Over Labor Day weekend, more than 75 cosplayers at Dragon Con became Internet freedom heroes for real, using their fantastic costumes to highlight how anonymity and privacy are crucial to free expression.

It was all part of Project Secret Identity, a cross-fandom activism campaign organized by EFF, io9, the Southeastern Browncoats, the Harry Potter Alliance, the Baker Street Babes, Wattpad and the Organization for Transformative Works. Even avatars from virtual worlds organized a march online in solidarity.

Choosing just 20 of the best images was a superhuman task in itself, so hop over to ProjectSecretIdentity.org to see the full selection.
