I couldn't decide whether to do Luke or Leia for the L, so why not do both? Obviously as two of the original main characters there are a lot of figures for both Luke Skywalker and Princess Leia Organa.
Just for Luke there's original, Stormtrooper disguise, X-Wing pilot, Awards Ceremony, Hoth, Snowspeeder Pilot, Dagobah, Bespin, Return of the Jedi, Endor, Last Jedi Master
By comparison Leia has fewer iterations: Original, Hoth, Bespin, Bounty Hunter, Slave, Endor, Force Awakens. (Strangely the Bespin is her white jumpsuit not the red dress she wore to Lando's little reception. They also seem to be missing the awards ceremony, Ewok village, and Last Jedi versions.)
Did you ever realize they had so many wardrobe changes? The only ones I have in the Black Series are Bespin Luke, X-Wing Pilot Luke, and Hoth Leia. In the old days we had pretty much all the ones they made, which were just about all of those listed above (for the original 3 movies). In the 90s I got the Dagobah training Luke and later the Bespin Luke with the pop-off hand! By then they had slimmed down the figures so he doesn't look like Ahh-nold Schwarzenegger. I also have the Slave Leia figure, which for its time was about as sexy as a 3.75-inch figure could get.
