Ahsoka Tano, a character that went on a journey unlike any other in the Star Wars franchise. Ahsoka’s Fate is intertwined with that of Anakin Skywalker/Darth Vader and both are truly tragic - Ahsoka was unable to save Anakin from his downfall before she was even sketched by Dave Filoni for the first time or any of her dialogue was written.
Despite the fact that Ahsoka left the Jedi Order, I believe past the 5th season of the Clone Wars her core narrative was about being more of a jedi than other actual jedi.
