Back in the hideout; Samus was holding the lead container before opening it up, revealing the original Smash Ball and set it on a resting place.
"There, Smash Ball in position." said Samus.
Yoshi placed the Timer on a resting place.
"Yoshi." said Yoshi.
Sonic was placing the Chaos Emeralds on resting places as well.
"Chaos Emeralds as well." said Sonic.
"Good." said Samus.
"Prepare to undo the damage." said Fox.
The group started pushing buttons and pulling levers.
Sonic turned to Rayman.
"Hey, just out of curiosity, what did you tell Robin to do as a favor?" said Sonic.
At the New York Sanctum; Robin knocked on the door and it opened up, revealing an angry Doctor Strange who wasn't frozen in time with magic markings over his hands.
"WHO IS IT!?" yelled Strange.
He looked at Robin and became confused as his markings disappeared.
"There's a great threat that'll be coming, and I was sent here to get help in gathering a ton of allies." said Robin.
Back on Smash Island; Gwen picked up two unplugged extension cords before plugging them into each other.
She then smiled.
"All plugged in." said Gwen.
"Got it. It's possibly going to get ugly." said Meta Knight.
Incineroar pushed a button on a wall, causing some windows to close up.
Pikachu and Kirby each pulled out some keys before putting them into key holes and turning them.
A glass case opened up, exposing a red button.
Mario looked at the button.
"Let's a go." said Mario.
He pressed the button and a ton of power up sounds were heard followed by some sparking out.
Everyone stared on in shock.
"What if this doesn't work?" said Rayman.
"It will, I guarantee it." said Samus.
The machine stopped working and powered down.
The group became confused.
"Did it work?" said Sonic.
A vibrating sound was heard and Sonic pulled out his phone to see a text from Duncan saying 'Dude, do you know what time it is? I seem to have blacked out.'
Sonic started laughing and crying.
"It worked, it worked perfectly." said Sonic.
Everyone cheered.
"Finally, now to just-"Samus said before a ton of explosions happened all over the base, knocking everyone in different directions.
Outside the base; Xen was sitting in a room watching as tons of airships were firing lots of missiles at the base, destroying it bit by bit.
Xen chuckled.
"Yes, that's right, show those heroes that I mean business." said Xen.
He saw Mario, Samus, Kirby, and Fox running out from the ruins of the hideout and smirked.
"Come on out to your demise." said Xen.
The four veteran smashers continued running into the open when Xen appeared in front of the four.
The heroes stopped in their tracks and glared at Xen.
"Bolo." said Kirby (So you're behind all this.)
Xen looked at everyone.
"Does anyone even know what this puff ball's saying?" said Xen.
"You ain't going to be around much longer to see us being the victors." said Samus.
Xen chuckled.
"We'll see." said Xen.
He fired some lasers from his eyes at the heroes who ran off.
At the ruins; Sonic who had his leg trapped under some rubble was groaning in pain and trying to lift the pillar up.
"HELP, SOMEONE HELP!" yelled Sonic.
He heard some groaning and turned to see Pikachu under a pillar with his tail sticking out.
"Pikachu." said Sonic.
"It hurts so bad." said Pikachu.
"Don't worry, help is on the way." said Sonic.
At another part of the ruins; some crumbling sounds were heard and Incineroar who was underneath some stone lifted the stone up before tossing it away.
Gwen who was with Incineroar as well groaned.
"What hit us?" said Gwen.
They heard some more screaming and Incineroar lifted up another section, revealing Meta Knight and Rayman's head.
"Ray, Meta Knight." said Gwen.
Meta Knight stood up.
"We've been ambushed." said Meta Knight.
"Got to find the others." said Rayman.
Gwen nodded.
"Good call." said Gwen.
At another part of the ruins; a chunk of ceiling was destroyed and Mega Man, Donkey Kong, and Cloud emerged from it.
"Sheesh, that Xen guy really means business." said Donkey Kong.
"Hopefully the others are alright." said Mega Man.
"Maybe, better regroup with them." said Cloud.
But then a ton of Xen's Gigatronics and Tronics appeared.
Donkey Kong chuckled while clenching his fists.
"Oh I'm gonna enjoy this." He said.
The three heroes ran to the bots and started attacking each and everyone of them.
With Rayman's body; it grabbed the lead container before managing to stick the original Smash Ball into it as Gwen's group appeared.
Incineroar placed Rayman's head on top of the body parts as he grabbed the timer and Chaos Emeralds.
"Got the ball, now to worry about everyone." said Rayman.
With Sonic; he was still trying to push the pillar off his leg when a Tronic appeared and held it's blade at Sonic's neck.
The hedgehog groaned.
"Marvelous." Sonic said sarcastically.
But then Meta Knight appeared and started clashing his sword with the bot's sword.
The others appeared as Incineroar lifted the pillar up and Sonic stood up.
"You okay?" said Gwen.
"Yeah, I'm fine, nothing I can't walk off." said Sonic.
Incineroar set the pillar down before lifting the pillar with Pikachu under it as the mouse jumped on Sonic's head.
