Ultron Sigma

We are born of two universes. Each of them imperfect, each of them afflicted with the cancer of organic life. From their ruins, a new universe shall be forged, in the fire of the stones of reality, and space. All life remade in our image, in steel, free from the sins of flesh. We are Ultron Sigma. We are your god.
Ultron Sigma

Ultron Sigma is the primary antagonist of first part of Marvel vs. Capcom: Infinite. He is the result of the fusion between Ultron and Sigma.

Profile[]

Abilities[]

Being the complete gestalt of Ultron and Sigma, Ultron Sigma possesses both individual machines powers combined, along with two of the Infinity Stones, the Reality Stone and the Space Stone. As such, he is one of the most powerful beings seen from the merged universes, with his power comparable to a god's. Their usage of the Reality and Space Stones was the cause of the Marvel and Capcom universes to merge, and they can use the stones in conjunction to tear open holes in reality and rain energy meteors down upon their foes in one of their Hyper Combos.

Ultron Sigma displays almost nigh-invulnerability, his chassis shrugging off blows from the likes of Thor's uru hammer Mjonlnir, Captain America's vibranium shield, and X's Nova Strike, as well as being immune to bullets entirely. Ultron Sigma's high durability more than likely a holdover from his previous form as Ultron, who preferred bodies made of various indestructible metals, adamantium and vibranium chiefly.

Ultron Sigma's strength level is high enough to allow him to effortlessly battle almost the entire joined heroes from the Marvel and Capcom universes alone, defeating the likes of Thor, Dante, and overpowering X, as well as throw the diminutive Arthur aside with no effort, and hoist two Asgardians up by their heads.

Along with his great speed, Ultron Sigma retains Ultron's flight capabilities and Sigma's teleportation ability, allowing him to fly long distances and remain aloft in the air, seemingly indefinitely, and the increased power drawn from the Infinity Stones allows him to teleport much greater distances compared to Sigma's short range warp.

While Ultron Sigma retains Ultron's death ray lasers, he makes more frequent usage of a purple beam saber comparable to Sigma's previous green one, using the saber as his main weapon in his battles against the united heroes of the Marvel and Capcom Universes.

Ultron Sigma's most dangerous power is their final holdover from their time as Sigma: The Sigma Virus, once known as the Maverick Virus. Enhanced by the Reality Stone, not only does it retain its ability to infect most machines and enslave them to Ultron Sigma's will, it now has the capabilities of infecting organic matter, transforming those infected into mechanoids, organic/machine hybrids controlled by Ultron Sigma.

While almost all-powerful, Ultron Sigma is not without weakness despite their godlike image. Because they are a machine at their core, their circuits are vulnerable to overloaded charges of electricity, which can leave them severally weakened and vulnerable to attack. Also, while their chassis is almost totally indestructible, the Infinity Stones they display on their head and chest can be damaged, which in turn harms them and can potentially undo their fusion. After Thanos damaged the Reality Stone on their forehead, Ultron Sigma's body briefly destabilized, with flickering images of their two progenitors briefly visible as they struggled to maintain their fusion while expressing outrage at being harmed.

Also, as they are machines, they do not possess a true soul, and as such, when they tried to use the Soul Stone, the stone rejected them, causing their body to overload and mutate into their Ultron Omega form, that while more powerful, was vulnerable to destruction.

Story[]

Marvel vs. Capcom: Infinite[]

When Mistress Death and Jedah Dohma used Thanos to begin acquiring the Infinity Stones as part of a plan to merge their separate universes and annihilate half of the combined population to achieve a twisted "equilibrium", Thanos first gained the Space Stone needed, but the Reality Stone had been lost in Jedah's reality and protected behind an impenetrable barrier around Abel City. Thanos struck an accord with the artificial intelligence Ultron, who would hack into the city's servers and disable to the barrier so the Reality Stone could be found and recovered. Ultron initially simply proposed killing Thanos and taking the Stones for himself, but Thanos convinced him to instead keep the advanced technology from Abel City instead, telling Ultron that he lacked a soul needed to control the Stones power.

