Second part of Dr Who and Sonic the Hedgehog crossover. (1st part was Rise of the Egg knights.)

Lay out might seem a bit fiddly, that's thanks to me fudging up prologue. So right to it.

Dr Who and Sonic belong to the BBC and SEGA respectively.

Anyway, enjoy!

Age of Nazanity.

Full Summery

Part 2 of 2. Eggman and Celosia are one fourth of the way to awakening the beast known as the Nazo Serpent. There is, however, a small ray of hope as the Doctor and the Freedom Fighters give chase.

Chapter 1.

One week earlier ( ish.)…

The unexplored part of the 7th galaxy was very quiet, well it was until the darkness was ripped opened with a bang! From the Time Vortex's sparkling depths a box shaped object shot out at alarming speeds. A second later the gap widened and another shape appeared, bigger and more deadlier than the box—an intergalactic war ship.

The TARDIS zigzagged amongst the stars wildly, trying to avoid the laser blasts from the battle ship that was gaining on it fast. The double doors of the box flew open and a black hedgehog in a red space suit climbed onto its roof. From his back pocket the hedgehog pulled out a small laser pistol, took aim and smirked.

"Oh, yeah!" Someone laughed behind him. Glancing over his shoulder he saw a black tuxedoed cat grinning at him. "Time to kick some Robo-butt!"

" You should be resting."

" What! And miss the party? No chance!"

He sighed. "Fine. Just don't get in my way, So—Hey! Hands!"

She looked up at him from her crouching position with a scowl on her face. She showed him a couple of thick wires in her white paws and finished hooking up his harness before starting on her own. " Safety first. You know what he's like." She nodded at the blinking lamp on the TARDIS' roof. " Thinks he's king of the Time Vor-heck!" The TARDIS jerked sharply, Shadow reached out and grabbed her hand before she went flying. He held her steady as she tightened her straps. " Thanks." Shadow didn't release her, he just gazed at her. She tapped his arm, " You can let me go now."

"Oh, right." He looked at his gun for a second, his smirk returning and growing. He handed it to her, "You know how work this, right?" he asked and then clenched his fists into tight balls, a second later his hands bursts into blazing pink flames. He hummed with quiet approval, " Ready, Sola?"

She returned his smirk, flicking off the safety on his gun in a well rehearsed move. "You bet. Let's do it to it." Standing side by side, the two friends returned fire.

Inside the TARDIS, at the heart of the vast control room, a mushroomed shaped console stood with many blinking lights, switches and knobs. The glass pillar standing on its top glowed and dimmed, bathing the area in an eerie green glow, as the time rotor inside rose and fell in a steady rhythm.

Working frantically at the controls a skinny man with brown hair frowned as he tried to nudge a troublesome switch into submission. " C'mon, old girl," he said softly to his beloved machine, " now's not the time to be stubborn."

"Doctor!" cried Tails, an orange two- tailed fox, from the other side of the table. "I got flashing lights over here!"

" Me too!" yelled Rouge, a gorgeous white bat beside him. "What do we do?"

The Doctor grunted still trying to fix the switch, "Hold down on your levers, and whatever you do, don't let go. Amy!"

Amy Rose, a cute pink hedgehog , looked at him over her shoulder by her place by the door. "Yeah?"

"Get those trigger-happy morons inside. Mercy will be coming up any second and if we miss it again…" he reached down, grabbed the mallet he kept for troublesome switches, and gave the console a thwack. The switch finally flipped over. " Finally! Now, where was I?"

" Trigger-happy morons."

"Thank you, Rouge. If we miss it again there'll be a double murder."

"They're not responding." She tapped her ear piece, " Sounds like Sola's having too much fun."

"Oh, for the love of…" The Doctor stormed over to the opened doors, took hold of the two safety lines tied on the hand rail and gave them a swift yank. Above them the group heard twins grunts, growing rolling thuds and then,

"Whoa!"

"Ugh!"

Shadow and Sola fell through the doors, landing with a bump at the Doctor's feet. Simultaneously they looked up and grinned sheepishly at him. At his deepening frown they sighed and looked away knowing they weren't going to win this round.

" We've been chasing Mercy for 57 hours and have missed it 9 times. We've jumped 18 different times tracks and for the last 11 hours have been fired at, repeatedly, by Eggman. Now, if you two boobs have quite finished…" He pointed purposely towards the console. The two animals got the message and scrambled up the ramp. He closed the doors, leaned against them and rubbed the bridge of his nose.

Amy unclipped the lines and put them back the trunk in the corner. Seeing the Doctor looking very tired she patted his arm gently. " You did good. Sometimes they need a firm hand, especially Sonic."

He gave her a weak chuckle, " How did you cope for so long?"

Taking his hand, she led him up the ramp and smiled, " With a lot of patience and a large plate of choc-chip cookies."

"Sounds great."

Her smile grew, "I'll see what I can do, after you park the TARDIS safely."

