Ladies and Gentlemen, a new idea for a fanfiction has come up and I couldn't hold back any longer, so it's a crossover of Sonic the Hedgehog and Mario and it's called:

Black Hedgehog and Siren Partnership

So yes, this story does focus on Shadow the Hedgehog and a partner from Paper Mario The Thousand Year Door. Enough with my rant now, here's the story. Enjoy!

All characters and stuff belong to their rightful owners.


OUTSKIRTS OF WESTOPOLIS:

The Ultimate Life Form known as Shadow the Hedgehog was just standing on the outskirts of Westopolis, enjoying the sun setting over the horizon, like he did when he had went through his amnesic crisis, and when the Black Arms invaded the planet. He managed to put all that behind him along with his past, and was just relaxing and enjoying his alone time.

It was then that a disturbing breeze in the air caused Shadow to sit up and take a glance around him to see if any mysterious beings were making an appearance.

To him, he saw no one, so he shrugged it off and lied back down.

It must be my crazy imagination. He thought to himself. That was until he then heard a loud whisper calling his name somewhere.

"Shadow…"

The voice made Shadow cringed as he got up and on his feet. He recognized that voice from somewhere… but could it really be? It can't be, could it?

Before he even attempted to call out who was calling his name, a mysterious creature appeared. It appeared to be… a black starfish floating in the air, and it had six appendages, and it had a crimson red eye in the center. Shadow was in disbelief as the creature acted as a projector and then a hologram of a certain alien overlord that Shadow knew too well, appeared as a hologram, with the horns, three eyes, and the works.

"Ah Shadow, it's been a long time." The creature hissed loudly.

Shadow couldn't believe it. He defeated and killed this monster a while back. In an attempt to save the Earth, he went into his Super Form and killed the monster that stood upon him now (although the monster was in a different form when he was killed).

"What the," Shadow stuttered, sounding shocked. "Black Doom… how are you here? You're suppose to be dead!"

Black Doom as he called himself, expected this from Shadow, so he let out a sigh and started explaining.

"You poor insolent fool," Black Doom hummed in amusement. "Have you forgetten that I'm immortal, I can't be killed."

"Well in any case, what do you want Black Doom?" Shadow growled, not wanting to deal with the arrogant alien overlord a second time.

"What do you think I'm here for fool," Black Doom hissed arrogantly. "I'm gonna claim you now as my personal slave! YOU WILL OBEY ME WHETHER YOU LIKE IT OR NOT FOOL!"

"Fat chance," Shadow sneered, ready to skate off. "The day I become your slave will be the day that pigs fly!"

"You don't have a choice Shadow," He hissed. "I created you with my blood! I can control you! YOU ARE MY SLAVE!"

"I already told you that you have no control over me Black Doom," Shadow snarled, just about set with this monster. "And I left the past behind me! Now if you'll excuse me, I have somewhere I need to be, AWAY FROM YOU!"

"Oh no you don't, YOU'RE MINE NOW SHADOW!" Black Doom roared as he lifted his hand out, trying to control Shadow, but to no avail since Shadow was already skating far away from him. "YOU CAN'T ESCAPE ME SHADOW! I WILL CAPTURE YOU, AND YOU WILL BECOME MY SLAVE!"

"Hmph, that's never gonna happen," Shadow announced as he got out his damn FOURTH Chaos Emerald, the green one, and then held it in his hand and rose it up high.

"CHAOS CONTROL!" Shadow shouted before escaping to a place far away from Black Doom.

"SHADOW!" Black Doom boomed, shaking up the entire area around him. "THIS ISN'T OVER! I SHALL HUNT YOU DOWN, AND I WILL FIND YOU!"

With that, Black Doom teleported himself, to find Shadow.


MEANWHILE, IN ANOTHER COMPLETELY DIFFERENT LOCATION:

"VIVIAN, YOU NIMCOMPOOP! COME DOWN HERE!" A shadow figure wearing a blue and white striped witches hat, known as Beldam shouted for her youngest sibling Vivian.

"Guh!" A much bigger, chubbier and tougher looking Shadow figure wearing a yellow and white striped witch's hat called out.

"Yes Marilyn, Vivian has to come and become my personal slave." Beldam said to other sibling who is called Marilyn.

Beldam, along with Marilyn and formerly Vivian, were of a group known as the Shadow Sirens, each could control a certain element. Beldam controlled ice, Marilyn controlled lighting, and Vivian controlled fire.

