Forum:KB:Robot Head?

Has there been any characters in the Legends continuity (or any other) to recieve a cybernetic replacement for their head? or to have had significant cybernetic modifications to their head. I heard there was a character with a cannon for a head, and I have heard that in an earlier draft of Star Wars that luke skywalker was an old man with a robot head... any truth to these rumors? ralok (talk) 06:30, June 30, 2014 (UTC)
