Crossover Chapter 1: Reunions. (Inspired by many crossover fanfics and an idea I'm working on with a fellow author. Credit goes to the authors of the crossover fics and BestCrossoverMovies.)

Sonic and his siblings were currently asleep in the backseat of the Royal Rider while Aleena sat beside them, awake and watching over them. Sonic then woke up and yawned.

"Good morning, Sonic." Aleena said with a smile. It was dawn and the royal family was currently on a road trip. Sonic looked out the window and looked puzzled for a bit. He saw they were driving through a neighborhood with small houses side-by-side.

He turned to Aleena and said, "I think we may have taken a wrong turn or something." Aleena then shook Manic awake.

"What is it, Ma?" the green hedgehog asked.

"Manic, are you sure you gave our driver the right directions?" Aleena asked.

"Yeah. Positive." Manic said, starting to go back to sleep when suddenly, without warning, the car suddenly jerked to a stop, causing the five hedgehogs to fall out of their seats and waking up Sonia and Sam.

"(YAWN) What's going on?" Sam asked, rubbing his eyes.

"Did traffic suddenly jam or something?" Sonia asked, pulling herself up. They rolled down the window and saw something that shocked them. A small blue house was halfway destroyed with a jet beside it.

"What in the world?!" Aleena said with shock as she and her family stepped out of the car. Suddenly, the door came off and a fat pink rabbit wearing a business outfit hopped out.

"Wow. That, uh, got outta hand, it looks like." he said. That's when a tall blue cat wearing a white shirt and a brown skirt rushed out, looking heavily ticked off.

"Yeah?! You think?! You just flew a flipping JET into the house as a wake up prank!" Then, a smaller blue cat wearing jeans and a tan sweater rushed out, followed by an orange fish wearing green shoes and a smaller pink bunny wearing an orange skirt carrying a small pink and yellow donkey doll.

"DAD! WHAT THE HECK?!" the blue cat yelled.

"This has gone far enough!" the orange fish shouted.

"Your pranking us has gone far enough!" the rabbit yelled. The bigger rabbit looked embarrassed before ashamed. The tall blue cat sighed in exasperation.

"Well, if we're gonna do something, we're gonna have to go to a hotel or something, which we don't have the money for!" she shouted in anger at the big rabbit. The whole Hedgehog family, except for Sam, gasped in surprise.

"Gumball?" asked Sonic.

"Anais?" asked Sonia.

"Darwin?" Manic asked.

"Nicole? Richard?" Aleena asked. This caught the attention of the five anthropomorphic animals as they looked in the direction of the hedgehogs.

"It is you guys! It's been far too long!" Sonia said as they walked over.

"Sonic! Sonia! Manic!" Gumball said as he and Darwin each gave them fist bumps before Anais gave all three of them a hug.

"It's been a long time, Aleena!" Nicole said, raising her hand.

"Sure has!" Aleena said, giving her a high-five.

"How's it hanging, Richard?" she then asked the bunny.

"(SIGH) Not good." Richard said before he walked off to mope.

Nicole sighed before she said, "I'll go handle this." and walked off to comfort Richard. At that time, the children were conversing with the hedgehogs about their recent adventures.

At that point, Gumball caught sight of Sam and asked, "Who's that?"

Sonia patted Sam's shoulder, "This is Sam. He was abandoned and Mom adopted him." she said.

"Nice to meet you." Sam said with a smile. After introductions were made, the house was repaired thanks to Aleena loaning Nicole some cash. By morning, the Hedgehog family had decided to stay with the Wattersons for a while.

At breakfast, Gumball asked Aleena, "What brings you guys to Elmore?"

Aleena took a sip of milk before she said, "We're just traveling through here on our way to Mobian Splash. It appears somehow we traveled dimensions on our way there."

"You guys have got to come to school with us! Last time, we couldn't let everyone else meet you cause of Eggman, but now everyone else can meet you guys!" Darwin suggested. Sooner or later, it was time for the kids to go to school. The five hedgehogs climbed into the Watterson family's station wagon and headed to Elmore Junior High.

