Probably not. If you are asking about the crash of the Khetanna, Jabba the Hutt’s sail barge during Star Wars: Episode VI Return of the Jedi, Boskk was probably able to survive due to his regenerative abilities. If the cover pictured here is accurate, Bossk is scheduled to appear in the Star Wars canon comic book Halcyon Legacy 5 this summer, August 2022. This is significant regarding Bossk’s mortality because the timeline for the Halcyon Legacy series is after the Battle of Endor and the Empire's destruction.
