First drafts
Every story has its early phases, where characters and designs are completely different from the ones that make it to the final version. For example in Star Wars, Luke Skywalker was supposed to be named Luke Starkiller and could have been an alien from a different planet altogether and not human-like.
There were even talks to make Luka a female and to have Han Solo as a giant fish-like alien instead of the handsome space cowboy that we know and love him for. If any of these ideas made it into the final movie, who knows if it would have been a success?
