You were a rogue bot, taking a pit stop on the moon for some unknown reasons. As you were briefly scouting the area, you came across a lifeless frame that was in pretty bad condition. You examined it further, seeing it was a decepticon-- and it's injuries were intentional. You had a good morality, so you wanted to help. You carefully dragged him to your base, seeing if you could possible reactivate him by toying around with some tools. You managed to fix a few things, but later took a break from working on him.

Unbeknownst to you, as you were gone your work was put to use and he flickered back to life-- looking around nervously in both fear and confusion-- knowing the last thing he remembered was being chased by Megatron.

You walked back into the room shortly, holding a tool as you paused, staring at him in shock. Your efforts worked-- and you reactivated him.
