In 1999, when The Phantom Menace was released, Darth Maul was positioned, at least briefly, to be the successor to Darth Vader. But after Obi-Wan Kenobi seemingly sent Maul to join the Force at the end of Episode I, Maul’s career as the next Vader was, seemingly, at an end. This meant that Maul and Vader never got to face each other in a lightsaber duel — that is, until 2001. In a non-canon comic book anthology series called Star Wars: Tales, Maul and Vader were pitted against each other in a kind of Dark Side test devised by Sidious. This duel happened in Tales #9 from Dark Horse Comics, and both then and now, this fight has never really depicted a true canonical showdown between the two Darths.
But that’s changed. In the finale of Star Wars: Maul — Shadow Lord, a canonical fight between Darth Vader and Maul has finally happened, and it's epic.
