Beats till the song disappears

......

Classic era, Sonic 2's bad ending timeline but I made it better. Or worse. Leaving for you to decide. Enjoy :)

...........

He trudged through the dark zone, silent and windless akin to a closed, lifeless chamber.

The place was littered with systematically arranged crystal blocks that would've looked aesthetically pleasing if it were daytime. For now, they just made the place more eerie as he waited for Robotnik to show up.

After what felt like an eternity of worried pacing to the speedy hedgehog but in reality was barely a couple of minutes, two of the structures nearby split apart, revealing a camouflaged panel sliding in the ground.

Sonic stopped, facing the opening to see the Eggmobile rise from the underground, hovering a meter or so above the inclined floor leading into the depth.

The doctor looked composed, unworried, his spectacles glinting with a previously absent touch of confidence, of victory.

"Did you bring them?" He asked, addressing the frustrated hedgehog.

Sonic revealed four emeralds without a word, pulling them away as the other tried to grab for them.

"Tails?"

"Hand them over first."

Sonic was about to retaliate but paused at seeing the other hover a finger over the mobile's control panel, staring straight at him with the unspoken threat clear in his body language. He could kill the kit if Sonic wasn't careful.

His thoughts conflicting with one another and the concern for his little brother chiming in, he finally relented, holding out the gems for the mobile's claws to grab.

"Now tell me where he is."

"Careful, hedgehog, you don't get to make demands here. I believe we had an agreement that he'll be spared only if you brought all five Chaos Emeralds, hmm?"

Silence fell over the terrain, the hero shooting a venomous glare at Robotnik. It would be too much of a gamble to attack him when he had a link open to wherever he was keeping Tails. His lack of acknowledgement to the earlier question was answer enough. He hadn't been able to collect the required number of emeralds on time.

"I see," the scientist murmured.

Sonic gritted his teeth, high strung, on edge. He was aware he had failed but he needed to know...

"Just tell me if my brother is alright."

"He is," the other sighed in an exaggerated display of disappointment, "I would've gotten rid of him by now provided your ineptitude-"

"You know I can't locate them all this fast!" Sonic snarled, looking seconds away from jumping at his throat.

"But I am feeling rather... merciful today," the man continued on without even reacting to the interruption, his demeanor betraying he held all the cards. "I propose another deal, hedgehog. If you agree, I promise that no harm will come to Tails."

Sonic shouldn't trust him. Didn't trust him. But if it meant Tails would be safe...

He nodded, signalling to Robotnik that he was listening. Said scientist smirked under his mustache.

"Become part of my legion. Surrender yourself to me, and your little friend will go unharmed."

His legion. The hero had fought against him enough times, had seen enough horrors and rescued enough critters being used as test subjects to read between the lines, to know what Robotnik meant. The mere mention of that thing still makes him sick. Robotnik wasn't asking him to just give up his freedom. He was demanding for Sonic to give up his mind and body, his free will, in the worst way possible.

Sonic's life or Tails' safety?

It took him less than a second to choose.

"Well?" Robotnik's voice prompted, already knowing his nemesis' decision.

"If you hurt Tails-"

"Oh don't be so leery. I gave you my word. Your fox friend will not be harmed. Now, do we have a deal or do I signal my bots to neutralize that menace?"

Sonic squeezed his eyes shut, shaking with a plethora of emotions he couldn't bring himself to grasp and process as they came and went in waves. He gasped in a breath and stilled, before coiled tension leaked away from his body and he sighed. Surrendered.

"Deal."

"Excellent!" He could hear the victorious grin in Robotnik's voice but he didn't react, unable to bring himself to look up, gaze fixed on his red and white sneakers as he willingly sealed his fate. His iconic shoes held his focus, shoes that allowed him his freedom to run as fast as his heart desired. The same freedom which he was now volunterily giving up for his brother.

It felt like just yesterday when he had met the little guy, his shoes very smilar to Sonic's own, a matching color scheme. Something he had never paid attention to before but was now a glaring memory. He hadn't even told Tails how much he cared for him, how much proud he was, had he?

If he were to be given a chance to speak with Tails, he'd never remain silent again.

His feet moved without his consent, following the rotound man into the underground base until he blinked out of his thoughts and found himelf in a lab, facing a tall glass cylinder strung up in the center of the circular space.

It stood empty, it's front open, waiting to be occupied. Sonic stared on, unable to look away.

"Now don't be shy, step into the capsule. Chop chop!"

A hair's breath pause and he stepped forward, inside the glass confinement and upon the platform inside, fully resigning himself to what he had agreed on. His breath shuddered with anguish and dread as Robotnik moved around it to the front and pressed a switch.

The glass sealed behind him with a decisive click.

Adrenaline shot through his veins as the machine hummed to life, lights glowing awake below the platform he stood on and the welded hatch above him.

