Invasion Of Two Army's (Mha X Halo Crossover)

Prologue

A ship was flying through a cloud of dust.
"I do not trust you", said a voice.
There were aliens and people in suits of futuristic armor.
"He may but I do not", said an alien.
"Noted", said the Spartan.
"My friends trust is not the issue today, Spartan Locke, it is my trust you must earn", said another alien walking in.
"Arbiter", said Spartan Locke.
"You are a hunter yes, a seeker of things", said Arbiter.
"That's not the official job title, but it's close enough", said Spartan Locke.
"And now you hunt other Spartans", said Arbiter.
"I'm not so much hunting a Spartan, as I'm hunting the Spartan", said Spartan Locke showing a holographic image of a certain Spartan.
"You seek", said Arbiter.
"One one seven", said Spartan Locke.
"I was not told the identity of your prey", said Arbiter.
"That is why I'm sharing it with you now, we're talking about trust after all", said Spartan Locke.
"May I ask you something, your people used to call him demon, is that an insult or a compliment"?
"An insult to be sure, but one with a modicum of respect, he was indeed my enemy, but in time, I named him ally, even friend, as well as a couple of teenagers with superpowers", said Arbiter.
"What teenagers are you referring to", asked Spartan Locke.
"They were students from a heroics school down on Earth, they were his respected allies eradicating our enemies by his side in the war, they were strong and brave, especially that kid with the green hair, he had a real passion of being Earth's protector, he was a kindhearted kid who always puts others before himself, and he wants to help people with a smile on his face, he gives it everything, now the events that forged these bonds were........ complicated", said Arbiter.
A large ship was flying by destroyed installation 04 to a large mobile planetoid station Called High Charity, also known as the capitol named the Holy City of the Covenant.
Inside there were covenant in a throne room/court room gathered in their seats and three prophets in their gravity thrones scolding an elite. One of the prophets was in a holographic projectile while he was somewhere else.
"There was only one ship", said Arbiter.
"One, are you sure", asked the Prophet of Truth.
"Yes, they called it, The Pillar of Autumn", answered Arbiter.
Everyone got angry.
"Why was it not destroyed with the rest of their fleet", asked The Prophet of Mercy angerly.
"It fled, as we set fire to their planet but I followed with all the ships in my command", answered Arbiter.
"When you first saw Halo, were you blinded by it majesty", asked The Prophet of Regret.
"Blinded", asked Arbiter.
"Paralyzed, dumbstruck", asked Regret.
"No", answered Arbiter.
"Yet the humans were able to evade your ships, land on the Sacred Ring and desecrate it with their filthy footsteps", said Regret.
"Noble hierarchs, surely that once the parasite attacked...", said Arbiter.
Everyone booed him before he can finish.
"There will be order in this council", yelled Mercy.
"You were right to focus your attention on the flood, but this demon, this Master Chief...", said Truth.
"By the time I learned the demon's intent, there was nothing I could do", said Arbiter.
Everyone booed again.
"He's a traitor", said a covenant.
A brute slightly laughed at his shame.
"Noble Prophet of Truth, this has gone on long enough, make an example of this bungler, the Council demands it", whispered Regret.
"You are one of our most treasured instruments, long have you have led your fleet with honor and distinction....but your inability to safeguard Halo was a colossal failure", said Truth.
Everyone booed again.
"Nay, it was heresy", said a covenant.
"I will continue my campaign against the humans", said Arbiter.
"No you will not", said Truth.
The brutes took Arbiter away.
"Soon the Great Journey shall begin...but when it does, the weight of your heresy will stay your feet....and you shall be left behind", said Truth.
Meanwhile a ship flew to a Earth Defense Platform, the Cairo station.
"The plating was about to fail, there's viscosity throughout the gel-layer, optics, totally fried, and let's not even talk about the power supply, you know how expensive this gear is son", asked Master Gunnery Sergeant.
Master Chief put on his helmet.
"Tell that to the Covenant", said Master Chief.
"Well, I guess it was all obsolete, anyway, your new suit's a Mark VI, just came up from Songnam this morning, try and take it easy till you get used to the upgrades", said Master Gunnery Sergeant.
