So Doc manager messed up and forgot to save some last minute edits. I had a whole Author's note and everything, damn.

Anyway, first off thank you for taking the time to read my fanfic. If you would be obliged and review or contact me and gave me feedback, then I would genuinely appreciate it. Secondly, I am going to rewrite the first two, maybe three chapters of the story. The grammar and spelling errors make me cringe as a reader, and want to face palm as the author that let such errors slip past his eye. Thirdly, I am going to try and bring the surviving Spartans from the novel Halo: The Ghosts of Onyx in. Why? Because it hasn't been done before, at least in a Marvel crossover and it would whoop ass that's why. Fourthly, Aunt May works as a nurse, guess what happened when the Chitauri were virtually unopposed? Aunt May is dead in this because I want to put a spin on Peter that wasn't seen until Back in Black. If you think the Punisher's a badass, Spider-Man out does him and it's amazing. Other characters will be added in, I know for sure Dare Devil is going to come in or rather bumped into. He and the other street-level vigilantes never left Manhattan. Essentially I'm going to try and find new ways to explore canon aspects of the Marvel cast and bring out the best or worst in them as my muse sees fit.

I don't own anything, except the Chimera that's mine! If I did own the franchises Halo 5 would have been a lot better.

In the Helicarrier Medical Wing...

After the Spartan had lost consciousness he was brought to the infirmary where the Avengers, X-men and newly arrived Fantastic Four could observe him. His brain waves were heightened and his brain was flooded with endorphins and serotonin. The massive super soldier, according to Professor Xavier, was processing his emotions with such intensity that he was forced unconscious to accommodate the surge of emotions. When Cortana had been in his head, sharing his gray matter, the telepathy used to treat her had a residual effect on the Spartan. A lifetime of suppressed emotions was unbottled and there was little else to do besides wait.

When the Spartan woke up seven hours later he was composed, and his stoic professionalism was back. Cortana had to share with what happened after Charles had treated her rampant emotional processes, and he just acknowledged that he went through a decompression of a lifetime of warfare and loss, then promptly asked what had been done while he had been out of commission.

Cortana chuckled in relief. At least, John hadn't been emotionally destabilized like the others had theorized might have happened. He donned his armor, introduced himself to the strange and unusual Fantastic Four team that blurred the lines between team and family even further than the Spartans themselves. John immediately liked the scientific professional demeanor of Doctor Reed, which was similar to Doctor Halsey's. With the new assets organized and the teams organized and the plan settled, the counter attack began.

On the Deck of the Helicarrier…

Chief was triple checking his customized Carbine, a creation of Cortana with the aid of Tony. Utilizing the latest Stark/UNSC weapons technology the Chimera was a heavy carbine that combined the best UNSC and Stark technology. The base weapon was designed to engage in medium range combat, but the larger caliber of rounds in the Spartan's Chimera extended that range to long range, with an adequate scope it could function as a Marksman rifle in a pinch. The bullpup carbine was barely 30 inches yet weighed twenty pounds when fully loaded. Tony had barely been able to shoulder the rifle correctly it was so heavy; John had little trouble handling the hefty rifle, though. To maximize the combat capabilities of the carbine, it was chambered for .70 caliber so it could fire identically sized 12 gauge shells in close quarters combat. The SOPMOD II package of the M4A1 had been blended with the BR's body, the mounting rails on either side of the barrel had an angled foregrip mounted on it with a grip on the bottom, virtually negating recoil. In Chief's hands, the rifle never missed, ever. In the thousand rounds that he had fired at full automatic, there were only two holes. One where the first bullet went and then the next where all the other bullets went, even after changing magazines and targets the same trend reoccurred. The sight on the top of the rifle had been created by Cortana probably had something to do with that feat as well. The scope utilized real-time sensor readings to project an augmented reality scope that showed bullet trajectory and hostiles directly to the HUD system of the MJOLNIR. John was tempted to fire it from the hip, but the recoil would wrench the rifle from his grip if he relaxed while firing it even a minute amount.

