WonderCon returned to the Anaheim Convention Center yesterday, bringing with it throngs of comic, fantasy and sci-fi enthusiasts decked out as their favorite characters in what is known as “cosplay.”

The popular fan show is one of the largest comic conventions on the West Coast, famous for attendees cosplaying as their favorite superheroes, sci-fi, fantasy or anime characters, will be at the Anaheim Convention Center through Sunday, March 26. Attendees come from all over the world.

WonderCon began in the Bay Area in 1987, before relocating to the Anaheim Convention Center, where is has been since (with the exception of a 2016 interregnum in Los Angeles).

The show features an expansive exhibit hall and comics, movie and television sneak peeks. Attendees line up throughout the weekend for signings by renowned comic artists, and the show culminates Saturday evening with a costume competition known as The Masquerade.