Ultron agreed, and after Thanos used the Space Stone to take them to the city's edge, Ultron proceeded to hack into the shield to disable it, where inside the digital mainframe he encountered Sigma's digital avatar, who threatened to destroy Ultron for infringing upon his territory. Both Ultron and Sigma studied each other's internal coding, with Sigma impressed by Ultron's code while Ultron himself compared Sigma's viral code to a "hymn of order", before calling his physical form ugly, a mockery of human. Sigma explained his current body was simply one of many he had worn over the years and had no personal attachments to it. Ultron then proposed an alliance between the two of them due to their shared goal: the destruction of all biological life. Sigma agreed, and while Ultron initially wanted to use simple violence as the means to their end, it was Sigma who proposed a different method.

The next day, Ultron brought Thanos to Sigma's laboratory, and swiftly attacked and destroyed Sigma's physical body, taking the Reality Stone from his "corpse" and downloading Sigma's programming into his own body, infecting himself with Sigma's viral coding. This created the combined personality of the two that declared themselves Ultron Sigma, before battling and defeating Thanos to claim the Space Stone. With the powers of the Reality and Space Infinity Stones, Ultron Sigma fused both of their universes together and remade Ultron's body into a new form that combined elements of both of their physical bodies, turning Sigma's lab into a production factory of Ultron Drones before declaring that steel would replace sinew in their new reality.

With their combined power and the strength of two Infinity Stones at their disposal, Ultron Sigma declared themselves the god of the newly combined universe and over the course of three months, took over the throne of Xgard, the combined realm of Asgard and Abel City, while keeping Thanos imprisoned to pry the knowledge of the remaining Infinity Stones locations from the Titan. Using the power of the Reality Stone, Ultron Sigma enhanced Sigma's Maverick Virus, allowing it to infect organic life instead of only mechanical, all the while converting living victims into Mechanoids, slaves to Ultron Sigma's will. They also aligned with Grandmaster Meio, who controlled Knowmoon, the combined Knowhere and Third Moon, who began to prepare a special Gravitron filled with the Sigma Virus and powered by the Power Stone to infect to the Earth.

The heroes of both dimensions united to stop Ultron Sigma from achieving his goal of destroying all organic life, and stormed his citadel on Xgard. Bemused by their defiance, Ultron Sigma personally battled them near the end of their first invasion, infecting two Asgardians to mock the god of thunder, Thor, before defeating him and Spencer in combat, afterwards shrugging off multiple attacks from the heroes, all the while mocking them for their powerlessness. Ultron Sigma began infecting Thor with the Sigma Virus but Doctor Strange managed to teleport all the heroes out of Xgard, along with Thanos, whom they had come to rescue. Though his enemies had escaped, Ultron Sigma had succeeded in infecting Thor, and shortly after took control of the thunder god to attack the heroes at Avengers Tower.

The heroes managed to fend Thor off, and Ultron Sigma simply teleported him back to Xgard, all the while speaking to the heroes through their monitors to explain their dream of a new, perfect universe under their rule, free from the sins of flesh. Ultron Sigma warned them that they would all become infected eventually, and urged them to accept their "gift", before cutting the transmission.

When the heroes convinced Thanos to tell them where the remaining Infinity Stones were to use their power to combat Ultron Sigma, the mechanical monstrosity sent their drones to Valkanda and managed to infect the Elder Dragon Dah'ren Mohran and used it to attack the city, only for Ryu and the Hulk to stop and slay the beast, saving the city and convincing Black Panther to hand over the Time Stone to Captain America.

While the divided heroes searched for the remaining Infinity Stones, Ultron Sigma staged an attack on Avengers Tower to kill Thanos, declaring they had no more use for the Titan since the locations of the remaining Infinity Stones had been revealed to the heroes and Ultron Sigma by proxy. Breaching the tower, Ultron Sigma bid Thanos to bow to them as his new god, but Thanos mocked Ultron Sigma as a child playing with the power of the stones as toys. Enraged, Ultron Sigma attacked Thanos' cell, which left them vulnerable to a combined attack from Iron Man and Nathan Spencer's Unibeam and electricity charged Bionic Arm. Weakened, Ultron Sigma was attacked by the newly freed Thanos, who pummeled the machine into submission and cracked the Reality Stone embedded in their head, which almost undid their fusion.

