Annikin Starkiller was the proposed name for the lead character in the what would become Episode IV and appeared in the rough draft. He would have played a similar role as Luke Skywalker in A New Hope, although in his cockiness and brashness he also resembles Han Solo. He became the source of Luke's father's name, Anakin, in the third and later drafts.
In the first draft, Annikin was renamed "Justin Valor." This name was dropped in later drafts. While there was no one named Annikin or Anakin in the second draft, the name reappeared in the third and earliest versions of the fourth draft. During the filming of Episode IV Luke's surname was changed from Starkiller to Skywalker, his Jedi byname in the second draft.
