I hope you guys enjoy my 2nd Pokemon/Sonic The Hedgehog crossover!

NOTE: This is a Pokemon crossover with the characters of the regular Sonic universe. Not the Sonic Boom universe.

Death Egg MK III

"Ho ho ho!"

Evil laughter echoed through the control room as the mastermind stood in his space station. His blue eyes were glued to his control panel a percentage bar charging his latest weapon. Pointing towards to peaceful planet of Mobius, was a weapon charging up for destruction.

"50% charged!" The villain exclaimed.

*BEEP! BEEP!*

The room began flashing red as an alarm blared loudly to the evil genius. An alarm signaling the presence of an incoming enemy. The genius pressed a button from his console; which turned on the security monitor in front of him. From the comfort of his seat, he saw the blue planet slowly rotate till he saw the threat approaching his base. Soaring through space looked like a yellow comet, but it was far worse than a speeding piece of ice.

"SONIC!" A voice cried.

The villain turned around and gave a cold look towards his captive. Locked up in metal shackles held a yellow two tailed fox to the silver wall..

"You're finished, Eggman!" The fox said.

"We'll just see about that, Fox Boy!" Eggman responded with no worries.

He turned back to his console and pressed another button, activating one of the stations defenses. With the weapon only at 60%, he needed to buy out some time. He needed to distract the soaring animal.

"Fire the missiles!"

Outside the Death Egg

"Hang in there, Tails! I'm coming!" Sonic called out.

As the golden hedgehog blazed towards his arch-nemesis's space station, he gazed at the egotistical face of it. A humongous Eggman face smiled at Mobius with eyes that looked like huge craters and a long stretchy mustache stretching across the pointy nose. Although it was a new fortress the doctor built, its design was identical to the previous Death Eggs.

"What took the welcome party so long?" The hedgehog smirked, seeing the hatches opening up.

Hundreds of doors opened up for the hedgehog, releasing a storm of deadly missiles out to space. If there was somebody else going after Eggman and saw a gigantic supply of missiles, they would retreat in a flash. But to Sonic, the missiles were going to be like going through a fireworks display.

Thanks to the seven Chaos Emeralds he had gathered during his latest adventure, Sonic felt like a god. His body (that was once blue) was filled with the power of chaos, protecting him with a powerful aura. Without a care in...out of the world, Sonic went through the assault, evading some of it for fun.

He took the center opening and proceeded onward through the deadly station. Not just for his best friend's safety, but for the safety of their world.

Back in the Control Room

"He has entered the egg, Boss!" A red and black robot informed his maker.

"I saw that!" Eggman shouted.

"If he reaches the Egg Cannon's power source, it's all over!" He exclaimed.

"Duh!" Tails muttered.

"Don't make me reactivate him." The doctor groaned.

Suddenly, an idea was hatched from inside Eggman's head. His look of frustration quickly changed to disbelief. An evil chuckle was let out as he processed the threat he spoke. With the percentage reading 75%, he slammed a fist onto a blue button from the console, releasing his trump card.

*BOOM!*

The door busted open, startling the doctor with the hedgehog's arrival.

"SONIC!" Tails smiled at his friend.

In the glowing flesh, he had come. Overwhelmed by the immense power surging behind him, the mad doctor slowly turned around, spotting his glowing foe. A cold stare was all he saw through the shining aura with his red eyes staring him. With a flick of his left hand, he shot the metal shackles that chained the fox, freeing him from his prison.

"What's up, Eggman!" Sonic smirked.

Without another word, Tails rushed out of the room. He knew that in a matter of moments, something was going to hit the fan. Whether Sonic wrecking the room or a battle was going to occur, it was too dangerous to hang with the super hedgehog. However, it didn't meant he could stop Eggman's scheme.

"Uh oh." Tails whispered, halting in the middle of the hall.

"Someone's coming."

The sound of a engine rang in the fox's pointy ears, alerting him to go hide. Only problem was there wasn't a spot to hide. The only safe place was the high ceiling. As fast as he could spin his two tails, Sonic's partner took to high altitude and landed on top of a ventilation duct above.

Overwhelmed by the growing noise, Tails stood quietly with his red and white shoes hidden from any kind of sight. The engine grew louder by the second until it instantly stopped literally beneath the vent. Tails took one glimpse down to the floor and recognized the wicked machine. Eggman's trump card had arrived and was ready to do a sneak attack on his enemy.

