Once Spidey and his side of the crew were at the decepticon's location (which was on what was left of cybertron), they exited the spacecraft and began to look for Megatron.

"Okay, once we find Megatron, we will destroy the gauntlet and destroy him. Then we go home and party like it's 1969," said Spider-Man. Suddenly, they were greeted by the appearance of Megatron him-freaking-self. "Megatron! Where is Applejack's geode?!"

"So, the cowgirl has a name. As for the geode, it belongs to me," said Megatron, as he showed off the infinity gauntlet. "If you want to get the geode back, you'll have to pry it from my cold dead hands."

"Challenge accepted," said Spider-Man. He and his colleagues began to attack Megatron. Considering he was very tall, he was able to overtake them. "Shit! He's too strong!"

"Don't worry, I got this," said Iron Man. He then began to use his energy blasters to damage Megatron… except it only dented his head.

"All that for a drop of oil," said Megatron.

"Impossible," said Iron Man. Suddenly, Megatron grabbed Spider-Man and took his geode, which he used to teleport to planet earth. "Spidey, are you okay?"

"Well, my geode just got taken away, and I've been put into a chokehold, but other than that I'm okay," said Spider-Man, rhetorically.

"We gotta get back home before it's too late," said Apple Bloom. They all got onto the spaceship and started flying back home.

Meanwhile, back on earth, the Canterlot Avengers and the Wakanda warriors were getting ready to take on the Decepticons, with some autobot reinforcements.

"FOR EARTH!" yelled Button Mash, who was leading the charge. As the Wakanda army fought for their planet, Megatron grabbed the geodes off of the humane five and placed them on the gauntlet.

"Yes! At long last, the stones are mine for the taking!" said Megatron. Suddenly, the spaceship with Spider-Man's part of the crew arrived.

"MEGATRON!" yelled Spider-Man, who was full of rage. "Hand over the geodes or face the fury of the mighty Canterlot Avengers."

"I'm afraid you're too late Spider-Man, for I have all of them. And there's nothing you can do to stop me!" said Megatron.

"Think again!" said Optimus Prime, as he tried to take the gauntlet off of Megatron's hand. "You will never destroy another planet like you did with Cybertron.

Suddenly, Applejack used her mighty ax to stab Megatron right in the spark. "Any last words you piece of crap?" asked Applejack. She pushed the ax further into Megatron's chest, not knowing that the gauntlet was still in his hand.

"Yes…" said Megatron, weakly, while leaking oil. "You should have gone for the head." And all of a sudden…

0/SNAP/0

Megatron had snapped his fingers, and he then used the gauntlet to make a daring escape. "NOOOO! We were so close!" said Spider-Man, in a fit of rage. He managed to calm himself down, but then his spider senses were tingling so he knew something was wrong. "Oh no."

"Um guys," said Fluttershy, as she started to disintegrate into nothing but dust, causing the others to gasp.

"AJ, help," said Rainbow Dash while disintegrating, as her girlfriend held her hand until it was nothing but thin air. Applejack began to cry as she quickly realized that she was next.

"Hector, promise me that you'll take care of Apple Bloom while I'm gone," said Applejack, facing Spider-Man, who was also crying.

"I promise, I'll make you proud," said Spider-Man, as he unveiled his face to Applejack one last time.

"You already have," said Applejack, as she disintegrated into nothing but dust, causing Spider-Man and Spider-Girl to tear up.

All over the galaxy, people were beginning to fade into dust as their friends and family mourned their loss.

"So, what are we going to do now?" asked Sly. Spider-Man unmasked himself.

"We enter the endgame now," said Hector.

Post credit scene:

Derpy was waiting for the Canterlot Avengers, when they finally arrived.

"We came as soon as we could, what was the big emergency?" said Spider-Man.

"If I fade away, activate this beeper," said Derpy, as she handed a modified beeper to Spider-Man. Suddenly Derpy turned into nothing but dust.

"What do you think it does?" asked Spider-girl, as Spider-Man activated the modified beeper. Suddenly, a large bang was heard outside of the Avengers headquarters. "What the hell was that?"

They all went outside and found a girl wearing a suit similar to Captain Marvel. "Where's Derpy?" asked the freshman age girl, who looked surprisingly familiar.

"Sunset Shimmer?" asked Spider-Man.

That's right, Sunset Shimmer's human counterpart is Captain Marvel. Also in case you were wondering, the portal to Equestria was destroyed so Sunset Shimmer will be stuck there for a while. Anyways, after this it's time for the endgame. Until then, that's all folks… for now.
