X-Men.
She is one of the main characters in House of X and Powers of X, written by Jonathan Hickman. House of X #2 retconned established continuity, by revealing that she was a mutant all along with the ability of reincarnation.
Fictional character biography
Born Moira Kinross to Scottish parents, Moira MacTaggert was one of the world's leading authorities on genetic mutation, earning her a Nobel Prize for her work. She was the longest running human associate of the X-Men and was Professor Charles Xavier's colleague, confidante, and also once his fiancée, having met and fallen in love with him while they were postgraduates at Oxford University. She ended their engagement for unknown reasons and returned to Scotland. She was married to her old flame, the late politician Joseph MacTaggert which caused delays with her former engagement to Xavier. Joe proved to be an abusive husband; Moira separated from him after he beat her into a week long coma and, as it is implied, raped her, leaving her pregnant. She kept her son's existence a secret, and when Joe refused her a divorce she allowed people to believe she was widowed.
She eventually created a Mutant Research Center on Muir Island, off the coast of Scotland. Moira was forced to contain and imprison her son Kevin, later called Proteus, when he developed reality warping abilities and severe psychosis. One of Moira's goals was to understand human/mutant genetics, in order to cure her son. However, it is suggested that she intentionally married Joseph and gave birth to Kevin in order to produce a mutant with reality-bending abilities.
Moira's connection to the X-Men began long before the team formed. The silent partner in the founding of Xavier's School for Gifted Youngsters and co-creator of Cerebro, Moira assisted Xavier in helping the young Jean Grey recover after the traumatic triggering of her mutant abilities.
Moira was a kind woman who took to helping humans and mutants alike. She rescued a young Rahne Sinclair (Wolfsbane) from an angry mob, and adopted the girl. She even attempted to treat Xavier's son, a mutant known as Legion who suffered from multiple personality disorder. When a confused, traumatized Cable first arrived from the future, he washed up in Scotland unable to speak English, and it was Moira who stood up for him against an angry mob. Taking him back to Muir Island, he scanned her mind and learned English in the process, as well as the truth about her son, and promised to keep her secrets. She taught him literature and the customs of the time and introduced him to Xavier. They became close friends ever since, being the first kind person Cable met in the present timeline, her later death devastating him enough to leave the X-Men. When Magneto was reduced to infancy, he was entrusted to Moira's care on Muir Island, where she altered his genetic code in an attempt to keep him from reverting to villainy.
Involvement with the X-Men
Moira appeared at Xavier's call to act as "housekeeper" for the team while they were on missions (a position that required her to demonstrate her proficiency with an M16 rifle against a demon within hours of her arrival). Though each of the X-Men formed some sort of relationship with the "Widow" MacTaggert, Moira and Sean Cassidy (Banshee) hit it off immediately, forming an on-and-off relationship that would last for the remainder of her life. Proteus' escape and eventual destruction at the hands of Colossus and the X-Men left Moira in a position of ethical compromise again: though Banshee stopped her from cloning her son, she saved his genetic structure on disk to allow herself the future option of bringing him back.
After finding out that her foster daughter, Rahne, was a mutant, Moira was the catalyst for change. She talked a discouraged Xavier into opening his school to the next generation of New Mutants, with Rahne becoming an initial member. She was also an integral part of the support for the X-Men and the New Mutants, providing medical aid including cloning Xavier after the Brood attacks, transferring his mind into a new body and restoring his ability to walk after a Brood embryo nearly killed him.
With the apparent death of the X-Men, Moira and Banshee formed an alternate team based from Muir, and carried on as the leader of the team without him when his duties with the X-Men called him away. Her behavior became unpredictable, her temper impressive, and her decisions harsh and unforgiving as she displayed behavior that made all who knew her suspicious. On Muir, she began to pit her charges against each other in an arena in merciless battles, supposedly allowing her the opportunity to study mutants in action.
