New York, 2012
With the Battle of New York going underway, at the sides of the buildings, the invading Chitauri troops snarling and shrieking after their large Leviathan has been destroyed and the iconic circle take around our six Original Avengers assembling. However, unknown to them, at a nearby alleyway, the present Avengers from 2023; Scott, Steve, Bruce, Tony, Sonic, Kirby, Leonardo, Donatello, and Knuckles suddenly arrived, having them safely traveled from the Quantum Realm and successfully traveled back in time to 2012.
Steve: All right, we all have our assignments. Two Stones uptown, one Stone, down. Stay low. Keep an eye on the clock.
Leo: On it, Cap.
Suddenly, everyone watch as 2012 Hulk smashing a Chitauri soldier through some wreckage. Bruce puts his hand on his face, embarrassed. Knuckles seems amused.
Sonic (sarcastically) Geez, you still learn how to smash stuff, Banner!
Knuckles: Heh, I would do better than that.
Steve: Maybe smash a few things along the way.
Bruce: I think it's gratuitous, but whatever.
[Present Bruce pretends to smash things in a sarcastic way. He tears his shirt off, and walks over to a car. He lightly punches the car, making a small dent, all the while making growling noises. He picks up a motorbike and throws it at a wall, wincing as it hits the wall.]
Don: I bet Raph could do some of the smashing. (to Sonic) Sonic, I made them for you!
The turtle in purple gives the hedgehog some upgraded vibranium shields, which he puts them on.
Sonic: Sweet! Thanks, Donnie!
Meanwhile, at the Roof of the Sanctum Sanctorum a bald woman fights off the Chitauri soldiers with her magic. Bruce, Leo, and Don try to enter through the door before noticing her.
?: I'd be careful going that way. We just had the floors waxed.
Don: You must be the Ancient One?
The Ancient One: Of course I am!
Leo: Master Splinter knew all about you.
The Ancient One: (to Leo) He did? (to Bruce) And what do you want?
Bruce: Yeah, I'm looking for Doctor Strange.
The Ancient One: You're about... five years too early. Stephen Strange is currently performing surgery about twenty blocks that way. What do you want from him?
Leo: 20 blocks?
Don: That's where TCRI Building is. Thanks for the tip.
Leo: Let's go, Donnie!
They leave Bruce to ask the Ancient One about the Time Stone. While jumping from building to building, the turtles of blue and purple comment about the technology in TCRI Building.
Don: Uh, Leo! Shouldn't we get Dr. Banner to join us to come with us to TCRI Building?
Leo: No, let him ask the Ancient One for the green stone in her necklace. I think he'll join us later.
Don: (activates his scanning goggles to where the TCRI Building's location.) There it is. Up ahead. Now we have to go underground to avoid to alien attack from the sky.
Leo: Good idea.
Asgard, 2013
Somewhere in the Asgardian Palace is the dungeon, where Loki is locked away, sitting in his cell, throwing a ball. Unknown to the God of Mischief, Rocket, Jet, Mikey, Silver and Thor creep by, past the cell. They stop at a pillar a few meters away room of where Jane Foster is. However, Jane is being escorted by a maiden to one of the chambers to rest.
Asgardian Maid: For you, Lady Jane.
Jane: Um, so you have anything with pants?
Asgairdian Maid: (confused) Pants?
Jane: Never mind. These will be fine. Thank you.
Asgardian Maid: Yes, milady.
Unbeknownst to the women, the five continue to hide behind the columns.
Thor: Oh, there's Jane.
Rocket: All right. Here's the deal, Tubby: You're gonna charm her and I'm gonna poke her with this thing, (he holds up a device) and extract the Reality Stone and get gone, lickety-split.
Silver: Yeah, hopefully it will be nice and easy.
Thor: I'll be right back, okay?
Mikey: Thor, where are you going?
Thor: The wine cellar is just down there. My father used to have this huge barrel of Aakonian ale. I'll see if the scullery has a couple of to-go cups.
Rocket: Hey! Hey! Aren't you drunk enough already?
Jet: Hurry up, you won't survive for much longer.
A door opens, the five Avengers slightly emerge from their hiding spots. Thor sees his mother. Moments later, Thor becomes emotional as he saw his mother Frigga as he remembers that she is to die on this day just hours before the upcoming Sacking of Asgard.
Rocket: Who's the fancy broad?
Thor: That's my mother.
Mikey: She looks like an angel.
Silver: That woman, Frigga is a royal lady.
Thor: She dies today.
Rocket: Oh, that is today?
Jet: I am so sorry, Thor.
Mikey: Not a good sign. (turns to Thor, who is freaking out) You okay, Thor?
Thor: I can't do this. I can't do this. I shouldn't be here. I shouldn't have was a bad idea.
Rocket: Come here. [Standing in front of him]
Thor: No, no, no. I think I'm having...I'm having a panic attack. I shouldn't be here...this is...this is a bad-
Rocket: Come here. Right here.
[Rocket slaps Thor in the face.]