"I'll take it easy once the covenant is finally finished", said Master Chief.
"Fine, but don't come cryin' to me when you rip your leg out of it's socket", said Master Gunnery Sergeant.
"Okay I'll test my upgrades if that makes you happy", said Master Chief.
"Okay, let's test your targeting", said Master Gunnery Sergeant.
Earth:
Meanwhile, something was heading towards Earth.
It landed near the beach of Musutafu, Japan.
Cairo station:
"Tracking looks sketchy, I'm gonna run you through the full diagnostic, the diagnostic software sets your targeting system to be normal, go ahead and look at the four lights, Chief, you want me to leave it like that, or make it inverted"?
"I'm curious on what inverted does", said Master Chief.
Gunnery Sergeant helped Chief select inverted.
"Okay, now it's inverted, go ahead and target 'em one more time", said Master Gunnery Sergeant.
Earth:
On earth, Endeavor saw smoke coming from the beach.
"You clean up this mess, I'll go check out that smoke over at that beach", said Endeavor.
Cairo station:
"Should I leave it inverted, or put it back to normal"?
"I think it was better normal", said Master Chief.
Gunnery Sergeant switched his tracking back to normal.
"Okay, now it's back to normal, I'll leave your targeting set to normal, if you change your mind, you can switch the setting anytime", said Master Gunnery Sergeant.
"Yes sir", said Master Chief.
"Stand by, I'm gonna offline the inhibitors, move around a little, get a feel for it, when you're ready, come and meet me by the zapper", said Master Gunnery Sergeant.
Earth:
Endeavor and Hawks checked out the object at the beach.
It turned out to be a damaged spaceship covered in a parasitic substance.
"What is this", asked Hawks.
"I don't know, but it doesn't look like a meteorite", said Endeavor.
Hawks knocked on the ship.
"It could be a spaceship from....." said Hawks.
The door slide open and revealed a bunch of infested areas.
"Whatever this stuff is it's turned it into some sort of nest".
"I think we should let Tsukauchi see this, he might be able to....." said Endeavor.
Suddenly, a tiny parasitic creature jumped out at Endeavors face.
"AHHHHHHHHHH, GET IT OFF ME"!
Hawks pulled it off then Endeavor smashed it with a piece of the ship over and over.
"Okay okay I think you've got it, chill", said Hawks.
"What the hell was that thing, it was trying to feed on me, like a leach", asked Endeavor.
Then more came out of the ship.
They started attacking them with their quirks.
Then an elite infested by the parasite walked out of the ship.
"This looks like and undead infestation Endeavor", said Hawks.
"Yes I see that", said Endeavor.
Cairo station:
"Pay attention, 'cause I'm only going over this once, this station'll test your recharging energy shields, step on in, I'll show ya", said Master Gunnery Sergeant.
Chief stepped in.
"Go ahead and press the red switch to start the shield test".
He activated the red switch.
"Bingo, as you can see, they recharge a lot faster".
Someone stepped in from the elevator.
"If your shields go down, find some cover, wait for the meter to read fully charged".
"That, or he can hide behind me, you done with my boy here, Master Gunns, I don't see any training wheels", asked the man.
"His armor's working fine, Johnson, so shut your chili-hole, you're free to go, son, just remember, take things slow", said Master Gunnery Sergeant.
"Don't worry, I'll hold his hand, c'mon Chief, they're waiting for us on the bridge", said Johnson.
Master Chief followed Johnson in the elevator.
"So, Johnson, when you gonna tell me how you made it back home in one piece", asked Master Gunnery Sergeant.
"Sorry Gunns, it's classified", answered Johnson.
"Huh, my ass, well, you can forget about those adjustments to your A2 scope, and you're sure as hell...", yelled Master Gunnery Sergeant angerly.
The elevator door closed and it rises.
"Well, he's in a particularly fine mood, maybe Lord Hood didn't give him an invitation", said Johnson sarcastically.
"Maybe", said Master Chief.
The elevator stopped and they walked into a tram.
The tram started moving.
