501st 

Also known as "Vader's Fist". The 501st Legion is the world's largest Star Wars costuming organization whose aims are to promote the Star Wars brand, celebrate fandom and contribute to the community through charity and volunteer work.

Dang! The 501st helped raise more than $3.4 million in charity last year by dressing up like Stormtroopers!
