Boba Fett didn’t originally start out with that design we know and love from Empire and Jedi. The original designs show a bounty hunter that looks closer to a Stormtrooper. Boba Fett’s design evolved during the design phase and eventually became the Mandalorian we know.
You can see the evolution below. It was still cool looking, but less defined. Not as unique. It definitely lacked character and presence. I’m glad it kept evolving, because the instant I saw Fett on screen, I knew this guy was not to be messed with. THIS was a bounty hunter that inspired fear.
