In this related question, we learn that Vader somehow recycles his bodily waste within his suit. Which leads to another question:

Then what is the shape on the crotch for?

(Canon & EU/legends sources are acceptable)

crotch door

David Prowse (the original character actor for Darth Vader) describes this as a "protector", the implication being that it protects his vulnerable parts, such as remain of them.

KH: Were you able to keep any of the original costume you were outfitted in?

DP: When we were shooting, the costumers couldn’t get any gloves or boots to fit me – nor the codpiece. So I had to personally supply my own gloves, boots, and protector. Those three things I supplied for the Darth Vader costume, and never, ever saw them again.

Interview – David Prowse – by Kyle Harcott

Quotes from "The Complete Vader" also have much the same info, again referring to it as a codpiece

The pants (with suspenders) go on first, then the shirt and vest. The codpiece is put on next, then the chestplate with straps…. The cape should fall in pleats on either side of the belt buckle, with the light boxes arranged, one on each side of the buckle.”

Inform The Troops, The Complete Vader Has Arrived

As does the Star Wars: Technical Journal of the Imperial Forces, Vol. 2

You can see from earlier armours (in this case King Henry's from the 1500s) that the purpose of a codpiece is to accentuate the manhood as well as affording additional protection from frontal attacks against the groinal region.

    @Axelrod - That's not what that means, despite what Jilly Cooper and Jackie Collins want you to think it means :-)

    @Axelrod "thy loins". "Thine" means "yours". Commented Jun 2, 2016 at 12:17

    @Axelrod No, that says that "thine" meaning "your" is used before vowels, and "ye" is the plural form of you (the one used for addressing multiple people). Commented Jun 2, 2016 at 23:22

    @Axel Belated comment, but David is correct. As a possessive determiner, thine (and mine) is to thy (and my) as an is to a; that is, it is only used before a vowel sound. Thou/thee/thy/thine are all only singular, never used to address more than one person (except occasionally in some dialects, but that feature died out even before ye/you/your/yours took over in the singular).

The suit was designed first by Ralph McQuarrie, then refined by Oscar award winning costume designer John Mollo and production designer John Barry, as detailed here.

Here are some original drawings by Mollo:

Original sketch by John Mollo with ovoid cotch design

The design you're referring to here appear to sit just below the solar plexus, with no noticeable purpose, except perhaps to break up the large flat piece of costume.

You can see a minor resemblance to another of John Mollo's sketches of a snow trooper:

Snow trooper without embossed lines

This design does not feature any embossings, but the abdomen piece retains the similar aesthetic.

While I can't find a higher resolution picture, this seemingly earlier sketch also shows the shape, albeit lower and more prominently.

Earlier sketch

No lines appear to point it it however, and no purpose seems to be reveal either, beyond protection perhaps. This would have been before Vader's character had been finalized, and his history decided. The design was probably toned down, but remained for aesthetic reasons.

It's not uncommon for sci-fi armour to protect this region of the body, one example is from Judge Dredd:

Judge Dredd in not much more than a leotard, codpiece and pauldrons.

This is far more obvious, albeit still practical.

    Nothing about Dredd's outfit is practical...

  • @amadeus9 I read referring to the protection it provides.

  • Is Dredd's really bigger than Vader's? Commented Jun 7, 2016 at 0:13

Assuming that Darth Vader still needs to eat (does not live off of the power of the force) it would be impossible for him to receive nutrients intravenously (after a while your stomach gets bored and eats itself, not good). And if he does indeed eat, he would need some way to dispose of the bodily fluids easily and cleanly. He obviously cannot take his suit off as that would kill him, because his suit maintains his life. SO think of it as easy access to his waste bag... Edit: apparently I was wrong, did not know that.... Thanks for the info.


His entire suit is pinstriped. Why leave out my mom's most favorite piece the most important part?
