"Goodbye Sideswipe... forever..." Sunstreaker snarled.

Sideswipe tried with all his might to get freed from Sunstreaker's hand trying to get his face away from the swaying snake like tongue, but alas he had no luck. Sunstreaker was too strong.

But a luck of hope came when Sunstreaker moaned in pain as his body moved to the side and let go of Sideswipe, allowing him to cough and breathe again.

Sideswipe looked back, and saw Rainbow Dash stomp on the ground, and stood next to Sideswipe. Sideswipe could also see Rainbow Dash's Autobot suit had some damage like some black marks, as well as scratches, and a part of the head was off, revealing Rainbow's actual head inisde.

Rainbow looked at Sideswipe and offered a hand along with a smile, "Mind if I lend a hand?"

Sideswipe accepted and he got back up on his feet, standing right beside Rainbow Dash. The two of them readied their fists, and they watched as Sunstreaker made a leap into the air, slamming onto the ground, landing back up on his feet.

Sunstreaker's head icily stared back up and snarled, as he readied his talons for battle.

"So you two aligned yourselves together... very well, you will both be annihilated."

Sideswipe and Rainbow made the first charge, heading for Sunstreaker, both wielding their weapons in their hands. The two of them fired them off at Sunstreaker, landing a few holes in his body, but it didn't shoot him down.

Sunstreaker made the next move by performing a roundhouse kick, hitting Rainbow's chest and knocking her down to the ground. Sideswipe striked back by making several punches across Sunstreaker's face, beating him senseless. Sunstreaker moved back from Sideswipe's fist, and began circling around Sideswipe. Sideswipe backed away, and he began circling too. Soon the two of them began going side to side, moving in a circle like fashion, keeping their eyes focused on one another.

"How does it feel to see your best friend hurt?" Sunstreaker asked, with a devious smirk.

Sideswipe snarled in anger, and his eyes glared at Sunstreaker.

"Oh, did I hurt your feelings? I can only imagine how much fury and hatred must be flowing through your blood..." Sunstreaker mocked.

Sideswipe made another attack, making a swipe with his sword across Sunstreaker's chest. Sunstreaker's demonic form just laughed, not looking fazed by the attack.

"Such a huge amount of shame, you couldn't even save your own brother..." Sunstreaker snarled. "But maybe you'd like to join him with the rest of the Shadowbots..."

Sideswipe responded by pulling out his gun and firing multiple shots onto Sunstreaker's chest, screaming at a high pitch in anger. This possessed had gone too far. He had pushed his buttons, he had crossed the line, Sideswipe just had enough. Sideswipe kept his hand on the trigger, firing more and more shots, not holding back.

The final shot went off, and Sunstreaker's body fell to the ground. Sideswipe reloaded another clip into the gun and he aimed it towards Sunstreaker's demonic face. But as he stared down at Sunstreaker, he saw flashes of blue go on and off, appearing in between the purple glows in the eyes. Could he be? Was he?

"Kill me.... please..." Sunstreaker moaned in pain.

Sideswipe was shocked. Sunstreaker was regaining his consciousness? But he couldn't kill him, not his own brother, not someone he lost a long time ago that gave him great pain.

"I... I can't!"

"P-please... kill me... I can't take this anymore. The darkness inside has consumed me enough... I wish to be one with the Allspark..." Sunstreaker moaned.

Sideswipe slowly backed away, "But I can't. I can't shoot my only brother! Do you know how much pain I suffered when you died? I can't kill you! I just--"

Sunstreaker interrupted by groaning more and more in pain. The nasty purple glow returned back into Sunstreaker's eyes and he fired a blast at Sideswipe's chest, knocking him to the ground. Sideswipe wheezed and groaned from the pain of the blast, it hit him right in the heart, and steam billowed from it.

The host Shadowbot got back up on his feet, and wiped away the purple fluid that had drooled down his mouth. Looking at the downed Autobot, he chuckled.

"You know your problem Sideswipe? You're too soft. You're weak. You don't have the spark to finish someone off. Just like you almost did to that Crasher girl... But lets bygones be bygones, shall we?"

Sunstreaker readied his hand cannon to aim at Sideswipe, "Goodbye Sideswipe, forever. May you join your brother in the wells of the Allspark."

