There was such a mind boggling onslaught of TPM merchasdise, I’m surprised there wasn’t one. Jar Jar made it into bathroom accessories, but I guess nobody wanted a sith lord toothbrush holder or soap dispenser?
Unless crime syndicates are secretly giving the Empire a cut to keep out of their affairs, I can’t see Vader having anything to do with them.

Oh sure in 1999, I just mean like now. Today there are still new Vader and R2D2 things going strong. Household names that people know when they might not have seen a single movie.

As for the cameo I mean I guess it doesn’t have to make sense. Qi’ra can just be the new secret apprentice. Or the new Emporer’s Hand. Or something else dumb.