Moira and her islanders were involved in the return of Proteus due to the influence of Advanced Idea Mechanics. This was a four-part story in 1991, that ran through that year's annuals for the New Warriors, X-Force, New Mutants and X-Factor. The Shadow King, the corrupting entity behind the island, allowed the Islanders to act heroically in defense of innocent lives.
Eventually, the entire population of Muir Island was identified as being possessed by and mentally corrupted by Shadow King, pitting the Islanders against the combined forces of the X-Men and X-Factor before Xavier freed them from his control.
Moira's alteration of Magneto did not go unnoticed indefinitely. Enraged when he discovered Moira had tampered with his free will, Magneto took Moira captive and forced her to perform the procedure on half of the X-Men, turning them against their teammates. While Moira's alterations worked, it was revealed that, due to mutants' powers requiring their body chemistry to operate in a specific manner, use of a mutant's powers would cause them to automatically resist the 'programming' and reverse the effects of the procedure, so anything Magneto had done was of his own free will. While hostage on Asteroid M, Moira witnessed Fabian Cortez draining Magneto of his powers and manipulating him into placing him as his right hand. Though Cortez fled, it was an observation that would eventually put Moira back in the hands of the Acolytes. Back on Earth, Moira was unable to accept her betrayal of her surrogate family and her own infallibility, and fled the X-Mansion, with Banshee in pursuit.
Excalibur and the Legacy Virus
When a mysterious virus began attacking the genetically engineered mutate population of Genosha, Moira volunteered her services as a geneticist and was forced to watch as the former slaves were decimated by disease. Returning to the X-Mansion, Moira found Illyana Rasputin suffering from the same illness, later identified as the Legacy Virus. Moving back to Muir Island after the girl’s death, Moira became the key figure in working for a cure to the disease (during this time, she also worked on curing Wolfsbane's artificial bond with Havok).
The European superhero team Excalibur took up residence on Muir Island after assisting Moira. She had been attacked by agents of Mister Sinister who was seeking the genetic information on her son. Moira became an official member of the group, acting as their medic, team mother, and morale officer. An information leak revealed her to be the only human infected by the Legacy Virus—a bizarre turn of events possibly caused by her long exposure to the infected on Genosha, her autopsy of Illyana, or some susceptibility because she gave birth to a mutant. It was later established that Moira is in fact a mutant. Despite these events, she maintained a strong outlook on life, helping to maintain discipline, reduce tension, and increase the team's effectiveness throughout Europe. She convinced the team to stay behind when Onslaught emerged, telling them they might be needed if other heroes fell.
Conferring with the X-Men's Beast did not result in appreciable progress. Locking herself in quarantine in a final attempt to cure the virus without endangering any of her teammates, Moira found her attempts foiled by her foster daughter, Wolfsbane, and Douglock. Wolfsbane originally leapt through the closing doors of the laboratory as the quarantine took effect. She soon found herself a willing assistant to her foster mother's work. Douglock later caused much unintentional damage, his judgement clouded by personal feelings for Wolfsbane. Moira takes time off from her research to attend the bachelorette party and the wedding for her friends Meggan and Brian Braddock.
Moira did eventually find a cure for the disease, when the terrorist Mystique manipulated her research to force the virus to target only humans. Mystique, partly assisted by Sabretooth, then destroyed Muir Island, de-powered Wolfsbane with the power nullifier once developed by Forge, and brutally injured Moira. Bishop, Wolverine, and Rogue attempted to save Moira's life. Despite Rogue's powers temporarily granting her medical knowledge, she was unable to do so. Moira clung to life long enough to mentally transfer the information to Xavier in one final embrace between the former lovers. Xavier nearly went with her into death, but Jean Grey and Cable intervened on the astral plane, talking him down. She died in the X-Men's jet, far above the Atlantic Ocean, and was later buried in Scotland. It was later established that unbeknownst to everyone, Moira had actually faked her death by using a Shi'ar golem to impersonate her and die in her place.
