His black helmet is almost as recognizable as the sound of his breath. He appears on "best of" lists as often as "best known." He's the original villain of Star Wars, and the lynchpin that holds it together, sometimes as protagonist, sometimes as antagonist, and sometimes as aspiration. Darth Vader is without question one of the greatest villains of all time.
But something happened to Darth Vader over the decades. Somehow, the character grew somewhat stagnant. Whether it was simply that other villains like The Joker continually reinvented themselves and stepped up their game or just a lack of exposure (sure, a video game here and there, or a comic book miniseries, but nothing major), and even competition from other Sith Lords and an extended run as one of the "good guys" in his original Anakin Skywalker persona in three films and six seasons of a TV show, it seemed like Vader's reign may have been over.

Through the canon material that's come out in the last few years, we've seen Vader go from memory to feared superpower once more.
