Cap: What's the story upstairs?
Thor: The power surrounding the cube is impenetrable.
Iron man: Thor is right. We gotta deal with these guys.
Black Widow: How do we do this?
Cap: As a team.
Thor: I have unfinished business with Loki.
Hawkeye: Yeah, get in line.
Cap: Save it. Loki's gonna keep this fight focused on us and that's what we need. Without him these things could run wild. We got Stark up top, he's gonna need us...
Just then, Bruce arrives on a moped. Getting off, he looks around the city.
Bruce: So, this all seems horrible.
y/n: Nah, hold me back!
Black Widow: I've seen worse.
Bruce: Sorry.
Black Widow: No. We could use a little worse.
Cap: Stark? We got him.
Iron man: Banner?
y/n: Just like you said.
Tony: Then tell him to suit up. I'm bringing the party to you.
Iron man comes out from behind a building. The Chitauri leviathan follows, impatiently. The rest of the Avengers look up, getting ready and standing still.
Black Widow: I... I don't see how that's a party...
y/n: You obviously haven't had enough to drink.
Black Widow: And you have?
y/n and Clint warily glance at each other.
y/n: No...
Iron man swoops down the street. The leviathan also swoops down, barreling down the street like a freight train that keeps building and building its intensity. Banner looks behind. Cap looks at him. Banner begins to walk towards the monster.
Cap: Dr. Banner. Now might be a really good time for you to get angry.
Bruce: That's my secret, Captain. I'm always angry.
Banner's body starts to swell and stretch and harden. green veins highlight around his neck... Hulk. Aaaannndddd.........SSSMMMAAASSSHHH!!!! Hulk pops the beast in the nose. The creature flips over and lands on it's back. Iron man, in mid-flight, extends his arm out and a rocket, ready to shoot. Iron man fires- the rocket hits a soft spot, multiple leviathans are blown away. Other pieces of the main leviathan catch fire and withdraw... they sizzle as they hit the pavement. Cap and y/n raise their shields to block them. From above and on the buildings, the Chitauri army watch in horror as a group of earth's mightiest heroes find themselves united against a common threat. To fight the foes no one single hero could. Loki watches below, emotionless.
Loki: Send the rest.
From the portal, thousands more soldiers fly out.
Black Widow: Guys.
Iron man: Call it, Cap.
Cap: Alright, listen up. Until we can close that portal up there, we're gonna use containment. Barton, I want you on that roof, eyes on everything. Call out patterns and strays. Stark, you got the perimeter. Anything gets more than three blocks out, you turn it back or your turn it to ash.
Hawkeye: Wanna give me a lift?
Iron man: Right. Better clench up, Legolas.
Iron man lifts Hawkeye up to the building.
Cap: Thor, you've gotta try and bottleneck that portal. Slow them down. You've got the lightning. Light the bastards up.You and me, we stay here on the ground, keep the fighting here. And Hulk... smash.
The Hulk grins, and leaps- soaring high into the air. He dives towards a building- throwing dead Chitauri behind him. Some soldiers fire at him- but are quickly backhanded. With his most powerful leap yet- Hulk ascends right into the fray of leviathans and chariots which he smacks out of altitude. Thor grabs onto the tower. Raises mjolnir and lightning strikes down from above, colliding on mjolnir. Thor aims the massive shockwave towards the portal. He channels the blasts and fires at soldiers emerging from the portal. The Chitauri convulse, dropping dead to the ground. Back on the bridge, Fury sees on his viewscreen the destruction going on in New York. Agent Hill walks up to him.
Maria: Sir. The council is on.
Atop the rooftop, Hawkeye fires arrows into the streaming flow of the chariots, hitting his mark each time. Hell, he even aims his bow behind him, without looking and releases the arrow, exploding a rider.
Hawkeye: Stark. You got a lot of strings sticking to your tail.
Iron man: Just try and keep them off the streets.
Hawkeye: Well, they can't bank worth a damn. Find a tight corner.
Iron man: I will roger that.
Iron man does so and leads towards tight corners and in Hawkeye's view, who fires arrow upon and arrow, exploding the riders. Iron man keeps leading riders under tunnels. He looks back. None left.
Tony: Nice call. What else you got?
Hawkeye: Well, Thor's taking on a squadron down on 6th.
Tony: And he didn't invite me?
Black Widow, using the energy rifle, is taken off her feet by a soldier. She tiresomely takes it down by cutting its throat. She grabs the energy rifle, turns to attack. Cap and y/n stand there, holding their shields. She slumps back, tired.
Black Widow: Captain, none of this is gonna mean a damn thing if we don't close that portal.
Cap: Our biggest guns couldn't touch it.
y/n: What is it with me and portals?
Black Widow: Well, maybe it's not about guns.
Cap: You wanna get up there, you're gonna need a ride.
Black Widow: I got a ride. I could use a lift though.
Black Widow backs up giving herself a running start. Cap lifts and angles his shield
Cap: Are you sure about this?
Black Widow: Yeah. It's gonna be fun.
Black Widow runs at Cap and propels. herself off of his shield, y/n uses his jet boots to catch Nat before flying up and letting her leapfrog off of him, catching herself on a chariot. y/n starts to fall and catches himself last second with his grapple. Widow climbs onto the chariot and cuts the turret shooter's linkage to it. She then jumps on the rider and sticks her knives into his nervous system. She gets him to bankover a building. Iron man arrives and shoots any other Chitauri following her. He makes his way down to Cap and y/n, who fight off more soldiers. Iron man points his repulsors at Cap's shields which Steve reflects. y/n chuckles at them since he can do that on his own. From above them, Hawkeye sends down remaining arrows. He sends one across the street, taking down a rider following Tony. Finally, we have Thor and Hulk fighting on top the back of the leviathan, tearing apart and fighting soldiers. Hulk breaks off a bit of it's armour and stabs it into it's spine. Summoning all his strength he, Thor brings down the leviathan with the final blow. The leviathan crashes into a history museum. Dead. Thor and Hulk stand on the back of the leviathan after bringing it down. They stand still, admiring. Hulk punches Thor for seemingly no reason- he goes flying. Selvig finally wakes from Loki's mind control. He looks around, confused where he is. He looks up at the sky, amazed.
Several humvees aim their mounted .50 Cal guns into the sky, firing and hitting riders. Cap fights off a soldier who is pinning him down with its energy rifle. Cap breaks it's leg and y/n vaporises it. He stands up, picking up his shield
Hawkeye: Captain, the bank on 42nd past MADISON, they caught a lot of civilians there.
Cap and y/n: We're on it.
