Robot Hedgehog: Chapter 1
A bunch of business men sat around a long rectangular table and were having an important meeting. The boss looked around the table before saying, "Alright gentlemen, we've decided to go with the design of an anthropomorphic hedgehog."
"Can we call him Mr. Needlemouse?" One employee asked.
"Not in public."

On a bright summer's day, Tails travelled down a clear road with trees on both sides and passed a Daytona USA sign in his Tornado which had transformed into go-kart mode. Sonic sat on the wing of the Tornado, holding some small drums. Tails suddenly then started singing. "Do da do da do do do do do dooooo!" Sonic and Tails then yelled, "DAYTONAAAAAAAAAA!" at the top of their lungs as Tails turned a sharp corner.
They sang again before Tails turned to Sonic and said, "Let's go away!" He nodded back with a reply of, "Let's go away." Before they sang "DAYTONAAAAAAAAAA!" in unison once again. They arrived in the city streets and swerved around the oncoming traffic.
As Tails spotted a few police cars chasing him, he said, "Let's go away!" Sonic nodded back and pointed ahead, "Let's go away!" They began to speed off as they yelled, "DAYTONAAAAAAAAAA!" once again. They travelled down an alley and soon down a path in a forest as they leapt off a cliff and drove down the rocky path before reaching the ground below and coming to a stop near the sea where they looked up at the shining sun.

In the vast wide open midst of the jungle, Tails and Eggman were racing each other in go karts along a muddy race track. They were approaching the finish line, far up ahead and were both neck and neck, with them both occasionally hitting the other. As they approached the finish line, Tails' go kart suddenly spontaneously combusted and broke down a few moments before the finish line while Eggman crossed the line and Omochao waved the white flag.
"Better luck next time, Foxboy!" Eggman said as he drove off.
Charmy suddenly appeared and placed some drums several feet away from Tails' kart. He then played said drums before yelling, "Game over yeaaaaaaaaaahhhhh!" then tapped the last cymbal.
Tails scratched the back of his forehead. "I'm not sure weather I should be happy or confused…"

Shadow the Hedgehog awoke in a status chamber on the Space Colony ARK as an alarm was blazing loudly in the background. A voice then greeted Shadow. "Ahh, Shadow, you're awake, we got big trouble, man."
"What's happened?"
"There's some like, chaos monsters aboard the ARK, and they're attacking pretty much anything. There's a machine gun right outside, feel free to pick up any weapons you find and blow them all to hell. Basically, if it moves, kill it, in an over the top and gory fashion."
"Thanks for the advice." Shadow left the room and picked up the machine gun before walking down a corridor containing three zombie Chaos figures which he fired at. He travelled up a slope and through a metal door before picking up a laser cannon. As he entered the next room, be began firing at zombies climbing down a wall, killing all of them except one which wouldn't die regardless of how much it was shot.
Shadow noticed a grenade further back behind him and blow him to bits before moving on. After several more minutes of blowing stuff up, Shadow entered one more room carrying a minigun, two sawn-off shotguns, a rocket launcher, a Uzi, six grenades, a laser cannon, and a rubber duck. One chaos creature spun round as he entered and threw his hands up. "No, wait, don't shoot!"
Shadow shot him shortly after and as the zombie fell to the ground, he asked, "Why?"
"Because you were Doomed from the start."

In Blaze's alternate dimension, Blaze arrived on Seagull Beach at Windmill Village and casually approached Marine who stood by the sea. "So Marine, what was it you wanted to see me about?"
"Crikey! You got 'ere pretty fast, Blaze." She replied.
"You said it was important."
"You bet! Check out my new boat!" she gestured towards a large white boat to her right. "Isn't it just ripper!"
Blaze inspected it for a few moments before saying, "Nice boat."

In the middle of a downtown area, an elite ninja wearing a typical black ninja outfit and sporting the Sonic Adventure 2 logo on his chest came driving down the street on a black motorbike and approached a hill. He swerved by a few cars, did a wheelie and hit the side of one car. He then spun 360 degrees before grinding down a conveniently paced rail, then he flipped off the bike, front flipped twice, back flipped three times, roundhouse kicked a flaming midget and landed in a red formula one car which drove by.