Despite being aware of Moira's death being a ruse, she still had an effect on Xavier. A psychic representation of Moira was seen as an active portion of Xavier's consciousness as he worked on rebuilding Genosha.
Moira is next seen in the afterlife, in which she, Mockingbird, Gwen Stacy, and Dead Girl assist Doctor Strange in battling a being known as the Pitiful One. Moira finds herself more interested in the book club she formed with Mockingbird and Gwen Stacy then in battling evil.
X-Men: Deadly Genesis
After the events of M-Day and upon the reawakening of Vulcan, significant portions of Moira's history with Xavier and the Original X-Men are called into light. While in the rubble of Muir Island, Moira appears to Banshee which at this point he believes to be her spirit. Moira completely ignores him and leads him to an old stockroom, where Sean finds old, important notes from the Professor which reveals that during the early years of Xavier's Academy, Moira founded and ran a secondary facility not far from the Xavier School, in which she had her own students; youths whom she took out of bad situations and adopted as her wards, training them in their abilities without the highly militant regimen of Charles' X-Men.
When Krakoa captured the original X-Men, it was Moira's students whom Charles went to first—not the second team of Wolverine, Storm, Banshee, Colossus, Nightcrawler, Thunderbird and Sunfire as it was originally believed—putting them through the psionic equivalent of boot camp and allowing them to believe they were being trained over months as X-Men. Charles took them from Moira's care immediately.
Moira's students—Vulcan (Gabriel Summers, the lost brother of X-Men Cyclops and Havok), Petra, Darwin, and Sway—were apparently all killed, and Xavier suppressed even the memory of them from his own students, to keep them from going back to save them. Only Moira's project tapes, one made directly after the event before Xavier could suppress the memories, and an abandoned research center remain as clues.
During the "Chaos War" storyline, Moira MacTaggert returns from the dead alongside the fallen X-Men members after what happened to the death realms. After escaping from Carrion Crow, the group discovers that Moira has been possessed by Destiny's ghost. However, this comes under question, given that she had faked her death.
House of X
In 2019's House of X, it is revealed that Moira is actually a mutant who possesses the power of reincarnation, starting her life again in the past after her death, possessing her full memories of her prior lives. She is also revealed to be alive, having faked her death at the hands of the Brotherhood by using a Shi'ar Golem which impersonated and died in her place. She has experienced ten lifetimes, with different outcomes:
The Lives of Moira MacTaggert
Life 1 Moira Kinross was born to powerful Scots nobleman Lord Kinross and when she turned 13, her mutant ability manifested, but due to her passive power, there were no signs indicating that she had become a mutant other than a strong, temporary fever. Living a simple life, Moira meets Charles Xavier, but he passes through without them forming a bond. She later marries a man named Kenneth Cowan and has three children: twin boys Callum and Dean, and a girl named Abigail. Kenneth dies when Moira is 68 years old, and she passes away from congestive heart failure at age 74.
Life 2 Her second life began in utero, having already become fully sentient and possessing a perfect recollection of her prior life when she turned 13, which is when her powers first manifest. This allowed Moira to appear intellectually gifted, and she was pushed in the direction of academia. She didn't fight her parents' intentions, since she intended to understand her true nature. After she verified that she wasn’t suffering from psychosis or a disorder, and having living through one life with Kenneth and learning all his faults, she makes a point not to fall in love with him when they met. She enrolls at Oxford at age 16, becomes a biology professor at 20, founds the Muir Research Institute at 31 and at 44 she finally deduced she was a mutant after seeing Charles Xavier coming out as one on television. She boards a plane to the United States of America in order to meet him, however, the plane crashes before reaching its destination, killing Moira.
