Captain Marvel, Superman and the Tamers

On board the Benatar, Tony Stark a.k.a Iron Man and Nebula are playing paper football when Nebula catches the paper football.

"Wrra!" Nebula said frustrated before putting her hands in a fighting stance while looking at Tony.

"You don't need to do that. Because uh...you're just holding position." Tony said and Nebula flicks a paper football towards Tony. "Oh yeah, that was close."

Then Nebula once again flicks a paper football towards Tony.

"That's a goal. Now we're one apiece." Tony said.

"I would like to try again." Nebula said before flicking the paper football towards Tony.

"We tied up. Feel the tension? It's fun." Tony said before poorly flicking a paper football towards Nebula.

"That was terrible. Now you have a chance to win."

Nebula flicks the paper football towards Tony.

"And you've won. Congratulations." Tony said before reaching his hand out to shake Nebula's hand.

"Fair game. Good sport."

Nebula shakes Tony's hand.

"Have fun?" He asked.

"It was fun." She admitted.

The scene changes to see Iron Man's busted helmet. Tony Stark's hand reaches forward to turn on the helmet. We pan out to see that he's sitting on the floor of a gloomy Benatar. The weight of the recent events of Infinity War evident in Tony's posture. He taps the helmet with a sigh.

"This thing on?" He asks while the helmet scans Tony who leans against the wall while taking deep breaths. He looks skinnier and weak with malnutrition. "Hey, Miss Potts...Pep. If you find this recording, don't post it on social media. It's gonna be a real tear-jerker. I don't know if you're ever going to see these. I don't even know if you're...if you're still...Oh god, I hope so. Today is day 21, uh 22." Now Tony was standing at a window staring out into space, waiting for his impending doom to arrive.

"You know, if it wasn't for the existential terror of staring into a void of space, I'd say I'm feeling better today. The infection's run it's course, thanks to the blue meanie back there." Tony keeps saying while Nebula was sitting in the back of the Benatar. "You'd love her. Very practical. Only a tiny bit sadistic. Some fuel cells were cracked during battle, but we figured out a way to reverse the ion charge to buy ourselves about 48 hours of time."

Later Tony and Nebula were working on the fuel cells of the Benatar.

"But now it's dead in the water. We're 1000 light years from the nearest 7-11. Oxygen will run out tomorrow. And that'll be it. And Pep, I...I know I said no more surprises, but I was really hoping to pull off one last one. But it looks like...well you know what it looks like. Don't feel bad about this. I mean, if you grovel for a couple of weeks and then move on with enormous guilt. I should probably lie down. Please know that...when I drift off, I will think about you. Because it's always you." Tony ended.

With that, Tony turns the helmet off. He rubs his thumb over the left eye and then leans down, to what would be his last sleep. Nebula walks over to him and carries him to Drax's seat, then places him there. She walks away dejected. A vast bluish nebula illuminates the space surrounding them. Cut to a shot of Tony's face, which for the first time shows age and weakness. There is a light on his face, which grows brighter and brighter until he's forced to open his eyes. The camera pans around to the light source, which is slowly revealed to be Carol Danvers.

"It's been a while Stark." When the light faded, a man in a red and blue costume with a red S in the middle floated to the right of Carol Danvers.
