A/N: back again. Still sick. Enjoy.

All suggestions welcome. Remember the 'Cons.

Disclaimer: i do not own Transformers:Prime. I only own Xenia.

*Recap*

I scanned the area and stopped near the main power system.

There was a 'Con inside the building.

'Fragfragfragfrag!' I thought as I drove around the building towards where the 'Con was. 'And I let the kids go in there by themselves! Optimus is gonna kill me!'

I scanned quickly for security cameras and transformed. I looked around for a way in and saw a skylight. I scaled the building and peered in.

The space was like a warehouse. A black and purple 'Con was kneeling in front of a black box looking thing. Hey, don't ask me what it is. I'm a warrior and field medic, not an engineer.

Anyways, he was facing away from me with these tentacle-looking things connected to the box. One of the tentacles were out the door, for some reason.

I changed my servo into my blaster and took careful aim. But then, I heard a scream just as I fired and I missed by an inch. The 'Con turned towards me and I nearly fell through the skylight.

He had a full face visor, covering his entire face as the name suggested. But on the screen, it showed three overlapping circles. Then it changed to one of the security feeds that showed the kids against the wall.

I regained my composure and jumped through the skylight. I was aiming to land on him but he was pretty fast. He dodged me and brought up one of his tentacles to attack me.

I drew my sword and sliced at it. It withdrew and struck again. He brought out another tentacle that was holding an axe. A fragging axe! I let one servo go of my sword and held the axe back.

But another tentacle came out and hit me three times in the stomach. I doubled over in pain and I thought he was going to finish me off, but the three circles on his visor aligned and he cut a thick cable with the axe. Then he leaped up to the hole in the skylight and turned around to look at me just as the kids came into the warehouse.

Miko took out her phone and took a photo at the same time I did so I could ask ratchet about him. And it seemed like he took picture as well. Then he transformed into a very slim jet and took off.

"Why is it leaving?" Miko asked.

"My thoughts exactly." I agreed.

Raf knelt down in front of the severed cable and said, "He cut the hard lines. The dishes are locked onto Cybertron. For good."

"Scrap." I rubbed the back of my helm. "Well, we tried our best. Please tell me you found something useful."

"I downloaded the same math that we found on the Decepticon warship." Raf said holding up a little white stick. "You know, the same one from Miko's picture."

"Nice job, Raf" I said. "Well there's nothing we can do now. Let's get back to base."

Meanwhile, at the Space bridge

"Now, Starscream?" Megatron asked impatiently.

"Now." Starscream confirmed and pushed a button.

The space bridge lit up a brilliant blue-green, resembling the ocean.

Megatron emerged on top of the Nemesis with a massive amount of Dark Energon.

"AT LAST!" He yelled and threw the Dark Energon into the vortex.

Optimus looked up and saw it streaking towards the space bridge. He changed his servos into blasters and shot at it, but the Dark Energon had too much velocity and it charged straight into the swirling blue-green vortex.

It emerged from the other side of the space bridge and hit Cybertron;s surface. Purple light consumed the planet and soaked into the very surface. One by one, the deceased of Cybertron rose, their optics glowing Dark Energon purple.

On the space bridge, Bulkhead asked, "So, how do we beat a whole planet of the undead?"

"Optimus!" Ratchet yelled through the comm. link. "I'm registering a rapidly expanding mass in their space bridge vortex. One with a peculiar energy signature."

"Dark Energon." Optimus confirmed their suspicions. "Ratchet, we must destroy the space bridge."

Xenia and Ratchet looked at each other in shock.

Optimus continued. "There's enough live Energon coursing through it to achieve detonation, but we lack the firepower to ignite it."

"If I knew how the space bridge was engineered, I might find a technical way of accomplishing that feat." Ratchet responded.

"Hey, Raf. What about that math you said you downloaded?" Xenia asked him.

He held out his jumpdrive towards Ratchet.