Life 3 Beginning her third life in utero again, Moira made a point of finding Xavier earlier. She meets Charles Xavier when they were both at Oxford University, however she becomes turned off by his arrogance and a thinly veiled god complex. So she instead devotes her life to finding a cure for mutation, which she compared to cancer. Moira founds again the Muir Research Institute, and at 36 she identifies the X-gene. Just when it appears Moira had rid herself of her reincarnation powers,the Brotherhood of Evil Mutants attack the Muir Research Institute. Able to see the future and Moira's ability, Destiny decides to stop her and the cure. With the Brotherhood, she wipes out the lab and shared with Moira the knowledge that the humans would always try to destroy mutants. Before Moira dies, Destiny warns her that if she pursues a cure in future lives, she will find her. She also tells her that she sees Moira living 10, perhaps 11 lives at most. Another complication is if Moira dies before her powers manifest at 13, she won't reincarnate. By Destiny's request, Moira is then killed by being slowly burned alive by Pyro so she would always remember what this slow and painful death feels like.
Life 4 In her fourth life, reconsidering the positive nature of mutants and Xavier himself, Moira throws herself into studying the human-mutant dilemma. She meets Xavier and goes on to fall in love with and marry him, with the couple establishing the Xavier School for Gifted Children. She, Xavier and the X-Men fight for the mutant cause for years, but at age 55, Moira is killed by Sentinels. That ultimately means Destiny's vision was right as she warned Moira that humans would always try to exterminate mutants.
Life 5 Now choosing aggression as a response to the violent tendencies of humanity, Moira runs away from home at 13, to encounter Xavier a full decade earlier than when they're supposed to meet. Not wasting any time, Moira opens her mind to Xavier so he can see how his dream fails in her past lives. The mind-reading radicalizes him, forcing the duo to form the mutant nation of Faraway instead of a school. It seemed mutants were finally safe from humanity. Yet, Boliver Trask's adaptive-learning Sentinels still make their way there, and Moira is initially injured in an attack when she was 43 and dies a year later during a genocide.
Life 6 In her sixth life, Moira discovers the true threat to mutants are not Sentinels or Nimrod, but rather the next step of human evolution. It turns out that while mutants are the natural evolution response to Humans, they are not the next evolutionary step for Them, and they never will be because Humans will use the Sentinel technology to extend their life and when they reach an evolutionary stagnation, they will overtime integrate themselves with the Sentinels, creating in the process a genetically engineered new species, the Post-Humans (homo novissima), an artificially blue-skinned humanoid race that will rule the Earth and bring mutants nearly to extinction, one thousand years in the future. The last surviving mutants are kept captive in preserve areas. Moira and Wolverine are among them because they were able to survive on each other's blood. One of the Post-Humans, the Librarian, comes to them and reveal that due to their techo-organic nature, it allows them to be more readily absorbed by the Phalanx in a process known as Ascension and achieve godhood, which could bring Post-Humans dominion over time and space. The Librarian intends to send Moira and Wolverine to another planet to prevent Moira from dying and use her knowledge of how humanity overtook mutantkind by using science to make mutants and mutant powers obsolete against them in her resurrection. However, the Librarian underestimated Wolverine who manages to kill him and afterwards, with Moira's consent, kills her too.
Life 7 With the knowledge that the Trask Family is responsible for creating the Sentinels and after learning about the Ascension, Moira spends her seventh life eradicating the Trask bloodline. Bolivar, Donald, Gwyneth and Simon Trask are systematically murdered over the span of a decade, with Moira even taking out their children for good measure. But when she thought she had successfully eliminated the potential for Sentinel creation, Moira lost all hope when she sadly discovered Sentinels were still being created. She finally understood that Mutantkind’s fall is the "Inevitable Truth" as the Artificial Intelligence is unavoidable since its a discovery and not a creation. This realization radicalized her as Sentinels killed her again.
Life 8 Abandoning Xavier's peaceful dream to foster a safe future for mutants, Moira seeks out Magneto instead. Presenting Magneto with tales of her past lives and his future failures, Moira convinced him to join her. Together they conquered America, establishing the House of M. Eventually the Sentinels rise and the War of M began with Magneto dying during the war and Moira dying later while trying to escape from prison.
