K-3PO

K-3PO was a protocol droid serving with the Rebel Alliance during the Galactic Civil War. Like most droids serving with the Alliance, K-3PO was old and in need of repair. His previous owner was a strategist during the Clone War and had dumped a lot of strategic data into K-3PO's memory banks, and since his memory had not been erased for a long time, K-3PO began to gain some of this strategic knowledge. Because of this, the Rebel Alliance decided to grant him the rank of lieutenant and give him a station in their control center on Hoth.

K-3PO commanded the droid pool on Hoth and even aided in the defence of the base and the subsequent evacuation that followed when the battle turned sour. Unfortunatly, K-3PO was destroyed when his command station exploded, burying him waist-deep in ice and metal and rendering him unsalvagable. However, his memory case was salvaged for future use.

Apparently K-3PO and C-3PO did not get on well, as K-3PO lacked personality and was seen as too inhuman by C-3PO.
