Hundreds of Star Wars cosplayers from seven countries took part in a parade in Mexico City.

The event was organised by the Mexican Garrison of the 501st Legion, which describes themselves as a non-profit organization made to amaze fans and bring more people into their fandom through its authentic-looking costumes.

Most of the participants dressed as the side characters of the saga, that kicked off in the 1970's as a Sci-Fi space opera.

Only a few were selected to perform as the main characters, Luke Skywalker, Princess Leia and a not so intimidating version of Darth Vader.

Stormtroopers opened the way to Darth Vader, escorted by Imperial pilots in the parade.
