(Expanded Bay-verse)
Approx. 1,000 B.C.-
Finally! He had found it. He was certain. Megatron looked down at the little blue planet before him. It was here. He could feel the AllSpark calling to him. He was close, so close. Closer than he had been in eons. Finally.
The little bot he carried with him was silent as usual, not sharing in his moment of triumph. Instead, they eyed the planet as they approached it. The signal was coming from the other side and it seemed that Megatron intended to fly over the top to get to it.
Normally, they would have been in stasis as he trekked across the universe but after their brief stop at the Nemesis, they stayed awake, secretly sharing in his excitement at how close they were getting to the goal. But their reasons were not the same as his. Finding the AllSpark meant there was a chance that they could escape from him. It was a small chance but one they were willing to take. Even if it got them killed.
The planet had a fairly dense atmosphere. Megatron had to divert pretty much all of his remaining energon reserves to his shields to protect them from the heat caused by the drag. Even hidden beneath his plating, the little bot could feel the nearly overwhelming rise in temperature.
A thought slipped from the secondary processor to the main one. It's time. Are you ready?
Indeed. It was now or never. Megatron's energy levels were extremely low. If they acted now, he would not be able to do anything to stop them.
The main processor sent a command back without hesitation. Do it!
Megatron did not understand why he suddenly transformed while he was still so high in the atmosphere until he saw the little bot break away from him. He snarled and attempted to reach for them, but his body would not listen. His energon levels had dropped far too low and he had pushed himself beyond his limits. They had taken advantage of that. Now he was plummeting towards the planet's surface with no way to slow down or even shift his position.
{You will regret this, Scythe!} he roared across the commlink.
They looked back at him. Both of the appendages hanging off the left shoulder lifted, weapons activating, and they fired. The shots struck him in his shoulder, not doing much damage but it did set him spinning as he fell. He continued to rage at them over the comms, but they shut him out.
Colliding with the ice nearly broke him. The impact knocked him offline. His twisted frame lay at the bottom of an icy crater that was quickly filling up with more freezing liquid and thanks to the sub-zero temperatures, he would stay there for a very long time.
They did not bother to watch him fall. Instead, they turned their face to the south, in the direction that Megatron had been headed, the direction of the AllSpark. They did not have any alternate mode, so they spread out their body as much as possible, even flaring their armor, to catch the air. Even if they had one, it would have not been for flight. Firing their weapons had helped a little to move them so they fired again with both of them.
They managed to clear the icy north pole and came down not far from the shore of the closest actual landmass. Before they hit, they blasted the surface in an attempt to break the surface tension and soften the impact. As they sank to the bottom, they analyzed the liquid around them. Mostly dihydrogen monoxide with some minerals mixed in and quite an abundance of organic material. Fascinating but not what they were after.
Once they hit solid ground, they got up and started walking, again to the south, the organic aquatic beings swiftly fleeing out of their path. Finally, they trudged out of the water and onto dry land. They stopped for just a moment to shake off some of the wetness.
Do you have it? Are you ready? inquired the main processor.
The signal indicating the AllSpark's location came up on the HUD. Ready when you are.
The main processor pinged a confirmation as the frame bent into a runner's crouch. Then they were off like a shot, running faster than any of the organic beings on the planet could follow. And they kept running without pause until they reached the AllSpark's location.
They found that the artifact was buried at the bottom of a river, only the top corner could be seen in the mucky depths. They jumped in. The appendages hanging off the left shoulder latched onto the AllSpark as they collapsed against it, falling offline from exhaustion, while the river rushed by.
