Mystery Mando
One of the Mandalorians attacking on Nevarro uses a rope to trap and trip his enemy. We can’t see very clearly who this is but the rope, targeting system on the helmet and rocket jet pack all scream “Boba Fett.” However, the colors of the armor tell another story. So, we’re guessing it’s not him, considering the shoulder pauldron that is very not Boba but, maybe, the trailer specifically changed that? We don’t think so but, it’s possible.
