Epilogue.
---
Optimus pulled his sword from Galvatron's body. It slumped down on the ground, lifeless once again. He walked to the main battlefield, now devoid of any combat. The Autobots, Sam, and NEST forces stood together, surrounded by Decepticons they had laid back to rest. Ratchet looked at Roadbuster, who was staring at what remained of Topspin. Sam, Lennox, and Optimus exchanged nods.
Though we lost many, we gained much as well. We had never forsaken the humans, and in turn, they have not forsaken us.
Sam stood in yet another base, waiting to see what would happen. He felt a tap on his shoulder from someone behind him, then looked at it. A NEST badge was now on his combat uniform, and when he turned around, he saw Lennox.
Though perhaps we will always have enemies...
The bodies of the Decepticons were loaded onto C-17s. Sam later passed by a room in the base with only the weapons taken from the corpses inside. On a screen he saw the corpses in a metal room, being crushed between two walls, and smiled.
So too will we always have friends and trusted allies, who we will face them beside.
Outside the base, Ratchet shot Dino with his repair ray for a few seconds, then transformed it back into a hand and gave him the thumbs-up. Optimus levitated the Matrix in front of himself for a few seconds before grasping it in his hand and looking to the sky.
I am Optimus Prime, and I send this message to any surviving Autobots taking refuge among the stars. We are here. We...are home.
