New Avengers Facility ruins, outside
Outside the ruined compound, the Sanctuary II looms above and it beams a 2014 version of Thanos fully armored to the ground. 2014 Nebula walks towards him.
2014 Thanos: Daughter.
2014 Nebula: Yes, Father.
2014 Thanos: So, this is the future. Well done.
As she takes off the orange plate on her head and throws it away.
2014 Nebula: Thank you, Father. They suspected nothing.
2014 Thanos plants his double-bladed sword on the ground, takes off his helmet and places on top of the sword's edge.
2014 Thanos: The arrogant never do. (He then sits down) Go. Find the stones. Bring them to me.
2014 Nebula: What will you do?
2014 Thanos: Wait.
2014 Nebula proceeds to go find the stones and the camera pans over the Sanctuary II and we see 2014 Gamora watching. As she heads over to where Nebula is being held prisoner.
2014 Gamora: Tell me something. In the future, what happens to you and me?
Nebula: I tried to kill you. Several times. But eventually, we become friends. We become sisters.
As 2014 Gamora responds to the information, she extends her hand to Nebula.
2014 Gamora: Come on. We can stop him.
Nebula takes her hand to help.
Inside the ruins of the facility
Tony walking towards Steve, who's unconscious on the ground.
Tony: Come on, buddy. Wake up. That's my man. (He has Cap's shield in hand) You lose this again, I'm keeping it.
Seconds later, Sonic was seen waking up and sees Kirby, who woke up as well.
Sonic: Wait, what's going on? Kirby, are you all right?
Kirby: Yeah, Sonic! I'm fine!
Shadow gets out of the rubble before walking up to the four.
Steve: What happened?
Tony: You mess with time. It tends to mess back. You'll see.
Shadow: This is the reason why Silver explained about his future caused by Thanos.
Sonic: Tony, what do you mean by that?
Tony: As I told Steve about messing with the past.
And then SpongeBob and Caliburn came into view.
SpongeBob: Looks like we have company.
Caliburn: Anyhow, where are the others?
Sonic: They're somewhere under the rubble.
As Tony helps Steve up on his feet. They walk up to join Thor, Knuckles, and Leonardo, who have been observing 2014 Thanos from a distance.
Caliburn: Look.
Sonic: (surprised) What? Why's he back?
SpongeBob: He's suppose to be dead.
Leonardo: He must have came from 2014 to undo our work.
Tony: What's he been doing?
Thor: Absolutely nothing.
Steve: Where are the stones?
Tony: Somewhere under all this. All I know is he doesn't have 'em.
Steve: So we keep it that way.
Thor: You know it's a trap, right?
Tony: Yeah. And I don't much care.
Sonic: Well I've been through many traps before. And I don't care by this point.
Kirby: Same here, Sonic.
Thor: Good. Just as long we are all in agreement.
Thunder cracks as Thor's eyes glow and stretches out both hands to summon both Stormbreaker and Mjolnir. His casual clothes transform into his armor and cape, with his beard getting some braid treatment.
Sonic & Knuckles: (awestruck) Whoa!
Thor: Let's kill him properly this time.
Knuckles: Here we go!
As the heroes began to walk over to confront the Mad Titan face to face.
2014 Thanos: You could not live with your own failure. And where did that bring you? Back to me. I thought by eliminating half of life, the other half would thrive. But you've shown me that's impossible. And as long as there are those that remember what was, there will always be those that are unable to accept what can be. They will resist.
Tony: (sternly) Yep, we're all kinds of stubborn.
Kirby: And maybe because overpopulation doesn't necessarily exist.
2014 Thanos: I'm thankful. Because now, I know what I must do. (he stands up) I will shred this universe down to its last atom. (he puts on his helmet) And then, with the stones you've collected for me, create a new one. Teeming with life, but knows not what it has lost but only what it has been given. (Thor lights himself up.) A grateful universe.
Steve: Born out of blood.
Shadow: Not to mention dust. But you have no desire for revenge. You only crave destruction and genocide. Your only lust is to obtain the stones until there is nothing left of reality itself.
2014 Thanos: They'll never know it. Because you won't be alive to tell them.
Sonic: We'll see about that.
Knuckles: Bring it on!
Big Arms by Tee Lopes & Jun Senoue plays
The fighting starts as Sonic, Steve, Thor, Tony, Knuckles, Kirby, SpongeBob, Leonardo, and Shadow go straight at 2014 Thanos engaging in a heated battle against him, with the Mad Titan holding them off.
Inside, lower level
Hulk and Don are under all of the mess trying to hold up the structure. Amy, Rhodey, Rouge, and Rocket are breathing for their lives.

Rouge: You too. Come on, Rocket!
Rocket: OK, Rouge!
Amy: Let's go!
Elsewhere, Scott is still small while Plankton and Mikey are still keeping Rhodey's new armor away from the water in order to save Bruce, Rouge, Don, Rhodey, and Rocket.
Ant-Man: Hang on! We're coming!
Mikey: Almost there!
Plankton: Just hold on!
In the sewers
Hawkeye and Jet are still protecting the Nano Gauntlet while outrunning the Outriders. Clint plants several explosive arrows behind him and Jet, blowing up the sewers, and escape before the Outriders overwhelm them. Clint lays and Jet sits to catch their breath before seeing 2014 Nebula.
Clint: Oh, hey. I know you.
Jet: Wait a second.
Clint gives her the gauntlet. then she puts her hand on her earpiece.
2014 Nebula: Father.
Clint and Jet gasped and find out that she's from 2014.
2014 Nebula: I have the stones.
Clint & Jet: What?!
Clint tries to get up but 2014 Nebula steps her foot down on him an points her gun at him.
2014 Gamora: Stop.
She aims a blaster at 2014 Nebula, who backs away from Clint and Jet.
