The rumors continue to swirl around the next Star Wars film, Rogue One, which arrives in December of this year.
A new rumor stemming from Making Star Wars suggests a few specific details about Whitaker's role. First of all, the rumor makes claims of the character using a cane because he has only one leg, having lost the other in battle and replacing it with a "robot leg." He is a veteran of "some battles," though there is nothing to say whether he lost the leg fighting in the Clone Wars or against the Empire.
The rumor takes into account that Whitaker's character has a differentiated code name from the rest of the rebels in the movie, so he is likely one of the good guys, at least for Rogue One, but possibly a bounty hunter of some form.
Finally, the character wears a cape and has quite an extravagant wardrobe. He would fit right in on Takodana, Maz Kanata's home.