"Let me come in, too. I'd like to help give you all a proper introduction." Nicole said.

"Sure thing, Nicole." Sonia said as they walked in. They headed to Miss Simian's classroom, where the rest of the class was sitting bored.

"Hey, didn't Gumball tell us he had some special friends of his coming today?" Alan asked.

"He's probably telling lies." Tobias said.

"It doesn't matter, because even if he isn't, I will not allow any special guests in my classroom!" Miss Simian said in a strict tone, making the class moan.

"But, Miss Simian, we have to! They've been excited about this for months!" said Principal Brown.

"I don't care! NO MEANS NO!" the grouchy monkey said as she took a sip of coffee. At that point, she saw Gumball and Darwin alone and quickly made her way back into the classroom before slamming the door shut and locking it.

"What's the matter, Miss Simian?" Penny asked.

"Nothing." the monkey lied. She then turned around only to leap back in fright when she saw Sonic.

"What's your deal?" the blue hedgehog asked.

"Who or what are you? How did you get in here?!" Miss Simian asked, pointing with a shaky hand at him.

"They don't call me Sonic the Hedgehog for nothing!" Sonic said, brushing his nose with his finger. Everyone else was in the classroom behind him.

"You didn't answer my question. How did you get in here?" Miss Simian asked again.

"I have super speed. I can get into a door the instant before it closes." Sonic answered, gesturing to himself before saying to Gumball, "Well, Gumball, are you gonna introduce us?"

"Oh, yeah." Gumball said before he turned to the class.

"Everyone, meet Sonic, Sonia and Manic. Some of you may have seen them when Eggman attacked here, but for those of you who didn't, here they are!" Gumball said as the class applauded and the Sonic Underground took a bow.

Darwin then gestured to Sam, "This is Sam, their newly adopted sibling." he said as Sam gave a shy wave.

Nicole then gestured to Aleena, "And this is Queen Aleena, their mother and the ruler of their home planet, Mobius." she said as Aleena bowed in greeting.

Upon hearing that, the rest of the class said, "Pleasure to meet you, Your Highness."

Aleena smiled as she said, "The pleasure's mine."

"Well, now that's done, so GET THEM OUT OF HERE NOW!" Miss Simian shouted loudly, making everyone cover their ears. Gumball looked upset.

Sonic stepped up to her, "Hey, who are you to make us leave?" he asked.

"I'm the teacher, and I say leave!" the monkey said as she pointed at the door before she pushed the five hedgehogs out. She slammed the door shut before she turned around and saw Sonic again, yelping and leaping back in fright.

"Told you." Sonic said.

"Hey, Sonic! Can you do a breakdance?" Banana Joe asked.

Sonic smiled, "Sure can." he said before he did a split and started sliding his legs around on the floor in a circle before he flipped upside down and balanced himself on his pointer finger before spinning as if he was a dribbling basketball. He then jumped back up into a ball and bounced himself on the floor before uncurling and landing on his feet.

"Ta-Da!" he said. The class applauded and whooped as Sonic bowed.

"And breakdancing isn't the only thing we're good at." Manic said as they summoned their instruments.

"Check this out." Sonia said before they started a tune.

(Sonic) What comes up must come down

Yet my feet don't touch the ground

Seeing the world spinning upside down

A mighty crash without a sound

(Manic) I can feel your every rage

Step aside I'll turn the page

Breaking through your crazy maze

Like a laser beam my eyes on you

(Sonia) Watch me rule the night away

Watch me save the day

Feel my storm it's getting close

Heading your way

(All) Sonic Heroes

Sonic Heroes

Bind you confine you defying your reign

Sonic Heroes

Sonic Heroes

Setting the stage for a hero's parade

(Sonia) I won't even hesitate

A second left to alter fate

(Manic) You try to strike but a bit too late

I got you hooked by my own bait

(Sonic) Watch me rule the night away

Watch me save the day

Feel my storm it's getting close

Heading your way

(All) Sonic Heroes

Sonic Heroes

Bind you confine you defying your reign

Sonic Heroes

Sonic Heroes

Setting the stage for a hero's parade

(Sam) You can bet there ain't no doubt

As the words spill from the mouth of a hero

I can chase another day

Fight you all the way

Like a hero

(Aleena) And together we stand strong no matter how

No one can bring us down...