The Spartan's sidearm was a 3D fabricated M6, chambered to fire .70 caliber rounds as well so Chief wouldn't have to maintain two separate ammo caches. His pistol was magnetized to his right hip adjacent to a magazine of magazines, all the Spartan had to do to reload was eject the clip and slide the magnum through the mechanism, then he was ready to fire again. If for some reason his beast of a carbine and pistol weren't enough the Spartan also had an assortment of blades magnetized to his armor pauldrons, a clip of throwing knives magnetized just below his collar, a pair of monomolecular diamond edged Karambits were mounted on his chest. The Spartan was clad with a belt of clips over his abdominal armor. Decked out with a line of grenades in a metal grenade holster mounted on the small of his back and enough charges to level a building in a case mounted on his left thigh, the Spartan was the image of the idiom of armed to the teeth.

His armor itself was now armed with a weapon system taken from War Machine's systems and modified to fit the MJOLNIR armor. The Grindell/Galilean weapon project of Cortana and Stark was incomplete, so an M134 took its place for now. His armor's newly installed repulsors doubled as a weapon of last resort. Spartan 117, savior of humanity was either the best ally to have in combat or the absolutely worst enemy to engage in his standard armor, but now he was a one man army to the point of excess. However, with the task he had been given it might have all been warranted.

He was to punch a hole in the Chitauri air defenses, leading a charge of Special Forces operated Iron Man systems and Avengers. The vanguard would be closely followed by conventional forces, mainly the national guard, and the special forces coalition would move in to rescue prisoners and other civilians. Once John was done making sure that the mammoth carbine was cycling round through, for the third time, he turned around and addressed his group.

"Ladies and Gentlemen, let's take back New York. Watch each other's back and stay sharp." The UNSC warrior said before boarding a Quinjet. He was followed closely by the Iron Man armored operators decked out with rifles and machine guns with grips they could grasp through the gauntlets of the armor. They were going to be jumping off outside of the AA perimeter and flying the rest of the way in under Cortana's guidance. The Quinjet took off the Helicarrier tarmac closely followed by two more, all carrying Iron Man wearing Special Forces members. The silent and anxious flight to City was over after roughly twenty minutes, as the Helicarrier was 270 miles away and closing in so it could provide long-range fire support and resupply for the various air assets involved in the battle. The Quinjets shook from concussion waves of exploding Chitauri AA fire, the blue bolts blossoming into pale blue explosions a safe distance away from the jets. The Quinjets banked sharply to the left, in sync and engaged their VTOL systems. The jets hovered in the air, occasionally shaking as concussive blasts caused turbulence. The operators aboard the jets waited with professional calm for the green light when the Quinjets lowered their ramps. When the green lights came, the operators surged forward in neat orderly fashion some whispering prayers, other crossing Hail Mary's as they leaped from the drop ships.

As they fell, they glided into Delta formations. Falling in synchronization, they engaged their flight systems and rocketed towards the Chitauri flack, trusting in Cortana's capabilities to safely get them to the ground safely. The AI took over control of the formations and scattered the individual soldier, swiveling them around the plasma bolts and explosions with precision informed by real-time sensor readouts and satellite imagery of the AA emplacements. Their landing zone was the Battery Park area of Manhattan, taking the area would open up a shoreline that the coalition could steamroll the Chitauri from.

