The Sanctuary II continues to unleash a hailstorm of missiles on the Avengers and their allies, which included White Wolf, Amy, Big, Froggy, Master Splinter, Casey, Espio, Vector, Korg, Iron-Man, War Machine, Hulk, Susie, Squidward, Mr. Krabs, Raphael, the Babylon Rogues, Cream, Cheese and Groot. Rocket appears and protects Groot from the mayhem, and Cream did the same to Cheese.
Cream: It's going to be the end for all of us!
Cheese: Chao! Chao!
Suddenly, the ship's cannons stopped firing.
Wave: Wait, they stopped firing at us!
Squidward: But they're shooting at something else.
Moments later, the ship's cannons are aiming at the sky and started firing, which confuses everybody.
Rouge: What in the world?
Classic Knuckles: What's going on?
Falcon: What the hell is this?
Meta Knight: That must be her!
Iron-Man: F.R.I.D.A.Y., what are they firing at?
F.R.I.D.A.Y.: Something just entered the upper atmosphere.
A bright light of thundering energy comes surging down from the sky and flies through the ship, and it results in an explosion. The light turns out to be Captain Marvel.
Rocket: Oh, yeah!
Cream: Hooray!
Cheese: CHAO!
Cap and Super Sonic along with Tails and Kirby watch as Captain Marvel proceeds to crash through Sanctuary II again.
Tails: Who's that?
Super Sonic: A new friend.
Kirby: (cheering) MY FRIEND HAS FINALLY ARRIVED!
She emerged from the ship and looks at it from above as it crashes into the river as a bewildered Thanos looks on in disbelief.
Captain America: Danvers, we need an assist here.
Super Sonic: And like right about now.
As Ant-Man finally started activating the Quantum Tunnel. Captain Marvel landing next to Patrick, Charmy, and Spider-Man, who is on the ground, holding the Nano Gauntlet nervously.
Spider-Man: Hi, I'm Peter Parker.
Charmy: I'm Charmy.
Patrick: And I'm Patrick.
Captain Marvel: Hey, Peter Parker, Charmy, Patrick. You boys got something for me?
As the three get up before explaining.
Patrick: Here's that strange glove with some weird-looking rocks that big mean-looking purple guy is after.
Charmy: (points to something) We've got incoming!
The four noticed a large number of Outriders, Chitauri, Chitauri Gorillas and Sakaraans approaching them, being lead by Corvus Glaive.
Spider-Man: (hands her the gauntlet) I don't know how you're gonna get it through all that.
Patrick: There has to be some other way get by.
Scarlet Witch: (arrives next to the four) Don't worry.
Okoye: (also appears) She's got help.
Amy: (joins the women) Why don't you boys just take a little break for a while?
Rouge: (joins too) Let's not make it too risky.
Suddenly, Cream, Rescue, Mantis, Shuri, Burning Blaze, Zan Partizanne, Francisca, Flamberge, Susie, Wave, Wasp, 2014 Gamora, Nebula, Classic Amy, Sandy, Vividria, and Valkyrie gather around to give Captain Marvel her support.
Sandy: As Mrs. Puff and Karen would say "GAL PALS"!
Thanos' army charge while the ladies help Captain Marvel go through the monsters. Scarlet Witch throws a hex ball at the Outriders. Mantis messes with the Chitauri Gorilla's mind before Vividria uses her Art Attack on it. 2014 Gamora shot and slashed right through the Chitauri Gorilla. Both Classic and Modern Amy use their Piko Piko Hammers to whack the Outriders. Cream uses her Chao Attack on the Sakaraans before using her Wispon. Rouge performs Screw Kick on the Chitauri. Burning Blaze shoots fire at the Leviathan with Scarlet Witch holding it. Susie shoots the monsters with her before deploying her Business Suit.

The Mage Sisters use their elemental powers on the Outriders. And Sandy using her karate skills against the Sakaraans. Scarlet Witch uses her telekinesis to hold off a Leviathan as Valkyrie uses her sword to slice through another.
Meanwhile, Spider-Man, Patrick and Charmy look on in awe.
Spider-Man, Charmy, & Patrick: (awestruck) Wow, look at them go!
