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

Battle For Earth Part 2

Back at the gas mine, the elites male their way to the entrance.
"We are the arm of the Prophets Arbiter, and you are the blade, be silent and swift, and we shall quell this heresy without incident, the storm has masked our approach, and it should have their local Battle-net in disarray, we have the element of surprise... for now", said Rtas.
"Engage active camouflage, reveal yourselves only after the Arbiter has joined battle with the enemy", said an elite.
The grunts and elites fade into their surroundings as their active camouflage is engaged.
"You may wish to do the same, Arbiter, but take heed: your armor's system is not as...new as ours, your camouflage will not last forever", said Rtas.
Arbiter activated his camouflage and the whole group snuck in.
Meanwhile on earth, Master Chief and everyone else ran through a small area in a partially damaged building and shot a few grunts in the way.
"Master Chief is clearing this tiny area for us but a bigger wave is coming once we enter this area", said Armatenant.
"Don't these kids seem familiar", asked a marine.
"Focus, here they come", yelled another marine.
A wave of covenant appeared showing grunts, elites and jackals.
Bakugo charged up his quirk.
"TASTE MY WRATH INVADERS", yelled Bakugo.
Bakugo leaped forward and started blasting groups of covenant.
Everyone started shooting at other groups.
Kirishima hardened himself to block most of the blasts.
An elite got close to him but was easily knocked out by a red gauntlet punch.
Kirishima saw more covenant coming from a distance.
"There's another wave coming", yelled Kirishima unhardening.
Master Chief pulled out his battle rifle and shot down several grunts and elites.
"There's more over there", said Yaoyorozu shooting another group of covenant behind Kirishima.
"For a small fleet, there's a lot in this area", said Master Chief.
"If they didn't know we're here before, they do now", said Johnson on a communicator.
"No kidding", said Cortana.
A swarm of buggers came flying in.
"Yep, here they come, up high, buggers headin' over the rooftops", said Johnson.
"Dark Shadow I could use some help up their", said Tokoyami.
He and Dark Shadow used the black fallen angel technique to take out the buggers.
There were still too many of them in the air.
Deku decided to use black whip to swing himself off of buildings to get himself into the air.
He used his assault rifle and swung off of buildings at the same time to take out the buggers.
Master Chief found a machine gun and helped Deku and Tokoyami take out the buggers as well as shooting move covenant on the ground.
One of the buggers latched onto Deku causing him to fall.
Deku grabbed hold of the bugger and turned it towards the ground slamming it into the concrete.
"You okay kid", asked a marine.
"Yeah, I'm okay", answered Deku out of breath.
"Eyes up, phantom's back", said Johnson in a communicator.
A phantom came in and dropped off another wave of covenant.
"Everyone take cover", said Todoroki.
Todoroki came in and froze the group of covenant.
Then Bakugo blew it up taking out a mass amount of covenant.
"Not bad", said Master Chief.
"Look out, plasma grenades", yelled a marine.
A plasma grenade was thrown near Deku and jumped away as fast as he could.
"Carful, those grenades stick", said Armatenant.
"Yeah no kidding", said Deku.
Todoroki blocked the grenades with his ice giving the marines a chance to shoot them all down.
Another Pelican arrives hovering over the courtyard.
"My girl's a little big for that courtyard, sergeant, I see a good LZ on the other side of these buildings, meet you there, over", said the pilot on a communicator.
"Copy that, someone get a satchel on the gate", said Johnson.
"Forget that, I can just use my.....", said Bakugo.
Before anyone gets a chance to reach for a satchel or Bakugo using his quirk, the gates break and a pair of hunters arrive.
"Hunters", said Cortana.
"Stand back marines, let the Chief show you how it's done", said Johnson.
"That means you too volunteers, some of these Marines are new here and they need to learn", said Armatenant.
Chief used the machine gun and damaged both hunters.
The gun ran out of ammo and he decided to jump down and pulled out his SMG.
The hunters were shooting their blasters and charged at Master Chief.
He aimed for an opened area and threw a plasma grenade he found at it gravely damaging the humter.