Knuckles sat in a locker room, wearing red boxing gloves when he received a letter which said, "King Boom Boo is waiting for your challenge!!" He sat up and left the room, soon arriving at the boxing arena where the audience were cheering. Knuckles entered the ring and up to his manager, Vector the Crocodile, who stood by his corner waiting for him.
"Hey Knuckles, you ready to go?" Vector asked.
"Yeah, I can take him. A little one, two, and an uppercut, and he'll be down for the count."
In the other corner, King Boom Boo was accompanied by another small ghost who then said, "Echidna stole my bike!"
Omochao, who was the announcer, stepped into the middle of the ring, joined by Knuckles and King Boom Boo. "Let's keep it clean, guys, now come out boxing! Fight!" He then flew off as Knuckles and King Boom Boo began. King Boom Boo continued to attack with upper right and left jabs which Knuckles dodged by ducking and moving in the opposite direction before punching him in the face right after dodging. Shortly after, Knuckles gave him an uppercut, causing King Boom Boo to stagger back and drop to the ground.
"Whoa! He just got Punched-Out!" One audience member said in shock.
Omochao flew over and quickly began counting, "Onetwothreefourfivesixseveneightnineten! Knuckles the Echidna is the world heavyweight champion once again!"
Knuckles raised his fists in the air as the audience cheered once more.

In the futuristic city of Metal City, Sonic, Tails, Knuckles, Amy, Shadow, Rouge and Cream were racing in futuristic go karts with the same design as extreme gear hover boards. With extreme turning, extreme boosting, extreme flying off of ramps, and extreme pit stops. The race itself was not so extreme as they rarely bashed into each other, but suddenly near the last turning as Cream was in the lead, Shadow sped past her, bashing her kart into the wall which then exploded due to sheer extremeness.
Omochao, who was the announcer at the time, then said, "Wow, it seems that she WipEd-out. Hehehe…and I've just been informed that if I say anymore stupid puns like that I'm going to get fired…"

In the middle of a city, a yellow go kart, and a red truck were driving along with the yellow kart singing. "Furformers, more than meets the eye! Anthrobots wedge their battles will destroy the evil forces of the Eggceptacons. Furformers!"
SA2, wearing a brown longcoat, stood next to another ninja and whispered, "Anthros in disguise." in his ear.
"Transformers!" The yellow kart and red truck drove off a ramp. "More than meets the eye!" they arrived in an empty parking lot moments later, where Sonic, who was a blue formula one car, and Amy, who was a pink buggy showed up before all four of them transformed into robotic versions of themselves.
"So what's the news, Knuckles?" Sonic asked while he glanced around the abandoned area.
"The Eggceptacons are back."
"Is that so?"
"It is so."
"Alright." Sonic said with a nod before pointing ahead. "Anthrobots, curl up, and dash out!" the four of them curled up into spin dash form and left the area.

Amy was strolling down a street in Station Square when she looked way up into the sky and saw an orange blimp which Big the Cat was riding, with the words, "Got Ring?" on it. She continued walking and approached Casinopolis, and as she looked up, she gasped as the only words she saw were, "Got Ring?" She quickly left the area, and ran into Cream by the station, who then waved. "Hi Amy, Got Ring?"
"I don't have any ring!" she yelled as she ran off with the speaker box yelling the words, "Got Ring?" She ran back outside and passed a shop with dozens of television screens by the window. Shadow was on the television. "I've Got Ring, have you?" he said before pointing at the screen.
She soon passed a little boy and his mother. The boy looked at the mother and asked, "Mommy, can I get Ring?"
"Of course you can get Ring, Tommy."
Amy continued running across the city, covering her ears and trying to escape the dreaded 'Ring' as she saw it everywhere she went. She eventually stopped by a tree in a forest, and looked far ahead to see Sonic speeding towards the area. Sonic stopped beside the tree and turned to Amy before saying, "Hey Amy, Got Ring?"
Amy's eyes became wide with fear. "W-what?"
"Got Ring?" He said once more.
Amy ran off screaming, leaving Sonic utterly confused moments before he shrugged. "Whatever, I guess I'll just play against Eggman online again."
It then cut to a scene of SA2 smoking a pipe with a book in his hand as he sat in a chair, by a fireplace which lit up the room. SA2 closed the book and removed the pipe from his mouth. "And so, Amy was eventually driven insane with all this talk about getting rings, when in reality it was just an awesome video game."
He cleared his throat before yelling, "EEENNNDDD!"