"VIVIAN," Beldam snarled angrily. "COME DOWN HERE THIS INSTANT AND BECOME MY SLAVE NOW!"

"Never," Vivian shouted from her bedroom. "I'm not gonna be your slave and allow you to take over this planet sis!"

Vivian, in her room, was shown like her sisters, but the most unique thing about her, was that she had not only a red and white striped witches' hat, but had pink colored hair that was in a curl.

With a look of aggravation, Vivian had had enough of her oldest sister's arrogant behavior, had to run away, and leave home. Truth be told, she remembered Beldam saying she gave up evil after The Shadow Queen was defeated at the hands of Mario, who Vivian had sided with. Beldam also promised to never mistreat Vivian again, or treat her like a slave. That eventually turned out to be a lie.

Without hesitation, Vivian departed into the shadows and left home for good. Beldam, getting impatient, was about to make a threatening punishment for Vivian.

"GUH!" Marilyn called out.

"What is it Marilyn," Beldam asked, as she saw her pointing to the window. Wondering what it was, Beldam looked out and was shocked and angered to see Vivian was escaping.

"VIVIAN!" Beldam roared, opening the front door. "YOU BETTER GET BACK HERE NOW OR YOU'LL GET AN ETERNITY OF PUNISHMENTS!"

"I'm sorry sis," Vivian apologized. "But, you're just too evil and arrogant for me to deal with anymore."

With that being said, Vivian then departed into the shadows, leaving a Beldam to fume.

"VIVIAN!" Beldam boomed shaking the area around her just like Black Doom had done. "YOU CANNOT ESCAPE ME YOU UGLY WHELP OF A SISTER!"

Turning to Marilyn, she called out to her.

"Come Marilyn, we are going to capture Vivian and make her our slave."

"Guh," Marilyn nodded her head as both she and Beldam departed into the shadows, chasing after Vivian.


Vivian was making her way far from her home, and Beldam. She was about to hit Twilight Town and reach the pipe for Rogueport, when she suddenly bumped into someone, knocking him down along with herself.

Shadow, who ended up in Twilight Town, was unaware of his location, but was just grateful that he was away from Black Doom. It didn't make him feel better that the mistreated Shadow Siren ran into Shadow and knocked him over.

"Oh no," Vivian quickly got up, dusting herself off. "I'm so sorry mister. I am in a hurry and was not looking at what was in front of me!"

She then helped Shadow up and dusted him off. Not paying attention to what she did, he had his attention on the lovely looking Shadow Siren.

"Uh, who are you suppose to be?" Shadow asked with a serious tone in his voice.

Vivian was about to say what her name was when someone called out her name.

"VIVIAN!" Beldam voice shouted as she emerged to surface, with Marilyn in tow with her. "You are coming home this instant, and your becoming my slave and you're getting an eternity of punishments."

"I said no sis," Vivian protested with her arms crossed. "Your mean and you are bullying me again after the promise you made to me and which you broke it voluntarily."

"Why you little, YOU BEST OBEY ME VIVIAN OR I'LL…" Beldam was cut short when she noticed Shadow standing to the side, looking moody as always. "And just who are you suppose to be, you inferior pest!?"

Shadow didn't take kindly to that comment, being the Ultimate Life Form and all that, and would have made a retort to Beldam, had that certain loud whisper not called out to him.

"Shadow!" The voice of Black Doom hissed as Doom's Eye appeared and Black Doom emerged from the hologram.

"Ugh," Shadow was now annoyed, since Black Doom managed to find him.

"That's right Shadow," Black Doom announced. "I found you, and now you shall become my slave fool!"

"I already told you that I will never become your slave," Shadow snarled angrily. "And I told you that no one tells me what to do."

"YOU WILL BECOME MY SLAVE SHADOW," Black Doom roared. "OR I WILL PUNISH YOU WITH AN ETERNITY OF PAIN AND TORMENT!"

While Black Doom was confronting Shadow, Beldam was angered with Vivian and her defiance.

"HERE'S YOUR LAST CHANCE VIVIAN," Beldam warned with a hint of arrogance. "YOU WILL BECOME MY SLAVE OR BE PUNISHED WITH AN ETERNITY OF PAIN, AND MISERY!"