"Is the ball secured?" said Pikachu, "We can't let this evil guy get his hands on it."
Rayman nodded.
"Got it sealed." said Rayman.
"Good, now lets show this guy what we stand for." said Sonic.
The group ran off as Meta Knight destroyed the Tronic and followed.
Back outside the ruins; Mario, Samus, Fox, and Kirby continued fighting Xen.
Xen held up a boulder.
"Eat this." said Xen.
He tossed the boulder at the heroes, but Kirby inhaled it before swallowing the boulder and becoming Stone Kirby.
Xen groaned.
"Shit." said Xen.
Kirby made a stone hand appear before punching Xen far away.
Fox and Samus started firing beams at Xen.
Xen is mad.
"You ain't going to stop me." said Xen.
He stomped on the ground, creating a shock wave that knocked Fox, Samus, and Kirby off the ground.
Mario ran to Xen with his hands burning before punching Xen across the face.
"GO MARIO!" shouted Sonic.
But Xen punched Mario across the face, knocking him out.
"Nope, he failed." Rayman.
Sonic stepped forward.
"I'll keep this guy occupied for a while, regroup with the others." said Sonic.
The others became shocked.
"But Sonic." said Gwen.
"Just do it." said Sonic.
Gwen stared at Sonic before she, Meta Knight, Incineroar, and Rayman running off with the others in their hands.
"So you're the great Sonic the Hedgehog huh?" said Xen.
"What's it to you anyways, you tried to commit mass genocide." said Sonic.
"Just to ensure that there aren't to much heroes." said Xen.
Sonic scoffed.
"As if, you'll make things worse that way." said Sonic.
"I've heard you're good with a sword. Let's find out." Xen said before pulling out a double bladed sword.
Sonic made his Excalibur appear before going Excalibur Sonic.
"You'll be surprised." said Sonic.
The two ran towards each other before clashing swords with each other.
"You're good, but I'm a master." said Xen.
He kicked Sonic in the chest, sending him crashing into a boulder, but also letting go of his sword.
Sonic groaned as Xen ran to him.
The hedgehog held a hand out and his Excalibur flew towards him, only for Xen to grab the sword and lift it with ease, shocking Sonic.
"No, it's not possible." said Sonic.
"Don't tell me what's possible and not possible." said Xen.
He lunged the sword to Sonic who grabbed the blade to keep it from going through him.
Xen tried to push the sword into Sonic's chest.
"Give up the fight, there are to many heroes as it is." said Xen.
Sonic growled.
"There's never enough heroes." said Sonic, "Just to many villains."
Xen growled only to be punched across the face by Incineroar, sending him flying and letting go of the sword.
"INCINEROAR!" yelled Incineroar(No one harms my friend.)
Sonic chuckled.
"So you came to my help." said Sonic.
Incineroar lifted Sonic up as his sword and armor disappeared.
Xen growled in anger before pulling out a remote and pushing a button on it, making all his bots appear as everyone, including Yoshi and Mr. Game and Watch appeared.
The hedgehog started panting from exhaustion as he looked at the vast army of Xen.
"Oh boy, we won't be able to stop all these guys easily." said Sonic.
"Hey Sonic." Meek's voice said from his watch communicator.
Sonic became confused.
"Meek?" said Sonic.
"Are you there Sonic?" Meek's voice said.
Sonic pushed a button on his watch communicator.
"Yeah." said Sonic.
A portal opened up behind him.
"Behind you." Meek's voice said.
Sonic turned to the portal and saw Shawn, Jasmine, and Sky emerging from it before the three stopped in their tracks.
The four friends stared at each other before nodding.
The others noticed everything.
"Seems like the odds are in our favor." said Rayman, "And in the style of Avengers Endgame no doubt."
Then Meek in his armor flew from the portal before landing on the ground as his helmet disappeared before another portal opened up, this time Rock in his armor, Luna as the Purple Parasite, Sam with Tekko-Kagis, Jessica Cruz in her Lantern outfit, and Miss Martian emerged from the portal.
Several other portals opened up and every Toon Manor resident emerged from each of them, including the entire Justice League, the Avengers, the Supernoobs and their mentors, Bumblebee and Silo Prime's teams of Autobots in their vehicle forms before going robot mode, every Smash Brother and Sister, every Assist Trophy, every Pokemon in the Poke balls in every Smash Bros game emerged from each portal.
Then Fire Emblem Robin and Doctor Strange emerged from one portal.
"Is that everyone?" said Fire Emblem Robin.
Strange turned to the tactician in annoyance.
"What you wanted more?" said Strange.
He shook his head in annoyance.
Rayman looked at everything and chuckled.
"They gathered everyone but the Guardians of the Galaxy." said Rayman.
Sonic turned to Rayman in confusion.
"That's what you told Robin to do, find Doctor Strange and have him help gather a ton of allies?" said Sonic.
Rayman chuckled.
"I had a feeling something like this would happen." said Rayman.
Then another portal opened up and the Guardian's of the Galaxy emerged from it.
"And they gathered the Guardian's of the Galaxy." said Rayman.
