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

The Wall

In the first room, there are some Constructors repairing an entrance.
After the Arbiter jumps into the passageways moving downward, and the first room, he meets a Grunt, who greets him.
After the Arbiter enters the next room, he finds a group of Grunts and Jackals fighting Sentinels.
"Arbiter... our savior (pause) stupid Jackal, say thank you", said a Grunt.
"I was about to", said a Jackal.
"Don't thank me now, we have work to do", said Arbiter.
After he defeats the Sentinels and cuts off any more from entering, he moves into the next room.
"(COM) You're getting close to one of the shield generators, many of my Brutes have fallen attempting to take it down, let's see if you fare better", said Tartarus.
A Grunt runs towards him in fear.
"Big, scary thing, run away", yelled the Grunt.
"Don't let the others die because of your fears", said Arbiter stopping the Grunt.
"Please, don't make me go back", said the Grunt scared.
"Joshua does his best to train excellent warriors into the battle field, he wouldn't be pleased if you just run, that training would be a waste of time, you can take on whatever's in there it's not that tough", said Arbiter.
"You really mean that", asked the Grunt.
"Trust me, those lasers don't blast through very deep", answered Arbiter.
"You hear that giant sentinel, you're going down", said the Grunt running back in the room.
"I think the other Grunts should be encouraged more to make them a little braver", said Arbiter.

Arbiter reaches the Shield Generator
"

(COM) You've reached the power source, Arbiter", said Tartarus.
An enforcer descends from above
"Their that's the giant sentinel", said the Grunt pointing to the enforcer.
"That thing has a shield, we need to aim for the back", said Arbiter.
The sentinel started shooting lasers.
"(COM) It is useless to attack the Enforcer at the front, especially when its shields are up, stay in the shadows, wait until it loses interest, then strike the beast when its back is turned", said Tartarus.
"He just told me my plan, so petty", said Arbiter.
"(COM) I HEARD THAT JACKASS", yelled Tartarus.
"(To the Grunt) stay in the shadows, then shot it when it turns it's back", said Arbiter.
Arbiter and the Grunt hid in the shadows.
When the enforcer lost interest and turned it's back they shot off the legs then Arbiter slide underneath and threw up a plasma grenade on it.
It exploded destroying the enforcer.
"(COM) Nice work Arbiter, overload the locks holding the power source in place", said Tartarus.
"Hey Grunt, can you push those two locks for me", asked Arbiter.
"Okay", said the Grunt.
Arbiter pushed one of the locks while the Grunt struggled.
"Just tap it", said Arbiter.
The Grunt tapped it and it was overloaded.
"I did it, it worked", said the Grunt excitedly.
"Great, now go overload the other one", said Arbiter.
"Yes Arbiter", said the Grunt.
They pushed the last two locks and a holo-panel appears.
"(COM) Release the power source, now, find a way to remove it from its cradle", said Tartarus.
Arbiter uses the holo-panel.
The platform starts moving and the door in front of him opens.
The Grunt hugs the Arbiter's leg in fear.
Arbiter looks up, and sees the bright-green shield surrounding the Library fading away, followed by Tartarus' Phantom flying lower towards the other side of the wall.
"(COM) Our path to the Library's clear, I'll pick you up on the ledge ahead", said Tartarus.
Meanwhile some pelicans containing Armatenant's and Donald's squad started flying over the wall.
"Finally, you on your way with the other volunteers", asked Donald.
"(COM) Yes I am, they have killed the Prophet Of Regret but Master Chief is missing", said the pilot with Deku's group.
"What happened", asked Donald.
"(COM) All I know is a huge purple beam fired on the temple, I wouldn't say he's dead but I found everyone in the water except him", answered the pilot.
"Do you think he's okay", asked Kaminari.
"He's Master Chief, he'll turn up eventually", answered Todoroki.
C

uts back to Arbiter and the Grunt.
"You have a name Grunt", asked Arbiter.
"Cody", answered Cody.
"Cody, you're hurting my leg", said Arbiter.
Cody let go of Arbiter's leg.
"Sorry", said Cody.

The door of the approaching wall opens to another enforcer firing on the phantom.
"

(COM) (growls) Blasted machines, make your own way through the wall, Arbiter", said Tartarus frustrated.
The Phantom leaves, followed by an attack by sentinels, sentinel majors and a break-out of flood combat forms.
Arbiter blasted the flood and Cody took down the sentinel.
Then they destroyed another enforcer together.
They traveled through hallways battling flood.
Cody was able to kill a flood combat form all by himself.
"Not so tough are you flood", said Cody.
"Don't get overconfident Cody, death is still possible", said Arbiter.
"Oh yeah, right", said Cody.
Arbiter COM link picks up a Marine's transmission.
"(COM) Proceed to the objective, we'll hold out as long as we can, (screams painfully) get it off me", screamed a marine sargent.
"(COM) Suppressive fire, suppressive fire", yelled a marine.
"What was that", asked Cody.
"Sounded like a transmission from the humans, I think they're being attacked by these parasites", said Arbiter.
A combat form flood leaped on Cody.
Arbiter shot it and pushed it off.
"Whaaa, there's more", yelled Cody pointing to flood behind them.
"Stay close to me, there's a lot of them", said Arbiter.
They blasted flood as the ran down the hallway.
Cody even tried a shotgun he found by a dead marine despite his small body.
They eventually reached another bottom floor and Arbiter heard a marine transmission again.
"(COM) Negative, ma'am, they are not covenant", the marine sargent.
"(COM) Cover that doorway", said the marine.
Arbiter and Cody fights through hordes of Flood, Sentinels and Enforcers.
Cody starts getting a little better at fighting and grows more confident.
They finally dropped down to a long tunnel, and reached the bottom of the wall.
A

s soon as the doorway opens, an airborne Sentinel manufacturing facility can be seen in the distance as it is shot down by wraith mortars and crashes into the Quarantine zone.
Arbiter and Cody proceeds through the snow.
Orbital Insertion Pods land across the canyon.
"Forerunners be praised, the Arbiter", said elite 1.
With the Elites' assistance, they defeated small waves of Flood.
"This Quarantine Zone has been compromised, we must do what we can against the flood, our commander has landed further in, let us join him", said elite 2.
Everyone crosses a bridge and through a tunnel, and meets the Spec Ops Commander, Rtas 'Vadumee.
"(Surprised) Arbiter, what are you doing here", asked Rtas.
"Tartarus couldn't pick me up so .....", answered Arbiter.
Arbiter is interrupted by screeches of the Flood.
"The Flood is upon us", said an elite.
"We must hold this camp until reinforcements arrive", said Rtas.
"Bring on the fight", said Cody.
"I see you have a Grunt with you", said Rtas.
"He's been following me the whole time, but he just need some encouragement", said Arbiter.
After the fight has gone on for a while, a Phantom descends from above, firing on any remaining Flood in the zone.
Eventually the phantom flies away after shooting the remaining flood.
Arbiter and Rtas are talking on the snow below.
"In the center of this zone is a Sacred Icon critical to the Great Journey, I must find it", said Arbiter.
Rtas nods.
"(Clenches his fist) We shall cut into the heart of this infestation, retrieve the Icon, and burn any Flood that stand in our way", said Rtas.
Elites roar and growl in agreement.
"For the Great Journey", yelled Cody in excitement.
"(to Arbiter) The parasite is not to be trifled with, I hope you know what you are doing", said Rtas.
Arbiter looks to his left at the entrance ahead.
