Darth Nihilus Costume Guide

Darth Nihilus KOTOR costume for cosplay and halloween

In Star Wars canon, Darth Nihilus reigned as a Dark Lord of the Sith during the Jedi Civil War. Eerie, ominous and a bit scary, Darth Nihilus has had a terrible past and was brought out of it by none other than Darth Traya, who taught him how to become one of three Dark Lords. Unfortunately for her, Nihilus turned against her and took her energy later on.

This Sith Lord is one of the creepiest Star Wars characters, making him a great choice for any Halloween party or cosplay convention if you’re a die-hard Star Wars fan.

See below to learn how to make your own DIY Darth Nihilus costume for cosplay or Halloween.

How to Dress Like Darth Nihilus from Knights of the Old Republic


Beneath a hooded black cloak which covers most of his head, Darth Nihilus’s face is covered by a white mask which obscures his features. Adorned with red and gray markings, this makes the character look all the more disturbing and mysterious.

To cover up any extra parts of your face not hidden by the mask, wear a black ski mask or black Halloween face makeup underneath to recreate the enigmatic style.


Darth Nihilus wears a long black hooded cloak which covers most of his body. You can wear any black clothing you’d like underneath, and for the cloak, search Halloween stores and costume shops for one that resembles Nihilus’s.

To find black clothing to wear underneath, check out online retail websites or shopping malls for those extra supplies. A good choice for a colder night would be a long-sleeved black shirt, black socks and a pair of black jeans or stretch pants. You can also wear a black fabric belt to keep the cloak fashioned in place like Nihilus’s.


Darth Nihilus wears shiny black gloves, black boots, and like any powerful Sith Lord, he wields a bright red lightsaber.

You can buy gloves from most retail websites and accessories shops. Check out shoe shops or retail websites for the boots, and for Nihilus’s bright red lightsaber, visit a costume website or Halloween store to see what you can dig up.

For an extra bit of authenticity, search for a lightsaber with built in lights or glow-in-the-dark qualities so you can get the same lit-up futuristic look as the one Nihilus uses.

If you want an extra challenge for your costume, round up your friends and family to dress up as other Star Wars characters so you can bring the force to your next Halloween scene or upcoming cosplay event!
