Prologue

Our story begins in a peaceful day. Well, mostly peaceful...but it was the day that the Black Arms—a race of alien marauders—invaded Sonic's world long ago.

Fortunately, they were stopped by the one, the only, the real hero: Shadow the Hedgehog! The black hedgehog faced many challenges and choices. But in the end, he saved the world from an alien destruction.

But in another time, another place...

A THIRD Black Comet had arrived in our universe, bearing more and more Black Arms. Even Black Death had resurrected from his previous defeat.

All these questions still remained. Who will stop these alien invaders? Will the Black Arms take over our universe? And what is their newest plan?

Well, 'gather around, friends, and let us tell you the story...

...the story of how a young man and his crew of toons and heroes from multiple worlds had come together to fought against the Black Arms!

The story of one science-fiction epic adventure filled with action, romance, excitement, comedy, movie parodying, mystery, and fan-service (LOTS and lots of fan-service)...

Gravity Falls, Oregon - From the world of Gravity Falls...

In the parking lot in the Gravity Falls superstore was a cart (with roof) with the Pines twins. In the cart was Dipper Pines and his sister, Mabel, sitting in a waiting state.

Suddenly, the sound of alien sounds is heard, Dipper lifts his head as he continues to listen to the sound coming from the satellite.
Mabel began to look around and asked "What was that?"

Dipper replied, "I don't know. But whatever it was, we need to return home and find out!"

"How?"

"With the help from our dimensional friends...," Dipper answered.

Mabel nods and Dipper begins to drive their way to the Mystery Shack. Whatever Dipper and Mabel discovered, they needed to get home to talk to their 'friends'.

South Carolina - Our universe (aka The Real World)...

Meanwhile, in South Carolina, in his home, Joshua Sumter woke up. He yawned as he got up with a happy, relaxed look on his face.

Joshua's Log: Stardate...um...never mind.

It's been some time since our crossover adventures*. We won...and I never felt so alive. With all the bad guys defeated, the worlds saved, etc., etc. and I get to relax for my perfect 'me-time'. The heroes from multiple worlds returned to their proper homes. And with that, life goes on. Just another day in the life of yours truly. It's a good feeling that I've sometimes get used to.

*The Project X Zone Movie & The Project X Zone Movie 2: Fate of Many Worlds

When Joshua got dressed, he soon got on his bed and began reading some books. He then heard a knock at his door. He stood up, walked over to the door, and opened it to show a man in a G.U.N. uniform.

"Mr. Joshua Sumter?" the G.U.N. soldier asked.

"Yeah?" Joshua replied, uncertainly.

"You're under the protection of G.U.N.," the man answered.

"What? WHAT FOR?!" Joshua half-yelled with a shocked look on his face.

The man told Joshua that he worked for the Guardian Units of Nations (G.U.N.). Under Commander Tower's orders, they were told that a mysterious THIRD Black Comet had come. That means the alien race known as Black Arms, had returned. So they tried to repel the invasion at any cost - by any means necessary.

To prove he was telling the truth, the man told Joshua to turn the TV on, revealing the secondary hive-mind of the Black Arms, Black Death, appearing on the News station.

"Attention, you inferior humans," Black Death began to broadcast on TV, "The time has come for the Black Arms to rise once again! We will seize control of the planet and soon everything else!"

Around the world...

From Japan, to France, to London, to Egypt, to China, the broadcast appeared on all the electronic screens as Black Death continued, "You humans are powerless against us! Remember this well, earthlings! There will no peace on your planets as long as we are around! This day belonged to the BLACK ARMS! No one can stop us!"

Black Death then added, "...not even the traitorous black hedgehog, Shadow. And that goes for the other worlds we are about to conquer and even that so-called inferior young human, Joshua Sumter"

As the broadcast ended, Joshua sighed. "Great. Now I know how Linkara deals with this stuff!"

Gravity Falls, Oregon...

Dipper and Mabel returned to the Mystery Shack and sits onto one of their beds and opened the laptop and then open up three screens.

"Emergency meeting, guys, Emergency meeting!" Dipper said, looking shocked, "Somebody wake up Sonic."

