Ending #2: Bittersweet Ending

Tegan could only watch as the warlord swiped at Wheeljack, clawed digits grazing his grandmother where she stood in the wrecker's servo, sending her flying as the white, red and green mech attempted to catch her.

Only able to stand stock still as he watched, unsure on how he should get involved, Tegan stood rooted to the spot as he contemplated… Earth didn't matter to him, didn't it? His mother's kind had treated him like an animal for as long as he could remember, and there was nothing worth fighting for there… Or was there?

How his comm. Link had been hacked, Tegan had no idea… Only that Miko was suddenly talking to him. ::Teeg? Teeg I-I'm so sorry for lying to you… But you need to help us. If you don't, we'll all be destroyed! Megatron's only using you to get what he wants!::

Freezing up at the voice of the Japanese girl, Tegan felt relief fill him despite the situation. He hadn't actually killed the girl he had come to love. ::Miko… I'm so sorry… But… Megatron's right. Earth has never treated me like I was a person like them. Only as an animal.:: He responded firmly, though his tone wavered a little.

Silence fell for several moments before Miko spoke again, voice gentle and soft. ::Tegan… I treated you like an equal… Even though I knew you were part Cybertronian.:: She answered before continuing on in an even quieter tone. ::Tegan… I care about you. That's why I brought you to the Autobots, because I wanted you to be safe… You're all I have left. The Omega Lock was targeting Japan… My parents and the rest of my family are gone.::

Hearing the crack in Miko's voice, the way her usually loud and boisterous way of talking was absent, Tegan felt something break inside of him… Megatron had destroyed Japan? That meant that Miko's whole life was gone! The realization of what the Omega Lock was truly doing to Earth, his mother's world, and what Megatron really wanted struck the young mech hard.

Growling lowly and cutting off the comm, Tegan charging the warlord who noticed the movement and ducked under Optimus' attack, bringing his fist in an uppercut, the enraged black and green techno organic sent flying across the expanse.

Tegan cried out as he landed again… Everything was so confusing. Megatron had lied to him, had only been using him, and now the entirety of his decisions had fallen upon him… He had partly been involved in destroying everything Miko loved and cared about! It was because of him that millions of lives were being destroyed and lost at this very moment… But he could still save some of them.

Snarling in rage, Tegan forced himself back up to his pedes, activating his tires as he sped around the expanse of the lock, making his way back up to where Shockwave was defending the controls of the Omega Lock.

Tegan crossed the distance rapidly, Shockwave saw his experiment approaching and brought his cannon around, firing at the pedes of the charging mech, who jumped over the blast and flipped over him to land directly on the controls.

Smirking as Shockwave turned around, Tegan slammed a servo down on the cancellation button, cancelling the firing sequence in time before Shockwave grabbed him by a shoulder strut, jerking him away. The force of the pull and his own body weight behind it, Tegan screamed when it was ripped loose of his own frame.

Landing hard and rolling onto his side, Tegan groaned in pain, the steel flooring beneath him hissing from the Tox-N slowly leaking out of his wounded shoulder.

"Lord Megatron should've authorized a self-destruction sequence. It would have been logical as of this moment." The scientist stated as he approached, canon pressed against the younger Decepticon's helm, Tegan shutting his optics and waiting for the shot that would take his spark.

"TEGAN!"

The call was unexpected, and jerked Tegan from his quiet submittance to death, optics shooting open and falling on a familiar figure, standing a little away from him, beautiful brown eyes wide as she stared. "Tegan no!" Miko cried, looking both frightened as well as upset.

Optics locked with brown eyes and Tegan gave a sad little smile, turning his faceplates away and shutting his optics as he waited for the shot that would take his life. When it didn't come, gree optics opened and he looked up in surprise at Bulkhead, who looked down at him before charging at Shockwave again, the scientist getting back to his pedes.

Taking the chance, Tegan pushed off the ground and scooped up Miko, rushing her over to one of the cylinders filled with the synthetic energon, setting her down. "Stay here Miko." He ordered her before he turned and charged to where Optimus and Megatron were fighting, kicking off the ground and placing both of his pedes against Megatron's shoulders. The momentum as well as his sudden weight caused the warlord to stumble, a snarl forming on the scarred faceplating as Optimus took the advantage, attack gaining speed and precision.

Megatron was forced back by the Autobot, the massive Kaonian warrior having difficulty in keeping his balance on the small expanse of ground that was the edge of the Omega lock.