His heartbeat began to thunder in his ears, quills pricking up but he held still, letting the titanium clamps reaching for him seal around his ankles and wrists.

He saw Robotnik clicking away at a nearby screen and then he felt a subtle jerk, the machine's hum increasing in volume and intensity, the platform under him rising up.

With one final click at the keyboard, sleek contraptions that looked suspiciously like a sci-fi mixture of scanner and blaster surrounded him and pulsing rays shot out from their openings.

Sonic grunted as he felt the energy strike him, the clamps keeping him still.

2%

It started from below, at the legs. Of course it fucking did. Sonic wanted to scream, wanted to yell and kick and bang his fists against the glass, feeling cold numbness slowly spreading up his most powerful weapons, his legs, his speed, stripped from him painstakingly slowly as flesh turned to metal.

All he did was clench his fists and grit his teeth in anguish, his whole being screaming at him to move but he held still. He couldn't move, not if it placed his first friend, his best friend, at risk.

28%

The titanium bands securing his ankles and wrists seemed to tighten, restricting the little bit of movement he had as the rays slowly climbed up to his torso, inches below his heart.

He didn't let the tears show.

For Tails for Tails for Tails for Tails

His thoughts chanted like a mantra, placing all his being into not moving, letting himself be turned into a machine, until his ears swivelled at the swoosh of a panelled door sliding open, urging him to look up.

His breath caught in his throat, each cell freezing up in a mixture of shock, rage and despair.

No. No no no no no no no no NO!

"TAILS!" The anguished wail left his chest just as his heart stopped beating, an engine's hum replacing its frantic rhythm.

He payed it no mind. It didn't matter when it was ripped to shreds anyway the moment his blurry gaze met his brother's.

Glowing red optics stared back.

He tried to move, tried to break free but it made no difference, half his body frozen on the spot, under the control of the Chaos forsaken monster who did this.

65%

The bands on his wrists burned, something warm and damp flowed down his palms and dripped from his fingers. Sonic was numb to it, struggling and shaking in the glass confine, his own screams becoming muffled to his ears.

"You promised! YOU FUCKING PROMISED YOU WOULDN'T HURT HIM!"

A screen beeped, the vitals' charts on it going haywire as the progress bar reached 78%.

The mustached scientist just stood there grinning, unconcerned and victorious.

"And I kept my promise. He is unharmed, well and alive." The words seemed to echo in his head, reverberating as if imprinting on the walls of his mind, the machine's buzz and hum drowned out by them. "Just as you asked, rodent."

He couldn't take his pained eyes off of the small yellow robot and his captor noticed that, turning to address Tails with a deceptively encouraging smile.

"Isn't that right, Metal Tails?"

The little robot finally moved, startled beeps escaping it as it's mechanical gaze shifted away from hyperfocusing on Sonic and towards what it's systems told it to be it's creator.

The familiar innocence in that small gesture, even though seeing it on a roboticized mecha, broke something in Sonic.

He tried to call out to his brother but realized he couldn't speak. He couldn't feel his muzzle or mouth anymore. Oh...

The screen read 96%.

As the metal climbed up his quills and ears and the world began to fade into static, Sonic drowned out Eggman's smug grin and droning of the roboticizer's rays, putting all that was left of his mind and strenght into focusing on Tails.

He wanted his last memory to be of his brother, even if no longer flesh and blood but mere metal and wires, he was still Tails. His Tails. That much was clear from its demeanor alone, the innocence, the curiosity, the intelligence, it was all there. Sonic would be able to tell his kid apart from a thousand other Tailses if he had to.

The tears he'd been holding back finally slipped down, the last piece of his humanity used into conveying to Tails that he was sorry, that he loved him.

99%

His eyes closed, the metal covered up the last of the organic cells and Sonic finally went still.

............

Metal Tails gazed upon the powering down capsule, his processors showing the progress bar having reached 100%.

He couldn't take his focus off of the inactive hedgehog; organic, mechanical, irrelevant, Metal Tails was drawn to him even before the roboticization was completed.

Something suspiciously illogical was recorded in his archives during the process. He had sensed what organics refer to as emotions being conveyed to him earlier by the same being. It seemed to be a combination of concern, remorse and affection.

How could he do that without any working signal and communication link to Metal Tails?

The roboticized hedgehog suddenly beeped awake, internal fans whirring as his systems rapid-fire processed the new programming and commands. He jerked within the bonds and stilled again, hanging limp for a long beat.

Metal Sonic lifted his head up, optical processors switching on to reveal glowing red optics staring straight into Metal Tails' own.

It appeared the other robot was finally awake.

Metal Tails couldn't calculate why the organic hedgehog had seemed to know about him but he had felt drawn to the blue being just the same.

Perhaps it was a satisfactory calculation on his creator's part as Metal Tails' tended to get lonely and this arrangement made him most pleased.

Another robot companion made for the perfect promised gift.

No characters were killed in the making of this story, just as I promised :]
