Lobot
If Cassian Andor can get his own show then why can’t Lobot? Lobot didn’t have a lot of screen time but was a curious character for the brief time he did help our heroes out in The Empire Strikes Back.
The guy is the epitome of bland. With his gray jumpsuit and flesh-colored billowing sleeves he pretty much blends into the background of the Cloud City set. There are some aspects about him though that are interesting and mysterious.
What exactly is he? He looks like a human but also has that weird computerized headband that apparently Lando can communicate through using his wrist band. So does that make him a droid?
One other thing to wonder is how a guy who doesn’t speak and looks like a set of drapes get to become friends with one of the most outspoken and charismatic characters in the galaxy? That is something that could be worth exploring, and a show I’d watch before seeing the adventures of Cassian Andor, pre-Rogue One.
