What was one of Yoda’s original names in the first draft of The Empire Strikes Back?

The answer is: Buffy. Would a little green mentor by any other name be as wise? George Lucas seems to think so since Yoda almost had a name suited for a vampire slayer. It’s hard to imagine, but Yoda’s original name was actually Buffy. Screenwriter Leigh Brackett later changed it to Minch Yoda before dropping the “Minch” altogether. Source
