Prologue

It was a dark and stormy night. High up in the clouds, reaching the mountain peaks, is Angel Island, an island of mystery. Some say it's not of this planet. Others say it's from another dimension…but if one were ever fortunate enough to actually visit the island, its only inhabitant would tell you that those are nothing, for he is the only one who knows the truth behind Angel Island, for at its center sits the Master Emerald, a giant, green gemstone, glowing in all its brilliance…and sitting before it sits its guardian: Knuckles the Echidna, who is…

"ZZZZZZZZZZZ…!"

…sleeping on the job.

My name is Knuckles. Knuckles the Echidna…and as far back as I can remember…probably since I was just a child, I've been sitting here on Angel Island in solitude, guarding the Master Emerald from anyone or anything that dared to harm it. Honestly, I don't know whose bright idea was it to put me in charge of guarding it…but if that is to be my destiny, to be stuck on this island forever…then so be it.

Besides, what could happen?

SMASH!

Knuckles snorted in alarm as he sat up, accidentally swallowing the twig he had in his mouth.

"What the heck?!" the echidna questioned as he whirled around, only to gasp upon seeing a strange-looking creature standing before him. It stood on two legs, like a humanoid, with glowing light green eyes. Its arms hung at its sides with the claw-like fingers on each hand, but what stood out most was the fact that the creature looked like it was made entirely of water, with a pink brain being seen right in its head.

Behind, a tiny little ball of orange light fluttered away into the distance.

"Hey!" shouted Knuckles, pointing his fist at the creature. "Who are you!? What are you doing on my island?!" At that moment, the crimson-furred echidna gasped in horror upon seeing the one thing he feared: the Master Emerald shattered into pieces!

"Oh, no!" Knuckles cried. "The Master Emerald! It's destroyed!" He then turned and growled at the mysterious intruder. "You…you did this, didn't you?! I ought to…RAAAAAAARRRGH!"

With that guttural roar of fury, Knuckles rushed the creature with his fists reeled back, but the creature jumped over him, at least 9 feet in the air before coming back down and knocking the echidna back, causing him to go tumbling down the stairs.

"OOF! UGH! URGH! AAH!" Knuckles grunted as he fell down the steps and eventually landed on his head. "Unh…thank goodness for hard heads…!"

Shaking off his pain and disorientation, Knuckles went rushing back up to the shrine, but when he got back up there, he saw the creature, melting itself down into a puddle, its green eyes narrowing at the echidna almost hatefully before it soon slithered away.

"Hey! You get back here!" Knuckles barked as he tried to chase it, but it was already gone. "Dang it! What the heck was that thing, anyway?!"

RRRRMMMMMMMBB! All of a sudden, the ground shook beneath Knuckles' feet, causing him to gasp.

"Oh, no," he whispered. "I was afraid of this…without the Master Emerald's power, Angel Island will fall into the ocean!"

In his panic…Knuckles failed to notice the tiny ball of light from earlier, flying away into the distance. All he could do was grab onto something tight as Angel Island rumbled and shook as it began to plummet towards the sea, faster than one could say "Red Hot Rock" and landed with a titanic crash, sending massive waves throughout the ocean.

"Ugh…" Knuckles groaned as he found himself at the bottom of the stairs, once again on his noggin. "Okay, this is just getting embarrassing."

He then grunted as he stood up, looking out towards the bridge that would take him to the mainland…leading towards the Mystic Ruins.

"Well…I guess it's not so bad," the echidna mused, rolling his shoulders so they would pop. "I actually have talked a lot about coming here…to myself, anyway. Besides, the pieces of the Master Emerald won't find themselves, so I have to start somewhere."

On that, Knuckles began his epic search…

Meanwhile, deep in the lush jungle of the Mystic Ruins, there sits a small hut made of old logs and a roof made with palm leaves, and in that little hut…sits one big purple cat, appropriately named, well…Big the Cat.

"ZZZZZZZ…fish…! ZZZZZZZZ…!" the big purple feline snored.

After a long day of fishing near his favorite, Big tired out rather quickly. It was in his nature, seeing as how he was quite the lazy fellow. No one could blame him, really. Fishing is said to be a relaxing pastime, that is if you're not one of those competitive folks.

