Prologue: Sinister Metal Fusion
An Unknown Earth.
BGM-Marvel Future Revolution OST-Xandearth (Instrumental)
The multiverse is in the middle of a quiet chaos. Shadows lurk behind the unchanging peacefulness of everyday life. Twisted beings writhe unseen in the darkness. Mysterious dimensional portals connect the real world to others more amazing. But with the passage of time, people eventually have come to understand and even accept these things as part of their daily lives. All without knowing of the existence of the people fighting for control over the fate of all worlds.
One Earth is about to meet its fate by the hand of true evil. The entire planet is cracking to its destruction, under siege by the most powerful alien fleet in the multiverse. The deserted Tokyo city known as Shibuya is on fire, caused by an epic showdown between this world's two greatest heroes and the Ultimate Evil. That Ultimate Evil being Thanos shrugging off the pathetic attacks of Reiji Arisu and his sage fox partner, Xiaomu. These two work for Shinra, an organization that battles against evil spirits, demons, monsters and all others threats from different worlds that seek to harm humanity. It is unfortunate that their best efforts are not saving this world from the Mad Titan.
"ENOUGH!" Thanos exclaimed upon sending Xiaomu flying with a brutal energy punch, swiftly before catching Reiji's sword and throwing him at his partner to defeat them both.
"Xiaomu, get up!" said Reiji, grabbing her arm as he desperately tries pulling her up.
"Five more minutes…" quipped Xiaomu, too groggy as both Shinra agents are spent.
"How unsatisfying." Thanos mocked, nowhere near worse for wear compared to his defeated opponents.
"We are not giving up, Titan! The fate of all worlds hang in the balance!" Reiji scowled.
"That is exactly why I am doing this. To bring order to this chaotic multiverse." Thanos claimed, vaguely hinting to them of his multiversal master plan.
"Keep telling yourself that. Sure you're not just trying to impress some chick?" Xiaomu snarked.
"Whatever your reason for destroying dimensions, I promise you WILL be stopped! One way or another!" Reiji declared.
In a horrific response, Thanos raises his left gauntlet that is embedded by a mysterious purple cosmic Stone that begins glowing while he says, "Not by your hand, certainly.", before punching the ground with it. The entire Earth is overloading with energy from the Stars, and before the Shinra agents knew it, the planet detonated with intense violent force.
This dimension is now nothing but space dust, just like every dimension the Mad Titan invaded before. To a victory tune composed of a million dying screams. Thanos sits on his Space Throne in space surrounded by corpses and rocks, ready to move on as he grabs a floating military helmet that gets him contemplating, "Another universe. Endless sacrifice. All for you. Are you satisfied now, my love?" Mistress Death made it known that he was heard by showing him a vision in the helmet. It was first her skeletal face, before transforming into eight cosmic Stones, as if to remind him of his mission. "Hmm. It seems not. Not until the Eight are found. Then perhaps I will win your favor…" He stated, using his throne to travel onto the next dimension primed for conquest.

Meanwhile…
"The Titan certainly has kept busy. He too is on the hunt for these Exo Stones?" asked by the Ultimate Killing Machine of the Prime Universe, Ultron.
Ultron stands alongside Doctor Doom in the latter's Latverian castle spying on Thanos behind an interdimensional window projected by his Convergence Device. Said device is designed to move freely between dimensions and space, and as the leader of the Multiversal Masters of Evil, Doom has been using it to help him conquer dimensions. That is until the Mad Titan decided to join this Multiversal War, prompting the mad doctor to modify his plans a bit. "Indeed. Multiversal variants of the Infinity Stones that he plans to acquire all eight just to appease Death. He is biding his time by destroying dimensions, waiting to invade this reality once we obtain the remaining Stones. Organic and synthetic alike face extinction." Doctor Doom explained to his latest ally.
"No wonder you sought me out. Killing him won't be a problem, just as claiming the power of these Stones will." Ultron expressed emotionlessly.
"You have no soul, machine. The true power of the Stones will remain forever beyond your reach." Doom lectured stoically, which sounded insulting to the power-hungry robot. Doom ignores his threatening gaze as his own eyes are focused in changing projections, switching from that destroyed dimension to a world set in the far-flung future, "But this city and its wonders can be yours while I claim the Exo Stone hidden in this dimension."
"A power to rival that of the Exo Stones…" Ultron remarked, convinced by the idea of acquiring that dimension's advanced technology.
BGM-Marvel Future Revolution OST-A.I.M. for the Future
"The Convergence Device will take us to the city's edge." Doom presses a button on his device, which seamlessly transports them both to this future dimension. "But the barrier…?" He then stares at the shield below his feet, too powerful for even an Exo Stone to breach.
"To breach the city's shield, I need simply will it so." Ultron claimed, readying himself to hack into the shield to disable it.
With eyes glowing a sinister red, Ultron jacks his mind into this dimension's cyberspace. He was successful in this attempt. Perhaps a little reckless, because immediately his stoic face is threatened by a green saber belonging to a kindred robotic spirit, "I could destroy you now, insurgent, purge you from these systems. Rewrite you from the inside out."
"And I you…Sigma." Ultron points at his dimensional counterpart: Sigma, the Evil Reploid seeking the ultimate evolution.
"Both of us would perish. A pity. Your code is…impressive." Sigma studied.
"Yours…is almost poetry. A hymn to order, and reason." Ultron admitted, feeling as just impressed by his counterpart's internal coding. "Yet your form is ugly, a grotesque parody of flesh." He then mocked.
"It is one of many I have inhabited. Merely a tool, I feel no…affection for it." Sigma explained.
"Then let us form an alliance. Let me set you free." Ultron proposed behind Doom's back.
"To what end?" Sigma questioned.
"All biological life must be exterminated. The soul's fire extinguished." Ultron elaborated.
"Agreed. But how?" Sigma wondered.
"With violence." Ultron expressed by clenching his robotic fist.
"There is another way. Allow me to show you." Sigma proposed.
BGM End
Sigma's Lab, Abel City. Earth-30847.
Shortly after their meeting in cyberspace, Ultron brought Doom to Sigma's laboratory. Where unions and betrayals happen. "You are here at last." Sigma smiled, turning around to face his interdimensional guests.
"The technology here is most definitely impressive…" Doom complimented Abel City technology, having half a mind to steal it for his own nefarious purposes.
That'll have to wait as it's time for Ultron to enact his own nefarious plot, starting by destroying Sigma with a swift attack. The Evil Robot takes a pink Exo Stone from his corpse and downloads Sigma's programming into his own body, infecting himself with Sigma's viral coding. "AAAAAARRRRRRRRGH!" Ultron growled, as the red highlights around his body are turning into a more sinister purple.
"Ultron…" Doom calls him out with slight concern and curiosity.
"Our name is Ultron Sigma!" They corrected their now-former ally. "We have become as one…and the terms of our deal have changed." Ultron Sigma declared, looking imposing with the mysterious Exo Stone in their grasp.
Doom just crosses his arms stating, "Disappointing.", to express just how much unsurprised he is by their secret alliance. And how ready he is to crush it.
BGM-Marvel vs. Capcom: Infinite OST-Battle Against Ultron Sigma
"You have made a grave mistake, Ultron." Doctor Doom threatened, still in his cross-armed fighting stance against the Ultimate Merged Machine.
"No…all is as we planned it." Ultron Sigma claimed, striking their sinister fighting stance against the Latverian Monarch.
Their dimensional battle starts off swift and powerful, with Doom's Plasma Beam being countered by Ultron Sigma's Death Ray. Both collide with intensity that lasts a few seconds until Doom overpowers his merged foe, slightly pushing them back. Ultron Sigma retaliates by harnessing their Exo Stone, granting them a cosmic pink aura that evolves their power to the utmost limit, allowing them to pummel the doctor with fatal dashing claw swipes that ends with them uppercutting him into the air. It took a moment for Doom to recover using his jet boots and rain Hidden Missiles that forces the robot to counter with more energy blasts, all that were barely dodged by the monarch before he delivers a Foot Dive that missed.
"SPHERE FLAME!" shouted Doom, firing a large energy sphere straight at his opponent.
"DESTRUCTION WAVE!" exclaimed Ultron Sigma, unleashing two large and powerful energy beams at their rival.
Their Hyper Combos collide with greater force than all of their attacks up to now. But, there can be only one winner. And that win belongs to Ultron Sigma, tapping into more of the Exo Stone's power to overcome the doctor with raw devastating power.