Charmy: What an ultimate lady team up!
Patrick: They're are good butt kickers like Mermaid Man and Barnacle Boy from their past.
Spider-Man: (spots something) Uh, guys! I think you wanna see this!
They turn to Web Slinger's direction as a second large number of invaders approaching the opposite direction where the ladies are, led by Proxima Midnight and Ebony Maw.
Charmy: It looks like we've got a number on our hands. (holds out a Wispon)
Patrick: We're ready!
Espio: (turns visible in front of them) On guard!
Super Sonic: (lands next to Espio) Here we come! You all ready?
Knuckles and Tails appear.
Tails: Of course!
Knuckles: We're with you until the end!

Ant-Man: Just came to join the battle.
Jet: Why aren't you at the van?
Super Silver: I formed a shield around it so Thanos couldn't get to it.
Marx: Let's save the chatter for. We got a battle to win.
"What I'm Made Of" starts playing.
Vector: All right. Let's get 'em, boys!
Charmy: Time to get serious!
Team Sonic rush to the center of the battle and fight the Outriders and Chitauri before performing their old Team Blast move, Sonic Overdrive.
Super Sonic: Blast away!
He uses his Light Speed Attack on the invaders. Knuckles uses his Drill Claw Attack on the Sakaraans. Tails uses Tail Swipe before throwing the Dummy Ring Bombs on the Chitauri. Kirby dismounts from the Robobot Armor before inhaling the aliens and spitting them out as stars until he gets back in the armor to fight the monsters. Iron-Man fired a few grenades at the aliens, obliterating them. Cap and Thor combine their lightning powers, aiming both Mjolnir and Stormbreaker at the aliens. M'Baku began bashing one alien on the head before taking down another. Wong uses his Sling Ring Portal to slice a Leviathan, which it came from the opposite direction. Giant-Man holds a Leviathan in place until War Machine fire missiles at it. Super Lincoln slices the monsters with Caliburn. SpongeBob blows bubbles at the aliens. Hawkeye fires multiple arrows at the aliens while Hulk throws them in the air before smashing them. Spider-Man shoots his webs at several Outriders and Sakaraans until he uses the legs to kill them.
Vector: Give it all you got, boys!
Espio & Charmy: Right!
They perform Team Blast, Chaotix Recital which resulted the aliens' ears ringing and it allows the Chaotix to attack. However, Charmy starts stinging one before using a Wispon on another until he approaches Sonic, who use his shields while the bee shoots out a laser on them, deflecting it and killing the aliens in the process. Super Shadow uses Chaos Control to stop time before going inside a Leviathan to use Chaos Blast to make it explode. Omega, Rocket and Bucky fire their guns at the Outriders before Bucky lifts Rocket and began fire all around them just like they did in Wakanda. Jet uses his Bashosens to stir some wind before Storm threw and punched them. Star-Lord blasts the alien with his quad blaster before taking down another. Drax stabs a few with his knives. Groot stretches his arms to kill three Outriders. Kraglin uses Yondu's old Yakku Arrow by whistling it to take out a Necrocraft, some Chitauri and Outriders. Black Panther uses his claws to slash the aliens before unleashing a kinetic energy pulse. Ray and Mighty take down the aliens by punching and throwing them in the air. Captain America lets Super Sonic summon Mjolnir before the hedgehog blasted lightning at the group of Chitauri Gorillas. Sonic passes the hammer to SpongeBob, who combines lightning and bubbles to shock the Chitauri. The sponge throws the mighty hammer to Lincoln, who uses the sword and hammer to decimate the monsters.

SpongeBob: Score one for the boys back home.