Three windows opened up—one had Sonic the Hedgehog, rubbing his eyes tiredly, obviously just waking up for he was also on his hammock, the other is Rock (aka Mega Man) at Light Labs, and the last one is Double D in his room at his home at the cul-de-sac.

"This is an emergency meeting of the Space Research Committee." Dipper said, "Roll call!"

Mabel, however, repeated loudly, "This is an emergency meeting of the Space Research committee. Roll call."

"Mega Man present," said the Blue Bomber.

"Double D, present!" Edd said, enthusiastically.

"Sonic?" Dipper asked, looking at his screen

Sonic yawned, obviously not happy about being woken up, and said, "Ready to get you."

"Then let this meeting commence" Dipper exclaimed before pumping his fist into the air, "Astro Semper Fidelis!"

Mega Man, Double D, even Mabel, both raise their hands, said in unison "Fidelis!"

Sonic, still a bit tired, mumbled, "Yeah...what they said."

Dipper clears his throat and said, "Alright, we started this committee with only one goal in mind."

"To get RICH." Sonic said, a grin appearing on his face.

"No." Dipper replied, deadpanned, "To boldly find what no one has found before!"

"And also get rich often," Sonic added.

Dipper rolls his eyes and then asked, "And for all the time they spent every night, what have they encountered?"

Sonic thought for a second and then answered, "Rocks."

"Rocks," Mega Man also said

"Nothing but a pile of rocks," Double D said

"And there was that thing that they thought was a UFO?" Sonic began, saying before Dipper could say something.

"That was a rock," Mega Man said, finishing Sonic's sentence.

Dipper waves them to be quiet and then said, "Well, take a listen to what Mabel and I heard today."

He send the three other members of the committee the sound he and Mabel encountered. The pulsing sound is heard which intrigues the other members.

Double D begins typing onto his computer and said, "Okay, I am beginning my scan on this"

Sonic types on his computer, "Let me see if I can get Tails to get a satellite to lock on it."

"All preliminary scans check out, this is fascinating." Double D said, finishing the scans and his eyes were wide in surprise.

"I've never heard those sounds this thing is giving out," Mega Man said, intrigued

"The gravitational whatsit on this thing has to be something dangerous," Dipper told them.

"All I have to say is whatever it is, it's gigantic," Double D said, giving his opinion.

"Okay, tracking complete," Sonic said and then added "Source code is confirmed as...the Black Comet."

"A 'Black Comet'?" Mega Man asked, confused.

Sonic tells Mega Man and others that he, his friends, and Shadow had some experience with the Black Comet and its inhabitants, the Black Arms, a race of alien marauders that attacked his world long ago.

Sonic nods and said "Yeah and, uh, is it me or does it look like it's gotten bigger?"

Dipper gives a puzzled look as he thinks. Just what have him and his friends discovered on the Black Comet? This could get serious very fast...

South Carolina-Our universe...

Meanwhile, at Joshua Sumter's home, Joshua opens the front door and looks outside for anyone.

Since he has been called by the Guardian Units of Nation (G.U.N.) about the Black Arms, he had to hide in his home.

Joshua growls and shouted, "Stupid black aliens!"

Then the phone ringed and he answered it, "Hello?"

"Greetings, you inferior human being," a voice appeared on the phone.

It belonged to Black Death, who was at his third Black Comet, sitting on a chair and he swivels round.

"Who is this?" Joshua asked, confused

"Oh, you may have help other heroes defeat their foes, human boy, but you have not evaded me." Black Death said, ignoring the question.

"No seriously, WHO is THIS?" Joshua said, still confused

"It's Black Death!" Black Death said, annoyed

"Who?" Joshua asked.

"Black Death, secondary hive-mind of the Black Arms. Got it memorized?" Black Death asked, getting more annoyed.

Joshua thought for a second before saying, "Oh, you're the alien leader from the TV brodcast! I have to hide in my own home because of you and your alien race."

"It's the least your humankind deserve, human," Black Death told him.

"Where are you calling from anyway?" Joshua asked, curious

"My comet, of course," Black Death replied, giving a grinning look before added "Not quite as cozy as your home planet, but it'll suffice till I send my army to your home world."

"Yeah? And just how do you supposed you're going to do that?" Joshua asked.