The young techno-organic shook with rage and bitter hatred as he battling his way back up onto his pedes, optics locked on the sight of Megatron standing at the edge of the Lock, Optimus hanging on to keep from falling to the distant planet below.

Keeping his optics firmly set on the silver warlord, Tegan began to move, slowly at first, but quickly gaining speed until he was in an all out run, slamming his shoulder into Megatron's side and sending them both tumbling.

Megatron grunted under the impact servos scrambling for something to grab onto and keep him from tipping over the edge, servos finally locating Tegan just as he fell, the smaller mech's digits scraping against the ground and leaving small stripes of paint as the warlord's weight dragged him along to the edge.

Grasping tightly to the edge of the lock, Tegan looked sidelong at Optimus Prime, the massive Autobot warrior struggling to get himself back up and onto the deck.

"If I offline, I'm bringing you with me, Paradox!" Megatron snarled from below, Tegan looking down at him and baring his own denta. His arms shook with the exertion of holding both his and Megatron's weight, and he felt sharp stabs of pain as wiring began to snap in his left hip joint.

Tegan whimpered in pain as Megatron's taloned digits dug into his leg, easily piercing the metal as he attempted to climb up the smaller Decepticon's frame. "You keep that up, I'll let go." Tegan threatened, the Kaonian gladiator laughing, the sound cold as it sent chills down the black and green mech's backstrut. Megatron seemed unbothered by the Tox-N infused energon running over his servos, a sizzling sound filling the air between them as it ate away at the thick armouring like a starving scraplet.

Glancing back up the lock where Optimus was just climbing back onto the deck, Tegan looked back down at Megatron, frowning deeply. If the warlord wasn't flying or transforming, he had either suffered internal damage fighting with Prime, or Tegan's first attack had done more damage than he had initially thought.

Feeling his digits slipping, Tegan ground his denta together, optics tightly shuttered as he kicked at the Warlord with his free pede, desperate to free himself.

Clenching his denta and muttering a wordless apology, Tegan's digits slid from their hold, the lithe mech falling into space, Megatron's angry roar ringing in his audios when something caught him by his arm. The jolt caused a cry of pain to come from between his lips as Megatron, retaining his grip, tore plating and wiring from Tegan's lower leg.

Tegan opened his optics to watch Megatron fall, the pain in his leg numbing, but he didn't dare look at the damage. Looking up, his optics locked with Optimus Prime's, the Autobot leader carefully lifting him up and onto the deck where Tegan collapsed onto his side and shook violently.

Miko was there in moments, hugging the side of his faceplates and crying, Ratchet only moments behind, but the black and green cybertronian pushed the medic away and struggled up to his good pede, carefully making his way towards where Soundwave lay in a pool of luminescent blue.

Dropping down next to the TIC, Tegan vented shakily as his optics roamed the frame of the mech that had changed his life, plating nearly rattling with the threat of sobbing… Soundwave couldn't have offlined so quickly could he?

As if in answer, the visor lit up dimly with a smily emoji present on the clear glass, Tegan letting out a tiny laugh. "S-Soundwave… My... My body…?" He asked shakily, hope expressed on his faceplates.

There was silence as Soundwave seemed to be struggling to form the words. "Gone… Megatron, destroyed Tegan's old frame." The telepath finally managed, servos still clasped firmly over the wound in his chassis, a black and green one joining it as Tegan looked down at his mentor, not wanting to cry, but he could feel the lubricants gathering in his optics. "I'm… Sorry, Soundwave… I failed… This is all my fault."

Lithe digits reached up to touch the white faceplates, and Tegan looked into the visor as he leaned into the touch. "Tegan, did well. Tegan, not at fault." Soundwave responded in a calm tone, thumb digit gently caressing the faceplating of his young ward, and he'd have smiled if he'd been able to. "Soundwave, proud." The telepath murmured in a soft tone, unfamiliar to Tegan until he realized it was Soundwave's true voice.

Lower lip trembling, Tegan felt the tears leave his optics now as he gripped Soundwave's wrist. "I'm sorry Soundwave… I'm so so sorry." He whispered, leaning his helm against the lithe Decepticon's mid abdomen, optics shut tightly as he sobbed, Miko coming up to place a hand on the back of his servo.

"Teeg?" Miko asked gently. "It's alright, Teeg. We'll see him in the allspark one day."

