Mara Jade is an exceptionally powerful Force-user in the Star Wars Legends continuity, whose skills and aptitude are comparable to those of Luke Skywalker. While Mara Jade is no longer part of the modern Star Wars canon, she was created for the franchise’s first official continuity, the Expanded Universe, which became the alternate Legends timeline in 2014. Mara Jade is famous for being one of the Empire’s most powerful Force users (aside from Emperor Palpatine and Darth Vader) and later one of the New Jedi Order’s most formidable Knights, making comparisons to Luke Skywalker inevitable.