When they made it to the ground the Operators unslung their rifles and stormed off to their individual squad objectives, splitting into fireteams as they went. They were in their element now and didn't need to be babysat. Sierra 117 was tasked with taking out the heaviest concentration of hostiles and AA emplacements. He rocketed away using his armor's thrusters to roar over the ground to his objective. His AI partner was with him now, manning his M134 and blasting Chitauri into ribbons of dark blue flesh as he passed groups of alien soldiers. When he reached his objective area, the Financial District, he paused to assess the situation. The Chitauri had leveled the surrounding towers, except for one where they had made walls out of the wrecks of vehicles, rubble blocking off approach to the skyscraper that had been bastardized by the Chitauri. The AA gun emplacements were gouged out of the side of the building towards the top of the skyscraper and bodies were hung from windows randomly. The Chitauri had created a kill zone around this perverted citadel and in the process killed hundreds perhaps thousands. Heavy weapons were manned by the Chitauri on top of the wall of detritus and their aircraft were scrambling to the air. The weird jet-ski/ chariot crafts were the only force in the air for now, but once the vanguard had finished their task, they would be smacked down for their impudence. In order to clear the way for friendly air support, the Spartan needed to clear this Chitauri stronghold.

John had seen enough. Despite the kill zone, the Chitauri had created, they had neglected to create some cover for their gunners. The Chitauri manning the weapons that enforced the isolation of the Citadel were vulnerable. Shouldering the Chimera the Spartan sighted in on one of the Chitauri guns. With a bark, the rifle spat out a .70 caliber round and the bullet streaked through the air and ripped the Chitauri soldier's upper away from the rest of him after striking his head. Another round pierced the Chitauri antipersonnel cannon and penetrated its ammo reserves. The cannon blew up and the shrapnel cut down two Chitauri grunts standing nearby.

Before the bodies had fallen, John was firing at the next turret. The Chitauri cannon was destroyed first and the plasma stored in the weapons blew. The uncontained plasma consumed the gunner in a crackling explosion that ignited an area of several meters through sheer heat. The third turret was disabled in a burst that simply destroyed the cannon's barrel, rendering it unsafe to fire, hopefully. The Chitauri that had been behind the gun tried to escape the sights of the Spartan, but the next round sent downrange cut it in half at the small of its back. When it fell in half it was apparent the Chitauri were aware of the general direction of fire. The cannons yet to be eliminated tried to turn their sights on the Spartan, but their weapons couldn't keep up with the sprinting super soldier as he made for the wall. Plasma bolts struck the ground seconds after the Spartan had passed. Some of the more competent Chitauri were trying to get a lead on him, their bolts simply were too early or were just plain dodged.

The Spartan was easily able to avoid the lances of plasma under the effects of Spartan time. The slower moving bolts had a lower velocity than the Covenant's weaponry, a lower rate of fire also. John had nearly thirty years experience avoiding Covenant weaponry, the Chitauri cannons, and personal weapons were essentially Plasma muskets in comparison to the equipment the Covenant fielded. Despite their slower rate of fire, it was clear the Chitauri cannons were deadly. A shot impacted on an SUV that had been razed and sublimated a majority of the vehicle. This just confirmed that the Chitauri, despite their poor weapon performance, were still lethal if given the opportunity.

Chief wasn't letting any of the bolts hit him and bobbed underneath one that had been fairly on target. His retaliatory shot ensured that the Chitauri wasn't going to have another shot. Fourteen meters to the wall and John would be inside the compound. Already the Chitauri couldn't get even aim at him because he had made past their field of fire. The Spartan leaped over the wall, aided by his thrusters and began cutting down Chitauri. At first, the alien invaders had been all bravado, but after their numbers were diminished and the blood and viscera of their brethren coated them the bravado turned into terror.

One charged forwarded in the panic, too terrified to even consider shooting him, the alien tried using its rifle as a spear to stab the Spartan to death. John used his left hand to grab the Kerambit on his right and charged into the alien where its long pike rifle was no use. With a flash the Chief cut the extraterrestrial jugular artery equivalent and jerked up, slicing through its jaw bone and up into its nasal passage and lower brain cavity. The almost black blue blood splurted out of the gash and splashed the Spartan. Blood dripping down his front the Spartan sheathed the Kerambit and moved further into the Citadel, stalking his prey and objective. The Chitauri left standing had fled into its halls seeking sanctuary from the demon ravaging their forces only for the predatory warrior to pursue them.

