New York City, 2012
Tony is seen flying around Stark Tower in the Mark 85 while Knuckles scales on the wall of the Chrysler Building. He scans the interior of the tower, and sees the original Avengers apprehending Loki, the backside of the iconic shot of Hawkeye pointing the bow at Loki's face while the Avengers surround him.
Tony: Better hustle, guys. Things look like they're just about wrapped up here.
Steve: (on comlink) Got it. I'm approaching the elevator now.
Sonic: (also on comlink) Kirby and I will be on lookout in case something like this happens.
Knuckles: Now let's get in the tower to look at the scene of the century.
Both Knuckles and Tony flew inside Stark Tower on the top floor where the 2012 Avengers are confronting 2012 Loki, but they hide in plain sight to avoid detection.
2012 Loki: If it's all the same to you, I'll have that drink now.
2012 Tony: All right, get him on his feet. We can all stand around posing up a storm later. By the way, feel free to clean up.
Knuckles: (looks amazed) Wow, you look good with that suit, Mr. Stark. It's kinda cool, though.
Tony: (to Knuckles) Thanks, Knuckles! (scoffs to look at Steve's suit) Mr. Rogers, I almost forgot that that suit did nothing for your ass.
Sonic: (in disbelief) Ugh, Stark! What do you come up with that?
Steve: No one asked you to look, Tony.
Tony: [whispers] It's ridiculous
Ant-Man: I think you look great, Cap. As far as I'm concerned, that's America's ass. (Does a patriotic salute.)
Knuckles: (also salutes) I agree with you, Scott.
Kirby: Guys, stop looking at Rogers' backside like perverts and focus on the nitty-gritty.
Knuckles: Oh, right!
2012 Natasha: Who gets the, uh, magic wand?
2012 Tony: S.T.R.I.K.E. team's coming to secure it.
Suddenly, Knuckles, Tony and Scott hide from S.H.I.E.L.D.'s S.T.R.I.K.E. team lead by Jasper Sitwell and Brock Rumlow, who are the agents of HYDRA, but they would not be exposed until 2014. As they entered the building and come to take the scepter.
2012 Sitwell: We can take that off your hands.
2012 Natasha: By all means. Careful with that thing.
2012 Clint: Unless you want your mind erased. And not in a fun way.
2012 Sitwell: We promise to be careful.
Ant-Man: Who are these guys?
Tony: They are S.H.I.E.L.D.. Well, actually HYDRA, but we didn't know that yet.
Knuckles: You mean these guys are HYDRA after they attempt to perform Project Insight to target all of us?
Ant-Man: Seriously? You didn't? I mean, they look like bad guys.
Tony: You're small, but you're talking loud.
Knuckles: Just make sure you're tiny and quiet, from the look of it.
2012 Steve: On my way down to coordinate search and rescue.
2012 Loki: (transforms and imitates 2012 Steve) On my way down to coordinate search and rescue! (Transforms back to his normal form) I mean, honestly, how do you keep your food down?
2012 Thor: [Slapping on a device on Loki's mouth to make him quiet] Shut up.
Tony: All right, you're up, little buddy. [Looking at the briefcase with the Tesseract] There's our stone.
Ant-Man: [Lying down on Tony's shoulder] Alright. Flick me.
Tony flicks Scott onto his 2012 self. Moments later, Tony gets out of the tower by activating his Arc Reactor to transform into his Mark 85 armor to locate the scepter. However, all of the 2012 versions of Tony, Thor, Loki and some S.H.I.E.L.D. agents get in an elevator. 2012 Hulk makes to follow, but finds the elevator full.
2012 Hulk: Move.
2012 Tony: Hey!
2012 Thor: Whoa, whoa, whoa!
2012 Tony: Hey, hey. Buddy. What do you think? Maximum occupancy has been reached.
2012 Thor: Take the stairs.
2012 Tony: Yeah. [Hulk draws his fist back right as the elevator door closes] Stop, stop.
[He follows through with the punch, making a dent in the wall right where the door was.]
2012 Hulk: (looks upset) Take the stairs! Hate the stairs!
Outside the tower, Iron Man flies around to locate the scepter, which is in the elevator with the S.T.R.I.K.E. team.
Tony: All right, Cap. I got our scepter in the elevator just passing the 80th floor.
Steve: On it. Head to the lobby.
Tony: Alright. I'll see you there.
