Rogue One - Cassian & K-2SO Special 1

Rogue One - Cassian & K-2SO Special 1 is a canon one-shot comic book created to show how Cassian Andor met the Imperial security droid K-2SO prior to the events of Rogue One: A Star Wars Story. The issue was written by Duane Swierczynski, illustrated by Fernando Blanco, and published on August 9, 2017 by Marvel Comics. It was later collected in the trade paperback Star Wars: Rogue One Adaptation.

The events of the comic were not adapted for "Who Are You?", the eighth episode of the second season of the television series Star Wars: Andor, which instead established that K-2SO was a security droid used in the Ghorman Massacre that Cassian salvaged after severely damaging it in his escape from the city of Palmo on Ghorman. Series creator Tony Gilroy was aware of the comic, however chose not to adapt the events, instead choosing to write a new origin for K2.