Life 9 Though eventually a failure, the life-defining decision Moira made to turn to Magneto, did validate her radical approach to beat humanity through force. Magneto was simply not enough. To that end, in her ninth life, Moira woke Apocalypse from his slumber early. Forming a powerful union that leads to the creation of the X-Men, they destroy their two strongest opponents, Xavier and Magneto, gather their Four Horsemen and launch the Apocalypse War. The war provokes a reaction from humanity in the form of the Man-Machine Supremacy, an alliance between humans and machines which culminates with Nimrod becoming online for the first time. One hundred years later, most mutants have been driven out of the solar system as the war still rages. Apocalypse's forces split into two teams, as one group attacks the Temple of Concordance, while another group heads into Nimrod's vast archives to extract vital information about its origins. Once the info is gathered, Apocalypse sends Wolverine away and stays behind to take on Nimrod once it realized that the archives were being raided. Wolverine's destination is revealed to be a container that holds Moira MacTaggert in stasis for over 16 years. With the data embedded into Moira through a techno-organic interface designed by Apocalypse himself, she now knows how and when Nimrod was first brought online, but for that information to actually be useful, Logan kills her.
Life 10 Moira’s tenth life occurs in the current iteration of the Marvel Universe. She again meets Xavier and allowed him to read her mind to learn everything her lives had entailed. Later while working on a cure for the Legacy Virus, she secretly used a Shi'ar golem to fake her death when Mystique and her Brotherhood of Mutants attacked the Muir Island facility, but she eventually revealed herself to Xavier and Magneto. She then took residence in "No-Place" a blackout zone within the newly sovereign, living island nation of Krakoa, and is using the information from her previous lives to work with Xavier and Magneto to save mutants from humans and machines.
Powers and abilities
For decades, Dr. Moira MacTaggert was depicted as a baseline human with the normal human strength of a woman of her age, height, and build who engages in moderate regular exercise. However, in the 2019 storyline, "House of X", Moira was revealed to actually be a mutant with the ability to reincarnate herself upon death, reverting back to the moment of her initial conception with all the memories she experienced in her previous lifetimes from as early as in utero. This allows her to manipulate the course of history by changing her own actions and thereby affecting people and circumstances that result from her presence. Her lifetimes have armed her with significant experience, including expertise in the fields of anthropology and genetics, firearms mastery, and leading various mutant survival movements until their eventual downfall.
According to Destiny, Moira's reincarnation cycle is finite. When she encountered Destiny during her third life, she was informed that she had "10, maybe 11" lives in total, noting that if Moira were to die before her mutant power manifested at the age of 13, the reincarnation cycle would end.
Her x-gene is also undetectable during her life, providing the ultimate camouflage to mutant sensors and detectors which will see her as a baseline human. Telepathic intrusions on her mind will only see the memories of her current lifetime, however, telepaths can see all her lives' memories as long as she allows it.
Age of Apocalypse
In the 1995-1996 "Age of Apocalypse" storyline, Moira is the wife of Bolivar Trask, and head of the London-based Human High Council. As resistance to Apocalypse's reign, Moira and her husband designed the Sentinels and armed the human resistance with an impressive weapons array. Their main focus was a plan to destroy Apocalypse's forces in their North American positions, even though this would mean the deaths of many innocent civilians that had not yet escaped the country. The tyrant however, backfires by activating his Sea Walls, slaughtering the Council and those within the Sea Walls reach.
