Welcome to the Underworld Detachment, the home to the criminal element of the Star Wars Universe. Here you will find pirates, gangsters, henchmen, thieves, smugglers, thugs, and… of course… scum and villainy!

We strive to create accurate and quality costumes based on characters from Star Wars stories, including movies, animated and live action shows, etc. The references are as vast as the character possibilities. The majority of characters within our ranks fall under the ‘denizen’ category and were featured on the big screen, but we look forward to the expansion of our known narrative with recent and upcoming television series. Our goal is to serve as a center of knowledge and experience in these and future costumes.

Underworld was formed in 2018, and it was the first new Detachment of the 501st Legion in 11 years: the creation of this new Detachment was over two years in the making.
Characters were moved from the “Unaffiliated Detachment”, and some were transferred from the Krayt Clan Detachment. Out of the 12,000+ active members of the 501st Legion – there were under 40 members for this Detachment when it was founded, and a total of 19 costumes. We now celebrate a roster of over 40 unique characters with over 450 members in the Detachment globally. 

Our community is filled with passionate and skilled members, as well as some of the most unique costumes found within the Legion. As we continue to consolidate past research and experiences in our forums, we look forward to assisting you with your 501st Legion and costume journey.

May the Force be with You,
