The Renegades expansion gave Destiny 2 players a lightsaber, the Praxic Blade. Like the real deal, you can change its colors in-game through unlockable Dark Matter Crystals (or Kyber Crystals, in Star Wars terms). They're mostly unlockable through gameplay, though of course some are in the Eververse Store.
Your new weapon of choice is complete with deflections, customizable colors, and even a reference to an infamous meme with Obi-Wan and Anakin, bringing quite a lot of Star Wars to the Bungie franchise.
