After consulting (See that? Funny!) Fellow author SummerAtMidnight, who is not only a brilliant writer in her own right, but also my cousin, I thought I'd take a break from my other fics and post this just for a laugh.

Thought I'd be the first with a cross-over between SONIC THE HEDGEHOG and BBC's SHERLOCK.

Oddly weird but fun!

The Case of Purple Anarchy. (Working title.)

Summary.

During a fight with Professor Eggman, young Aleena is transported to the Void via Chaos Control. Shocked to find it disappearing at an alarming rate she learns the only way to save it, and her family's legacy, is to use the last of the Chaos Emeralds. The lost Grey one. Problem is, she has no idea where or when it is. Or does she? When a large priceless diamond, sounding much like the controlling Grey Emerald, pops up through-out Earth's history she decides to write herself into the past in the hope of getting it back and stopping it falling into the wrong hands. But she's noticed by the world's only consulting detective- Sherlock Holmes.

Chapter One.

High above the planet New Mobius a final battle was taking place. A battle between good and evil, brains and speed. The fight to end all fights between Aleena the Hedgehog and her arch enemy Professor Eggman...

Along the deck of the newly restored Death- Egg, (A space station capable of destroying a whole planet in one go. And also shaped like Eggman's face.) Princess Aleena, dressed for battle in a black bodysuit under a blue mini-dress, shot off along the deck in a blur of black and purple. She skilfully dodged the rockets that came her way and jumped over the huge turrets that were primed to take her out. She only had one shot to stop Eggman's latest plan for world domination, and if she messed up...That was it. Game over.

The lilac heroine blinked the sweat from her green eyes and curled her white gloved fingers around the last of the Chaos Emeralds. The Grey one, the only one not to have been destroyed or lost during the years of war. It was the last ray of hope, of light that could stop this madness. Hurrying along Aleena heard the unmistakeable sound of powerful jet engines and quickly hit the ground, covering her head. She looked up and spotted the hulking mass of metal, guns and...Well, ugliness land a few feet away. Shakily she got to her feet, tucking the gemstone into her pockets for safe keeping.

The Egg-Terrorizer, Eggman's newest toy, stilled just shy of squashing her flat and lowered its massive head to regard her. Eggman grinned through the visor making the robot's shoulders shake as he chuckled. "So, it all comes down to this? You. Me. And a little gemstone." He leaned over the tiny rodent, from his wrist a series of rifles extended and locked onto their target. "You honestly think you can stop me with that lone Emerald? Look around, sweetheart, I own this world. Your friends and family fell to me in a heart-beat, the Chaos Emeralds are mine to control and use as I see fit. Now... Hand it over and I might let you live."

"No."

"What? Speak up, rodent."

Aleena gritted her teeth. "I said...NO!" She jumped into the air, curled into a tight purple ball and headed towards the Professor. At the last possible second, the Egg- Terrorizer vanished in a green shimmer of light. Aleena landed and looked around confused, "What the he-ARGH!" The robot smacked her hard from behind, sending her skidding across the floor. She got up to her knees, her chestnut hair spilling from her ponytail and into her eyes; she pulled a face rubbing the back of her head. "That's...Chaos Control?"

The giant robot wobbled with glee again, "Indeed, girlie. Finally I have mastered the art of teleporting with the magic in the Emeralds. It took five of them to crack the secret, whatever was left over I used on my wonderful creations. Now hand over the last one." Aleena slowly reached into her pockets, with-drawing the stone she shifted from foot to foot, tossing the gem between her palms. Eggman licked his lips, "That's it, just give it to me. GIVE IT TO ME!"

"Not a chance." She smirked, "You'll have to kill me first."

"Fine. Then I will. All weapons, full power!" From every-where thousands of guns lined up and hummed with power, ready to take the hedgehog out. Aleena stood very still; she had to time it just right. Eggman stomped forward, the deck of the Death-Egg shook with each step. He aimed his wrist weapon at Aleena and grinned once more, "So long, hedgehog. FIRE!"

"CHAOS INFERNO!" Aleena shouted at the top of her lungs and held the Emerald in front of her.

What happened next seemed to happen in slow motion. The green beam of highly unstable energy escaped Eggman's wrist. At the same time a silver bubble of protection grew out of the Grey Emerald, it encased Aleena and started crackling when it sensed its brothers and sisters powers. Green hit grey resulting in a spectacular fireworks display, which lit up the whole sky along with a muffled sonic-boom that echoed through-out the deck.

