I'm not sure how femmes actually look like during pregnancy or giving birth, so if someone would be willing to help me with that I would greatly appreciate it :)

Present

Jackson, Nevada-Autobot Base

The alarm went off in the base, and Jack turned to the screen, "Uh, Optimus? The 'Cons are on the move again," Optimus walked over to the screen, and saw the moving signals.

"I guess Bulk didn't set them back as bad as we thought," Miko said, as the others joined him. Optimus turned to them, "We have to go after them."

"With only three of us?" Bulkhead asked, and Bumblebee nodded with his statement.

"As much as I wish to leave the Decepticons alone, we do not know what Megatron has planned," Optimus said, shaking his helm, "We must go investigate," They nodded, and walked over to the ground bridge. Arcee got up, and walked over to them, "Arcee, you know you can't come."

"Optimus, you're short warriors, and you need me," she said, crossing her arms. Arcee was now visibly showing that she was carrying twins. Optimus had called Wheeljack to come help them while Ratchet and Starscream were gone.

"If Megatron sees that you're showing, he will be only thrilled to kill your twins, and we don't want that," Wheeljack said, walking over to the bridge. He punched in the coordinates, and turned to Arcee.

"I know," she said with a sigh, and walked over to the controls, "Ground bridge operator," Optimus smiled at her, and she switched on the bridge. The four bots walked through, and Arcee shut off the bridge. She began to walk over to Jack when she placed a hand on her stomach panel, "Oh!" she said, a bit surprised. Jack looked up, alarmed.

"What it is? Do we have to call Optimus back?" he asked worried. Arcee shook her helm.

"One of them is kicking," she said with a smile, and sat down. Jack walked over, and sat down next to her. He saw the glow on her facial plating, and it warmed his heart. He was glad she was smiling for once.

Since Ratchet and Starscream had been gone-two weeks exactly-Arcee had been moping around the base, and would burst into tears every five minutes. Bulkhead had mentioned that she looked sad one day, and Arcee had ran out of the room, sobbing. Wheeljack assured him that it was because her systems were out of whack because of the twins, and Arcee had nearly ripped his helm off by thinking he thought she was crazy. It seemed only Optimus and Jack could calm her down when her emotions swung like a pendulum.

Miko and Raf glanced over at them, then turned back to their homework. They weren't doing homework, they were planning a baby shower for Arcee. Miko's logic was if humans can have them, then bots should be able to have them as well. Optimus and the others knew they were planning it, and Jack had to distract Arcee when the day of the shower came.

June was more than happy to help them with the plans, as she was excited for the twins as well. Everyone was. They had never seen baby Autobots before, sparklings which is what Wheeljack called them. They were very excited, almost as excited as Arcee.

"Ok, so I'm going to get them blankets, one pink and one blue," Miko said.

"Why one pink and one blue?" Raf asked, looking up from the list.

"Well, Wheeljack said one was a boy and one was a girl, duh!" she said, and wrote something on the list, "We should make them a mixed CD or something so they can listen to it and fall asleep," Raf nodded, and glanced over his shoulder at Arcee.

"She's gonna be so surprised!"

Megatron turned around and saw the drones mining for the energon. He smiled, and walked over to where Knock Out was, "This will surely catch Optimus off guard, and give us the opportunity to get the machine back," Knock Out nodded as Megatron stood next to him, "And then I can go back in time and kill Optimus, Ratchet and Starscream," he said with a smile. Knock Out chuckled.

"They would never expe..."

BANG!

Knock Out and Megatron spun around, and saw one of the mines had exploded, "OPTIMUS!" Megatron roared, and transformed, tearing off towards them. Knock Out turned around and was tackled by Bumblebee.

Bulkhead tossed the drill out of the way, and ran towards Breakdown, his wrecking ball out. Breakdown dodged his swing, and punched Bulkhead in the facial plating, sending him backwards. Bulkhead moved out of the way as Breakdown's hammer came smashing down. Bulkhead got up, and was hit in the face by the hammer, landing on his aft.

Optimus grabbed onto Megatron's wings, and the two collided into the side of the cliff. Optimus covered his helm as the rocks fell down on him, and slowly pushed himself up. Megatron grabbed him by the throat and slammed the Prime into the wall, "You think you can keep the time machine from me?" he snarled, "You won't be able to stop me from killing you once I get a hold of it!" He released the Prime, and transformed, taking off into the air. Breakdown and Knock Out quickly followed, tires screeching as they drove away. Optimus rubbed his throat as the others approached him.

"What did he mean by stop him from killing you?" Wheeljack asked, once they were around Optimus. Optimus closed his optics, deep in thought, then opened them. He had a serious look on his facial plating.

"Megatron's plan was to go back in time, before the war, and kill me so the Autobots would have never come together, leaving him to rule Cybertron," Optimus said gravely.

"I guess we're lucky Starscream and Ratchet went through, huh?" Bulkhead asked, as Bumblebee called for the ground bridge.

"Depends," Optimus said, as the ground bridge appeared and they walked towards it.

"Depends on what?" Wheeljack asked.

"Depends on if they mess around with events that already happened and change the future as we know it."
