Boba Fett to show up in Rebels?
Wouldn't it be cool to see Boba Fett again? Especially since he'd be about 27 years old right about now and making quite the reputation for himself. And hell, with Boba being a young man, they could totally have the actor who plays Rex, also voice the legendary bounty hunter.
Besides, Boba and Rex are practically twin brothers ;)
Imagine if Thrawn decides to think outside the box and hire an outside source to do some recon for him, like Vader did in TESB.
Besides, Boba Fett vs. Sabine, wouldn't that be an awesome fight?
