Extended Summary
The very fabric of the world will find itself torn asunder as entities merge to form a new threat – Ultron-Sigma, an anomaly formed from two machines out to destroy humanity, is set to make its mark once its competition in the world domination market is thrown aside, and it starts by converging the Earth that hosts heroes and villains of Marvel alike, with the Capcom multiverse. Chaos will ensue, and the heroes must face not only the threat that brought them together, but themselves.
Basically, this is a retelling of the story mode that was created for Marvel vs. Capcom Infinite – at least, my retelling, and it's sort of a nice little hello to the fanbase that wanted something more out of the story mode than what was received.
The structure of the story will be somewhat the same, but it won't be just the roster that Marvel and Capcom arranged to begin with – a whole lot more characters will be involved, including some you might not expect when you first think of characters that should've been involved in the first place.
With that being said, let's head on with the show...!
Seoul – the capital city and heart of South Korea. It became a battlefield before long.
Shreds of metal and bolts littered the landscape, the destroyed remains of drones battling out against humanity to failed efforts. The streets were devoid of civilians who either moved aside out of their own will, or at the enforcement of others, whether from good or from evil.
A battle had been going on for some hours now, and was slowly crawling to an end as one force looks to fully triumph over the fading opposition.
A super-soldier encased in the colors of the American flag, appropriately known as Captain America, picked up his near-indestructable shield from the muddled remains of a drone split in half at the waist, barely succumbing to fatigue despite fighting for a good few hours.
Near him, a warrior with a medieval-esque look to his battle armor hovered back down to ground level, a hammer buzzing with lightning held in hand. The king of Asgard, Thor, felt nothing but wind ahead, and heard very little. "Do you feel it, Captain?" he asked, "...The tides of war may be finally calming..."
"'May be' could be right," The super-soldier in red, white and blue responded, "but it's hard to say; it's all dependent now, on whether he still roams."
Some sounds of objects being crushed caught Cap's attention.
Nearby, a green-tinted monster of a man stomped over some of the other drones' metallic corpses, slowly noticing the quiet – his temper slightly fades as he recognizes the end-game of this war between man and machine. He was quickly joined by another of the heroes, a woman in red and blue who descended back to the ground from what could be presumed as some skyward battles alongside the skyscrapers.
"You okay, Bruce?" Captain Marvel, one of two 'Captains' on this current team, calmly asked the green behemoth to her side.
The green monster, 'Bruce', spoke in his somewhat mutated and broken English, sounding a slight bit awkward against the calm air. "Too quiet. Hulk doesn't like quiet..."
"You aren't completely wrong there..." Marvel then looked around, briefly taking notice of Cap and Thor just a few feet to her right, a "Where the hell's Tony?"
"Right ahead of you, Carol..."
Hovering down in front of the four heroes, Tony Stark returned to Earth in the full-body armor that fittingly coined him the moniker of 'Iron Man'. "Sorry for the hold-up – the good doctor and I needed to carry some luggage back down to Earth with us."
He dropped to the ground the ringleader of the metallic rebellion that went on: Ultron... or at least the upper-half of him, after one hell of a brawl across the skies.
The 'good doctor', one Dr. Stephen Strange, joined the rest of the team before long, as his cloak brought him down gently to the ground alongside Stark. "The outcry of Ultron's swarm has been silenced – it's safe to say, the rebellion is finally over... but what did it cost in the end?"
Iron Man surveyed the torn Korean city that he and his fellow heroes stood in. "A safe bet: a whole lot of property damage – nothing I can't afford, at least. As for our rusty tin can right here," he darted down at the halved body of Ultron. "Well, after what you've done, you're pretty much a waste of good resources."
The robot menace stirred back into consciousness, barely managing to weakly reach out. "Y-yoooouuu... you humans... are so pathetic. You may have stopped me now... but know that this... is only the beginning..."
"Yeah, yeah, whatever," Iron Man casually waved off the threat. "Send him away, Doc."
Dr. Strange nodded and promptly put his magic to good use, twisting together a set of arm / hand signs to enact a spell; as Ultron let out one more defeated groan, he was flashed out of this dimension under a small, bright portal.
Dismembered and exiled, Ultron and his rebellion had been vanquished, and the band of Avengers that battled against him were triumphant.
Ultron must've felt himself descend through all colors of the rainbow, in what felt like an endless abyss for the brief time he fell. When he finally did, he found himself planted into the dirt of a completely different world.
Recovering as well as he could, in his state of being literally just a torso, the defeated robot brought himself up as he looked at the landscape before him. Nothing but deep blue and black tones of color above a gray sky – a very bleak tone of colors that surprisingly fit his situation, after what he had just gone through to such a failed effort.
He was struggling to get by, as he crawled across, with his claws clamping into the gross, inky dirt. He didn't care what sort of devilish underworld he had been exiled to, he was going to find his way and get revenge on the Avengers that brought an end of his plans.
His visual perception systems were significantly distorted due to his battle damage, and he couldn't see quite clearly what was further down the land. He was certain that he saw something slowly begin to approach him, and he wanted to get closer to getting aid, and perhaps a chance to finally get vengeance. However, just a few feet away from meeting whoever was on the other side, ultimately gave in to the fading energy, stopping and laying down against the grime.
The footsteps that approached him grew louder, as it got closer to where Ultron laid...
He groaned out one more time, "Help... me..."
He was lifted up by the back of his torso in one strong hand...
"Come," said Thanos. "We have much to plan ahead for."