He returned her smile, " Yes, ma'am," winked and dashed back to his place. A few adjustments later and the pitch of the wheezing engines of the time machine rose in timbre. " Next stop, Mercentoras!" Whooping joyously, he grinned at the Freedom Fighter's excited faces, slammed down a final lever and gripped the console's edge as the TARDIS screamed towards a pink and orange planet in the distance.


The place was old. Old and dusty. A fine layer of dust coated the floor and surrounding surfaces. Tiny weeds struggled through the cracks in the floor tiles and thick vines draped from the ceilings. Old machinery, computers and the like, sat rusty, alone and forgotten.

It was deadly quiet, until a sudden howling wind, sounding like a group of drunk trumpeting elephants, reverberated around the room. A second later the TARDIS forced it self into existence, kicking up the dust and depositing it somewhere else.

The doors opened and Rouge, in a short summer dress and ankle boots, popped her head out. She wrinkled her nose at the stale scent, quickly ducked back inside and walked out carrying a long woolly cardigan. "This it?" she asked, slipping the cardi over her shoulders and buttoned it up with a shiver. "Place is cold." She ran a finger along the nearest surface, frowning as her white gloves were now covered in dust. " And dusty. Just great." She shook her head, muttering and clapping her hands clean.

"Wow! A real different planet!" Tails, wrapping a thick scarf around his neck, looked around. The dust covered his new red Converse trainers making him scowl, "Just cleaned these…" He muttered as he joined Rouge.

Amy was next, practically skipping out of the TARDIS. She had the hood of her bulky red jumper up and smoothed down her mini-skirt . She gasped, pulled out her camera and span on the spot taking as many pictures as she could. "OH. MY. GOSH! Shadow ,you must see this!" Pocketing the camera, she lunged into the open doors and pulled. " Come on, you'll miss it!"

The black hedgehog sighed as he pulled from the box. His red eyes scanned the area." Just as I remember it. Cold, dank and full of books." He was now wearing a jacket over his space suit, as he zipped up he sniffed. "Smells the same too."

"Will you get a shift on?" came a voice behind him, "I want to see too, you know." He was propelled forward by a sharp shove. Sola, just finishing pulling her long hair into a single braid, winked cheekily at him. Slipping on her favourite blue waistcoat she paused to polish and admire her new robotic right leg, that once belonged to Metal Sonic, and turned to face the Doctor. "You coming, or what?" she called.

Looking up from the controls he nodded, "Just a tick… Ah-ha, got it! Try getting away from me now, old girl." Locking down the controls, incase the TARDIS decided to jump time tracks and leave them stranded, he plucked the fully charged sonic screwdriver from its slot and walked down the ramp, throwing his long brown coat over his shoulders. He stopped just inside the doorway and suddenly started smoothing down every wrinkle he could find on his blue suit. "Do I look OK?" Next, he bent and retied the laces of his burgundy canvas boots, " First impressions are always important."

The cat sighed, "Are you always like this?"

He straightened, guided her out and locked the doors with a flourish. He took her hand, "Not all the time." He grinned wildly, "Here we go ,then. Whole new world. Are you ready?"

She shook her head laughing, "No."

" Neither am I. Isn't it great!" They hurried over to where the others were gathered around a very rusty computer. "Right, then. Let's have a quick look." Working fast, and with the aid of a short blast of sonic energy, he brought up the schematics and whistled. " Here we are. Get a butcher's at that." He moved to the side and let the Freedom Fighters see the mysterious Mercy for the first time. The planet was the same size as Earth Prime, had the same marble effect only it was pink and orange instead of green and blue. The planet also had the same white spots on its top and bottom for its frozen Poles. But the thing that really surprised them were the thick chains that extended from the snowy points, into the sky, anchoring twins moons in a steady orbit. The Doctor fiddled with the controls and zoomed in on the moon fixed in place via Mercy's North Pole. " We're here. Second moon, home of the Lost Library. How's it feel to be back, Shadow?"

Shadow shrugged, "The same, Doctor." He looked around, hardly believing his eyes. " I still can't work out how you did it."

"Well… That's easy. Every time Mercy disappears it leaves behind tiny traces of a certain kind of radiation. Having been here before, Shadow, you have been contaminated with the same stuff. Judging by your face you don't believe me. Here," Handing him his 3D glasses, the Doctor had to smirk as Shadow put them on, lifted his hand and blink. "See? Your Chaos Aura—normally golden in colour—has been contaminated." Taking back the glasses he stuffed them in a pocket. "Taking a sample and using the Chaos Emerald to boost the TARDIS' scanners, we find ourselves here."

" Yeah," said Rouge pointing to another screen that had struggled to come on line, "and so did they."

The group huddled around the monitor, the Freedom Fighter's faces quickly wore looks of discomfort as the shapes came closer. New and improved, the band of metal men in black marched on with a purpose. Each one had eyes of a blazing blue and bulky head phones studded with twinkling red lights. A golden E was branded on their chest plates.

The Doctor murmured softly to himself. " The Egg Knights cometh."

R and R if you like, you don't have to but it would be nice.