Hey

(All) SONIC HEROES!

Sonic Heroes!

Bind you confine you defying your reign

Sonic Heroes

Sonic Heroes

Setting the stage for a hero's parade

Sonic Heroes

Sonic Heroes

Give us a reason and we're on our way!

The class whooped and hollered as they put away the instruments and took bows. Miss Simian then screamed in rage, making everyone look at her in shock.

"NO! NO! THIS CLASS IS SUPPOSED TO BE MISERABLE! YOU LOSERS RUINED EVERYTHING!" she yelled, jumping up and down in rage.

"Jeez, don't be so uptight!" Manic said.

"Uptight?! How can I be uptight when these two are making pathetic comebacks at being mothers?! I'll bet they've probably never even beat someone up for you brats!" Miss Simian shouted, pointing at Nicole and Aleena, who looked shocked.

"Don't talk to our moms like that, you ugly old brute!" Sam shouted, making everyone shout, "SAVAGE!"

Sam then started dancing arrogantly as Sonic chanted, "Savage! Savage! Savage!"

Miss Simian looked angry before Aleena told her, "Miss Simian, I'm afraid you've made a mistake. Ready, Nicole?" she then asked her friend.

"Yeah, she thinks we're just making comebacks at being moms, but…" Nicole started before Aleena started something.

(Song owned by LL Cool J.)

(Aleena) Don't call it a comeback.

I've been here for years.

Rockin' my peers,

Puttin' suckers in fear.

Makin' the tears, rain down like a monsoon.

Listen to the bass go BOOM!

(Nicole) Explosion!

Overpowerin'

Over the competition, I'm towerin'

Wrecking shop, when I drop

These lyrics that'll make you call the cops!

(Aleena) Don't you dare stare!

You better MOVE! (Shoves Miss Simian.)

Don't ever compare!

(Nicole) Me to the rest that'll all get sliced and diced,

Competition's paying the price!

(Both) I'm gonna knock you out!

Mama said knock you out!

I'm gonna knock you out!

Mama said knock you out!

I'm gonna knock you out!

Mama said knock you OUT!

YEAH!

The class clapped and said, "Yeah, get it!" as the children went, "WOOOOOAAAAAHHHH!"

Miss Simian growled before she said, "Fine then! You two and me, outside!" and ran and jumped out the window. Suddenly, there was a rumble before Miss Simian grew in size until she was the size of the building.

"HA! HOW'S THIS, LOSERS?! MY GROWTH POTION WORKS PERFECTLY!" she asked in a taunting voice.

"Well, she's certainly grown." Sonia said.

"Let's get her." Sam said before he and his family jumped out of the window, Gumball and Nicole following.

"Miss Simian, are you crazy?!" Gumball shouted.

"I'm not crazy, just EAGER TO CRUSH YOU!" the giant monkey said before she slammed her fist into the ground as the hedgehogs and cats leaped away, causing her fist to leave a huge crater that she tried to pull her fist out of.

"Take THIS!" Nicole shouted as she gave a strong kick to her elbow, making the bone crack a small bit and causing Miss Simian great pain as she pulled her arm out of the ground and clutched it with a roar. Aleena and Manic flew up and slammed down on her feet, making her leap into the air and fall back on the ground with her foot clutched in her hands. Sonia, Sam and Gumball then slammed their feet into her gut, knocking the air out of her. Sonic then jumped up and prepared a homing attack before Miss Simian shot up and ate him.

"SONIC!" everyone shouted.

It was muffled, but they soon heard from inside Miss Simian's stomach, "You're so gonna regret that! Hedgehogs don't make good snacks!" before she started convulsing in pain. After a few minutes, she threw up Sonic, who was holding a bottle of something green. Miss Simian then started to shrink back to normal before she fell unconscious.