Sunstreaker's arm cannon warmed up, ready to shoot, but before he could make the shot, he was met with a blaster shot to the foot, making him miss. Sunstreaker stared back to look and see a girl with cyan skin and rainbow hair, now standing with a black tank top, with the Headmaster armored legs, but no armor on the top of the chest except for the gauntlets and gloves on her arms. Her teeth gritted and her eyebrows were cross.

"Back away from my brother!" Rainbow yelled at the top of her lungs.

Sunstreaker chuckled. "You call that worthless piece of scrap your brother?"

Rainbow retaliated by firing another shot towards Sunstreaker, making him groan.

"Yes. I do. Sideswipe is one of the best things that happened to me. Ever since I met him, he's been by my side, making sure I stay safe from people like you. And now its time that I return the favor."

Rainbow just pulled the trigger some more and kept on moving ahead, not wasting any time with the shots.

"Sideswipe isn't weak, he's a strong warrior. Someone who always looks out for his friends and brothers. A true friend. And I'm not about to allow some monster from Cybertron hurt him. I'm never gonna let someone hurt him, and you aren't gonna stand in my way!"

Rainbow didn't realize it, but suddenly she saw her body began glowing a bright blue color. She felt the sides of her head, and saw that pony ears were beginning to emerge, a long rainbow ponytail extended from the back of her hair, and blue pegasus wings formed from her back.

"You want to fight, organic flesh? Then we fight!"

Rainbow's wings flapped hard, which got her body to go up into the air to meet at Sunstreaker's eye level. She readied her fists to begin, and she made a hand gesture, saying to Sunstreaker to start first. Sunstreaker smirked, and he began a running charge, and threw a first punch. Rainbow deflected the punch with her Headmaster gauntlets and she threw a punch across Sunstreaker's face, almost sending him back down on the ground.

Taking advantage of the situation, Rainbow made a kick to Sunstreaker's chest which kicked him even more. Sunstreaker just got back up on his feet and readied arm cannons. He aimed both of them at Rainbow and fired multiple shots from his arm cannons which kept on going. Rainbow just flapped her wings and flew from the bullets trajectory point. She looked back and saw Sunstreaker didn't stop, and he just kept on firing.

Rainbow turned around and soared back down at a lightning speed, with her rocket boots adding more boost. Sunstreaker readied for another attack. Rainbow Dash got closer and closer, and Sunstreaker threw a fist onto Rainbow Dash, sending her flying across the road and making her collided with the ground. She winced in pain, and slowly got back up on her feet. Sunstreaker was about to fire another shot, but he looked at Rainbow's grinning expression with confusion.

"What are you gaping at!?"

Before he could respond, he was met with someone slamming into his back, making him fall back down to the ground. Rainbow looked back up and saw Swoop had flew into their vicinity. He flew up into the air and then transformed into robot mode. He offered a hand to Rainbow, and she accepted, getting back up onto her feet.

"What happened on your end?" Rainbow asked.

"Me Swoop can't fight zombie giant. It keep rebuilding self." Swoop said, pointing ahead of them.

The two of them looked back and saw the Shadowbot giant was stomping among the ground, walking to where they stood.

"Don't worry Swoop, I've just gotta finish Sunstreaker, and you won't have to deal with that giant anymore." Rainbow said with determination.

Rainbow flew back up into the air, and tackled Sunstreaker to the ground. She activated her arm cannons and stood on Sunstreaker's chest, firing multiple shots, not resisting.

"This. Is. For. Sideswipe!!!" Rainbow yelled.

Sunstreaker moaned in pain, and Rainbow stopped to see what she was doing. She was shooting this guy without any mercy. No one of her own side would ever do that. This was going too far.

Rainbow stepped back away, realizing what she was doing and her jaw lowered in shock. But just in case, she held her arm cannons back up, keeping them aimed at Sunstreaker.

Sunstreaker moaned some more and he stared back up at Rainbow, "Go ahead... finish me off. I'm sure Sideswipe will just love it when he realizes that you finished off his only brother."

Rainbow shook her head quickly, "No... I can't! I would never do that to Sideswipe! He's suffered enough, I can't kill you!"

Sunstreaker just smirked some more, "But you know you must, you know you can't let bots like me take your planet... once we spread, we never stop taking control and spreading our plague... so... what are you gonna do?"

Rainbow tried aiming her hands at Sunstreaker, watching them continue to shake and clank, making a loud noise. She didn't know what to do. Shoot an entity that just tried to kill his best friend, or not do anything and let Sideswipe handle this?