The Master Chief swapped out his magazine for a clip of shotgun shells. When he turned the corner the Chimera roared as he pulled the trigger and held it down, stalking forward as the Chitauri tried to flee. Each shell shredded the mass of aliens, and the clip had twenty-four shells to gnash them with. Once the last shell was expended, and the last body fell the spartan stood ankle deep in biological material from forty former Chitauri who had panicked at the sheer force that they had been attacked with. Silence fell upon the atrium, only to be broken by the click of a changed clip and the snap of a charging bolt being pulled back. The Spartan located the stairs and only then did he speak.

"Cortana, where are the AA guns? And what should I expect in terms of numbers?" He inquired.

"The guns are on the East and West sides of the tower on the 50th floor. High enough to have a good field of fire, but not high enough to be exposed to strikes. In terms of guards, perhaps two hundred maybe three between you and the guns. It would be easier to take out the tower from the bottom, some charges on the support frame and you can bring it all down in one fell swoop."

"That sounds better than storming up 50 floors and killing everything on them to disable the guns. I don't have that much ammo. That and I already have a couple hours of cleaning ahead of me." The Spartan joked, shaking his armored boots in humor.

"Let's get moving cowboy. Those boots aren't going to clean themselves, the sooner we're done the sooner you can start." Cortana said in an amused light tone.

Without another word, the gore splattered Spartan started down the stairs to the Basement and sub levels. Chitauri corpses mixed with human bodies in some choke points. The Spartan double-timed it through the vacant basement. When something around the corner made a noise, the Chimera was leveled and ready to fire. Only John's experience stayed his trigger finger when a human face peeked around the corner and shined a flashlight on him.

"Holy shit!" the person exclaimed before pulling back behind the corner.

"What is it?" a woman said, her voice was hollow and nearly inaudible, but the Spartan was able to pick it up.

"I don't know, it's big as hell, though. It has a big ass gun and a minigun too." The man said, voice noticeably quivering.

"Anthony, on the count of three we're going to lay down some fire, Vanessa darling, you need to run, we'll buy you time. Hymie keep her safe. I love you honey." a different voice said, this one was calmer and collected than the others.

"Sure thing boss." The voice that John assumed to be Hymie said.

"Wilson I love you. If I never see you again I want you to know that you're a good man. If we make it through this I want to spend the rest of my life with you, just the two of us." the woman, presumably Fisk's wife Vanessa, said. Her voice was choked with tears.

"On the count of three Mr. Fisk."

"I love you," Wilson Fisk said," and if we make it through this I'm giving it all up. Just us, no more crime syndicates, just us." Fisk said his voice strained with love.

Anthony began counting down, his voice more resigned than it had been previously. It was apparent that he was expecting to die "Three. Two…".

John spoke up,"Firing on me will be the last thing you do, I suggest you safety your weapons. I'm affiliated with SHIELD."

"Don't shoot Tony. Hymie, false alarm." a mountain of a man stepped out into the open. His white business coat was splattered with blood and torn. He had an M249 in his beefy hands. His face was burnt and bloodied.

"How many people do you have with you?" Kingpin asked.

"I'm the only one in the building, but we landed 60 Special Force operators in Iron Man systems to eliminate other Anti-Air positions. When the air defenses are down we're going to be launching a major offensive."

"I think I could help you guys out with that, my people could provide extra support, but you have to get my wife and I out," Fisk said with determination in his eyes as he tried to negotiate a way to safety for his wife and himself.

"That's agreeable, but I have to set charges to level the building. There's too many Chitauri in between the guns to fight effectively."

"I know where the support columns are. I can show you where they are if you want?"

"Help is always appreciated. Have any Chitauri come down here?"

"They tried, but we kept them out. Lost a few guys."

"You're leading, but I'm on point."