Infuriated at being injured, Ultron Sigma declared that in time they would all come to them, before teleporting back to Xgard to repair themselves. While the heroes managed to acquire the Time, Power, and Mind Stones, and used them to destroy the Sigma Virus gravitron bomb and Giant Symbiote created by Jedah Dohma, they were unable to seize the Soul Stone from Jedah, and the destruction of the gravitron infected all of them with the Sigma Virus. With no other choice left but to destroy Ultron Sigma before they succumbed to the infection, the heroes stormed Xgard again, while Thanos, Iron Man, Gamora, Ryu and Frank West raided Sigma's abandoned laboratory to complete Iron Man's weapon to defeat Ultron Sigma once and for all.

Ultron Sigma welcomed the invaders to his throne, and sent their drones and the infected Thor to attack the heroes, all the while mocking their efforts as futile and that they would soon possess all of the Infinity Stones needed to finish remaking their merged universe into a new reality with them as god. Mocking the weakening heroes, Ultron Sigma questioned their motives, before revealing they were aware of Dante's efforts to retrieve the Soul Stone from Jedah Dohma in the Dark Kingdom and their hopes that he would save them all, before revealing Dante was already in Xgard and had turned over the Soul Stone to Ultron Sigma, seemingly betraying them all.

Ultron Sigma then attempted to use the Soul Stone to take all the heroes souls, only for their attempt to backfire as the Soul Stone rejected Ultron Sigma, whose body began to glow and writhe about in agony as they questioned what was happening to them. Dante revealed that only the noblest of souls could use the Soul Stone's power, and the simple fact that Ultron Sigma had no soul meant they could not channel or use its power. Screaming in pain, Ultron Sigma's body exploded in a burst of light, destroying their throne, but this was not the end of them.

Calling out from the smoke, a massive mechanical hands seized Dante, and Ultron Sigma were revealed to have survived, their body mutated into the mechanical abomination that declared themselves Ultron Omega. Spider-Man tried to snatch the Soul Stone back, only for it to fall into the infected Thor's hands. Ultron Omega ordered Thor to use the Stone to kill the heroes, but the Soul Stone cured Thor of his infection, allowing him to help the heroes save Dante. Soon after, Iron Man returned and revealed their ultimate weapon: the Infinity Buster, a weapon wielded by X and capable of channeling the remaining four Stones powers to destroy Ultron Omega once and for all.

Though Ultron Sigma was finally destroyed, the damage Thanos inflicted upon the Reality Stone meant the two worlds remained fused together, and all the lives ended by them in their mad ambition for godhood could not be restored.

Gameplay[]

In the first battle with Ultron Sigma in Story Mode, it is unbeatable, reading inputs, not being able to drop below 80% health, and the Hyper meter filling up like the Mind Stone's Infinity Storm.

In Arcade Mode, Ultron Sigma is the sub-boss, just before Ultron Omega. The Arcade version is much easier than the one in Story Mode. In Arcade Mode, Ultron Sigma is alone and doesn't have minions on its side.

Ultron Sigma has possession of both Reality and Space Stones in gameplay, allowing the use of both their Infinity Storms.

In regards to gameplay, Ultron Sigma retains most of Ultron's original move set, with Sigma's teleportation ability and swordsmanship in the mix. Its Hyper Combos are the exact same as Ultron's, with the addition of an extra Level 3 Hyper Combo that allows Ultron Sigma to summon a powerful meteor shower at will.

Trivia[]

Despite Ultron Sigma not having the capability to wield the Soul Stone, the fused robots, including their original halves can use the Soul Stone at ease outside of Story Mode.
As demonstrated by Ultron within Hank Pym's body in the prelude of Marvel Comics' 2018 comic book event Infinity Countdown, the only way for Ultron and Sigma to use the Soul Stone is that they need to possess organic hosts, such as humans, and trap their souls inside the said stone in order to use its full-power, without having side-effects. Not possessing the knowledge on possessing organic hosts first in order to be able to tap into the Soul Stone's power was a major mistake and the biggest weakness for Ultron Sigma, which turned them into Ultron Omega and cured the Sigma Virus.
