I'm going to try my best to write a crossover. Please leave suggestions on what to add or change.
I don own Avengers or Newsies. The script is basically the same as in the Marvel movies but instead with the Newsies characters. You might not understand it all unless you have seen both Newsies and at least most of the Marvel movies. Also some characters aren't from Newsies and that is because there are WAY more characters in the Marvel movies than in Newsies.
4F Doctor: O'Connel, Michael. Kaminsky, Henry.
Jack Kelly: Boy, a lot of guys getting killed over there.
4F Doctor: Kelly, Jack.
Enlistment Guy: It kind of makes you think twice about enlisting, huh?
Jack Kelly: Nope.
4F Doctor: Kelly. What did your father die of?
Jack Kelly: Mustard gas. He was in the hundred and seventh infantry. I was hoping I could be assigned…
4F Doctor: Your mother?
Jack Kelly: She was a nurse in a TB ward. Got hit, couldn't shake it. [the doctor looks at Jacks's file which shows he has a long list of health issues]
4F Doctor: Sorry, son.
Jack Kelly: Look, just give me a chance.
4F Doctor: You'd be ineligible on your asthma alone.
Jack Kelly Is there anything you can do?
4F Doctor: I'm doing it. I'm saving your life. [He stamps the card 4F.]
Commercial Announcer: War continues to ravage Europe. But help is on the way. Every able-bodied young man is lining up to serve his country. Even little Timmy is doing his part collecting scrap metal. Nice work, Timmy!
Loud Jerk: Who cares? Play the movie already!
Jack Kelly:Hey, you wanna show some respect?
Commercial Announcer: Meanwhile, overseas, our brave boys are showing the Axis powers that the price freedom is never too high.
Loud Jerk: Let's got! Get on with it! Hey, just start the cartoon!
Jack Kelly: Hey buddy, you wanna shut up?!
[the guy gets up and looks at him]
Commercial Announcer: Together with Allied forces, we'll face any threat, no matter the size.
[Jack is getting beaten in an alley by the loud jerk that was disturbing everyone at the cinema]
Loud Jerk: You just don't know when to give up, do you?
Jack Kelly: I can do this all day. [and attacks the guy again]
Crutchie Morris Hey! Pick on someone your own size.
[after saving Jack from getting any further beatings by the loud jerk]
Crutchie Morris: Sometimes, I think you like getting punched.
Jack Kelly: I had him on the ropes.
[picks up Jack's enlistment form from the ground]
Crutchie Morris How many times is this?
[reading from the enlistment form]
Crutchie Morris: Oh, you're from Paramus now? You know it's illegal to lie on the enlistment form. And seriously, Jersey?
Jack Kelly: You get your orders?
Crutchie Morris: The one-o-seventh. Sergeant Crutchie Morris. Shipping out for England first thing tomorrow.
Jack Kelly: I should be going.
Crutchie Morris: Come on, man. My last night! Gotta get you cleaned up.
Jack Kelly: Why? Where are we going?
Crutchie Morris: The future.
Crutchie Morris: I don't see what the problem is. You're about to be the last eligible man in New York. You know, there's three and a half million women here.
Jack Kelly: Well, I'd settle for just one.
Crutchie Morris: Good thing I took care of that.
Connie: Hey, Crutchie!
Jack Kelly:What did you tell her about me?
Crutchie Morris: Only the good stuff.
Expo Announcer: Welcome to the Modern Marvels Paviliion and the World of Tomorrow. A greater world. A better world.
Connie: Oh, my God! It's starting!
Mandy: Ladies and gentlemen, Mr. Howard Stark!
Howard Stark: Ladies and gentlemen, what if I told you that in just a few short years, your automobile won't even have to touch the ground at all.
Howard Stark: Yes. With Stark robotic reversion technology, you'll be able to do just that.
[he turns on the switch of his machine and the car starts to hover off the ground]
Crutchie Morris: Holy cow.
[the robots making the car hover suddenly malfunction and the car falls back on stage]
Howard Stark: I did say a few years, didn't I?
[everyone laughs]
[Jack disappears, and Crutchie notices]
Crutchie Morris: Hey, Jack, what do you say we treat these girls…
Crutchie Morris: Come on. You're kind of missing the point of a double date. We're taking the girls dancing.
Jack Kelly: You go ahead. I'll catch up with you.
Crutchie Morris: You're really gonna do this again?
Jack Kelly: Well, it's a fair. I'm gonna try my luck.
Crutchie Morris: As who? Jack from Ohio? They'll catch you. Or worse, they'll actually take you.
Jack Kelly: Look, I know you don't think I can do this.
Crutchie Morris: This isn't a back alley, Jack. It's war!
Jack Kelly: I know it's a war. You don't have to tell me.
Crutchie Morris: Why are you so keen to fight? There are so many important jobs.
Jack Kelly: What am I gonna do? Collect scrap metal…
Crutchie Morris: Yes!
Jack Kelly: …in my little red wagon.
Crutchie Morris: Why not?
Jack Kelly: I'm not gonna sit in a factory, Crutchie.
Crutchie Morris: I don't…
Jack Kelly: Crutchie, come on! There are men laying down their lives. I got no right to do any less than them. That's what you don't understand. This isn't about me.
Crutchie Morris: Right. Cause you got nothing to prove.
Connie: Hey, Sarge! Are we going dancing?
Crutchie Morris: Yes, we are. Don't do anything stupid until I get back.
Jack Kelly: How can I? You're taking all the stupid with you.
Crutchie Morris: You're a punk.
Jack Kelly: Jerk. Be careful.
Jack Kelly: Don't win the war till I get there!
Crutchie Morris: Come on girls. They're playing our song.
Doctor: Wait here.
Jack Kelly: Is there a problem?
Doctor: Just wait here.
Dr. Abraham Erskine: So, you want to go overseas. Kill some Nazis.
Jack Kelly: Excuse me?
Dr. Abraham Erskine: Dr. Abraham Erskine. I represent the Strategic Scientific Reserve.
Jack Kelly: Jack Kelly.
Jack Kelly: Where are you from?
Dr. Abraham Erskine: Queens. 73rd Street and Utopia Parkway. Before that, Germany. This troubles you?
Jack Kelly:No.
Dr. Abraham Erskine: Where are you from, Mr. Rogers? Mmm? Is it New Haven? Or Paramus? Five exams in five different cities.
Jack Kelly: That might not be the right file.
Dr. Abraham Erskine: No, it's not the exams I'm interested in. It's the five tries. But you didn't answer my question. Do you want to kill Nazis?
Jack Kelly: Is this a test?
Dr. Abraham Erskine: Yes.
Jack Kelly: I don't wanna kill anyone. I don't like bullies. I don't care where they're from.
Dr. Abraham Erskine: Well, there are already so many big men fighting this war. Maybe what we need now is the little guy, huh? I can offer you a chance.
Dr. Abraham Erskine: Only a chance.
Jack Kelly: I'll take it.
Dr. Abraham Erskine: Good. So where is the little guy from, actually?
Jack Kelly: Manhattan
Dr. Abraham Erskine: Congratulations, soldier.