"Earth... haven't seen it in years, when I shipped out for basic, the Orbital Defense Grid was all theory and politics, now look, the Cairo is just one of three hundred geo-sync platforms, that MAC gun can put a round clean through a Covenant capital ship, with coordinated fire from the Athens and the Malta, nothing's getting past this battle cluster in one piece", said Johnson.
Several UNSC ships drift past the station.
"Ships have been arriving all morning, nobody's saying much, but I think something big's about to happen".
Earth:
After Endeavor and Hawks killed the remaining creatures, they picked up some evidence for Tsukauchi.
"Quickly to the police station", said Hawks.
They ran to the police station.
"I think this should be studied at the lab", said Endeavor.
Cairo station:
Master Chief and Johnson walked out of the tram seeing a crowd of cheering marines as they walk down the deck.
"You told me there wouldn't be any cameras", said Master Chief.
"And you told me you were gonna wear something nice, folks need heroes Chief, to give 'em hope so smile would you, while we still got something to smile about", said Johnson.
A door opened and they walked in a room full of men in white uniforms.
High Charity:
The brutes walked Arbiter down a path full of booing covenant yelling heretic.
They strapped his arms into some device.
"You've drawn quite a crowd", said Tartarus.
"If the came to hear me beg, they will be disappointed", said Arbiter.
"Are you sure", asked Tartarus.
Tartarus pushed a button and the device zapped Arbiter.
Cardio station:
Lord Hood was saluting to the two men.
"Gentlemen, we're lucky to have you back", said Hood.
An officer whispers into his ear.
"Go ahead Cortana".
Cortana appears on a nearby holotank.
"Another whisper, sir, near Io, we have probes en route", said Cortana.
"I apologize, but we're going to have to make this quick", said Hood.
"You look nice", said Cortana.
"(simultaneously with Johnson) Thanks", said Master Chief.
"Thank you", said Johnson.
Hood picks up a medal.
"Sargent Major, The Colonial Cross is awarded for acts of singular daring and devotion, for a soldier of the United Earth Space Corps...", said Hood placing the medal on Johnson's uniform.
High Charity:
"There can be no greater heresy, let him be an example for all who would break our Covenant", said Tartarus.
Two brutes started pulling off Arbiters charred armor.
Cardio station:
A young woman joins Master Chief and Johnson.
"Commander Miranda Keyes, your father's actions were in keeping with the highest traditions of military service, his bravery in the face of impossible odds reflects great credit, upon himself, and the UNSC, The Navy has lost one of its best", said Hood.
He gave Keyes the Colonial Cross medal.
High Charity:
The charred helmet fell to the floor.
A glowing brand rises from the floor behind him, and Tartarus grabs it and strides forward.
Arbiter raises his head weakly. Tartarus gives him a fierce look, and presses the brand against his chest with malice.
The tortured Arbiter fights the pain but gives in and screams.
Cardio Station:
Alarms start to sound.
"Slipspace ruptures directly off our battle cluster", said Cortana.
"Show me", said Hood.
Images of Covenant ships appears on a large screen.
"Fifteen Covenant capital ships holding position just outside the kill zone", said Cortana.
The screen shows UNSC ships approaching the Covenant fleet.
"This is Fleet Admiral Harper, we are engaging the enemy", said Harper.
"Negative, Admiral, form a defensive perimeter around the cluster, (to Keyes) commander, get to your ship, link up with the fleet", said Hood.
Keyes salutes.
"Yes sir", said Keyes.
She leaves the room.
"You have the MAC gun, Cortana, as soon as they come in range, open up", said Hood.
"Gladly", said Cortana.
Her avatar disappears.
"Something's not right... the fleet that destroyed Reach was fifty times this size", said Hood.
An officer faces Hood.
"Sir, additional contacts, boarding crafts and lots of 'em", said the officer.
"They're going to try to take our MAC guns offline, give their capital ships a straight shot at Earth, Master Chief, defend this station", said Hood.
"Yes, sir, (to Johnson) I need a weapon", said Master Chief.
"Right this way", said Johnson.
Through the bay windows looking up to the MAC cannon, the fleet turns to engage the Covenant attackers. Longsword fighters hurtle overhead trailed by Marathon-class cruisers.
