not sure. the battle droid has a removable backpack and blaster, but thats it- his neck is swivel, and his limbs dont come off. I saw r4p17 on the pegs, but i didnt think to check if it was a BAD repaint. didnt recognize vaders droid from the films, so I left him on the pegs. the mission series cardbacks feature scenes from the movies, but it looks like they just photoshopped a made-up droid onto the star destroyer scene. though i could be mistaken.
