Yeah the head is off a junker Landquake I had laying around.
As for the background, I'm going to be redoing pretty much all the SWTFs I have. I'm going with a storyline where when the great war was going on and Prime saw that they were going to run out of Energon he started sending out teams to search for new sources.
One such group of Autobots was attacked by a Decepticon team sent to track and obtain and Energon they might find, and during the battle both ships got sucked into a wormhole. When they got spit out the other side all of them were in stasis lock. The ships floated a further through space and then crashed on a planet at the outer rim of the Galactic Republic. A few hundred years later group of salvage scavengers found the ships and finding no life and impressed with some of the tech basically tore the ships and the bots inside apart.
By some fluke the memory cores and other key systems from the bots ended up getting sold off and eventually integrated into new ships over the years that followed. Interaction with a maintenance droid inadvertently reawakened one of the Autobots, who finding himself unable to transform and with no knowledge of what had passed since the battle began secretly searching for and reawakening his comrades.
Meanwhile one of the Decepticons was awakened by a scientist who had become interested in the alien technology he'd bought of the scavengers and began awakening his own brethren.
However do to the initial damage to their systems, the later tinkering by the salvage group and the various individuals who figure out ways to merge their tech into their ships all of the Transformers have found themselves changed, both physically in that they have to modify themselves and relearn to Transform, and in the fact that for most of them their memories are damaged.
So short answer yes its in the Star Wars universe, or at least a version of it. This guy is still trying to determine his allegiance. He was awakened by the leader of the Decepticon group, but he has fragmented memories of serving with the Autobots. He's also been influenced by the dark side of the force, which is what has brought all the Transformers out of stasis to begin with. (I'm ignoring Episode one and the tiny bacteria is the Force crap
) They've all become hybrids who no longer need Energon to survive, their systems feeding directly off the source, making them all targets for both the Jedi and the Sith.