Rocket: You think you're the only one who lost people? What do you think we're doing here? I lost the only family I ever had. Quill, Groot, Drax, the chick with the antenna, all gone. Now, I get you miss your Mom. But she's gone. Really gone. And there are plenty of people who are only kinda gone. But you can help them. So is it too much to ask that you brush the crumbs outta your beard, make schmoopy talk to Pretty Pants, and when she's not looking, suck out the Infinity Stone and help me get my family back.
Jet: And I want Wave and Storm back.
Silver: And I also want to see Blaze again.
Thor: Okay.
Rocket: Are you crying?
Thor: No.
Silver: Uh, Thor?
Thor: Yes. I feel like I'm losing it.
Jet: Show some courage, Thor.
Rocket: Get it together! You can do this. You can do this. All right?
Thor: Yes, I can.
Rocket: Good.
Thor: I can do this. I can do it, I can't do this.
He sneaks away from the group.
Silver: Now let's get down to business, shall we?
Rocket: Alright, Heartbreaker. She's alone. This is our shot.
Jet: Yep, our only shot.
Mikey: And we- (turns around to see Thor missing) Uh, guys.
Rocket: (Turns back to where Thor was moments ago)Thor? Thor!
Silver: Looks like we're gonna do this ourselves.
Jet: I bet there are some treasures in this glorious palace where all the loot is.
Mikey: Jet, can we focus on the task at hand?
He does so.
Rocket: All right, let's go!
Morag, 2014
Nebula, Raph, and Rhodey are currently bringing out the Benatar space pod before Shadow, Rouge, Black Widow and Hawkeye could use the M-ship.
Rhodey: Alright. Bring it down, Blue. Right on that line. That's it. Down, down.
Suddenly, Nat kicks an Orloni creature.
Rouge: Geez, these alien rats give me the creeps.
Hawkeye: Hey, can we hurry it up?
Black Widow: Guys, chop-chop. Come on. We're on a clock.
Shadow: It's about time.
Nebula walks out of the ship, apparently having directed it to its next destination.
Rhodey: All that, is really helpful. [Hugging Natasha] Take care, okay?
Black Widow: Yeah.
Rhodey: Get that stone and come back. No messing around.
Raph: Definitely. We can't lose either of you guys.
Shadow: We won't, Raph.
Hawkeye: [To Rhodey] Hey.
Rhodey: We got this.
Hawkeye: Let's get it done.
Rhodey: Yes, sir.
Raph: We will get the job as soon as we can, Clint.
Hawkeye: I'll see you back.
Rhodey: You guys watch each other's six.
[Clint and Nat look back and just smile.]
Hawkeye: Yeah.
Raph: Be careful, you guys.
[They walk back into the ship, and the hatch closes. The ship takes off and speeds out of the atmosphere of Morag.]
Nebula: The coordinates for Vormir are laid in. All they have to do is not fall out.
[In the Benatar, Shadow, Rouge, Clint and Nat are sitting at the front of the ship. The ship takes a jump through space and speeds up tremendously. The heroes look at each other.]
Hawkeye: It's a long way from Budapest.
Natasha and Rouge both laugh at the moment.
Rouge: Come to think of it, sure sounds like a maiden voyage.
Shadow: No doubt about it, this is way beyond glory.
Black Widow: Tell me about it.
Back on Morag, where Raphael, Rhodey and Nebula are still standing there.
Rhodey: Okay, so, uh... We just wait around for this Quill guy to show up and then he leads us to the Power Stone, is that it?
Nebula: [Looking around] Let's take cover. We're not the only ones in 2014 looking for the stones.
Rhodey: Wait a minute, what are you talking about right now? Who else is looking for these stones?
Raph: Besides the Star-Lord.
Nebula: My father, my sister... and me.
Raph: (shocked) What?!
Rhodey: And you? Where are you right now?
Bikini Bottom, 2015
Somewhere in the outskirts of Bikini Bottom, SpongeBob, Lincoln, who has a bubble so he could breathe, and Plankton are finding their way towards the island before Burger Beard arrives and steals the book.
Lincoln: So this is Bikini Bottom.
SpongeBob: Yes, Lincoln! But it's an absolute peaceful beautiful day just hours before the famine occurs.
Plankton: Which we became the hunted, until we got away from the rioting mob.
Lincoln: So they started tearing apart the town?
They both nod before noticing the Krusty Krab just an hour before The Food Fight for the Krabby Patty Secret Formula.
Plankton: I think we can see the Krusty Krab from here before the events took place.
SpongeBob: I was knowing that you were innocent that Burger Beard took the formula from our hands, which it disappeared and came to him.
Plankton: So then, let's get to the surface right away.
Lincoln: Here we go!
They make their greatest adventure to the surface.
The Time Heist did as the Avengers planned they would get the Infinity Stones from a few locations. However, the magic book also occurs which SpongeBob and Plankton discussed about the Krabby Patty Famine in Bikini Bottom caused by Burger Beard.
