As Tony's faceplate hissed open, revealing the grim expression beneath, the team stood together at the fractured crossroads of 45th and Lexington. Above them, the rift widened, its edges pulsing with unstable light. And around them, the roars of an approaching horde echoed louder with every second.

Steve looked around at the assembled group. His eyes passed over mages and mutants, witches and warriors, gods and soldiers. Some were breathing hard. Some bore fresh wounds. Some had blood on their hands — not theirs, but that of friends, of strangers, of the innocent. 

He stepped forward.

"Listen up."

"I know what you're all thinking," Steve began. "This is bigger than anything we've ever seen. It's not just aliens this time. Not just one world in danger. It's every world. But here's the thing — we've been in the impossible before. We've faced those cold blooded bastards and evil men — and we're still here. You're not here because someone ordered you. You're here because you chose to be. And that choice means more now than ever."

He looked up at the sky, at the twisted, roiling colors beyond the rift. Then back down.

"They're not going to stop. They're not going to show mercy. But we are the line. The last, best line of defense this world — every world — has. And I'm not giving an inch. Not today. Not ever."

"I know you're tired. I know you're hurting. But you don't have to carry this alone. Look around you. You've got great friends among you. Whatever comes through that sky — we send it back or we burn it down.

Together...."

And before Steve and Liam could answer, they looked on the side and saw something that made Liam's eyes wide. They witnessed many web slingers, slinging around and finally landed in front of them. 

The first to land was a lean teenager in a black-and-red suit — unmistakably Miles Morales, his hood half-up as he struck a crouch. Next came Gwen Stacy, flipping in midair before sticking her landing gracefully beside him, her white hood casting a sleek silhouette against the burning sky. A robotic clank followed as Peni Parker, riding her SP//dr mech, dropped down with a metallic crash, scanning the area with glowing optics. Then came Spider-Man Noir, trench coat fluttering, the wind somehow always dramatic around him as he lit a match despite the chaos. Last, tumbling in like a man late for his third cup of coffee, was Peter B. Parker. 

Everyone froze.

Weapons were drawn. Magic shimmered at fingertips. Even Geralt's hand went to his silver sword. All were ready to engage. Except for Liam and Tony. Liam knew who they were and Tony, well, he had seen the video. 

"No way…" Tony muttered. 

"You know them?" Steve asked. 

"Kind of. I saw a video. They were the ones who took down the scientists and also the reason why the Tesseract blew up and have multiple holes around now." Tony replied. 

"Yes, sorry, you might believe us but we are ..." Peter Parker, being the oldest among them, came forward and spoke but before he could finish, Liam and Tony replied, together. 

"From the multiverse." 

Now it was the time for these Spiderlings to be surprised. They had arrived here 6 months ago. During the time when Ciri went haywire and then Miles, who was supposed to send them to their home (Spider man : Into the spiderverse) was sucked into a storm and all of them, including the Spiderham, landed in this universe. 

They were surprised to see that there were no Spiderman here but Peni and Peter mentioned that some stories of this world matched with their world which meant that they were still in the multiverse. They started searching and were able to find out Peter Parker and even the uncle of Miles Morales. 

This cemented that this world was just one of the versions but now they didn't know how they would get back to their world. Thankfully unlike their other multiversal travel they didn't face any rejections or else they would have long died. 

And this time they finally saw some hints of getting back to their world. Once the portal opened, everyone ran to the place and thus after some investigation were able to find out what was going on. 

Now that the portals had opened, they felt guilty as they didn't know that their small action had caused such a huge problem. 

"How did you.." Gwen was the one to reply. 

"We can have this conversation later. The main question is are you here to help or stop us from going forward?" Vesemir asked, being the level headed guy that he was, he didn't need to know where did these folks come from. 

The witchers owed the Avengers a lot and since this was their world and had been living comfortably, they didn't want anything to disrupt their tranquility. Now that these aliens had broken through, they just saw them as weak monsters. 

Okay maybe the Leviathan was the biggest monster. But at the end of the day, they were just monsters for the witchers and they were even getting paid for this. Vesemir had lesser time for bullshit now as people were dying around and they needed to stop it. 

"We are here to help in any way we can." Miles assured. And as he said that the Hulk landed right beside him. And surprisingly none of the the spiderman's moved as they all had their spider senses on and knew Hulk wasn't going to hurt them in anyways. 

This put a smile in everyone's face. 

"Alright," Steve said, raising his shield. "Let's end this. Avengers.. and allies.. Give them hell." 

With a synchronized cry, the army of defenders surged forward. Thor hurled Mjolnir skyward and summoned a pillar of lightning that cleaved through a descending Leviathan, sending its metal-plated corpse crashing into a parking garage.

Ciri blinked into existence midair and landed atop another alien beast. Her sword glowed white as she slashed through its organic armor, warping away just before the creature exploded.
