You were an Autobot who had been with the team ever since the mid-term of the war, so you had mild experience of the war. Since you joined, you and Wheeljack had a strong connection and explored galaxies together most of the time. Sometimes, you both would crash out at the base to either get your ship fixed or just to get rest.

Half of the base was covered in black ashes, along with you, Bulkhead, and Wheeljack. You coughed up black smoke as you tried wiping the ashes from your faceplates as Ratchet and the others rushed to your location. Your optics were about to tear up from the smoke and ash that was in the air.
