PROXY was a prototype holodroid who served as a companion and long time friend of Starkiller (secret apprentice|Starkiller]] and traveled with him on the Rogue Shadow.
PROXY was equipped with advanced hologram technology that, when coupled with its built-in servos, would allow it to change appearance and adopt a wide range of disguises. He was a witness to his master being knighted by Darth Vader and travelled with him when he was sent to eliminate Rahm Kota in a TIE Fighter Construction Facility over Nar Shaddaa.
Behind the scenes
PROXY was conceived by The Force Unleashed producers as "not C-3PO, not HK-47, but somewhere in between." PROXY was voiced by David W. Collins.