Tegan glanced at the human with tears falling down his faceplates. "We?" He asked softly, voice slightly hoarse.

"Are you sure you want to try this?" Arcee asked from where she stood, arms crossed over her chassis and a skeptical look on her faceplates, optics directed towards Ratchet, Miko and Tegan, standing at the edge of the Omega Lock's cybermatter.

"I want to try." Miko responded, looking up at the two-wheeler, then Tegan and Bulkhead, standing side by side. "It'll work." She added, as if to reassure the two titans with a smile. "Besides… I've got nothing to lose if it doesn't work… My family and country are gone." The youth answered.

Ratchet knelt on one knee joint next to the cybermatter, expression grave. "While it is risky, there is a high chance of thise working." He stated, glancing up at Arcee, who still looked skeptical, then over at Optimus and the others, the Prime giving a small nod. "It is Miko's choice alone."

Miko took a deep breath and moved closer to the cybermatter. "I want to try." She repeated, removing her shoes and glancing around again before sitting on the edge of the decking and slowly lowering herself into it.

Tegan went to move forwards, spark whirling around with worry, but Buklhead grabbed his arm. "Easy, kid. Let her go." The wrecker advised before releasing the smaller mech's arm, Tegan remaining in place this time, though his optics were over-bright with worry.

Everyone stood in a half circle before the cybermatter, the surface rippling gently from the submergence of the small human form.

Staring deep into the nearly clear substance of the matter, Tegan squinted as he noticed a soft glow begin to emanate from deep within the cybermatter, causing him to jostle Ratchet with his shoulder and point.

Ratchet grunted and opened his mouth to reprimand the young mech at his side when he noticed the green optics locked on the pool before them and pointing, drawing his attention to the soft glow beneath the rippling surface. "By the allspark." He murmured, crouching on the edge of the decking as he watched the strange light slowly gain brightness.

Tegan felt hopeful at Ratchet's surprised exclamation, optics widening when a servo shot out of the surface of the cybermatter, grasping the edge of the decking, Ratchet jerking back in surprise while Tegan's full focus was on the servo… It was delicate looking, the digits long and thin… Femmelike. "Miko?" He murmured as a pink and black helm broke the surface. "MIKO!" He cried, rushing to help the cyberformed girl from the matter.

A lithe black femme crawled from the sticky liquid, ice blue optics wide and perfectly shaped lips parted as she gasped for air, seeming to struggle in doing so, panicking Tegan. "Miko? Miko!" He cried, Ratchet holding up a servo. "Give her a moment. She's trying to figure out how to cycle it through her vents… Imagine it like a sparkling trying to take it's first breath." The medic advised.

Tegan remained tense until the moment when Miko finally began to vent, air expelling cybermatter clinging to her vents with a soft whoosh, allowing the green and black mech to relax. "Miko?" He asked again, the gorgeous young femme looking up at him with a grin. "Told ya it'd work." Miko stated, Tegan mirroring the gesture for a moment before it faded and he looked away. So much had been lost today…

Standing up as the other bots moved in to talk to Miko, Ratchet shooing them away so he could examine her and make sure there was no difficulties, Tegan wandered away. He moved to the very edge of the deck to stare down at Earth, the once blue and green planet now grey and white, with the tiniest blips of green and blue still visible mottling it's surface. Earth had been lost, and, with it, billions of human beings.

Glancing over his shoulder, Tegan felt the lubricant gather in his optics again when his optics passed over Soundwave's dull, greyed frame, his grandmother, carefully set atop a console, faceplates so serenely peaceful that Tegan could've sworn she was sleeping had Wheeljack not quietly confirmed her death to him before Miko entered the Cybermatter.

Looking down at the ground, Tegan shut his optics tightly and tried to control his sobs as he felt a small servo slip into his own, the young mech clinging tightly to it, optics opening to look at Miko. "It's alright Teeg… You and me, we still have each other, right?" Miko murmured gently, Tegan smiling faintly and squeezing her servo gently before looking back out over earth… He knew he couldn't do this alone… But he wasn't alone was he?

He had Miko.

((A/N: So that's that. The end. :D I might redo some of the chapters later since I didn't like some parts. But if it happens, it happens. If not then lol. I'll leave it up to you if Miko and Tegan actually get together later on in life, but due to the infusion of Tox-N, it is unlikely the two would be able to do much more than what they've currently done. Even kissing might transmit the toxin to Miko. Anyways. Here's pictures for what Miko looks like:
