How much you care about this will depend on how big of a Star Wars fan you are but an age-old question has now been answered by a new in canon novel. When Darth Vader hires a group of bounty hunters to track down Han Solo and his friends in The Empire Strikes Back, he singles out Boba Fett and warns him that there are to be "no disintegration." So, why exactly did the Sith Lord say that to him?
There have been a lot of fan theories over the years, including the suggestion that it was Fett who torched Luke Skywalker's aunt and uncle on Tatooine. Well, Star Wars: From A Certain Point of View features a number of short stories and in a tale set during the events of a A New Hope, we learn that it was actually some time before the events of that movie that one of Fett's jobs for Vader went wrong.
"He’s [Vader] still got a mad on over those rebel spies I crisped on Coruscant. Idiots came came at me with ion disruptors. What, they thought I wouldn’t carry a weapon accelerator? Flash, boom, three tiny ash piles. Tried to collect and Lord ‘No Disintegrations!’ refused to pay without bodies. My word’s not good enough, apparently. Reckoned I’d make up the loss by finding his droids and holding out for twice the reward."
So, we now know that Fett was also on Tatooine looking for the droids but the trail went cold when he found Owen and Beru's corpses. It's still thought that Boba Fett will get his own movie somewhere down the line (Josh Trank was originally expected to direct) so we'll no doubt learn more about his past there. Well, unless it's a sequel and the bounty hunter somehow found his way out of the Sarlaac Pit!