Sunstreaker was ready to get back up on his feet, but Rainbow moved quickly and aimed her arm cannons at Sunstreaker's chest, firing non-stop. She yelled as the multiple shells went through his chest, and she didn't even look to see the amount of damage she was causing.

Once she opened her eyes, she looked to see what she had done. Sunstreaker's chest had multiple holes in them, and there were a few purple electricity sparks still going off. Rainbow looked up at the giant, and saw the purple glow in his eye fade away. She looked back at Sunstreaker's possessed body, and the purple glow began to fade away as well. In a matter of seconds, the purple glow faded away, leaving nothing but a blackened and gray body.

The giant soon came crashing down, landing on its chest, making a huge crashing noise, and making a dent in the road. The Autobots that had connected to it, transformed back into their dead lifeless corpses. And all that was standing was Rainbow Dash, trying to keep her balance, and Swoop who had witnessed the entire fight.

Rainbow's legs kept wobbling, and she kept on trying to control her balance. But all the while inside of her head, she felt a huge amount of guilt and shame. She had just killed an Autobot, someone that Sideswipe once loved, and she couldn't take it back. What if Sideswipe didn't want to stay with her anymore? What if Sideswipe yelled at her? What if Rainbow Dash was booted off from the Autobots team permanently?

The amount of pain and shame was enough to make her tumble onto the ground.

Rainbow struggled to get back up on her feet, but as she looked around, something wasn't right. Suddenly everything her started to become... blurry. Her vision was becoming fuzzy, and she started coughing heavily.

"Oh no..." Rainbow coughed in between.

Rainbow coughed some more, but stopped when a strange sight caught her vision. She saw a golden glow coming from Sunstreaker's dead body. A glowing figure looked as if they were coming out of his body, getting back up on his feet. When Rainbow rubbed her eyes some more, she gasped in realization.

"Sunstreaker..."

The ghostly figure looked at Rainbow Dash offering a friendly smile.

"Are... are... are you... you..." Rainbow sputtered. She looked to the side and saw Swoop giving a confused face. "Swoop, do you see that?"

Swoop looked in all directions showing confusion and shrugged his arms, "Me Swoop no see nothing."

Rainbow stared back at the ghostly figure in front of her, and gulped. What did this spirit want? Did it want revenge for its death? Did it have something to say?

The ghost just kept a friendly smile, and then he spoke.

"Rainbow Dash... thank you. You have freed me, from my eternal tomb. Because of you, your planet will live to see another day, because of you, my brother is now safe," The spirit spoke.

"But... but, I killed you. Sideswipe's never gonna forgive me for this," Rainbow said, as a tear went down her face.

"Easy child... Sideswipe knows you had to do what you needed to. I couldn't be helped either way. But because of your actions, I am freed from my prison, and I can now join the well of the Allsparks."

Rainbow blinked for a moment, and tilted her head, "You mean... you're going to... h-heaven?"

The ghost nodded.

"But before I join all of my brothers and sisters, I like you to promise something for me," the ghost said.

Rainbow nodded. The ghost moved forward, taking a few steps closer to Rainbow Dash and kneeled down so he was at eye level with Rainbow Dash.

"Promise me you'll look after my brother. He needs someone to look out for him. Someone loyal, tough, brave... someone he calls, a sister."

Rainbow nodded, "I promise... I promise I'll look after Sideswipe. But... but what if he doesn't want me to?" Rainbow shivered. She still wasn't sure.

"I promise you, he'll want you to look after him. He needs someone like you to take care of him," he said.

Rainbow paused to think for a moment. If the spirit of Sideswipe's once living brother said it was okay, then maybe it was okay. She gave a nod to the ghost.

The former Autobot gave a smile, "Thank you, Rainbow Dash."

The ghost moved back up onto his feet, and Rainbow watched as his golden glow walked right through Sunstreaker's body, and he looked as if he was getting ready to lie back down in the same position he had been in before. He looked back at Rainbow, and gave a salute.

"Til all are one."

Rainbow, with what strength she had left, gave a salute back. "Til... Til all...", Rainbow's vision started to darken a bit, as she was close to passing out, "Til all...are... one...."

Rainbow's vision suddenly went black, and her body fell on her back on the ground. While she was out cold with everyone else, she at least accomplished her mission and made a promise. Hopefully one she would never fail. And hopefully she would be forgiven for her actions.