Ratchet thought hard, then said, "Optimus, I must say, the space bridge is our sole hope of ever returning to Cybertron. Are you certain its destruction is our only option?"

If you only heard it like that, you would think Ratchet was being selfish. But if you've known him for as long as Optimus has, you would know that he was asking as a survivor of a dead world.

"I'm afraid so," Optimus said.

"Then by all means, let us light our darkest hour." Ratchet declared.

Optimus smiled under his battlemask and said, "Autobots, take your positions and follow Ratchet's lead!"

They all ran off to where Ratchet told them to go.

"...While I make my stand."

*Xenia's POV*

Ratchet and I were looking at the schematics on one of the screens while the humans, including Agent Fowler, who was feeling much better, were looking at another screen that displayed the progress of the undead.

"These things are getting closer." Fowler pointed out. "That's bad, right?"

"Ratchet, Xenia, we're in position." Arcee said through the comm. link.

I brought up the schematics on the main screen and said, "Okay, listen closely, Arcee. Pry open the main grid. There should be a few glowing valves that control the space bridge. First..."

While I was explaining how to do all of this, Ratchet was locking onto their coordinates so we could get it open at a moments notice.

In the background, I could hear Bulkhead saying something along the lines of, "I didn't know Xee was this smart."

"Bulk, shut your afterburners." I said, scowling. "Anyways, follow the line from the flow regulator to the Energon pump. There should be one more valve."

"I see it." Arcee replied.

"Good. To turn all that power against itself, all you have to do is reverse the current." I instructed.

Arcee grunted and said after, maybe 3 seconds, "Current reversed."

"Yes!" Agent Fowler... fist pumped? "Right?"

"I'll activate the ground-bridge." Ratchet rolled his optics.

"Phew..." I sighed. I think I used up my daily smarts quota.

"Optimus, the ground-bridge is ready and waiting." Ratchet reported.

"Autobots, JUMP!"

"Do you think they're...?" Raf asked, worriedly.

Ratchet checked his health meter. "4 life signals, one very faint."

That's when Optimus came through. One safe, nothing life-threatening on him; just a lot of dents and scratches.

Then, Bulkhead came through. I walked up to him and gave him a hug.

"Bulkhead!" Miko squealed. I smiled and lifted her up so she could climb on Bulkhead's shoulder.

Two down, two to go. That meant either Bumblebee or Arcee was damaged. I wasn't looking forward to either.

Then, Bumblebee came through carrying Arcee. She had a big scorch mark just shy of her Spark chamber. We all gathered around her while Jack stood right in front of her.

"We lost one this week; by the Allspark, don't let it be two." Ratchet muttered to himself as he got his lab ready.

I scanned her and sighed in relief. "Don't worry. It's not that bad."

"Arcee..." Jack put his hand on her limp one as she started to reboot.

"Jack. Really?" She asked, seeing his eyes tear up a bit. "There are other motorcycles in the world."

"But you're my first." Jack snipped back.

"And Megatron?" Ratchet asked, now that the danger of anyone offlining was past.

"Not even he could have survived ground zero." Optimus said.

Bumblebee helped Arcee stand up and she smirked at the humans.

It seemed like Miko thought of something because she walked towards Optimus and said, "So, is this the part where you say goodbye and tell us we need to forget we ever saw you?"

All Optimus did was smile slightly at her.

"Without a means of leaving this world, we Autobots take strength in the bonds we have forged with our three young friends - true warriors. If not in body, then in spirit.

"My name is Optimus Prime, and I send this message. Though we did not choose to be of Earth, it would seem that we are here to stay.

"If you approach this planet with hostile intent, know this: We will defend ourselves. We will defend humanity. We will defend... our home."

A/N: Alright, Darkness Rising is finally done! What do you think? I would have made it longer but it's kinda long already.

Tell me what you think. All suggestions welcome. Remember the 'Cons.

Thanks for reading and please review.