Meanwhile, Knuckles regroups with Sonic and Kirby, who is in his Robobot armor, are watching from the side of the Chrysler Building, seeing Steve in the elevator with the S.T.R.I.K.E. team.
Sonic: Well that seems kinda impressive.
Knuckles: Come to think of it, Loki started imitating Cap before Thor placed something on his mouth in order to be taken to Asgard to pay for his crimes.
Kirby: That sounds awkward.
Knuckles: Quite frankly, he is the God of Mischief since he started all of this mayhem by sending the aliens to attack the largest city in the world.
Sonic: (notices something) Uh, guys! I think you should come look at this.
Knuckles and Kirby join Sonic to witness the tension in the elevator Steve was in which was similar that he fought Rumlow and his team back at the Triskelion in 2014.
Knuckles: It's like things are heating up eventually.
Kirby: Not necessarily, Knuckles! (points to the men in the elevator about the status of the scepter)
Sonic: I think he might be in some kind of trouble or maybe he could actually mess up the timeline.
Kirby: I have a feeling that you're right, Sonic! He would mess things up after he gets the scepter.
Knuckles: (noticing Steve whispering into 2012 Sitwell's ear) Please tell me he didn't say "Hail HYDRA."?!
Sonic: In that case. He's got the scepter. Let's go!
Just as soon as they leave their position, Knuckles glides to rejoin Tony, who is searching for the Tesseract, while Sonic and Kirby enter Stark Tower to find Steve, who has the scepter.
Inside the tower, the stairs.
2012 Hulk: (still upset) So many stairs!
Meanwhile, in the lobby.
The 2012 Avengers start to make their way out of the building. Tony in disguise as an operative of S.H.I.E.L.D. spotting his past self.
Tony: Thumbelina, do you copy? I've got eyes on the prize. It is go time.
Ant-Man: Bombs away. (sliding down to 2012 Tony's shirt before smelling something) Is that Axe body spray?
Tony: Yeah, I had a can just for emergencies. Relax. Can we focus, please?
Ant-Man: I'm going inside you. Now. (he shrinks to go inside of 2012 Tony's Arc Reactor)
Knuckles arrives to notice Tony disguised as a S.H.I.E.L.D. operative in order to obtain the Tesseract. Moments later, the 2012 Avengers and S.H.I.E.L.D. operatives are approached by HYDRA operatives disguised as S.H.I.E.L.D. agents in attempt to get the cube.
HYDRA Leader: May I ask you where you're going?
2012 Thor: Bit of lunch and then Asgard. I'm sorry, you are...?
2012 Tony: Alexander Pierce. He's the man, one of the folks behind Nick Fury.
2012 Pierce: My friends call me Mr. Secretary. I'm gonna have to ask you to turn that prisoner over to me.
2012 Thor: Loki will be answering to Odin himself.
2012 Pierce: No, he's gonna answer to us. Odin can have what's left. And I'm gonna need that case. That's been S.H.I.E.L.D. property for over 70 years.
HYDRA Agent: Hand over the case, Stark.
Tony: [To Scott through radio as he inhales sharply] All right, move it, Stuart Little. Things are getting dicey up here. Let's go.
Knuckles: Better step it up a notch, Scott!
2012 Tony: I'm not gonna argue who's got the higher authority here, all right?
Ant-Man: You promise me you won't die?
Tony: You're only giving me a mild cardiac dysrhythmia.
Ant-Man: That doesn't sound mild.
Knuckles: The clock's ticking, hurry it up!
2012 Pierce: I need the case.
Both Tony and Knuckles witness the situation starting to heat up really quickly.
Tony: Do it, Lang! Window's closing. Pull my pin!
Knuckles: Come on!
Ant-Man: Here goes!
Just as he pulls the pin of 2012 Tony's Arc Reactor, which cause past Tony to suffer a cardiac arrest drops the case. The guys are concerned for past Tony.
2012 Pierce: Stark?
2012 Thor: Stark?
Past Tony falls down to the floor.
Operative: He's convulsing. Give him air!
2012 Pierce: Medic!
Tony: Medic! Give these guys some help.
2012 Thor: Speak to me. Stark, is it your chest machine?
Ant-Man kicks the case, Loki sees it moving until Tony grabs the case just in time.
Knuckles: Well that did the trick. Okay, let's go!
Tony: Good job. Meet me in the alley. I'm gonna grab a quick slice.
