Goku, Scott, Steve, and Natasha went to meet Bruce Banner having breakfast at a restaurant. Bruce is now more Hulk like than before.

Bruce: Come on, I feel like I'm the only one eating. Try some of that. Have some eggs.

Scott stayed silent as he couldn't believe who he's looking at.

Scott: I'm so confused.

Goku: These are confusing time, buddy.

Bruce: What's more confusing is that I can barely recognize you, Goku. If it weren't for the tail, the build and your hair, I would've mistaken you as someone else.

Goku: Thanks, Bruce.

Bruce: Additionally, I'm glad you got over your depression. It's hard for us to see you like that.

Scott: Wait, you were depressed?

Goku: Yeah. Don't want to talk about it though. It just hunts my mind. Let's just say, I blamed myself for what happened 5 years ago, but thanks to my mom and my dad, I recovered.

Then, three kids go up to Bruce.

Girl: Excuse me, Mr. Hulk?

Bruce: Yes?

Girl: Can we take a photo of you?

Bruce: 100% little person. Come on, step up?

Bruce hands the phone to Scott, as one of the kids noticed Goku.

Boy: Hey, your Goku Rogers. Can you be in the photo, too?

Goku: Uh, sure.

Goku moves in and joins the pose.

Bruce: Say 'green'.

Others: Green!

Scott takes the photo.

Bruce: Did you get it?

Scott hands back the phone.

Scott: Don't you wanna grab one with me? I'm Ant-Man.

The kids seemed confused.

Scott: They're Hulk fans, they don't know Ant-Man.

Bruce: Wait, no, no, he feels bad. No, he wants you to... he wants to... You want to take a picture with him, right?

Scott: He's even saying no he doesn't. I get it. I don't want it either.

Bruce: *turns to the kids* He's gonna feel bad. Sorry They said they'd do it.

Scott: I don't want it anymore.

Bruce: No, no... you feel bad.

Scott: Just take the goddamn phone.

Goku gave him a small smack in the head.

Scott: What was that for?

Goku: Dude, there's kids around us.

As the kids say goodbye, Goku sat down as Bruce turns to everyone.

Bruce: Right. The Hulk time travel do-over? Guys, it's outside my area of expertise.

Nat: Well, you pulled this off. I remember a time when that seemed pretty impossible time, too.

Goku: Come on, Bruce. We can do this.

Bruce: I'm in.

*later*

The next day, at the Compound, Bruce was working on setting up the machine for testing. Goku volunteers and took Scott's place, while using clothes beam to create Scott's suit. As Bruce and Scott were making the preparations for the test, Steve and Natasha watvh, though worried for Goku.

Bruce: We're good! Get ready, Goku. We're gonna send you back a week, let you walk around for an hour, then bring you back in 10 seconds. Makes sense?

Goku: Perfectly not confusing.

Steve: Good luck, son. Be careful.

Goku: Don't worry, dad. I got this.

Bruce: On the count of three. 3... 2... 1!

Goku disappears into the Quantum Tunnel. Five seconds, Bruce press a button and someone came back, a kid.

Goku: That's odd. I'm a kid again.

Steve: He must be a year younger than before.

Bruce tries to fix the problem as he goes for another alternative. Then, Kid Goku gets sucked it, and returns more older than before.

Goku: Wow. I feel more older than before.

Bruce: You look more adult, but still the same.

Goku: Saiyans can stay the same up to 70, and I might not grow some facial hair.

Steve: Can you bring him back?

Bruce; I'm working on it.

After a moment, a baby appears.

Steve: It's a baby!

Bruce: I'm baby Goku!

Nat: He does look adorable as a baby.

Steve: Bring Goku Back.

Bruce: Scott, go to those controls and standby. Nat, When I say kill the power, kill the power.

Nat walks over the lever as Scott is on standby.

Bruce: And...kill it!

Natasha killed the power, Peter and Bruce pressed the buttons as Goku returns as a teenager.

Goku: That was fun! Can I do that again sometime?

Bruce: Time Travel!

Scott: Yeah, somewhat?

Bruce: What? I see this as an absolute win!

*later*

Goku: Well that didn't work. But that was funny, from kid, to adult, to baby is something I never experienced.

Steve: At least I know what you'll look like when you're older. Now what are we gonna do?

