Star Wars Die-Cast Elite Series C2-B5

This is one of my first two die-cast elite series figures, C2-B5. My sister got this for me on her recent trip to Disneyland, and I seriously can't get over how much I like this figure. With the exception of the little projectors on his dome, everything else about this figure is made of die-cast metal, making it a little bit heavier than your average figure. It's still a really nice figure, though, and I love the paintwork and detail that went into it. Seriously, just beautiful, man.
Now, he is from the Rogue One line, so I think it's safe to say we'll see him in the movie. The back of the box he came in didn't give any information about him, just a basic description of what an astromech droid is, so I don't know if he's going to have any sort of actual role in the film or if he's just going to be one of those droids you see in the background of certain shots. I also can't tell you guys if he's a Rebel or Imperial droid. My guess is that he might be an imperial droid, since the Empire often tends to use either a black and silver, or a black and orange color scheme for their droids.
