The Canberra-based squad is part of a worldwide Star Wars costuming organisation, the 501st Legion, that spends time raising money for charity.

Black Tower Squad commander Mick Ferris said the volunteer-based group builds film-accurate costumes for costumed charity and volunteer work as well as Star Wars-related events.

"The 501st Legion is an international fan-based organisation dedicated to the construction and wearing of screen-accurate replicas of Imperial Stormtrooper armor, Sith Lords, Clone Troopers, bounty hunters, and other villains from the Star Wars universe," he said.

The organisation has over 10,000 members worldwide, with around 40 members in Canberra.

The Black Tower Squad named itself after Canberra's Black Mountain and Telstra Tower. They 'kit-up' for local charity events such as the MS Walk and Fun Run and Relay for Life, as well as smaller community events.

They've even made appearances at private parties and weddings - including one Canberra wedding where the bride walked down the aisle to Darth Vader's Imperial March - and the Special Kids Christmas and Dream night at Taronga Zoo in Sydney.

Mr Ferris said while the Black Tower Squad doesn't charge for appearances at events, donations to the Black Dog Institute are appreciated.

He said although the group is not officially connected with the Walt Disney Company or Lucasfilm LLC, the 501st Legion is Lucasfilm's preferred costuming organisation.

If you'd love to delight Canberra kids by turning up to events dressed as Kylo Ren or any other Star Wars villian, The Black Tower squad will be running a recruitment drive at the Connect and Participate Exhibition in Canberra on Saturday, March 24.