"Apparently they thought it wasn't the time for that right now," Black Death replied, embarrassingly.

"Or they thought YOU weren't very important," Joshua said and then added "Did they believe you were aliens? I admit you sound like Turrell from To Boldly Flee."

"Oh, so that's how it is, huh?" Black Death said, insulted. "Well, I will make you and your kind pay for helping Shadow defeat us. Consider this my vow."

As Black Death begins to do his speech, Joshua heard a noise coming from the living room and goes to investigate.

"I will not rest until your kind is in ashes. Oh, you have nowhere left to run and hide. I've marked every place and street you know. My Black Arms will climb every mountain, follow every streams, follow every rainbow!"

As he continues to head to the living room, Joshua asked Black Death, "Hey listen, by any chance, can you do anything else?"

"No" Black Death answered, confused.

Joshua then hangs up the phone and puts it back into his pocket.

He then walks around. He then sees someone sitting on a couch by the TV in the dark.

He slowly walks over to the figure, he grabs him and pulls the figure up into the bit of light there is and it revealed to be...

...Shadow the Hedgehog, looking a bit strange.

Shocked by this, Joshua said. "Shadow? What are you doing here? Are you okay?"

Shadow then said sounding a bit odd, "Help me, Josh! Take me home!"

"Um, Shadow, you are home. You're at MY home," Joshua said, thinking maybe Shadow has lost his marbles.

"There's no time," Shadow said "Search for my memory. Find the Black Hole."

"I think you might need a doctor" Joshua said.

Gravity Falls, Oregon...

Dipper and Mabel were building a gigantic ship with the help of their friend, Soos.

"I don't get it, guys," Soos said, "Why should I help you build a giant space ship to go find some aliens in space?"

"It's more than some aliens in space." Dipper replied, reassuring, "Our friend, Sonic, told us that some G.U.N. government's going to repel the invasion, so the people won't be in a panic or something!"

"What did this Sonic guy tell you?" Soos asked.

"That we're about to face a race of alien marauders that invaded his world some time ago," Mabel answered.

"Sounds sane to me," Soos said, scratching his head.

Suddenly, there was a dark, red cloud looms over Dipper, Mabel, and Soos, drawing their attention as they looks up towards it as the cloud and several others gather over Gravity Falls around some sort of opening up into them, and circle it for a few seconds, before a bunch of Black Arms fall out from the sky and begin laying siege to the city.

"We're doomed, right?" Soos asked.

"Yep," Dipper and Mabel answered in unison.

South Carolina...

At Joshua's house, two scientists were heaving up the unconscious Shadow. Joshua was on the phone.

"Yeah, the scientists are looking at him right now. We don't know what's with him all of a sudden," Joshua said, "Hold on, Velma. I'm getting another call."

Joshua hung up before answering, "Hello?"

"JOSH!" Dipper and Mabel's voice screamed as the sound of the black aliens invading in the background.

"Dipper? Mabel?" Joshua asked in shocked.

"JOSHUA! IT'S THE BLACK ALIENS! THEY'RE EVERYWHERE!" Dipper shouted as the sound of aliens coming to the Mystery Shack.

"Don't worry. Whatever you do, don't let them attack your home. Fight back! Try to grab anything that can be a weapon or maybe try to hide in the woods from them and wait for further instructions." Joshua said, giving them orders.

"Okay," Mabel replied.

Joshua ended the call as the two scientists walked over.

"Anything?" Joshua asked.

"Well, from all outward appearances, Shadow appears to be normal." The first scientist with glasses said, looking at his clipboard.

"The problem seems to be inside his head." The second scientist with a mustache stated.

"He seems to be suffering from a case of CCFCP." The first scientist said.

"Which is...?" Joshua asked.

"Coo-Coo For Cocoa Puffs." The second scientist answered.

"We will have to take him to our lab for examination." The first scientist stated.

"Well, thanks anyway, doctors." Joshua said.

"Oh, we're not doctors." The second scientist smiled.

The two burst into laughter before walking away, leaving a confused Joshua watching them.

"Thanks! Thanks a lot. Let me know if you wanna quote more To Boldly Flee anytime," Joshua called them, then asked himself. "Why do I talk to these people?"