Age of X
In the Age of X reality, Moira is the step-mother of Legion (stating that his father had been killed in a bombing in Israel) and therefore the only human living on Fortress X. It was later discovered that she was actually one of the multiple personalities of Legion, created as a "Psychic Anti-body" in order to protect Legion from Doctor Nemesis' actions on David mind, as he and the X-Club were processing the deletion of the personas in order to stabilize David's psyche. Her power is so immense that when she was discovered by Xavier, she was able to defeat him and established the Age of X reality, where mutants were besieged into the Fortress X, everyday attacked by the waves of soldiers of the Human Coalition and used the personalities inside David's mind along with the mutants of Utopia to fill this new world where David would be happy and seen as a hero, as part of the Force Warriors, the protectors of the Fortress, who erected force walls around the citadel every day. Even memories were rewritten, and a background was created. The telepaths and a few others mutants who were able to retain knowledge about the true universe were kept in the X-Brig, considered as mutants too dangerous for the community, but their imprisonment was because they might use their powers to reveal the truth. She also posed as the AI X, so she could use communication worms and sensors to communicate with and monitor the residents of Fortress X. When her victims slowly understood that this reality wasn't their one, she manipulated both Danielle Moonstar and her Moonstar Cadre in order to make them to stop any further discovery. Eventually her depiction was revealed and Legion absorb her. Later she offers to make a better world for David, but he declines her offer. During the Lost Legion story Moira's powers were the main target of another personality of Legion and at the end she was seen inside David's mind cursing Xavier.
Reichminister of Genetics Moira MacTaggert, who hails from a reality in which Earth is dominated by Nazis, is featured in Excalibur #10 and 11 when she is brought into Earth-616 by the actions of a confused Widget. Making the trip with her is her personal bodyguard, a Nazi Callisto and Moira's personal train, powered by an alternate Lockheed. It was also hinted that this Moira was behind the Super Team Lightning Force (a Nazi version of Excalibur). Moira's violent actions ultimately result in Excalibur team being sent on a long and arduous cross-dimensional trip.
House of M
In the House of M reality, Moira MacTaggert was declared a criminal for attempting to cure her son Kevin of the mutant gene and his psychosis. King Magneto's mutant supremacy saw this as an act against mutantkind, and Sentinels were dispatched to destroy Muir Island and capture Moira. Though Moira escaped, Kevin was also freed, sending him on a gruesome killing spree that was attributed to Moira as failed experiments, as she chases him across the globe. When the reality-hopping Exiles caught Proteus's attention, Moira emerged from hiding to warn them about her son, who was intrigued by their presence and desired to ruin the realities they attempted to fix. When he attacks the team, Moira shot him, exposing him to the metal that was his deadly allergy and only weakness, forcing him to find a new body. Unsurprisingly, he chose to possess his mother, and rather than allow her son to possess her and use her against them, Moira commits suicide.
On the world of the Sons of Iron and Daughters of the Dragon, the New Exiles face a squad of alternate 'core X-Men' who are loyal to Lilandra. These X-Men include an alternate version of Moira MacTaggert who is not married on this world or is going by her maiden name, Kinross. Moira's codename is Hypernova and her powers are energy blasts. It is not known whether she is a mutant on this world or has gained powers through another method.
In the Ultimate Marvel continuity, Moira MacTaggert is the ex-wife of Charles Xavier, and their son David MacTaggert is Proteus. This version of Moira needs two crutches in order to move around. Moira runs a school/hospital for sick mutants, and assists in the Xavier Institute from behind the scenes. She does this even though Charles left her to join Magneto's dream of a mutant society, abandoning her to raise their mentally ill child on her own. When Proteus escapes and begins body hopping, Moira calls in the X-Men for assistance. After murdering hundreds, Proteus is seemingly crushed to death under a car.
Later, the X-Men learn that Moira has been funding her hospital by producing and selling "Banshee", a lethal and addictive Mutant Growth Hormone which amplifies mutant powers, made from the genetic material of Wolverine. When Wolverine attempts to destroy her Banshee supply, Moira attacks him with the previously unknown mutant ability to emit a deafening sonic cry. Wolverine quickly defeats Moira and leaves her to die in the exploding hospital, but she is later shown to have somehow survived when Quicksilver finds her emerging from the smoldering ruins. Her ensuing conversation with him implies that she is now in league with Quicksilver.