Chief shot at the other and rolled away to his right after another charge.
He finished off the badly damaged hunter and leaped onto the other one.
He stuck another plasma grenade he found onto a gap and leaped off.
The second hunter was soon down after the grenade blew up.
"You weren't kidding about him being strong", said Kaminari.
"Told you", said Jonny.
"You see what Chief did there, he damaged the inside of them, not the armor, you guys will get a chance to take on them next time, now I'm sure you will have you own ways to take out the hunters knowing your quirks, but keep in mind their blasters can break out of traps if they have a chance (eyeing Todoroki)", said Armatenant.
"Understood sir", said Todoroki.
Cortana started talking to another squad on a communicator.
"Second squad this is Cortana, what's your status, over", asked Cortana.
"We're operational ma'am... barely, our pilots didn't make it", answered Gunnery Sergeant Marcus Stacker.
"Find a hole, stay put, we'll come to you, (to class A) you coming volunteers", asked Cortana.
"Yes ma'am, or digital lady", answered Iida.
"This way", said Master Chief.
Cutting back to the gas mine, the covenant snuck around listening to the heretic elites talk to one another.
"Any word on our missing brothers", asked H Elite 1.
"Still nothing, given what we have learned, I fear they are lost", answered H Elite 2.
"Maybe the Oracle will protect us...", said H Elite 1.
"Perhaps, but his sentinels are too few, better we protect ourselves", said H Elite 2.
Arbiter threw a plasma grenade in between the heretic elites.
"What the", said H Elite 1.
The grenade blew up not killing them but severely damaging their armor.
Then he jumped in slashing them both with his energy sword.
The heretic grunts spotted him when his camouflage went down and started shooting.
But they were taken out quickly by the elites loyal to the prophets.
The army leaped across to the blue energy looking conveyor belts taking out more of the heretic army.
After passing the conveyor belts, Arbiter approached an elevator and turned his camo back on.
He snuck around shooting the H grunts with his Type-51 Carbine.
An H elite snuck up behind Arbiter only to get whacked.
He and the team took the elevator and descends into a hangar containing a Seraph.
The hangar contained flying bots.
"Sentinels, the holy warriors of the Sacred Rings, why have they sided with these heretics", asked an elite.
"Arbiter, clear the hangar and open this door, so I may drop the second Lance", said the phantom pilot.
The sentinels shot out long beams at a few elites.
They shot down the sentinels with their Carbines as well as the Arbiter.
The heretics were soon shot down and sliced clearing the hangar.
Arbiter opens the door.
"Hold position, I am making my approach".
A phantom flew in dropping of more elites.
A door opens on the opposite side of the hangar.
Arbiter ran through some hallways taking out more of the heretic army along the way.
"There he is, a believer of the prophets", said an H elite.
Arbiter dodged the blasts and shot down the rest of the army in the halls.
He entered another area with more heretics and sentinels.
After they were taken down, Arbiter has reached a room with the heretic leader Sesa 'Refumee and three banshees on the other side of the glass featured wall.
"Deal with him, my brothers, I will defend the Oracle", said Sesa.
More heretics entered the room surrounding Arbiter.
"We have you now, time to blast into smithereens", said an H elite.
"Crap", said Arbiter.
They all shot but Arbiter survived by bending backwards and dodging the blasts matrix style.
Most of the group ended up killing each other by mistake leaving Arbiter blasting the rest on his own.
More Sentinels appeared shooting their beams.
Arbiter was out of ammo and picked up two plasma rifles.
He shot them all while jumping and rolling dodging all of the beams.
Soon all of the sentinels blew up and their parts came crashing down.
"The heretics are mobilizing their air forces Arbiter, get after their leader, but watch your back, I'm sending one of our Phantoms to support you", said Rtas on a communicator.
"I'm on my way", said Arbiter.
Arbiter reached a door that took him to the other side of the glass and took off in a banshee.
"His truth must not be silenced", said H Elite 3.

In case you don't know what H is, it means heretic. I used it to shorten up the chapter a little bit.