As Big snored away, the ground suddenly trembled, and while it wasn't enough to rouse the large cat from his slumber, it was certainly enough to startle his little friend, Froggy. As the little amphibian looked around, he spotted what looked like water rising up from the stream.

'That doesn't look good,' thought the little frog. 'The stream wasn't that big earlier today…'

Curiosity overcoming caution, Froggy hopped off of Big's belly and went outside to investigate.

'Hmmm…nothing else unusual out here,' he thought before he suddenly spotted something. 'Wait…what's that?'

What it was a strange blue puddle of some sort…and it looked like it was moving on its own. In fact, it was slithering right towards him!

Froggy let out a croak of alarm, but before he could turn and run…GULP! The puddle seemed to leap into the little frog's mouth and force its way down his throat!

"Unh…huuuuh…!" Big yawned as he suddenly stirred, sitting up and scratching his white-furred chest. At that moment, he spotted Froggy. "Huh? Froggy? What are you doing up so late, buddy?"

Froggy just sat there, frozen and eyes fixated, and that's when Big noticed something strange: last he checked, frogs didn't have tails, especially a long tail with a diamond-shaped tip.

"Hey, Froggy," Big said, confused. "Where'd you get that weird tail from?"

'Big…help me, you dummy…!' thought Froggy, turning himself around and hopping behind his friend before he found the dazzling yellow gem that Big found yesterday morning and kept it as a lucky charm, but it was not just any dazzling yellow gem: Big had found a Chaos Emerald.

As Big turned around, he heard a GULP sound and gasped in shock as he saw Froggy swallow it!

"Hey!" the cat cried. "What'd you do that for, Froggy?! That was my lucky charm!"

'I'm not doing this on purpose!' thought Froggy as he turned around and hopped away. 'It's this tail! It's like it's got a mind of its own!'

"Wait! Froggy, come back!" cried Big as he tried to follow him, but being such a hefty feline, he seemed to run out of breath rather quickly. As he did, he watched in concern as his little amphibian companion just kept bounding away. "Oh, Froggy…what's wrong with you? You and I have been friends since I was just a kitten…!"

Sniffling, Big wiped away his tears and put on a determined expression, that was rarely ever seen.

"Don't worry, buddy!" he declared. "I'll bring you home and we can still be friends!"

A pause…but then Big's ears drooped and his eyes hooded sleepily.

"But first…a little nap."

FWUMP! He then flopped down on his back and snored away.

Later that night, in the big, busy city of Station Square, people are still walking along the streets. Most would be asleep by now, but even the nightlife of Station Square proved to be eventful. In fact, a police helicopter is hovering above the buildings…with a familiar little ball of light floating after it.

At that moment, a blue blur raced by, hopping across rooftops and jumping off street signs. As the figure landed upon a rooftop, it is revealed to be none than Sonic the Hedgehog, who had recently been on vacation until tonight.

As Sonic stood up on the rooftops, he spotted the helicopter blitzing by.

"I'm back for only 5 minutes, and already something's up," the hedgehog said before smirking. "Just the way I like it!"

On that, he heard the wailing of sirens coming from somewhere nearby, and as he looked down, he saw police cars and SWAT team trucks, tearing through the streets. One even almost hit a woman had she not gotten out of the way in time.

"Okay," Sonic said. "Now I GOTTA check this out."

And away he leapt.

At the First National Bank of Station Square, the police had the area surrounded, guns trained on the intruder: the very same creature that attacked Knuckles on Angel Island, which stood upon a roof, glowering down at the law enforcement.

"You are completely surrounded!" shouted the chief through a bullhorn. "Put your hands in the air and get down on the ground!"

The creature seemed to hiss at them before it leapt down and landed before them.

"You asked for this!" the chief shouted. "All right, men! OPEN FIRE!"

BANG! BANG-BANG! BANG! On that order, the police and SWAT teams began to fire their guns at the creature. However, as the bullets made contact…they fell through the being's body while the creature itself remained.