Back on the other side of the battlefield, Captain Marvel then starts flying towards the van with the Nano Gauntlet, flying past enemies and going through enemy blockades that are in her way with ease. Thanos, seeing this, starts running to Captain Marvel, but is stopped by Rescue, Shuri, Cream, and Wasp, who blast him backwards with their lasers. Thanos, after seeing Captain Marvel fly past him, throws his double-bladed sword at the van, destroying it and the quantum realm tunnel, throwing Captain Marvel backwards and losing her grip on the gauntlet, which falls to the ground. Doctor Strange steadies the water after the explosion. In the final standoff for the Nano Gauntlet, Iron-Man moves one of Thanos' armies aside and sees the Gauntlet. He runs to get it, but sees Thanos, who Iron-Man tackles. Thanos smacks the genius away, knocking him out. Then Thor arrives with Stormbreaker and Mjolnir in an attempt to pin Thanos' arm down, with assistance from Captain America, SpongeBob, Leo, Raph, and Super Sonic. However, Thanos overpowers them and knocks them all out. Momentarily, Kirby scans Mjolnir before transforming into the God of Thunder's form. Kirby begins to attack the Mad Titan with the hammer. Eventually, Thanos gains the upper hand to disarm the armored puffball before throwing him to the ground. After picking up the glove, Captain Marvel arrives, punching away at Thanos while he is holding the Nano Gauntlet. She keeps punching him, but Thanos grabs her by the arm and flings her away. Thanos puts on the gauntlet, gamma radiation from the stones eating at him as he tries to snap, but the former Kree Soldier arises again, and stops his fingers from snapping, opening up his hand similar to what Captain America did in Wakanda. Thanos headbutts her, but it does nothing. Just as she is gaining the upper hand by rising up and forcing Thanos onto his knees, Thanos pulls the Power Stone out of the Gauntlet and uses it in his free hand to take out Captain Marvel. Kirby looks on.
Kirby: (gasps) Carol, no!
As he starts to attack Thanos by punching him in the face before wrestling him to the ground. Quite frankly, the Mad Titan gains the upper hand by punching the armored puffball with the Power Stone in his hand. Upon, seeing this, Iron-Man looks at Doctor Strange, who simply raises one finger, reminding him that the one win over Thanos he foresaw is now at risk, which was revealed that he sacrificed the Time Stone five years ago to save his life and now know what has to be done. Or is it? Stark nods. Thanos puts the Power Stone back into the Nano Gauntlet, yelling from the gamma radiation coursing through him, until Iron-Man makes one last attack on Thanos, grappling on the gauntlet before Thanos punches him away.
Thanos: I am inevitable.
Thanos snaps his fingers, but nothing happens except a metallic "clink." He sees the Infinity Stones are missing. Tony has the stones on his own gauntlet, the gamma radiation coursing through him, to Thanos' shock.
Iron-Man: And I... am... Iron Man.
After taking a deep breath, he snaps his fingers and the Infinity Stones activate in a blinding flash of energy. Rocket, Cream, and Charmy are firing at a Leviathan.
Charmy: It's coming down!
Cream: This is it!
As the three duck for cover, the Leviathan suddenly turns into dust before it could crush them. Cheese looks confused at them moment.
Cheese: Chao, chao!
With Iron-Man's snap starting to take effect, all of Thanos' army starts crumbling to ash. Black Panther and Star-Lord look around in surprise with Squidward, who is back to normal started joining them.
Squidward: Wow, is it over already?
Black Panther: Indeed, Squidward, we won.
Elsewhere, Espio, Vector, Scarlet Witch, King Dedede look at the monsters disappear around them.
Espio: The battle is finally over.
Scarlet Witch: It sure is, Espio!
The rest of the Avengers, including Captain America, SpongeBob, Lincoln, Kirby, and Sonic look on in exhaustion, starting to witness Thanos' forces, including the Black Order, Chitauri, Chitauri Gorillas, Leviathans, Sakaraans, and the Outriders and even the dropships and the remains of the Sanctuary II started to disappear. Thanos, in horror, looks around and sees his entire army turn to dust. He looks at the five, who all just stare at him.
SpongeBob: Yeah, we did it!
Kirby: Phew, that was pretty tough!
Sonic: Too bad it's all over...
Lincoln & Sonic: ...FOR YOU!
Just as Thanos looks around and starts to realize that his fate had already been sealed this time. He then starts to speak his final words.
Thanos: I am forever... I am... invincible...
He then begins to sit down on the ground and watched the sunset solemnly as his allies disappeared before his eyes, accepting his defeat with dignity until he fades away into nothingness.
