Early Years

19th Century scientist Nathaniel Essex accidentally manages to genetically mutate himself after studying and researching the history of the Egyptian mutant known as En Sabah Nur who was also known by many as Apocalypse, while he was experimenting experimenting on the X-Genes. He was somehow thinking about his deceased wife and son that resulted for the accident during his experimentation to happen, causing for his body to be genetically altered, giving him various mutant powers and abilities.

Later, he then even shared his philosophy of Social Darwinism, which led to his obsession researching Charles Darwin's concept of evolution and natural selection, such as discovering the possibility of turning a human into a mutant or vice-versa by altering it's genetic composition. Becoming the immortal genius known as Mister Sinister, he became very successful in his researches and became perhaps the greatest geneticist in the world, since he is capable of cloning, creating, enhancing, and controlling mutant abilities for many centuries such as becoming a Nazi geneticist during World War II working alongside Adolf Hitler and Johann Schmidt, the Red Skull.

After World War II, he was forced into exile and after those following years, he restarted his new life in the United States under new several aliases and identities. He even founded his own clinic, Essex Clinic and though he had many aliases overtime, he never changes his beliefs in his life and still believes his own ideologies and personal knowledge that he gained throughout the centuries.

Eventually, his main goal as a corrupted and an immoral geneticist is to become the most superior being in the world, more superior than any species of any creature that's been living on the planet, including mutantkind and humankind.

During Apocalypse's return in the early 1980's, who was later defeated by the X-Men, Nathan became extremely curious about the Egyptian mutant's whereabouts since he was "killed" by the mutant team and thought of the possibility of him not being permanently dead, believing that he might return once again soon and will come back with a vengeance against humanity. His theory was later proven to be in fact true, after revealing that Apocalypse has explained to him later on, that he had indeed, survived the Phoenix's incineration by the second he was able to transfer his essence and consciousnesses into a random civilian's body, who unfortunately has already died during the partial destruction of Cairo, Egypt.

Obsession for Power

After discovering the rise of mutant population which had impressed and fascinated Essex, he decided to study it's cause and how it became possible. After becoming obsessive with collecting DNA samples from various mutants and other mutates he had discovered and researched, he tries to infiltrate the famous X-Mansion, the place where the Xavier's School for Gifted Youngsters is located, so that he could collect samples from as many mutants as he could before getting caught by Professor Charles Xavier, who detected his presence.

The X-Men who was alerted, immediately confronted and tries to apprehend him causing for Nathan to attack them. He manages to almost to defeat the X-Men until Xavier manages to paralyze him via telepathy and telekinesis. Though paralyzed, he couldn't stop taunting Xavier and the X-Men until was immediately punched by Wolverine, knocking him down to keep "his mouth shut."

He was held in custody in the laboratory until he suddenly woke up and stole some of the mutant samples before he successfully escaped the mansion and evaded Professor X's telepathic senses and even before he could use the Cerebro to track his current whereabouts.

Gaining Trust

Realizing that he had no chance against the X-Men alone, he eventually allied himself with Magneto and joined his Brotherhood, pretending and introducing himself as a believer in mutant supremacy as well as being an anti-human, believing that mutants should and will always be the top of the food chain, though in reality he joined so they could help him gain the upper hand in defeating the X-Men and as well as studying and manipulating their mutant (including the Brotherhood) powers and abilities and also getting each of their DNA so he can conduct an experiment by genetically alter himself once again, so he can be more powerful than he was before.

He was so manipulative overtime that he even manages to earn the trust of Magneto and the rest of the Brotherhood) except for Magneto's closest loyalists, who already had a secret suspicion against him), causing for him to become his right-hand man when they are in a war against fellow mutants, such as the X-Men or humans, such as the Avengers and the Fantastic Four.

As a high ranking-member of the Brotherhood, Mister Sinister surprisingly conducted a few terrorist attacks by taking down several organizations with the help of his hybrid enhanced sleeper agents that he created in his lab using the genetic samples of the mutants and mutates he once collected from. From time to time, Sinister had the desire of gaining power and control over all living organisms on the planet, since he desirably wanted to harness and manipulate the evolution of life in this planet.

The Movement

He began observing and studying every tragic and disastrous events in the world, and thus he realized that the state of modern civilization is worsening from time to time due to the existence of enhanced individuals such as the mutants and mutates, realizing that sooner or later, the community that relies on super-powered individuals would eventually collapse. Due to this, he plans on creating a massive revolutionary war that would be much worse than any other war in the history of the world, so much worse it could create a new movement throughout the civilization as we know it, where the world will be ruled by terrorists, following an established new world order.

One of his first main moves was offering an alliance with several terrorist organizations including the all-powerful and all-superior Hydra, A.I.M., the Ten Rings, the Liberators, Sinister Seven, Loki and his Asgardian and Frost Giant allies, and with the help of his alliance, they even manage to communicate with an extraterrestrial race known as the Skrulls, and manages to convince them to help Sinister unleashed chaos and destruction on Earth, during the upcoming war. Their goal is to gain the all-power, dominance, and control all over the world in order by creating a new world order. After their successful alliances, they conducted a series of massive terrorist attacks that destroys the several monuments and structures throughout many different countries the world such as the Brooklyn Bridge, Golden Gate Bridge, Eiffel Tower, Taj Mahal, and even the Great Wall of China, killing over 1,500 people on the first day.

