Game in Marvel

"Yeah, I think they got the message." Tony smirked. Soon a portal tore open in front of them and these people were forced to go through the portal. The scientists were reluctant, but hearing the snarl of Fenrir, they didn't protest. Natasha took a step forward, addressing the Widows.

"This is your chance. You walk through that portal, you're free. You try anything stupid, and I promise, you won't like how it ends."

There was hesitation, but one by one, they stepped through, disappearing into the dark glow. 

"Well," Barton said, lowering his bow, "that's one hell of a relocation program."

After they had left, it was their time to leave too. Antonia was taken in by Natasha as she felt responsible for the child. Of course she would be medically fit first and also find out what after effects her father had left on her. She didn't even cry when Dreykov screamed. She seemed to be under huge trauma and was unresponsive. 

But all in all, with the mission wrapped up and the Widows safely transported, there was nothing left but to head home. Barton stretched his arms with a tired sigh, while Rogers adjusted his shield, while Fenrir opened a new portal for them.

But then, Liam stopped. 

He stood motionless for a moment before turning to see embers of the fortress as they dimmed against the snow. His expression darkened, enough to make everyone else pause.

"Liam?" Rogers frowned. 

"What is it?" Natasha asked. 

Liam didn't answer immediately. He wasn't able to see things clearly yet as his eyes shone in more brilliance then ever. But his questions were answered soon. At first, it seemed like shadows twisting through the wreckage, flickering in and out of sight. Then, something crawled out of the fire-charred remains. 

Its body was long and sinewy, covered in an eerie mix of bone-like plating and shifting tendrils of flesh. It looked like some kind of four limbed monster. Pale blue and green markings pulsed along its grotesque form, glowing faintly in the cold air.

Then another one emerged. And another.

More of them slithered and climbed out of the smoldering wreckage—beasts of unnatural design. Their eyes, hollow and soulless, scanned their surroundings, their hunger palpable in the freezing air.

"What the hell…" Barton muttered. 

"Does anyone know what those are?" Rogers asked. 

"Not ringing any bells," Tony said. "I can tell you one thing—those are not from around here."

Thus at the end they turned to Liam. Since they were monsters, and he was from the magical side, he might know them. 

"Liam?" Natasha asked. "You recognize them?"

Liam didn't answer right away. He just stared at the monsters with an unreadable expression. What he saw only confirmed his suspicions. These weren't just creatures. They were something else entirely. Something ancient. Something that shouldn't exist here.

He didn't expect to see them here. Though he knew that they existed, he had hoped to see them in the future and face them. 

"They are not from Earth, I can at least tell you that." Liam spoke for the first time since these monsters had emerged.

"It doesn't need a genius to understand that. What are these?" 

"Abhorrent experiments of some beings. Take them down and kill them. Don't let their tendrils touch your or stab you, or else they will copy your DNA and gain all your abilities. Yes, Tony including your intellect. These creatures are meant to evolve. They are meant to destroy everything on their path so don't bother with mercy. Fenrir, don't engage." 

Fenrir barked in disproval. 

"No. You are too big and if they copy you, they will be able to escape." Liam warned. He was serious. He didn't want these abhorrent creatures to touch them at all. Since Liam spoke of such warning everyone of them took the matters now seriously. Barton didn't even bother to get approval. 

It already shot an arrow at one of these monsters. It struck at one of the limbs, blowing it away, but tendrils and bones started to grow albeit very slowly, but it was still there. 

"They regenerate?" Barton was surprised. "Who created them?" 

Liam didn't respond and had already made a run towards these monsters. They were 6 in total from what he could see. 

"Captain.." Natasha looked at Rogers for their next move. 

"Barton you stay here and cover us. Tony take to the skies and bring down hell. Me and you will keep them away from sneaking on Liam as he will be the vanguard here. Now give them hell." 

Liam surged forward like a shadow, which had been given a form. He stopped upon the nearest monster and it also seemed to have smelled Liam. It lunged at Liam but thanks to foresight, it's attack carved through empty space, and before it could recover, Liam struck.

His form blurred as he spectral dashed behind the Deviant, his blade—Vigilance—slicing through its tendrils in a flash of silver. The creature screeched, ichor spraying from its wounds, but it was already regenerating.

But Liam didn't give it a chance. He used his bare hands alone to punch at the monster flying backward, its chest caving in from the force of the impact. And after the monster was punched, a huge ball of fire struck at the monster making it scream loud and within seconds it got burnt to a crisp in this chilly weather, showing how powerful the attack of Tony was. 

Yes, the others had now joined his fray. And so did the other monsters. 

The other five moved in immediately, their bodies twisting and contorting unnaturally as they swarmed Liam and Tony. Liam used his Shimmy and spectral dash together to dart through the air with impossible agility, his body propelled by magical bursts as he leapt from the wreckage, flipping over one monster while sending three consecutive Draupnir spear at one of the monsters, and simultaneously exploding them. 

Above, Tony soared through the air, unleashing repulsor blast at the one Liam just exploded. The blast went straight through the head of the monster. He took Liam's warning seriously—no mercy.
