Shadow was floating through subspace once again, listening to one of his favorite songs:

watch?v=bMMV_RoEMxE

"I don't want to set the world on fire

I just want to start a flame in your heart

In my heart I have but one desire

And that one is you

No other will do..."

Shadow gave a deep sigh. "Ah, people don't appreciate golden oldies like this anymore. All they care about is if someone's got anaconda or something...

Shadow's communicator suddenly bleeped loudly, jarring him from his lazy floating.

"Guh...always at the worst time..." Shadow pressed a button on his display, showing the Elders in full view.

"Shadow, where are you right now?" Bugs asked.

Shadow took a quick look around the part of subspace he was in. "Ummm...somewhere between Hey Arnold and Venture Bros."

"Good, you're close by," Mickey said. "There is a literal giant rip in the fabric of space time near you, and you have to go close it."

"WHAT!?"

"Ah, don't act so surprised," Homer said. "This kind of stuff happens all the time. Just use some interdimensional space glue and patch it up before part of another multiverse leaks through."

"Wait - other multiverse?"

"What, did you think there was just one?" Homer said. "Sure, out multiverse is the main one holding all universes, but there other multiverse that have all the major universes mushed together. Whole other beings we don't know about exist there, which is why we need to patch it up before something finds the hole and tries to go through it."

"Okay...but I don't have any of that glue stuff you mentioned."

Homer scratched his head. "Hey guys, we gave Shadow that interdimensional glue, right?"

"That was your job, Homer."

"Uh-oh."

"Look, I'll go guard the hole until you can get me some of that glue, okay?" Shadow said. "I'll see you guys later."

With that, he switched off his communicator and floated off to find the hole.

I took him a while, but he eventually found it next to Yugioh universe system.

"Okay, time to stop any weird monsters from some whole other reality from getting through." He transformed his hand into his Subsonic Repeater, aimed at the hole, and waited.

ONE HOUR LATER

"Uggh...c'mon where are the Elders with that glue?" Shadow wondered out loud. His arm was getting tired from aiming at the hole. "At this point, I'd love it if something came out of that hole!"

At that moment, something flew right out from the hole, bumping into Shadow. Shadow flailed around for a second, then regained his composure pointing his gun at the mysterious stranger.

It was a girl, wearing a Jonin vest, camouflage pants, and combat boots. She had brown eyes and blond-brownish hair. Of course, the most interesting thing about her appearance was the Omnitrix on her right arm.

"Uhh, that was a really hard punch," the mystery girl muttered to herself. She took a quick look at her surroundings. "Huh, I don't recognize this part of Fanfiction World..."

Shadow cocked his Subsonic Repeater, and aimed it at the girl. "Hey! You're not supposed to be here, so I suggest you go back into hole you came from."

The girl looked at Shadow with a disapproving look. "Hey, I don't know who you are, but nobody gets to point guns at me!"

Almost instantly, the girl suddenly morphed into Madara, as the Sage of Six Paths.

Shadow blinked out of total surprise. "Wait, what?"

Madara/girl then slowly waved his staff in his direction. "Disappear." He simply said, as a wave of purple chakra energy burst towards Shadow.

Shadow quickly dodged, guarding his face as he took the brunt of the blast. "What?" he said, still surprised.

Suddenly, Madara was right behind him, and morphed into Big Chill, one of Ben 10's aliens. He quickly froze Shadow in a big block of ice.

"What!?"

Then, Big Chill morphed into THE HULK, and punched right though the ice, connecting with Shadow's jaw, and sending him flying.

"WHAAAAAAAT!?"

Hulk then morphed back into the girl, who immediately started doing a victory dance. "Whoo! Nice job guys! That's why no-one messes with Arabella!"

Shadow righted himself, and gritted his teeth. "Okay, that's it!" He immediately transformed into Ultimate X, his dark aura flowing.

"Whoa...okay, that's awesome, but also bad." Bella said.

Shadow enlarged his hand and stretched it towards Bella, gripping her tightly.

"Okay, like it or not, you are going back into that hole where you belong missy!" Shadow said in her head.

"Grgh...c'mon, let me go! I gotta stop him from getting through!"

"Him who?"

At that moment, another figure burst of the hole. It was man, wearing a cloak with a red hood.

"Oh Bella, my sweet angel, where are yoooou?"

"That him," The girl said, with a look of disdain.

The sorcerer turned to look at the Author and Guardian. "Ah, there you are."

"Ugh, Mafifas, give it a rest! I'm not marrying you. Ever!"

"Well, in that case..." He looked around the part of subspace he was in. "Hmm, looks like we've punched through into another dimension." A dastardly smile slowly formed on his face. "Bella, I'm going to give you a choice. Marry me..." The sorcerer suddenly shot four red balls of energy from his hands, which quickly went in four different directions. "...or this dimension will be destroyed."

"WHAT!? You madman!" Shadow cried, transforming back to normal form, releasing Bella.

"Really? Why do you have to be such a drama queen, Mafifas?" Bella said casually.

"Uh, he wants to destroy the entire multiverse. MY multiverse. The one I live in! WHY ARE YOU NOT PANICKING!?"
Bella gave Shadow a look. "Well, two reasons. One: I always kick his butt. Two: It can't be that hard, right?"

"Oh, it's quite impossible, Bella my dear," Mafifas said. "What I just shot were four magical energy bombs, capable of wiping out a quarter of this multiverse. They will all go off in two hours. You have till then to submit to my undying love for you!"

"Alright then, you evil wizard bastard. Me and mystery girl will find these magic bombs of yours, and save the multiverse." Shadow turned to Bella. "You will help me, right?"

"Eh, he's my nuisance, so I might as well take care of it." Bella said. "Not sure if I trust you though, what with the whole thing with the gun."

"Heh...sorry, that was a bit of a misunderstanding. I assumed you were hostile, since you were from a whole other dimension."

"Yeah..." Bella said. "I'd probably do the same thing, only with a flamethrower, some corn oil, and a rubber chicken."

They both laughed for a few moments.

"Name's Justin. I'm a Guardian of the multiverse, but you can call me Shadow X." he said, extending his hand.

"General Hyna, shape-shifting toon Author of Fanfiction World, but you can call me Bella." she said, taking Shadow's hand and shaking it.

"Nice to meet you." they both said.

"Jinx! You owe me a soda!" Bella said quickly.

"Er...maybe later."

"Hmm...fine, try to save this dimension. I'll be waiting right here, for your eventual failure." Mafifas said, summoning a chair and taking a seat.

"Okay then, let's do this!" Bella said, as she and Shadow flew off through subspace, searching for the first bomb.
