It looks like one of the characters from “Rogue One: A Star Wars Story” will be making the crossover from movie to animated television when Saw Gerrera joins the cast of “Star Wars Rebels: Season 3”!
According to Making Star Wars:
Rebels Reactions Podcast discovered a pretty awesome Star Wars Rebels poster at Toys R Us, the poster reveals for the first time, Rebels Rogue One connection. Saw Gerrera is featured on the poster. This is the first time we see Saw in Star Wars Rebels.
I for one am very excited about this. Mon Mothma tells Jyn in Rogue One that Saw was a problem for the Rebellion and that’s why they weren’t working together anymore, so I would imagine we will see that falling out in Rebels. We will see Saw in the second half of Rebels Season 3 where he will lead a investigation on Geonosis.
