Speaking of the standalone sequel Episode VII movie, in that storyline the main male protagonist loses a leg in a duel with the Dark Lord at the film’s end. However, he survives and wins with the help of his girlfriend, Kira Starkiller/ Skywalker.
This is alluded to in Marvel’s recent Darth Vader comics, where Vader’s suit is injured in three areas: the eye of his helmet, his left arm, and his left leg.
The broken eyepiece reveals the eye of Anakin Skywalker, but his suit’s left arm being torn off is a reference to Luke losing his left arm at the elbow in early drafts of The Empire Strikes Back. (To make sure we get the reference, Vader retains his glove, but it has a hole on the back, where Luke gets shot in the hand in ROTJ.)
And the left leg being lost entirely, droid limb and all, is a reference to this alternate Episode VII. (The comic has a few other cerebral in-jokes as well, such as a planet Vader visits having a mountain called “Passvaal”, as in “Parsifal”, and shaped like the Mount of Purgatory from the Divine Comedy.)
I mention this here because according to George Lucas, limb injuries are sublimated castration scenes. You’re welcome.