"Yeah! Score one for Sonic and the Hedgehogs and Gumball and Nicole!" Sonic shouted before the whole school started to applaud. After Miss Simian was sent to jail, Sonic threw the bottle away, which was the potion. As the heroes headed back to the Watterson residence, they heard screaming and crashing. They looked and were shocked to see a giant Death Egg Robot Sentinel rampaging through the neighborhood.

"What the?! Did Eggman follow us here?!" Manic asked.

"No, he's in prison, remember?" Sonia asked.

"If that's not Eggman, then who is it?" Darwin asked. The robot then kicked a giant pile of rubble into the street to halt the evacuating citizens.

"Now, people of Elmore, praise your new ruler!" said a voice unfamiliar to the Hedgehogs, but all too well known by the Wattersons.

"It's her." Nicole said in a low whisper.

"Who?" Sonic asked. The robot's head then opened and out popped a small pod with someone in it. Sonic whipped out a pair of binoculars and looked at the pod and saw, to his confusion, a woman who was entirely orange except for her lips, which were blue.

"Felicity." Gumball said.

"Who?" Aleena asked.

"She's a snobbish rat who thinks she's superior to anyone else." Nicole said.

"Well, she isn't wreckin' this town with that Egghead robot." Sonic said as he got out of the car and ran to confront her. Meanwhile, the woman in question was floating in front of the terrified citizens.

"Elmore, I promise you, once you make me your ruler, I'll ensure you all are treated well, if you agree to do everything I say. I'll even run the Wattersons out of town." Felicity said.

"Felicity, knock this off! We don't want you as a ruler! And, while it is true that the Wattersons do screw up a lot, things around here just wouldn't be the same without them." the Mayor said.

Felicity grew annoyed, "If I can't get you to agree, I'll force you to!" she yelled before she shot a missile at him, only for Sonic to appear on the scene and kick it away.

"What the?!" Felicity asked.

"Felicity! Stop this!" Sonic said as the rest of the heroes ran over.

"You losers again!" the orange woman shouted, pointing at the Wattersons.

"Last time we met, you almost got me sent to jail!"

"Well, you did break multiple laws!" Gumball argued.

"Enough!" Felicity shouted before she flew back to the robot and fired a laser beam at the heroes, only for them to quickly avoid it.

"We need a plan." Gumball said.

"All right, we'll keep its attention and you try and find a way to disable it." Aleena said. Gumball nodded and he rallied his family to aid him.

"All right, listen, while Sonic and the others have her distracted, we'll sneak up behind the robot and look for a weak spot." Gumball said, to which his parents and siblings agreed. They rushed behind the giant bot while Sonic and his siblings attacked it from many different angles. Nicole pulled out a rocket launcher and fired it at the robot's back, but it didn't even scratch it.

"Hmm, try shooting its feet." Darwin said. Nicole tried it, only for it to lift up its leg and crush the missile. Richard then snatched it and fired at its arms, which were charred a bit, but didn't break.

"It's too heavily armored!" he screamed before Anais looked at its head and looked at its eye.

"That's it! HEY, GUYS, STRIKE THE EYE! THAT'S THE ONLY PART UNARMORED!" she called.

"You heard her! Let's do this!" Sonic called as he and his family jumped up.

"It's lights out for you!" Sonic said before the family started winding up in balls as if about to perform a Spin Dash.

"Family Homing Attack!" Sonic called as the five hedgehogs shot through the robot's eye and knocked Felicity out of the control spot onto the ground, where police were waiting. As Felicity was hauled away to jail, kicking and screaming furiously, the five hedgehogs and Wattersons were being hailed as heroes. The mayor of Elmore walked up to them and handed them certificates.

"Please accept these as a token of Elmore's thanks for defeating Felicity. You all will go down in history as our heroes and most honorary citizens." he said as Elmore applauded in celebration of their new heroes. Afterwards, the Hedgehog family piled into the Royal Rider.

"Do you have to go so soon?" Gumball asked.

"Sorry, kid, wish we could stay longer. But, I know we'll see each other again before long." Sonic said, giving him a thumbs-up. As the car started to move, the Wattersons started waving goodbye, with Sonic's family returning the gestures.
