This review of Star Wars: Rogue One — Cassian & K-2SO contains minor spoilers.
Now we know why K-2SO handled that sidearm with such lethality toward the end of Rogue One: A Star Wars Story.
We also know a great deal more about the nature of the relationship the ex-Imperial droid shared with Rebel spy Cassian Endor, too. This story is a splendid example of how comics can be used to build up and add to the mythology of Star Wars films.
Written by crime-fiction novelist and comics writer Duane Swiercyznski (check out his work on Dark Circle Comics‘ The Black Hood), this one-shot provides a solidly entertaining origin story for Cassian Andor and K-2SO. The cover is by Julian Totino Tedesco with a variant (pictured) by Chris Samnee.
