IG-88 Death Star 2

The blackness of sensor deprivation was distressing, but unavoidable. Humans would have called it "unconsciousness" -- but when IG-88 finally reawoke after a month or so of stasis, he found himself in an immense new world of data input.

He had left his clunky body behind with the other droids -- the last of his model -- and now he was the Death Star, the same powerful and relentless and efficient mind residing within an extraordinarily powerful new body, a completely different configuration. IG-88, whose prior experience had been entirely within his massive humanoid shape, was not quite as mobile... yet. But he experienced new input through a million additional sensors, automated extensions of himself
that were connected to the Death Star's computer core. He could feel the power like a chained supernova burning at the heart of his central reactor furnace. The sensation was marvelous. He took great satisfaction in seeing just how easily all of his plans were reaching fruition. Soon, his droid revolution could proceed.