"I told you, I'M NOT DOING IT ANYMORE BELDAM!" Vivian shouted, having enough with Beldam's harshness, which Shadow actually saw and was very amused by her standing up for herself. "YOU NO LONGER HAVE ANY CONTROL OVER ME!"

"Insolent pest," Beldam scoffed. "You best follow my orders…"

"…or you shall meet your doom right here and now." Black Doom coincidently said the same thing to Shadow that Beldam said to Vivian.

"NEVER!" Both Shadow and Vivian shouted together, as they than ran off, side by side each other, escaping Black Doom and Beldam.

"TRAITOR!" Both Black Doom and Beldam boomed, loud enough to cause a tremor to occur. Shadow and Vivian were far away from them as Vivian faced Shadow.

"Hey… huff… Mr. Shadow," Vivian huffed while running (or floating). "It seems that they both are wanting us as slaves. We have to escape together to get away from them."

"Hpmh, looks like we don't have a choice," Shadow huffed. "Either we escape together, or we become slaves to an evil alien overlord, and a shadow being of darkness."

"Mhmm." Vivian agreed.

"Let's get outta here then Ms. Vivian," Shadow stopped with Vivian by his side, as he got out the green Chaos Emerald. "Now hold on tight and don't let go of me."

"Okay," Vivian obeyed, grabbing hold of Shadow.

"CHAOS CONTROL!" In an instance, a green bright light occur, causing both Shadow and Vivian to teleport away from the arrogant monsters.

"Grrrrr… that traitor," Beldam grumbled. "What the heck was that anyway?"

"Chaos Control," Black Doom answered. "It's one of Shadow's 'oh so amazing abilities' that he uses to save people and he used it to save himself and your pathetic excuse for a sister."

"I'll say," Beldam agreed. "In any case, Black Doom, we must capture the both of them, and make them slaves."

"Better yet, how about a proposition," Black Doom hummed in amusement. "We team up and make the insolent pests known as Shadow and Vivian, and make them our slaves and take over this pathetic planet together, under the control of the Black Arms and the Shadow Beings."

"Hmmm… this proposition intrigues me so," Beldam mused, interested with the deal Black Doom is making. "I like it!"

"It a deal!" Black Doom said as he shook Beldam's hand, forming an alliance together.

"Okay, but how do we capture those two ungrateful traitors," Beldam wondered. "For all we known, they could be in another far away location, and Marilyn and I can't travel in that kind of style, and you can't either."

"I have a perfect plan, with one of my servants doing the honor," Black Doom announced. "BLACK BULL! I SUMMON YOU!"

A giant fat looking ugly Cyclops/bull dog monster known as Black Bull emerged from the shadows, making its ugly appearance.

"BEHOLD, THE WRATH OF BLACK ARMS!" Black Doom shouted arrogantly.

"Perfect," Beldam mused. "Just what we need to take out those two traitors."

"Exactly," Black Doom agree as he then saw Twilight Town, a town still in tack. "But first… COME BLACK BULL, BURN THAT ENTIRE CITY, AND ITS INHABITANTS TO ASHES!"

Black Bull along with some Black Arms soldiers started terrorizing Twilight Town, and its folks.

"What about me," Beldam wondered. "I don't have any associates like you Black Doom, no offense Marilyn."

"Guh."

"You can burrow my men," A strange voice called out.

"Huh?" Both Black Doom and Beldam looked behind them and saw another being emerged. It looked just like Shadow, but was all crystalline like and had green eyes.

"Who are you?" Black Doom and Beldam asked.

"I'm Mephiles, Mephiles the Dark," The creature known as Mephiles said. "And you are more than welcome to use my shadow servants to terrorize the human town civilization."

Suddenly, several of Mephiles' shadow servants came out and sided with Beldam.

"This is excellent, just what I need." Beldam mused.

"And after this, we'll make Shadow and Vivian our slaves." Black Doom stated.

"And teach this world a lesson," Mephiles added. "And rewrite the future!"

"Oh yes," Beldam snickered. "THIS IS REVENGE, VIVIAN AND SHADOW!"

"YES!" Black Doom hummed in amusement.

"MWA HA HA HA HA HA HA HA HA HA HA HA HA HA HA HA HA!…"

Black Doom and Beldam let out an evil and very arrogant laughter as Mephiles let out his own maniacal laughter as Twilight Town was being demolished by Black Bull, the Black Arms and Mephiles' associates (under Beldam's command) all while Shadow and Vivian were heading to a safer place, in Sonic's world.
