Geeks across fandoms save their most inventive cosplay for the biggest local comic event of the year, Emerald City Comic Con. The four-day event is filled to the brim with panels, meetups, special events, fun parties, and tons and tons of guests hanging out in the artist alley (this year's headliners include Mark Ruffalo, Karen Gillan, Levar Burton, and Michael J. Fox). In addition to the main events at the Convention Center, this year's newest addition is Pop Asia, a buzzy anime, manga, and K-pop event at the Sheraton Hotel.