One glance was all it took for Tails to notice the one who captured him for Eggman. A small blue robot that looked like Sonic stood in silence, making its move. It then powered itself up with purple energy. A purple aura engulfed the doctor's greatest creation, gearing him up for an intense battle.

"Hope Sonic is ready." Tails prayed.

Eggman's trump card hauled away to where his enemy was, giving the two tailed fox some time to escape. He gently went back down and continued onward through the Death Egg. It was too late to warn Sonic about the approaching danger, but there was still time to save Mobius. There was still time to dismantle the Egg Cannon and to do that, meant removing its power source.

"Hang in there, Sonic! I'll be right back!" The fox exclaimed while running off to the core of the station.

Back to Sonic

"I'll give you a running head start out of here." The hedgehog generously offered the scared villain.

"GAAAAAAHHHHHHH!"

A million volts of electricity were suddenly shot Sonic from behind. Extraordinary pain surged his super powered flesh, hurting him greatly. He was invulnerable towards most hazards, but even he had some weaknesses. Electricity was one of those weaknesses. The electricity ceased firing, knocking the real Sonic on his knees.

"There can only be one Sonic."

There was only one being Sonic knew who would say that and he was standing behind him. With little strength he still had, he rolled around and saw the one who sneak attacked him. Through the purple aura, he saw Eggman's greatest robot. A blue artificial robot with glowing red eyes staring down at the real animal. He had a metal, lifeless mouth with a pointy, silver nose. Skinny limbs that were his arms and legs were attached to the stomach; which was where his engine was located. Lastly, his feet were designed to look like Sonic's shoes. Coded in red with a white stripe, the robot kicked his foe out of his way, sending Sonic across the room.

"Why, thank you, Sonic!" Eggman smirked.

"Go get him, Metal Sonic!" He ordered.

The cocky fat genius ran out of the room and made his way to a safer sector of his base. One that would be destroyed during the intense battle.

As the real Sonic got back on his feet, his robot copy entered the room normally. Seeing the pain he had inflicted to his target, the robot clutched his metal claws, seeing his victim in pain. A black mark had been made on Sonic's beige stomach as he felt it through his white gloves.

"Not bad!" He commented on the robot's progress.

"But it's gonna take a lot more than a kick to end me!" He replied.

Sonic then proved his own point to Eggman's machine by stretching himself out. He thrust his arms backwards and felt the increasing burn surging through his blood. He screamed for power as the Chaos Emeralds fueled him up some more, increasing the aura around him.

"Ready?" Sonic asked his foe.

Metal Sonic answered the rodent by copying his move. Just like the real Sonic did, the robot built his strength up even further. The more he charged up, the bigger the purple aura grew. He then resumed staring at the real hedgehog for his word.

"Let's do this!" The fleshed animal smirked.

The Core

"There it is!" Tails smiled, finding the area.

Beyond the narrow walkway was the power source of the Death Egg MK III. Illuminating the center room of the space station was the ancient treasure of the decease echidna tribe.

"The Master Emerald!" The fox exclaimed.

Shimmering with green sparkles laid a large green diamond inside a sealed tube. A diamond that held the power to control the seven Chaos Emeralds was now being used to power up Eggman's base. Tails knew exactly what needed to be done from what he saw. He needed to remove the emerald out of the core, but first he needed a way to open the tube.

"Maybe that computer can help." Tails spotted next to the core.

*BOOM!*

A loud explosion from above shook the area wildly. Knowing that it was the two Sonics causing the sudden ruckus, Tails held onto the right side handrail of the walkway and waited. As the floor shook uncontrollably beneath the fox's red and white shoes, destruction ensued. Pieces of debris rained down from the ceiling, sending dust along with them. The small earthquake began to die down, slowly stopping the rumbling Tails felt.

"Better get that emerald before Sonic demolishes the whole place!" The fox noted.

With the predictions of more rumblings to come, Tails cautiously released his grip on the steel rail. His white gloved fingers slowly unwrapped themselves from the dark blue bar as he took another glance at the core. He then spun his two tails and proceeded to the objective.

"Hopefully this computer will shut down Eggman's cannon." Tails prayed, turning on the computer in front of the core.

A holographic screen came on, displaying a menu of commands. As fast as Tails could type, he issued the computer to open up the sealed tube that imprisoned the Master Emerald. The command was granted as the glass was rolled up into the upper part of the core, partially freeing the big diamond.

