Ask the average Star Wars fan to talk about their favorite characters from the franchise and you’ll most hear names like Luke Skywalker, Darth Vader, Han Solo, a.k.a. the most popular and important figures Star Wars has to offer. While names like Skywalker and Vader have dominated Star Wars fandom for four decades now, it’s important to remember that there are hundreds of other characters within the Star Wars universe.
Although many of them are forgettable, quite a few are arguably just as important as the names mentioned above, at least in terms of the impact they’ve had on the larger Star Wars mythos. While you’ve almost certainly heard of a few names on this list, these are some of the lesser known Star Wars characters who are actually really important and have been significant in their own way to the overall story.
Note: quite a bit of this covers stuff from the Extended Universe, which in many cases isn’t technically canon anymore. That being said, until Disney offers us alternative histories for these characters, I’m just going to go ahead and accept the versions that do exist.
14. Barriss Offee
A Jedi Padawan who fought in the Battle of Geonosis, Barriss Offee is a notable Star Wars character because she eventually betrays the Jedi Order and it’s this betrayal that helps pave the way for the Order’s eventual fall to Darth Sidious. Initially, Offee was a loyal and studious Padawan, and was also close friends with Ahsoka Tano, the Padawan of Anakin Skywalker. However, Offee eventually becomes disillusioned with the Jedi, believing that they had lost their way and no longer stood for the principles they were supposed to uphold.
She later carries out a bombing attack on the Jedi Temple in an effort to sow further public distrust of the Jedi and frames her friend Ahsoka in the process. Eventually, Ahsoka is found innocent, but does admit that her former friend had legitimate points about the Jedi and that if they had listened to her concerns, they may have been able to avoid their downfall.
