If you see any Marvel stuff I'll just say its not based on any of the movies and instead on the Avengers: Earth's Mightiest Heroes universe, enjoy reading!

New York, the bristling city lights lit the night sky with its streets filled by people walking back home or having a fun time after a long day of work.

At least that's what it was till the creatures came in, now its a complete war-zone.

They skittered on 4 legs, their pincer-like mandibles killing anyone that got in the way.

SHIELD units had arrived shortly after the incident, their large helicarrier flying at high altitude.

"Where in the world are those four!? I wanna know what kind of crazy dimension they managed to open this time." Nick Fury, a major leader of the organization, asks.

"I've already contacted the Fantastic Four and they claimed that this is no work of their experiments, as for the complete closing of the portal they deem it is impossible to do so." the officer responds.

"Your telling me I have to quarantine this whole city!?" Nick adds.

"Unfortunately its the only viable way sir, unless we manage to completely secure the portal underground with automated defenses there's nothing we can do."

"Then tell our guys at the ground to go on the offensive! Get those quinjets in the air!" Nick shouts.

In the ground superheroes and SHIELD officials stand shoulder to shoulder in frantic defense.

The Avengers lead the unit, their battlefield presence was a sight to behold.

Iron Man leads the team, after tiring hours of holding against the monsters he receives a new order.

"This is General Fury of SHIELD, the Fantastic Four cannot close the portal, we need to steamroll our way through and secure it to cancel the constant flow of reinforcements."

That's definitely not the good plan I hoped for, but if its the only way to end this damn onslaught I'll just have to do it! , Iron Man thought.

He relays the order to his fellow Avengers and along with some agents behind them they commence their offensive.

The hide of these creatures were tough, requiring a ton of shots from the standard combat rifle, but that meant nothing to Thor's hammer nor the Hulk's all-powerful strength which he used to split them in half like a toothpick.

Iron Man's repulsor beams obliterated entire lines of bugs, only for those to be quickly filled with more.

"We need to keep on moving or they'll encircle us!" Captain America yells.

"That was totally not obvious from the fact that their endless!" Wasp adds.

"Endless!? The only thing "endless" here is my kill count!" Hawkeye gloats.

He sees a large clump of them, perfect for an explosive arrow.

But as he reached his quiver there was nothing left.

"So much for infinite arrows." he says, resorting merely to follow the group.

Out of nowhere a giant cockroach-like creature emerges from the ground and lets out a burst of scorching flame, the poor SHIELD agents are incinerated in both skin and bone.

Iron Man is quick to react, firing his miniature rocket directly into its head, the source of the fire.

Luckily for everyone this cockroach couldn't live without it.

But the death of this insect meant nothing to the enemies' growing numbers, which remained strong despite constant quinjet bombardment.

Soon Earth's Mightiest heroes found themselves surrounded,their allies' defenses slowly cracking under the constant attacks.

Just as all hope was growing bleaker by the second, another portal opens nearby.

Coming out of it were heroes from another world, their intention was supremely clear.

Among them was a tall muscular man wearing a red cape, he was first to break their group's silence with a loud yell.

"I guess you all know were not here to cause trouble, if you need more firepower we'll be ready to assist!"

For the Avengers and SHIELD it was music to their ears.

As the tables turned on their battle, the Imperial remnants on Middle-Earth continue evading the wrath of the New Republic forces.

The Imperial forces' first night on the new world wasn't what they anticipated, instead of peaceful star-filled nights they were greeted by attacks of the local fauna.

An Imperial officer and his stormtroopers check the casualties and supplies, as time grew their worries growing ever larger.

"If these issues keep up our supplies will be drained long before we go up those mountains, we need a better way around.", the officer warns.

"That will be hard sir, especially since we blasted those two strangers earlier, for now it seems we've made a mis-"

The stormtrooper is silenced in the form of a blaster pistol, he lies dead on the ground.

The officer brings out his communicator.

"Lets make this clear, only those who serve us willingly and unconditionally are accepted as allies, otherwise they are nothing but small ants waiting to be crushed under our still glorious power."

Every stormtrooper nods their head in forced agreement, soon they resume walking.

After a short while they sight multiple lights on the horizon, the officer inside his Spider-Walker takes out his binoculars and identifies a burning village.

Barbarians no doubt, such a primitive world without them is impossible, might as well get what's left., he thought.

The raiders wore leather padded armor with only a few wearing steel plating, their weapons mostly consisting of falchions, bows and war axes.

Preparing to engage, he prepares to line up his walker's laser cannons.

Before he could pull the trigger, a man covered in thick armor stopped in front of them, his arms raised in celebration.

The accent was the only thing different to the English the Imperials spoke.

"BROTHERS! Our courage ha'th been answered by Krie-Valka, the god of our cause! He has given to all who stood by his sword angels of hardened steel equipped with crossbows of light! The Ande-Ka has come'th for us!"

Each of the raiders were fixated on the Spider-Walker, the Imperial officer's mind raced with interest, a plan raced in his mind.

A few raids in villages here and there would make a nice distraction, enough for us to get away with a guide no less!, he thought.

Stepping out of the walker, he begins to gather needed information.

"Tell me the name of your cause so that the all mighty one can inspect thy spirit of your men's devotion, Lord "Krie-Valka" also demands that he'th test your faith in him by describing his holy image and giving his servants but a humble gift."

The heavily armored man spoke in his deep voice.

"We are the Zealots of Krie-Valka, the mighty one ha'th always been insulted with heretics who call themselves righteous, he is now but a force who is said to never impact us again...THE SACRILEGE NEVER FORGOT!"

The raiders wept true tears of sadness, the Imperials deep inside snickering of their complete madness.

"Krie-Valka has taken'th many a form from mage to royalty, but time and time again his cause remained the same...TO UNIFY MIDDLE EARTH! BUT DUE TO THESE UNDENIABLE HERETICS THEY DESTROYED THAT HOPE!"

Cries of rage erupted from them, shouting curses and stabbing the lifeless ground venting their hate.

"I am Eihen Thyronis, champion of this proud order, together with the leadership of our rightful queen Morena Ven Dymusian we gladly gift you these captured men and women for your own personal use, please do with them as you seek fit."

With a concluding bow, Eihen introduces a stunning young woman which was presumably their "queen", she also bows but remains silent.

The Imperials beheld the gifts given, men and women who for the sake of their lives willingly surrendered to be slaves, their future would only be grim.

"Now, introductions aside we ask you one more thing...are you willing to do everything for our cause?", asked the officer.

Eihen kneels and responds.

"Yes blesse'th won, we will give our entire lives in doing so."

The officer smiles, and walks toward Eihen, he whispers in the warrior's ear.

"Then we shall give you your prize."
