A/N: I don't remember all that was requested before. I remember a Starscream/Astrotrain one. I will do that one still. I just don't know who requested it and it will take a while. So to keep things in line, put your requests in the reviews or PM me, and I will write them down, what you want in them, and who requested them. So this one was requested by Optimus girl. Hope you all enjoy. Names are picked randomly from a huge list I made over the years of Transformers OC names I've made up. Some may be similar to other stories, but I am not stealing them. I'm gonna do this in Primeverse SG, but just calling it SG. It can be any series really.

Optimus heaved cool air into his heated systems. The fight wasn't over yet. He looked over at his darker copy, knowing what he had to do. He could hear Megatron behind him, shouting not to do it. The Prime looked over to his friend, the one that had taken him in and helped him when he was transported to this strange world. He looked over the large gash in the silver mech's chest.

"I have to Megatron," Optimus said, turning to look back at the downed dark Prime.

He walked over to Nemesis Prime. He pried the broken chest plates open, separating his own at the same time. He used the Matrix to merge with the dark spark, using the power of Primus to purify him. The light spread out and hit the other Autobots. Nemesis screamed, trying to get away. Optimus pressed on, growing weaker as he used some of his spark.

"Optimus, stop!" Megatron pleaded. "You're killing yourself! There has to be another way!"

Optimus knew he was almost done. He felt Megatron collapse next to him, holding him close. The Prime's world started to fade out. The process finished just as he fell unconscious.

"Optimus?" Megatron asked. He gently held him, checking for life. It was still there, but weak.

"Megatron?"

The silver mech turned to see Nemesis looking at him, spark a bright blue that matched his optics.

"It worked. You did well Optimus," Megatron whispered. He turned back to Nemesis, staring into those blue optics. "Hello old friend."

"My spark feels different," Nemesis said. "Lighter. I feel better. What have I missed?"

"A lot. I will tell you after we get Optimus to Knock Out," said Megatron. He lifted the mech up, walking back to his medics. Nemesis followed, staring at the mech.

~~~000

Optimus onlined his optics, groaning a bit as bright lights filled his vision. He covered them, sitting up slowly. He looked around the medibay, spotting Knock Out and Breakdown. The blue medic turned to see Optimus awake and grinned. He called Megatron on the com link as he went to the Prime.

"Glad to see you are awake," the medic said. "Megatron had been worried about you. He went to get proper rest a few joors ago with Starscream."

"How long have I been out?" Optimus asked.

"Almost a deca-cycle," he answered. "You three are lucky to be alive."

"Three?" Optimus asked.

"You're carrying Optimus. It must have been from when you were prisoner of Nemesis deca-cycles ago. They're perfectly healthy," said Knock Out, giving the Prime a datapad with a picture of the small sparks next to his own.

"Optimus!" Megatron shouted, running up to the mech and hugging him. "I'm so glad you are awake."

"I am glad to see you as well," said Optimus, hugging his friend back. "How have you been?"

"Restless. Starscream has been making sure I take care of myself. We found out recently he is sparked," said Megatron. "I thought you were going to die. Nemesis has been by your side constantly. He should be almost done fueling."

"It worked?"

"Yes it did. Thank you for that. The rebuilding of Cybertron has already begun. Without you, we would still be at war."

"Optimus."

The two turned to see Nemesis walking up to the Prime. He grabbed the black servo in his own, kissing it lightly. Megatron gave Nemesis a knowing look before leaving the two alone, ushering Knock Out and Breakdown out. Nemesis sat on the berth next to Optimus, staring deep into his optics.

"Thank you for helping me," Nemesis said. "And... I am so sorry for everything I had done."

"All is forgiven," Optimus said, placing a servo on his chest. "Out of the chaos rises beauty. Without you, the sparklings I now carry would not have gotten to live a life."

"Sparklings? You're... carrying my heirs?" he asked.

"Yes," Optimus nodded. Nemesis grinned before kissing Optimus deeply.

"I admit I find myself in love with you," said Nemesis once he broke the kiss.

"I as well," Optimus said, kissing the other Prime.

~~~000

"You're staring," Optimus pointed out, looking up from his datapad.

"I can't help it," Nemesis smirked. "You're sexy, especially when carrying."

The darker mech got up and wrapped his arms around his mate's waist, rubbing his abdomen where the sparklings grew. Optimus shivered as Nemesis kissed the back of his neck and shoulder.

"How did I end up so lucky to have you?" Nemesis asked.

"I should be asking the same," Optimus laughed. He got a ping, checking the message. "It would seem it is almost time to go greet Megatron and Starscream. Go get ready. You can have me later."

"Hahaha very well," the mech said, heading to the washracks for a quick wash.

The two headed out, meeting up at a local energon shop. Megatron was feeding Starscream an oil cake, the seeker laughing. The couple saw their friends, motioning them to sit with them outside the window. Optimus took a seat next to Starscream. Nemesis went into the shop to get some treats and energon for him and his mate.

"How are you fairing with carrying?" Starscream asked.

"It is hard at times, but it will be worth it," Optimus said, lightly rubbing his abdomen.

"I agree. Wish this little fragger will stop kicking so hard," Starscream said with a smile. "Soon though, they will be here and causing trouble."

"Indeed," Optimus agreed, knowing any solar cycle now, he and Starscream could be delivering their sparklings.

~~~000

"Nemesis," Optimus panted. "I don't think I can go anymore."

"You're almost done sweetspark," Nemesis encouraged. "Just a bit more."

Optimus nodded, but felt like he had no energy. The second one was taking its own sweet time coming. After what felt like joors, the final sparkling came. Nemesis looked over at this sons, the eldest being black and red with blue streaks and the second being blue and silver with black highlights. Both had what appeared to be wings on their backs.

"They look perfect," said Nemesis. "You did great sweetspark."

"Have you decided on names?" Ratchet asked.

"The eldest is Thunderain and his twin is Skywing," said Nemesis.

"Excellent," said Ratchet. His com beeped with a message. "And it would appear Starscream has delivered a healthy seeker mechling named Starfall."

"We will say hello to them another time," the darker mech said. He looked over at his tired mate. "Get some rest sweetspark. I will fuel and watch them."

Ratchet left the two alone with their creations. Nemesis pulled the berth that held his sons closer, getting a good look at them. He gave each of them energon from fuel lines meant for sparklings. He smiled, loving his new life and family. Life was good. And he wouldn't change anything about it.