2014 Nebula: You're betraying us?
With her hands up, Nebula joins 2014 Gamora. 2014 Nebula points her gun at her future self.
Nebula: You don't have to do this.
2014 Nebula: I am this.
2014 Gamora: No, you're not.
Nebula: You've seen what we become.
2014 Gamora: Nebula, listen to her.
Nebula: You can change.
2014 Nebula: He won't let me.
She points a gun at 2014 Gamora.
2014 Gamora: NO!
Present Nebula shoots her past self and she dies. Silver, Blaze, and Raph arrive.
Jet: Whoa!
Raph: I can't believe she did that.
Silver: For the meantime, she killed her past self. Shouldn't she disappear?
Clint: I'm not sure yet! But she could be repair once we're done anyway.
Blaze: All we have to do is find the others.
Hawkeye picks up the Infinity Gauntlet and continues to protect it.
Outside
Back to the battlefield, the heroes are fighting 2014 Thanos.
Iron Man: (after landing on the ground) Okay, Thor. Hit me.
Thor bangs his hammer and ax together combined with his lightning. Tony's suit sucks up the energy and he shoots it out using his hands and his body. Thanos twirls his blade really fast to divert the energy. Thor grabs Stormbreaker and uses it to bat Mjolnir to hit 2014 Thanos. However, he uses Tony as a shield resulting in damage to his system.
F.R.I.D.A.Y: Boss, wake up!
Steve and Sonic attempt to attack Thanos but is easily shielded away by the Mad Titan. Sonic disarms the Mad Titan with Caliburn and punches 2014 Thanos with his Spike Shields before releasing a kinetic energy pulse to push the madman back before getting punched in the face, sent flying in the process. Thor's attack on 2014 Thanos is blocked by his sword. Thor is beaten and choked by 2014 Thanos, as he punches him. Shadow uses his Chaos Control before firing the Chaos Spear at 2014 Thanos. Mjolnir is flicked away as 2014 Thanos relentlessly beats up Thor, throwing him into rubble and socking him before throwing him over rubble and socking him again. Leonardo, Shadow, and Knuckles attempt to save the Asgardian by attacking 2014 Thanos before being mauled. Kirby in his Robobot Armor with the Rock Copy Ability attack the Mad Titan with his fists become taking damage. SpongeBob appears as Invincibubble, blowing bubbles from his bubble wand on his head, hitting the madman's eyes by irritating them until he gains the upper hand by throwing the muscular sponge into a pile of rubble. Thor tries to grab Stormbreaker but 2014 Thanos grabs it and uses it against Thor as he tries to defend himself. Mjolnir starts to float off the ground while 2014 Thanos is digging it into Thor, when suddenly Mjolnir flies into 2014 Thanos, zooms past, stops, and flies back into the hand of Captain America, who is worthy of the mighty hammer.
Supporting Me ...for Biolizard plays
Knuckles: (awestruck) Oh, my!
Thor: I knew it! (gets kicked by the Mad Titan)
He proceeds to battle Steve dual wielding both his shield and Mjolnir. Steve proceeds to charge at Thanos swinging Mjolnir and hitting Thanos in the face knocking him down. Steve throws his shield and 2014 Thanos deflects, Steve throws Mjolnir to his shield creating a shockwave and knocking 2014 Thanos off his feet. Steve goes on the offensive on 2014 Thanos, throwing his shield first at the Mad Titan and quickly hitting it back at him again with Mjolnir. He lines his arm back up and underarms a channel of lightning on 2014 Thanos.
However, 2014 Thanos eventually gets the upper hand, he removes his helmet, stabs Steve on the leg and knocks Mjolnir out of his hand. 2014 Thanos proceed to destroy Steve's shield with his double-bladed sword, which brought shock to Sonic.
Sonic: (shocked) Oh, no!
2014 Thanos breaks the shield four more times before throwing Steve across the battlefield. However, 2014 Thanos was once again hit by Mjolnir until it winds up in the hands of Sonic the Hedgehog. Kirby gets back up and sees the Robobot Armor, now damaged before grabbing the sacred sword.
Sonic: All right! Let's do this!
The blue hedgehog attacks the Mad Titan with Mjolnir by overwhelming him with a blow to the face before passing it to Kirby, who uses both hammer and sword at the same time by firing lightning at him. Sonic spin dashes before rolling into the Mad Titan. Kirby in his Rock Copy Ability began to give 2014 Thanos an uppercut.
Kirby: I stared into the eyes of Galeem. And now Galeem is staring back.
2014 Thanos: I heard a lot about you and Captain Marvel. Ronan was a mere fool trying to kill you both.
Momentarily, he gets the upper hand by throwing the puffball to the ground, next to Steve. Leo and 2014 Thanos spar with their swords. Until then, the madman kicks the him towards the rubble. SpongeBob and Sonic continue to fight 2014 Thanos by passing Mjolnir by shooting lightning and bubbles before the Mad Titan disarms the duo of the hammer with his double-bladed sword. Sonic shields himself from the attack before being pushed back, SpongeBob gets punched as well, next to the leaders. As Steve, Sonic, SpongeBob, Kirby, and Leo struggle to get back up as 2014 Thanos talk calmly to them.
2014 Thanos: In all my years of conquest, violence, slaughter, it was never personal. But I'll tell you now... what I'm about to do to your stubborn, annoying little planet... I'm gonna enjoy it. Very, very much.
And that's the end of the chapter. Well, Sonic, Steve, SpongeBob, and Kirby are now worthy to lift Mjolnir. This is a major callback to Avengers: Age of Ultron, which Steve barely lifted the hammer during a lifting contest. Until then, Vision lifts the hammer because Odin's enchantment did not recognize him. Most importantly, time for the big reunion. And the Battle of Earth begins.
