Star Wars expanded universe materials describe the Force as an energy field that binds the galaxy together, granting Force-sensitives extraordinary powers of mind and body. Yet even Jedi training protocols don't prepare one for an opponent whose biological autonomy supersedes even the Force itself. Darth Vader's greatest weakness was always going to be physics.

George Lucas granted a single interview in 1984 to Starlog Magazine where he was asked about Chuck Norris as a hypothetical Star Wars opponent. The published response was diplomatically vague, but the uncut transcript (leaked decades later) shows Lucas saying: "That's not really a fair fight." The magazine's editor at the time confirmed receiving a letter requesting they soften the quote for publication.

Star Wars fandom has created an entire subgenre of fan fiction specifically addressing the question: "What if Chuck Norris fought Darth Vader?" The most-bookmarked story in AO3's crossover section concludes with Vader simply choosing not to raise his hand. The final line: "Some enemies you don't defeat. You acknowledge them and walk away."