BGM-Mega Man Maverick Hunter X OST-Sigma Transforms
Doctor Doom lies on the ground knocked out, with wires and other strange circuitry poking out of his decimated body. "A Doombot." Ultron Sigma realized that the doctor they fought was a fake this whole time, which doesn't surprise them in the slightest. "It doesn't matter. He has already shown us the tools of his own extinction! The living of two universes shall be laid to rest in a single grave!" By clenching onto the full power of his Exo Stone, the merged machine transforms. Evolving into a black-and-gold Ultron with Sigma's façade spread across their torso, with the pink Stone embedded on the former's forehead while the latter just gets a shiny blue gem. Upon flaunting their new red cape, Ultron Sigma declares, "Where there is sinew let there be steel!", as they begin their own plans to conquer all of reality.

In an Unknown Laboratory…
BGM-Transformers: Devastation OST- Operation Obliteration
"They thought they could trick Doom? Their fusion with the Evolution Stone will only make them more foolish." scoffed by the real Doctor Doom, having been using his Doombot to spy on the traitorous robots from another location as he anticipated their betrayal.
"Then you thought it smart to come to me for help. Seems you found an alternate power source to get through the front door without much trouble this time." said by a mysterious scientist that loves wearing a black long trenchcoat in the shadows. "I must ask: What makes you certain I won't betray you as well? Our previous alliance didn't end on the best terms." He asked, revealing some past connection with the Latverian.
"Betrayal means the death of your precious projects if either Thanos or Ultron Sigma gets their way. They challenge your path to godhood over this world while I merely seek conquest of my own Earth. Assist me in their destruction and you will gain power beyond imagination. Far greater than the World Devourer that heightened tensions between us. Do we have a deal, Mister Wesker?" Doom proposed smoothly to his dimensional counterpart walking out of the shadows.
That counterpart being Albert Wesker, a superhuman mad scientist formerly of the Umbrella Corporation. "Fine. I don't have time for interferences, so let's make this quick." Wesker agreed to this new alliance, joining the Masters of Evil in their own bid to conquer the multiverse.

BGM-Marvel vs. Capcom 3: Fate of Two Worlds OST-Gallery
KFX Here: Ultron Sigma is the main villain of this story, with the Masters of Evil being secondary baddies. Thanos won't be a problem again until Exo War RX, so I hope you enjoyed his little cameo here.
Nathan Ramos: No plans to adapt RWBY Volume 9 right now.
superjoeyf721: My version of the Capcom World is inspired by the World of Project X Zone. Basically an amalgamation of different Capcom franchises, with different timelines playing a crucial role. Whatever plot element that was relevant, like say multiple virus outbreaks in the Resident Evil World, might not matter here. This way I'm given more freedom in how I write these characters without being bogged down by pre-existing canon. I'll explain more as this story goes on.
Braewriter of Rewriting: I'm not doing any more remakes past Exo War. Or at the very most Contest of Smashers.
silverfox26: Haven't played it yet. Maybe one day.