Betraying Magneto

After revealing his true plans to Magneto and his intentions to the Brotherhood such as the threatening Magneto of eradicating mutantkind and allying himself with several organizations Magneto has despised of, including the Nazi-based Hydra which Magneto had been despising off since his childhood. As a result, Magneto demands Sinister to leave his team, though during his time as a member he manages to earn the trust of several mutants, gaining allies inside the Brotherhood and those members include three of Magneto's loyalists, Multiple Man, Mastermind, and Hard-Drive, while the rest of the traitors had been brainwashed by the villain, leaving only few members who still stood by Magneto's side, his loyalists. Due to Sinister's betrayal, the Brotherhood broke into factions, Magneto's and Sinister's side. Magneto and his faction later allied themselves with the Ultimates and the rest of the heroes to end Sinister's reign of chaos.

Due to Nathan's tactical brilliance, the tragic global event that he created was now known by the entire world as the Ultimate War (also known as the Global Superhuman War and The Movement or The Superhuman Movement) spreaded in not less than a month, causing millions of casualties all around the world caused by several terrorist attacks, extraterrestrial attacks caused by the Skrulls that resulted into many destruction and ruins throughout cities and many populated areas, affecting the lives of million people worldwide.

Though it became devastating for an amount of time until the war was beginning to slowly end, thanks with the help of the peaceful alliance of the Ultimates, S.H.I.E.L.D., and many other peace-keeping agency and/or organizations in order to end the war by being victorious waging war against the society of villains who supported and joined the new world order that Sinister and the rest of the superiors have established.

Defeat and Death

During the final battle, Sinister's faction and his separated Brotherhood were confronted by the X-Men and Magneto's Brotherhood in his own fortress in Sokovia, in order to finally end his reign of terror. The battle lasted for hours, with Sinister and his subordinates killing several heroes and anti-heroes who opposes him until he was the only one left standing after his allies were either killed, escaped the war-zone, or were saved from his coercion.

Somehow, Sinister still manages to escape Sokovia again until he was found by Archangel and a few mutants to stop him from escaping. Sinister outmatches his enemies after absorbing all of their powers and killing them, until Archangel battles him to save his son, Angel. He almost defeated Nathan, until they crashed into a thermal power station, critically injuring both of them. Warren (Archangel) was starting to recover to his regenerative healing factor, until a disfigured Sinister suddenly lunges at Warren and absorbs all of his powers, draining him including all of his healing factor, causing for Warren to slowly die from his injuries. Shortly after Warren's death, Sinister suddenly vanishes after leaving the scene.

In the end he was eventually founded by the mutant resistance once again in Genosha, after a dying Archangel threw a tracker on him without him noticing it, earlier during their battle. In the end, all of Sinister's clones were killed and he as well was finally defeated after he was defenseless after being surrounded by the X-Men and the Brotherhood who used all their strength and powers against him that disintegrated the villain in the process, killing Mister Sinister and ending his tyranny and the Ultimate War once and for all.


Weeks after the war has ended, a secret Hydra operative team led by Baron von Strucker and his men visited Nathan's now-abandoned fortress and "cleaned" the scene up where Sinister was recently defeated by the heroes. During their "clean-up," they found a tiny glowing scarlet mark diamond (Same as the one on Nathan's forehead), lying on the spot where he was disintegrated. Strucker picked it up and examined it, sensing that there is something very interesting inside the scarlet diamond.

In a secret Hydra facility and laboratory, they further examined the diamond and discovered that it is made up of advanced but ancient nanotechnology, after finding out that Nathan's consciousness is contained inside the diamond. Weeks later, they managed to created a replicate a new lifeless, duplicate, organic body of Nathan and somehow they manage to attach the diamond into the lifeless duplicate, causing for the consciousness to resurface and wake up into his new body. After waking up, Nathan got confused, unable to recall anything that has happened to him recently until Strucker gave him a few hints, before remembering that he died battling the X-Men and the Brotherood.

Hail Hydra!

Sinister 61615 3

Mister Sinister returns to the world as a high-ranking superior of Hydra

Strucker then offered help for Nathan in order to get all of his powers and abilities back, but with one condition. Nathan has to join Hydra so that, they can help him become a powerful enhanced individual once again and by also Nathan helping Hydra rise up again into society after it fell into the ground during the end of Hydra Uprising. Nathan accepts Strucker's offer and spoke the words, "Hail Hydra." before the two of them smirked. Eventually Nathan truly became Mister Sinister once again after slowly regaining his old powers and abilities back and as well as gaining new ones, thanks to to Hydra's help.

After a short while, Sinister eventually became a high-ranking Hydra superior after helping them somehow battle against S.H.I.E.L.D. and other superhero organizations all around the world such as his oldest enemies, the X-Men and the Avengers. Unlike his history with the Brotherhood, he decide not to betray Hydra, not just yet anyway, since he can use it as an advantage for his new, mysterious crusade.
