Lost...
That's the only word to describe me.  I'm adrift in space, floating...
Hopeless.
My brother, too, is gone.  So is Optimus Prime.  
All of my companions are gone, crash landed.
I was not like them.  I was not lucky.  I crashed on a different world.  One that is red, barren, and lifeless.  I was knocked out of our group by a rogue asteroid, sending me hurtling through space and onto the surface of this dead hunk of rock.
My repairs are almost complete.  I will join my friends soon.
Soon I will fight with them once again.
"I'm on my way, Autobots."
