Rogue One: A Star Wars Story provided a fantastic new battle sequence for Vader, although now it appears that he very nearly appeared in James Gunn’s original Guardians of the Galaxy movie.
There’s few fictional characters quite as massively popular as Star Wars’ Darth Vader.
And while he wouldn’t have shown up to tell Peter Quill that was his father (they saved that for Kurt Russell), Star-Lord originally had a Darth Vader action figure in his belongings.
The conflicted villain is the mascot of the franchise as a whole, with the fandom obsessed with every lightsaber swing and strained breath the the Sith Lord takes.
