Near the stratosphere above Earth
The Avengers and their allies, except Tony, Knuckles and his team, who are handling the situation in Wakanda all board the Benatar and the Halberd. On board the Benatar, Carol and Rocket are piloting the ship as they set to head to the alien planet where Thanos is located.
Rocket: Okay, who here hasn't been to space?
Nat, Steve, and Rhodey raise their hands.
Rhodey: Why?
Carol chuckles at the moment.
Rocket: You better not throw up on my ship.
Elsewhere on the Halberd, Blade and Sword are piloting where they are behind the Benatar to find the alien planet where Thanos is.
Sonic: I really wish that Tails were here to pilot this thing. It's like Thanos is begging us to sneak to his planet and take him down.
Lincoln: Apparently Lisa would like to visit outer space one day.
Lori: Yeah, and Leni would make us space outfits if she was here.
Jet: I've been to space with Wave and Storm lately while struggling to regain the Arks of the Cosmos from that big robot known as ABIS.
Amy: All right, you guys! Let us prepare for the jump.
SpongeBob: Here we go! Last time I was in space with Sandy lately.
Leonardo: All hands on deck.
They all hung onto something.
Back on the Benatar.
Nebula: Approaching jump in 3... 2... 1!
Both ships jump forward into a wormhole, and we see Steve holding onto his seat for dear life. A close up of his eyes show them widening slightly at the exhilaration of this new experience.
Sonic & SpongeBob: Woohoo!
Michelangelo: This is amazing!
Big: Feels good!
Rocky: It sure is fun though!
They slow down, and both ships hover in orbit above Planet 0259-S.
SpongeBob: I really wish Patrick would enjoy this ride.
Carol flies out of the Benatar.
Carol: I'll head down for recon.
Kirby exits the Halberd on his Warp Star to investigate the planet.
Kirby: Let me investigate where he is now.
In the ship, Steve took out his compass with a picture of his love interest, Peggy Carter back in his time, which Nat noticed before Steve closed his compass.
Nat: This is gonna work, Steve.
Steve: I know it will. 'Cause I don't know what I'm going to do if it doesn't.
Carol and Kirby approach the ships.
Carol: No satellites, no ships, no armies, no ground defenses of any kind. It's just him.
Nebula: And that's enough.
Sonic: Let's do this!
Raphael: Finally. (cracks knuckles)
Thanos' Hut, outside
An injured Thanos is collecting some crops to prepare his stew. Thus still wearing the damaged Infinity Gauntlet after the Snap. Until then..
Kirby: (from a distance) Surprise!
Carol fires a photon blast at Thanos, who used the Infinity Gauntlet to protect himself from the blast before Kirby spits out a star at him. They attack him before Carol puts him in a headlock position. Bruce in a Mark XLIX Hulkbuster Armor holding his left arm with the gauntlet on it. Rhodey in his War Machine armor to hold his right arm. Seconds later, Thor busts in the hut to chop off his left arm with the Infinity Gauntlet, which Thanos screams in pain and agony. The Avengers came into the to confront the Mad Titan before noticing the gauntlet without the stones in it.
Sonic: The stones are gone!
Rocket: (shocked) Oh no!
Amy: What happened to them?
Steve: Where are they?
Carol: Answer the question!
Thanos: The universe required correction. After that, the stones served no purpose, beyond temptation.
Bruce: You murdered trillions! (He pushes The Mad Titan to the ground)
Silver: And my future is in ruins because of you.
Thanos: You should be grateful. (Gets punched by Banner)
Sonic: Grateful? You've destroyed everything!
Lola: And killed all our friends and family.
Lori: You killed my Boo-Boo Bear!
Raphael: And our sensei!
They eventually beat up Thanos until they are restrained by Leonardo, Jet, and Lincoln.
Lincoln: Easy, you guys! Let's just interrogate him about the stones' whereabouts.
SpongeBob: This is like searching for the secret recipe of the Krabby Patty.
Silver: No need to get fired up on attacking him. But let's get to the nitty gritty, shall we?
Nat: Where are the Stones?
Thanos: Gone. Reduced to atoms.
Amy & Blaze: Huh?!
Bruce: You used them two days ago!
Thanos: I used the stones to destroy the stones. It nearly killed me. But the work is done. It always will be. I am... inevitable.
Jet: (angrily) Inevitable?
Plankton: They must have went subatomic or something.
Rhodey: We have to tear this place apart, he has to be lying.
Nebula: My father is many things. A liar is not one of them.
Mikey, Don, Kirby, and Big all nod at each other.
Michelangelo: I guess she's right.
Donatello: From the looks of it Splinter might be gone from now on.
Big: And I will never see my Froggy again.
Thanos: (to Nebula) Ah, thank you, daughter. (Nebula looks down, a little uncomfortable.) Perhaps I treated you too harshly.
When the last two seconds hit, an enraged Thor chops off Thanos' head with Stormbreaker, which causes everyone to watch in horror for what Thor did.
Sonic: Whoa!
Rocket: Thor?
MermaidMan: The horror!
Silver: He couldn't even finish.
Rocket: What? What did you do?
Thor: I went for the head.
Jet: That's what he told you about.
Thor: I know.
Blaze: I guess it's never gonna be the same again.
It comes to this, the Avengers and their allies has come accept that Thanos destroyed the stones in the process to make sure the Snap does not get reversed. They lost all hope and morale. Suddenly, Nebula closed her father's eyelids out of respect. However, Lola runs out of the hut to vomit after seeing Thanos' dead body, which made Sonic, Plankton, and Lincoln flinch.
Sonic & Lincoln: (disgusted) Ew, gross.
Plankton: That's disgusting.
Lola: (feeling better) Sorry, you guys! I really miss Lana and her gross moments.
Lori: We literally know. But Thanos destroyed the stones.
MermaidMan: Let's go home and face facts.
SpongeBob: Mr. Stark guessed that Strange was right. There is definitely no other way.
Leonardo: It's time to head back.
The turtles, SpongeBob, Plankton, Sonic, Cheese, Big, Amy, Lincoln, Lori, Lola, Jet, and Yacker had no choice to accept the losses that Thanos caused to them and become emotional, Thor walked out of the hut in despair with no other choice to accept the fact that the Mad Titan's actions are indeed permanent. Now our heroes will have to live on, some without their friends and family, as the survivors of the universe.
