Ever since his debut in Empire, Boba Fett has become one of the most well loved characters in the Star Wars universe which is quite impressive for someone who utterly fails at his job:
Of course, this begs the question, is Jango any better? If we use Episode II as evidence, Jango kind of goes out like a bitch. We don’t see him do any kind of bounty hunting anything. Sure, he serves as the genetic template for all the clone troopers which is actually kind of badass. But we see no evidence of bounty collecting prowess in the film.
However, I don’t think it’s totally fair to just use the movies for evidence. After all, the Star Wars films are really the story of the Skywalkers. The Fetts are side characters. I feel like Boba serves more of a purpose in the films than Jango. It’s because of Boba that we have to rescue Han from Jaba. Jango’s just kind of there. And then he’s not. And that’s fine because it’s not about the Fetts. It’s about the Skywalkers.
I don’t think the films are a good representation of Fett skill sets. There’s a reason Jango was chosen as a genetic template. There’s a reason that Darth called Boba. These facts are undeniable in the context of the films. That’s gotta mean something. So even though we see very little on screen evidence of bounty hunting skill, the Fetts are certainly badasses.
