Lekku are certainly important to Togruta, but in “Star Wars” canon, there’s far greater importance bestowed upon them for Twi’leks. This is made clear from a quote in the “Solo: A Star Wars Story” tie-in novel, “Last Shot,” by Daniel José Older. Kaasha Bateen, a Twi’lek, tells Lando Calrissian, “It is something approaching the sacred, really. A vital part of our identity.” And it’s easy to see how that’s the case in other media.

For example, Twi’leks’ lekku can be used to pick up objects. And while Twi’leks have their native language, Ryl, their lekku also function as a form of communication. Raising the right lek means “Hello,” while lowering the left lek means “Goodbye.” In “Last Shot,” Kaasha continues with how lekku can communicate things beyond mere pleasantries, “For the Twi’leks, the caressing of the lekku is an act that is beyond mere sensuality.” It’s also been noted how sensitive the lekku is for Twi’leks; losing one can cause severe harm and result in debilitating injury.

The Ozrelanso have not had as many “Star Wars” appearances as the Togruta and Twi’lek, so little is known about their lekku’s significance. But overall, it’s easy to see how these appendages are critical components of the aliens’ identities. Not only does it make them stand out among other characters, but they have developed a mythology all their own.