When the dust had settled, Eggman and Aleena were nowhere in sight. All that was left from their last battle were two sets of scorch marks on deck were the two had been standing.

ELSE WHERE...

Aleena fell through the howling abyss of swirling gold and pink, commonly known as The Void, the space between dimensions. She fell with her arms spinning like windmills in a vain attempt to slow her descent.

She made the classic mistake of looking down. Coming up fast was a platform and she realised, in horror, that she was going too fast to lower her chances of not becoming a hedgehog pancake. She slammed her eyes shut as the platform got closer, and closer, and closer...

When she dared to open them again the purple hedgehog found herself lying, flat on her back, at the centre of the floating disc with no broken bones. Rolling onto her belly, she gingerly sat back on her hunches and looked at her surroundings. The vast space of the Void made her shiver, and with good reason: Too many bad memories. Getting to her feet she dusted herself down, quickly made sure her friction- resistant bodysuit wasn't torn, pulled her hair back into its neat ponytail and checked her retro designed red sneakers for damage, before stepping to the disc's edge. She frowned. Something didn't seem right.

"O...K... Now that's not right." To the left of where she was standing there was a big patch of white, as if someone had splashed a whole pot of white paint on the Void's surface. As she peered at it something odd happened, or it was her imagination going wild, but the mark seemed to be getting bigger, and bigger. She stepped back feeling slightly disturbed. "What the hell is going on? Why am I back on the Ghost Roads? And where is the Prof?"

"All will be answered...if you turn around."

Aleena froze. She knew that voice. Knew it better than anybody. But it couldn't be him. Slowly the Princess turned...And saw nothing. There was no-one there. It was only then she became aware of something tugging the hem of her skirt. Glancing down a gasp left her lips as she came face to face with a small, chubby blue hedgehog. The hedgehog smiled-no, he smirked- at her. It was a smirk that she had grown up with all her life.

The Princess knelt down slowly until she was eye level and timidly reached out a shaky hand. The hedgehog grinned into her touch and nuzzled against her hand on his cheek. "Oh, Crystal..." she breathed. "It's you, isn't it?" The hedgehog nodded making her sob, "I thought I'd never see you again!" She leaned closer and wrapped the little hedgehog in her arms, crying into his neck. "I've missed you so much!"

The tiny hedgehog made soothing noises and rubbed her back calmingly. "It's OK, Na-Na. Daddy's here now." Holding her back by the shoulders he wiped her tears away with his thumbs. He looked her over and his smile grew. "You've grown, Aleena."

She grinned cheekily, "So have you. Downwards, and-judging by the retro look-somewhere near the start of your career. Before the accident with the-" Her father scowled at her. "OK, zipping it." She stood and dusted herself down a second time. "Right. Last thing I remember is fighting Eggman and using the Grey Emerald. I'm guessing you have reasons for dragging me here. So... Classic Sonic, let's hear 'em."

Little Sonic (or Classic) folded his arms, "The white-wash effect you see is the work of an unknown enemy. Their plan is to wipe out my past and future in every reality. In an attempt to slow it down every version of an older, or Modern, Sonic is being teamed-up with a younger, or Classic, version-Me. Because of the untimely death of the Modern Sonic of your world, you were sent here instead; fortunately the Emerald sensed the danger and used Chaos Control instead of Chaos Inferno. For the last question: Where's the Prof? He's in the same place as the Grey Emerald which you need in order to restore my-and in turn-our legacy." He rubbed the back of his neck. "It's so confusing even I don't understand some of it."

Aleena folded her arms and paced back and forth. "So...I need to jump realms, steal the Emerald back, avoid the local police, defeat Eggman and restore a part of our time-line. Right?" Sonic nodded. She grinned widely. "Well it's easier than the stuff with the Anarchy Key and I'm cool with that. Let's do it!"

The earlier version of her dad regarded her with narrowed eyes. Seeing that she was dead serious he nodded and grabbed her hand, pulling her swiftly behind him. "Let's do it to it, Princess!" Running at full speed the two headed for the disc's edge. Aleena tugged Sonic's hands nervously but he squeezed it reassuringly. "Get ready to jump!"

Together the unlikely duo jumped into the vast space. They used the glowing orbs, which Aleena learned were hubs to the other dimensions, to bounce across. Soon they stopped at another platform where an orb sat on its own. This one was glowing slightly brighter than the others. Classic Sonic touched its' surface and it shimmered.