"Uh…Chief?" asked one of the officers. "I don't think it's working!"

"Guns are useless against that thing!" the chief cried. "RETREAT! ALL PERSONNEL, FALL BACK!"

"YOU DON'T GOTTA TELL US TWICE!" the other officers shouted before they got back in their patrol cars and sped off…leaving Sonic to face the creature alone, an almost smug grin on the hedgehog's face.

"This should prove entertaining," Sonic said. "Been a while since I had some fun. All right, you walking puddle! Bring it!"

BOSS: CHAOS 0

Sonic charged at his opponent, who leapt over him, the same way he did when Knuckles tried to attack. However, this time, his arm stretched out, trying to grab the hedgehog, but as always, Sonic proved to be too fast. He jumped over the tendril-like arm before curling up into a ball, preparing to use his Spin Dash attack, but as he sped through Chaos 0, he realized it made no effect, for his liquid body began to repair itself.

"Okay, that obviously didn't work," Sonic noted, but then he gasped as Chaos 0 hit him in the face with his arm, smacking him into a wall. "OOF! Ugh…okay, not cool…!"

Chaos 0 seemed to hiss at him before stretching his arm out, once again, but once again, Sonic dodged the attack, leaping up high into the air, and when he did, he looked down at Chaos, whose glowing green eyes glared up at him. That's when the blue hedgehog spotted something: Chaos 0's brain.

"I wonder…" Sonic muttered before curling up into a ball and hurtling towards Chaos O's head, landing a Homing Attack on the creature's brain and causing his body to splatter. "Yes!"

However, it proved to be too soon to celebrate, for Chaos 0 soon reformed himself and leapt up onto a flagpole, stretching his arm out to grab Sonic, again, but the Blue Blur dodged left and right, and even let out a mocking yawn of boredom.

"Got any more tricks, buddy?" Sonic asked, only to be smacked away into a wall, once more. "…Okay, I really gotta learn to keep my mouth shut, sometimes."

Chaos 0 jumped down, glaring at Sonic and moving in to try and finish him…"try" being the keyword.

ZIP! BOOSH! Sonic, using yet another Homing Attack on Chaos 0's brain and sending him back into his puddle form.

"Oh, yeah!" he cheered. "C'mon, big guy! I can do this all night!"

Chaos 0 growled, seeming frustrated with Sonic's cockiness. He stretched out both arms and began to whirl around like a helicopter rotor with his fists glowing purple, but Sonic only smirked as he jumped over the appendages, at first with both legs, and then using one leg each, like he was playing Double-Dutch.

"C'mon," Sonic said, looking out to the fourth wall. "Even heroes gotta have fun, once in a while."

Soon, Chaos 0 stopped and began wobbling around, dizzily. Smirking, once more, Sonic saw his chance.

"And now for the win!" he shouted before he leapt up and kicked Chaos 0 in his brain, this time sending him against the wall, splattering all over like a popped can of chili. The creature slid down to the ground before slithering off towards a sewer drain.

"C'mon, you big drip!" Sonic taunted as he followed. "Where do you think you're goin'?!"

Soon, Chaos 0 disappeared beneath the grate, leaving Sonic confused.

"What was that thing?" he asked.

High up on a building to Sonic's left, a shadowy figure grinned evilly as a white gloved finger brushed his orange-brown mustache.

"You know nothing, fool," he muttered. "It's Chaos…the God of Destruction! BWAHAHAHAHAHAHAAA~! AHAHAHA-AHA-ACK-KOFF-KOFF! Urrgh…I gotta lay off that gelato…"

SONIC ADVENTURE

Yeah...I just couldn't help myself. XD

Sonic Adventure was the very first Sonic game I ever played. That was back in the year 2001, when I was only 5. Of course, back then, I had absolutely no idea what I was doing and my brother took over for me. The second Sonic game I ever played was Sonic Riders: Zero Gravity, followed by Sonic Unleashed, Sonic Riders, and...actually, that's it.

Anyway, I'll still be doing One Piece stories. As soon as The Island of Children is done, I'll be uploading One Piece: Unlimited Adventure, as promised. ;)

Review, please!