In other media
- Moira appears in episodes of X-Men, voiced by Lally Cadeau. She first appeared in the episode "The Cure", where supposedly knew a doctor with a cure for mutants. The next episodes were "The Phoenix Saga", where she was worried about Professor Xavier's control over his mind. In the "Dark Phoenix Saga" she was working to help Jean Grey be freed from the Phoenix. Then, the next appearance was in "Proteus", in which she revealed to Xavier that Proteus was her son. Here she seems to fill the function of Gabrielle Haller, an old lover of Charles and mother of his son, the powerful but disturbed psychic boy David. Her next appearance was "The Phalanx Covenant, Part 2", when she was infected by Phalanx. Her last appearance was in "Graduation Day", when she and Beast debated on how to contact Lilandra Neramani to help Professor X.
- In Marvel Anime: X-Men, the character Yui Sasaki (voiced by Yoshiko Sakakibara in the Japanese version and by Gwendoline Yeo in the English) is introduced as that version's Moira, as she slightly bears resemblance to her. Like Moira, Yui is a geneticist and has a relationship with Professor X when she still owns the Sasaki Institute in Japan. But unknown to Charles, she is the mother his son with her name Takeo Sasaki. Under the misguided idea of trying to help suppress mutant powers, she entered a partnership with the U-men; they would harvest mutants DNA for a cure for mutancy. In exchange, she gave them a mutant detection device uninhibited by her own Cerebro-jammer. Yui's plans start falling apart, when her serum starts accelerating mutations instead of suppressing them. This leads both the X-Men and the Inner Circle to Japan. Unknown to her, Mastermind was posing as her lab assistant, and was working on trying to brainwash Takeo. Thanks to Armor and Professor X's help, they let Takeo pass away in peace.
- Moira is played by Olivia Williams in brief appearances in the feature film X-Men: The Last Stand. She appears on a video talking about the ethics of using mutant powers, such as transferring the mind of a dying man into the body of a patient with no higher brain function. She is later seen seated next to Beast at the memorial service for Xavier. After the film's ending credits, she appears again attending to the brain-dead patient, who suddenly speaks to her in Xavier's voice.
- Rose Byrne plays Moira in X-Men: First Class. She is a CIA agent working to uncover the mysterious Hellfire Club. This version is depicted as an American instead of being Scottish. During her investigation in Las Vegas, Nevada, she manages to infiltrate a meeting by stripping down to her underwear to blend in with the strippers in which she discovers mutants intimidating a military officer. After the incident, she seeks help from recently graduated professor Charles Xavier, due to his affinity for research in the subject of genetic mutation. Moira eventually learns that Charles and his foster sister Raven are mutants themselves with Xavier demonstrating his mind-reading while Raven reveals her shape-shifting. She later becomes the liaison to the team and assists the newly formed X-Men in preventing Sebastian Shaw from starting a nuclear holocaust between the Soviet Union and the United States during the Cuban Missile Crisis. At the climax, she is indirectly responsible for Xavier's paralysis as she fires the bullet which Magneto accidentally deflects into Xavier's spine. In his rage, Magneto almost kills Moira by strangling her with her dog tags until Xavier makes him realize he caused his friend's injury. At the film's end, Xavier erases her memory of the events with Shaw and Magneto while kissing her. This was in order to keep the school for mutants that he has opened during the crisis a secret.
- Byrne reprises her role in the film X-Men: Apocalypse. Still having a large interest in mutant activity, she investigates a cult in Egypt that was formed upon the existence of mutants being revealed to the public, and ends up inadvertently and unknowingly causing Apocalypse to awaken from his sleep. Charles decides to visit her and take her to the X-Mansion to find out more information and because he misses her. It is here where she tells Charles she has a son, although she is divorced from the boy's father. While at the X-Mansion, the team are attacked by Apocalypse and his new Horsemen, and Moira becomes drawn into the conflict, acting as the pilot to the team's aircraft when they go to confront Apocalypse. At the end of the story, Charles restores Moira's memories back to her and restarts his relationship with her.