Moments later, Tony, after snapping his fingers, the power of the stones' raw energy has left his entire right side fatally injured. He stumbles for a bit before his body collapses besides a pile of debris. Rhodey soon flies in and goes up to Tony to see his long time colleague and friend fading away. He bows his head, knowing the damage was done. Spider-Man rushes in and sees his mentor collapsed on the ground.
Spider-Man: Mr. Stark? [He runs up to his fallen mentor. Tears start to form in his eyes] Hey! Mr. Stark? Can you hear me? It's Peter. Hey. We won, Mr. Stark. We won, Mr. Stark. We won. You did it, sir. You did it. (breaks into tears) I'm sorry. Tony.
Peter is gently led aside to grieve. Pepper sits in front of her fading husband.
Pepper: Hey.
[Tony is barely able to move his head, but manages to look Pepper in the eyes]
Tony: (dying) Hey, Pep. (looks at Peter as well) Kid...
[Pepper places her hand on Tony's Arc Reactor and Tony rests his hand on hers. Pepper takes a good look at Tony's fatal injuries.]
Pepper: F.R.I.D.A.Y.?
F.R.I.D.A.Y.: Life functions critical.
[Tony smiles with tears in his eyes.]
Pepper: Tony. Look at me. [She makes sure Tony gets a long look at her smiling face] We're gonna be okay. You can rest now.
With that acknowledgement, Tony's Arc Reactor flickers off for good, leaving Pepper, Peter, and Rhodey, with Captain America, Thor, Sonic, Shadow, Knuckles, Kirby, SpongeBob, Plankton, Lincoln, Caliburn, Leo, and Raph looking on.
Knuckles: (in sadness) Oh, no! Stark, why'd you have to do this?
SpongeBob: (also sad) He gave his life to defeat Thanos.
Seconds later, Pepper can no longer contain her grief and starts crying on his shoulder after kissing him, along with Peter and Rhodey, who also cry. Tony Stark, the Iron Man, Earth's Best Defender, has died. Upon seeing this Hawkeye was the first to kneel before Iron-Man out of respect, followed by Black Panther, Patrick, Meta Knight, and Captain Marvel. Team Sonic, Team Dark, SpongeBob, Plankton, Lincoln, Kirby, the turtles, and Splinter also took a knee to honor the fallen hero. Star-Lord, Nebula, Valkyrie, Team Chaotix, Silver, Blaze, and Sandy join in. Ant-Man, Captain America, Thor, Team Rose, and Doctor Strange, who knew what had to be done before taking a knee. Team Babylon, King Dedede, and Bandana Dee also kneel, although Wave feels bad for Strange, who knew the outcome. M'Baku, Kraglin, Miek, Korg, and Casey all join in. Eventually, that moment reminds Kraglin about Yondu's sacrifice after defeating Ego. Susie, the Mage Sisters, Old Man Jenkins, and Chef Kawasaki also joined. However, 2014 Gamora looks on before leaving. Dr. Eggman of Classic and Modern also leave the scene, along with their robots, including the classic and modern versions of Metal Sonic, Orbot, and Cubot. Afterwards, the rest of the Avengers, Guardians of the Galaxy, Mobians, Bikini Bottomites, and the Wisps. Although Mantis was the last to kneel after looking at the scene. All the heroes, minus Peter, Rhodey, and Pepper honor the fallen Iron-Man.
That is the end of the chapter. One of the most saddest scene of the movie, which Iron-Man sacrificed himself to erase Thanos out of existence. However, this was a familiar scene where Blaze sacrificed herself to seal Iblis, which Silver was sad about. It was a very cool scene where Captain Marvel shows up to turn the tide of the battle until the A-Force scene came along. However, the other side of the battlefield where the guys fought the aliens, which was a scene from J. Tom's Kingdom Hearts: Endgame. I added some quotes and old team moves from Sonic Heroes. The song "What I'm Made Of" by Crush 40 was added in the last part of the battle before Tony snaps his fingers. Eventually, after Thanos meets his demise, he copied one of Mephiles' quotes. Man, I feel bad for Spider-Man, who lost his mentor, whom Morgan wanted to meet after he came back into reality.