They then hear noise, a car was coming in at high speed. The car passed by Goku and Steve. then reverses to them. The window rolls down and they see Tony.

Tony: Why the long faces? Let me guess, you became a test monkey and turned to a baby.

Goku: What gave us away, Sherlock? What are you doing here?

Tony steps out of the car and walks towards the back.

Tony: That's the EPR paradox. Instead of pushing you through time, you might've wound up pushing time through Goku. It's tricky. Dangerous.

Goku: But fun.

Tony: Somebody shoulda cautioned you against it.

Steve: You did.

Tony: Oh, did I? Thank God I'm here. Regardless, I fixed it. *shows them a device* A fully functioning Time-Space GPS. I just want peace. *makes peace sign* Turns out, resentment is corrosive, and I hate it.

Steve: Me, too.

Goku: Me, three.

Tony: We got a shot at getting these stones, but I gotta tell you my priorities: Bring back what we lost? I hope, yes. Keep what I got? I have to, at all costs. And... maybe not die trying will be nice.

Steve: Sounds like a deal.

Steve reached out his hand to shake. Tony took it and shakes.

Goku: Then we're all good.

Tony: Yeah, we're all good. Oh, one more thing.

Tony reached the back of his trunk and pulls out Captain America's shield. He give it back to Steve who hesitates.

Steve: Tony, I-

Tony: Why? I made it for you. Plus, honestly I have to get it out of the garage before Morgan takes it sledding.

Steve took it and wields the shield again.

Steve: Thank you, Tony.

Tony: Will you keep that a little quiet? Didn't bring one for the whole team. *looks at Goku* By the way, kid. After that incident in Germany, I modified extensively to your suit. Now, It's the matching colors of your Gi.

Goku: Sweet. I still have my weapons here. We got the gang back together.

Tony: And speaking of the team, we are getting the whole team, yeah?

Steve: We're working on that right now.

*later*

Later, Rocket and Nebula arrived with Rhodey as the get to see Goku now a teenager.

Rocket: Holy Shit! I now about Saiyans, but I didn't expect kids to grow this big!

Nebula: You saiyans are unpredictable. But I will admit you're quite the looker.

Goku: *chuckles* Thanks, Nebula.

Rhodey: I don't I'll get use to this. I was use to you being small, but this, you're a giant.

Then, Thor arrived with Stormbreaker with him.

Thor: It's good to see everyone back together.

He turns to see Goku, and was surprised to see him.

Thor: By the All Fathers, Goku is that you?!

Goku: Yep. It's me, Thor.

Thor drops his weapon and quickly hugs Goku.

Thor: I barely recognized you! You've grown into a fine young man!

Goku: Thanks, buddy.

After the the reunion, Natasha managed to bring back Clint, who had a career as the Vigilante Ronin. Everyone had a discussing about the situation, as they agreed to begin the mission. First, they locate each infinity stone and they separate into three groups. They have one shot at this.

Goku goes to his room as he sets up his suit. It starts to materialize around him like Tony's in nano tech as he looks at memory, admiring his armor.

He then sees a picture of him, Wanda and Pietro there and grabs it. He stares at it for a way, making a silent promise. He then looks back at the mirror, until in a quick flash, his reflection had his hair got longer and spiker, golden yellow eyes, and when he opened his mouth after getting startled, he has fangs on his teeth.

After being spooked by the jumpscare, he calms down and set the picture back where it was and leaves his wrong with his shield and sword. He and the The Avengers walks towards the Quantum Time machine, wearing their Quantum suits. They arrived and joined their fists.

Steve: Five years ago, we lost. All of us. We lost friends... We lost family... We lost a part of ourselves. Today, we have a chance to take it all back. You know your teams, you know your missions. Get the stones, get them back. One round trip each. No mistakes. No do-overs. Most of us are going somewhere we know. But it doesn't mean we should know what to expect. Be careful. Look out for each other. This is the fight of our lives. And we're gonna win. Whatever it takes. Good luck.

Rocket: He's pretty good at that.

Goku: He always is.

They all go to the platform, getting ready. Scott, Bruce, Tony, Steve, Goku, Natasha, Clint, Rhodes, Nebula, Rocket, and Thor are prepared for time travel.

Nat: See you in a minute.

Goku: You too, mom.

The Quantum Tunnel activates, everyone dons their helmets, they then jump through the Quantum Tunnel and travels through time.
