BEYONDER REALM
It was a silent place, there were many beings known as Beyonders, but they have longer lives, so they just passed their time by looking over the Marvel Multiverse.
Since Ben has closed the way between the Beyonder Realm and Marvel Multiverse, now their time has passed in boredom.
They were now focused on a single place, this was the same place, where Ben had sacrificed himself. They noticed the massive energy was gathering together. They thought Beyonder was coming back again, and they tried to stop it.
But they can't even go near 1 km of the massive energy. So, they just watched it, and didn't understand what was happening there.

Stark and Pepper Potts are now married and are living in a remote cabin with their daughter Morgan.

At the Avengers Facility, Romanoff now commands the team as they perform various assignments. Rhodes informs her of a recent cartel massacre carried out by Barton, expressing his concern over how far their former comrade had fallen.
Natasha started crying, hearing this.
"You know, I came to ask the time, but you seem pretty miserable already," Steve said, as he came there.
"You came to tease me?" She asked him, to which he replied, he had come to help her. And talking about all the positive things.
"Look friend, if you are going to talk about positive things. I'm about to hit you in the head with my eaten peanut butter sandwich," Natasha replied.
"Sorry, it has become a habit," Steve replied as he came and sits together with her, "Although I told everyone to forget about it, but we can't forget it," He nodded as they were remembering their friends.
Suddenly a notification comes, that someone was standing on their door, which Natasha accepted.
"Hello, anyone is at home, I am Scott Lang. We met a few years ago at the airport in Germany. I was the guy who became so big. I am Ant Man," Scott was standing on the door and shouting.
"Is it an old message?" Steve asked.
"No, he was standing in front of our gate," Natasha replied.
Scott Lang arrives inside and reveals to Romanoff and Rogers that he was stuck inside the Quantum Realm. And before he gets out with the help of Hope, Thanos comes and then a blink happens.
"I'm sorry, that must have been a very long five years," Natasha condolences him.
"Yeah, but that's the difference, that although five years had passed, I spent five hours in the realm," Scott replied.
He revealed, anything can happen in the Quantum Realm, and their time works in different ways.
He proposes that they could find a way to exploit the realm's time-bending nature to travel into the past and retrieve the Stones from different times.
But since the three have no knowledge of the handling with quantum physics, they sought out Stark, who was living a normal life with his family.
"I know, it sounds weird, but we need to try it," Scott said.
"Quantum fluctuations will destroy everything, it created a big mess. You will not be able to return back from it," Tony explained to them.
"I have come back," Scott answered.
"You didn't come back, you accidentally survived. It's a billion-to-one cosmic fluke. And you can't do the Time heist on this fluke," Tony mocked him.
They argue about it, but Tony declines to help them, as he believes it would mean putting his daughter Morgan in danger of being erased from existence.
"Well, he's scared," Natasha said as they were returning back from Tony's house.
"Every father is afraid," Steve agreed.
"Yeah, but, I mean, what are we gonna do without him? Are we going to cancel the Time heist?" Scott asked.
"No, we will do it. But, we just need a big brain!" Steve answered.
They go to find the Hulk, Scott was shocked to see Hulk, who has now after understanding the Hulk was not the disease but it was cured, he mixed the Hulk's body with Banner's brain.
Now he was fit and fine, they tried to talk to him about the Time heist and included him to work together.

Meanwhile, Stark later decides to spring into action after coming across an old photo of him and his late protégé Peter Parker.
He successfully develops a time-space GPS based on an inverted Möbius strip. Stark consults with Potts on his new discovery, who encourages him to do what's right for everyone else.

"Okay, here we go. Time Travel test number one. Scott, fire up the van," Banner ordered, and Scott did as the command, they were running time travel tests on Lang using his van, they checked everything was ready.
"Good, because even if a little mistake happens. Then the Tiny being will be lost in 1950," Banner warned.
"Excuse me?" Scott asked, to which Natasha answered, Banner was just joking.
"Sorry, it was a bad joke," Banner said while Scott goes in the front of the van. Natasha again confirmed with Bruce, that's was really a joke.
"I have no idea. We're talking about time travel here. Either it's all a joke or none of it is," Bruce replied to Natasha, then he turned towards Scott and thumbs up at him, "We're good! Wear your helmet."
The experiment does not turn out as expected, as Lang constantly shifts between different ages.
"Time Heist! It's successful," Banner said as he gave a successful sign, then he looked at Steve's sad face.
"What's happened? Come on friend, now distribute sweets among the poor!"
Afterwards, Stark arrives at the facility. He noticed Steve's sad face, "What's happened, why the long face? Did the pants get wet during the Time heist?"
"Small mistakes happen in big countries. You tell me why you came here?"
"Rightly said, people learn only from mistakes. Your guy didn't go through the time, but time goes through him. It is a very dangerous thing, maybe someone needs to warn you?" Tony said.
"You already warned me," Steve replied.
"Oh, did I stop you? Well, thank God I'm here. And I am a genius," Tony replied as he showed a device to him, "Take it, a fully functioning time-space GPS."
He gives it to Steve and also returns the Vibranium shield to him, signifying their reconciliation, but makes it clear he won't sacrifice his daughter to undo what Thanos did.
Rogers agrees.
The remaining Avengers begin to regroup. As Nebula returns to New York, Banner and Rocket recruit Thor, who has become an overweight drunkard traumatized with his perceived failure to stop Thanos.
Romanoff goes to Tokyo and finds Barton, who massacred a group of Yakuza as part of his vengeful crusade against criminals who survived the Snap.
Rocket and Stark build a time machine, while Barton volunteers to submit himself for a test run into the past.
Grabbing a baseball mitt from his homestead, he successfully carries it back to the present as evidence that their plan works.
BEYONDER REALM
Beyonders species were looking at the massive energy, which has now taken the shape of the humanoid. It was the face and the body of Ben Tennyson, but it was massive even bigger than the Living Tribunal.
"So it was not that the Beyonder was reborn, but the other guy was reborn," Kaizu, the deputy leader of Beyonders species, said.
"Yes, he now has both his powers and the Beyonder powers, but we still don't know who is in control of this unlimited powers," Prazu, the second deputy leader of the Beyonders species.
"But we have to wait till he is not fully reborn," Himanzu, the leader of Beyonders species, answered.
They were seeing that Ben's size was decreasing as the time passed.