"Here we are. Both the Emerald and the Prof made it to this realm." From inside the orb Aleena could hear the everyday sounds of life: the honking of cars, people chatting etc. She looked at Classic with slight concern. "Don't look like that. If you don't believe me…"

Aleena leaned forward. The orb shimmered again and this time she could faintly make out a huge, bulky shape in the fog. She stepped back and folded her arms. "That's the Prof, alright. That's his Egg Terrorizer. But something seems off about the time. When is he?"

Classic pursed his lips, "I think he's in this Earth's past. I think…He's writing himself into Earth's history. Every time the Chaos Emerald is re-discovered he shows up to try and steal it. And every time he fails because something is always preventing him."

"Oh, yeah? What?" She asked teasingly. Classic looked back dryly. She blinked, "Oh, me!" A grin. "Well, obviously me."

"And there's the classic big-headed attitude coming out." Her dad muttered with a head shake. "Now, we need a plan. If we use your choker, that's impregnated with your Master Emerald, we can also pop up in and out Earth's history the same time as Eggman or the Grey Emerald, which they've called, Pierre de Mort, which seems fitting considering the back-story they've cooked up." He shook his head again. "Silly humans."

"Uh, dad…" Aleena pointed at the orb. It was glowing with a red lighting effect. "What's going on?"

"Oh, no! No, no, no! Eggman's jumped again. Quick, Aleena, we need to act super-fast in order to keep up. Use the Master Emerald to active Chaos Control and follow him."

"Are you nuts? Your great plan is to write ourselves into the past, follow Eggman and stop him from stealing the Chaos Emerald so that we can steal it?"

Classic nodded, pulled out a sleek object from his quills and handed to her. "I can't go with you in body, I have to stay here and keep an eye on things, but I can in spirit. I've programmed this—I think they call it an I-Pod, but I've renamed it an S-Pod—with a holographic version of myself. When-ever you need me, use this. If you can't get a hold of me, text me."

She nodded. "OK." She thought for a second and then, "Hold on. If I go jumping along the time-lines as well I'm bound to be noticed."

"Yes." Her dad's reply was drawn out as Ye-ss.

She huffed. "What I mean is, I can't just rush in—like you. I need a disguise, something that won't be too obvious in case I am noticed."

Classic sighed loudly, "Just like your mum. Fine then, here's your disguise." From his quills again he pulled out a lump of cloth. Aleena slipped it on and tugged it down so every inch of her was covered. "Ready now?"

A nod, "I'm ready. But there's just one last question."

"Only the one?"

Aleena arched a brow, "When I get the Emerald back it will low on power, right?" Classic gave a slow nod. "Well," she jerked her head towards the portal, "seeing how primitive their technology is and how they love war and blood-shed, how am I going to solve the impossible task of powering the Emerald with feelings of love and friendship in such a dreadful place?"

Classic slowly grinned, "You've hit the nail right on the head!" The mini version of her dad plunged his hand into the heart of the glowing orb. "Wait. Wait. There he is! The man who loves to solve the impossible." He stepped to the side; Aleena leaned closer and stared into the orbs centre.

She blinked in surprise and asked. "Who is he?" The man in the reflection had a short mop of lightly curled ebony. He had a very pale complexion, was tall and slim and looking pretty foxy. He was wearing a long black, woollen over-coat over a fitted dark suit, and a navy blue scarf wrapped around his neck. But it wasn't any of these things that captured the young Princess. It was his eyes. They were ice-blue and shone with a fierce intellect. Her breath caught in her throat and her heart thudded against her ribs as she stared into those blue eyes. When he smirked he gave the impression that only he knew the answers to the world's deepest, darkest secrets. "Who is he?" She whispered again, a light blush growing on her cheeks.

Classic spotted her reaction and smirked to himself. "His name is Sherlock Holmes. And from this moment on he's also your new best friend."

It's good to be writing for the Sonic-verse again. I've missed it.

Now, about the story. The white-washing of the Void is a similar opening scene to the one of SONIC GENERATIONS. (Hope you don't mind.)

I have drafted more chapters, but apart from the main plot and that it is going to be slightly OC/ Sherlock, I have NO idea where I'm going with this.

However, if I DO stray and start becoming Sonic06 in any way, you are free to flame me. But any feedback is welcome.