"Great!" Tails cheered.

*BEEP! BEEP!*

"WHAT'S GOING ON?!" The fox screamed through the blaring alarm.

"WARNING! WARNING!"

"EGG CANNON FULLY CHARGED!"

"OH NO!" Tails cried.

Overwhelmed by the sudden event, the fox frantically entered "deactivate" into the computer. His right hand was ready to slam the "Enter" key, when a big force of mass ribbed him in the left side. He tumbled to the right side of the computer till he felt a piece of debris stopping him.

"Thank you, Tails!" A familiar voice spoke in a sarcastic manner.

While feeling a little stunned by the tackle, the two tailed fox saw who did it. Still wearing his red jacket with a white zipper in the back, was the evil genius who also escaped from the tow Sonics.

"Eggman!" Tails gasped.

"You were so close, but it looks like I'm finally going to win!" The doctor bragged, typing away.

"You haven't won yet!" The fox said, charging at the fat human.

Without even looking at his minor threat, Eggman pimp slapped Tails. Sonic's partner felt excruciating pain across his face as the doctor's right glove smacked him hard. He flew back hard. He flew back to the debris and fell on his butt, clenching on his nose.

During that moment, it felt like the end. Not only was the mission about to end, but the end of Mobius as well. Memories of the many inhabitant animals went through the fox's mind. He remembered the times being with Amy and Knuckles on Angel Island. A floating island in the skies of Mobius where the red echidna guarded the Master Emerald. But more importantly, Tails was going to be haunted by his soon to be failure.

"I'm sorry, Sonic." Tails thought, curling himself to cover his ears.

He bent his legs towards himself, when he felt something underneath his left leg. A rough mineral object was felt as he grabbed it from the floor and examined it.

"It's just a rock."

"A good sized one, but what's a rock's going to do?"

"WAIT!"

Suddenly, Tails had an idea. His eyes widely gazed upon the pebble he found. A mere pebble that he was going to toss aside, but instead toss forward. He then glanced at the Master and realized he wasn't defeated yet. There was still time to save Mobius, but it was going to e risky. The planet was now riding on one small rock.

"Sorry, Knuckles."

"Fire the Egg Cannon!" Eggman shouted.

Without a moment to wait, Tails ran towards the Master Emerald and threw the rock at it. The tiny mineral flew into the green light, hitting the source upon impact. By the time Eggman smashed the "Enter" key on the computer, it was too late.

"Why am I not hearing the cannon firing?" Eggman wondered.

"GAAAAHHHHH!"

The doctor's heart sank rapidly when he saw the computer screen. Racing against his heart, was the Death Egg's power leaking away. The percentage kept on depleting until it reached zero, shutting down the power of the base. Before Eggman cold react, the room became pitch dark. The computer died along with all other electronics in the station. The robots roaming around were unaffected to the power loss, but all lights, computers, and weapons were out, including the Egg Cannon.

"Where's the emerald?!" The villain cried.

"You lose again, Eggman!" Tails gloated, holding the Master Emerald.

Eggman saw the flying diamond and grabbed it from Tails without any hesitation. The two then began to fight for the treasure, tugging it to either side.

"Let go!" Eggman grunted.

"I-it belongs back on Angel Island!" Tails groaned.

The two kept on pulling their prize against each other until something unexpectedly happened. The legendary Master Emerald began to shine white, freezing the holders in place. Unable to move as the light swallowed them.

"SONIC!" Tails called out loudly.

"TAILS!" The hedgehog answered.

Both Sonics arrived to the action, only to see their partners fade into the light. The real hedgehog flew to his best friend to pull him away, but the force became too strong. It engulfed him too along with Metal Sonic as it grew bigger throughout the area. But it didn't end just there. It continued to grow non-stop, consuming everything in its radius. Every robot and machine was soon caught till there was nothing left. It didn't take long for the light swallowed the entire Death Egg with its glow. Every inch of Eggman's base was consumed by the Master Emerald's light, illuminating the dark side of Mobius. To the creatures down on the peaceful world, they thought it was already daytime. Little did they know that Eggman's base was about to disappear. Disappear to the far reaches of space. Never to be seen again as it vanished away to wherever it was going to be.

Please Review and Comment!

Before anyone starts requesting me to add in characters, I have some bad news. Due to the amount of characters I added in "Pokemon X", I decided to not add any characters in this story. Amy, Knuckles, and maybe Dawn will be added, but that will be it.