Suddenly, 2012 Hulk pushes Tony to the ground before the case starts to open and the Tesseract slides to Loki's left foot.
2012 Hulk: NO STAIRS!
Everyone runs from Hulk's rampage, Knuckles witnesses 2012 Loki grabbing the Tesseract in order to escape from S.H.I.E.L.D. and the 2012 Avengers.
Knuckles: No! Loki took the Tesseract and got away.
Operative: Come on, Stark, stay with us!
2012 Thor: I'm going to try something, okay? I have no idea if it's gonna work.
2012 Thor uses the Mjølnir as the defibrillator on 2012 Tony.
2012 Thor: YES!
2012 Tony: That worked a treat. That was so crazy!
2012 Thor: I had no idea if that was gonna work.
2012 Tony: The case?
2012 Thor: The case is, uh... Where's the case? (noticing his brother is gone) Where's Loki? Loki!
Elsewhere, Knuckles joins both Tony and Scott.
Ant-Man: That wasn't supposed to happen, was it?
Tony: Oh, we blew it.
Knuckles: And Loki just stole the Tesseract which has the Space Stone in it.
2012 Thor: Loki!?
Elsewhere in the tower on a walkway several floors up. Steve is having trouble on his communicator, trying to contact Tony and Scott on the status of the Tesseract.
Cap: Tony, what's going on? Tell me you found that cube. [He looks up and groans.] Oh, you gotta be shitting me.
[In front of him, Steve sees his 2012 self looking back]
2012 Captain America: I have eyes on Loki. 14th floor.
Cap: [Puts the case down] I'm not Loki. And I don't wanna hurt you.
[2012 Steve engages and the two Captain Americas begin to duel.]
2012 Captain America: I can do this all day.
Cap: [Standing up] Yeah, I know. I know.
Both Caps throw their shields at one another which clang away as they brawl, inadvertently kicking away the case containing the scepter which falls down a few levels. 2012 Steve gets the upper hand on Future Steve's as they both fall down to the same level as the scepter. Future Steve's locket of Peggy falls out, 2012 Captain America notices it.
2012 Captain America: Where did you get this?
[2012 Cap has his future self in a chokehold]
Cap: Bucky is alive!
2012 Captain America: What?
Cap takes the chance to sucker punch his counterpart, grab the scepter and knock his past self out. Sonic and Kirby arrive to meet Cap.
Sonic: Hey, Cap, are you all right?
Kirby: We see you've fought your past self to get by.
Cap: Yeah, guys! I was hoping that didn't happen. (looks at his past self) That is America's ass.
Sonic: (disgusted) Ugh, Cap, seriously?
Kirby: (also disgusted) You just looked at your own butt.
Moments later, the trio left with the scepter, which contains the Mind Stone.
Meanwhile at the TCRI Building, Leo and Don manage to gain entry to the building while the scientists are working.
Donatello: (using his goggles to scan the building) Okay, Leo, I got eyes on the prize, on the top floor.
Leonardo: Let's get in the ventilation shaft to find the supplies for the new gauntlet to put the stones in.
Donatello: Here we go!
Just as they get in the vent area that leads to the top floor of the building, and then the duo started crawling into the vents to find the file room that contains the supplies.
Leonardo: Uh, Donnie!
Donatello: What?! (looks at the same room where Bebop and Rocksteady transformed) This is actually the location where Baxter Stockman transformed the criminals Bebop and Rocksteady into a rhinoceros and warthog with the mutagen.
Leonardo: That sounds complicated and intense. Well we better focus on getting the supplies first.
Donatello: All let's do it!
As the turtles of blue and purple head down to the labs where the supplies are being kept until they notice something unfamiliar.
Leonardo: Hey, Don, look!
Donatello: Looks like we found it!
They enter the room, which was unlike the same one where April's father was killed by Eric Sacks, who was working for the Shredder.
Donatello: Come on, let's get out of here before they find us.
They both leave the place to rejoin the others.
As I did not even add the Theft of the Time Stone scene where Bruce pleading The Ancient One to give him the Time Stone in order to undo Thanos' Snap from the present day. Just as a coincidence, an unfamiliar room was similar where April's father was killed by Eric Sacks by the fire, which resulted his daughter to get the turtles and Splinter to safety. Unfortunately, Loki escaped with the Tesseract to avoid imprisonment on Asgard, which would lead to the upcoming Loki series.
