Cosplay at Comic-Con: Who wore it best?

Story highlights

The annual San Diego Comic-Con, mecca of all things pop culture, began on Wednesday night and runs through Sunday, July 27. The massive convention -- known for giving fans a first look at the latest "geek-friendly" TV, film and of course, comics -- is also a major gathering for cosplayers (that is, fans who wear costumes of their favorite characters).

Cosplay is an integral part of Comic-Con and similar conventions, with countless fans creating elaborate costumes to transform into superhero, comic book, video game, television or movie characters. And while the costumes are varied, there are certainly some favorite characters for cosplayers, as evidenced by photos we've seen of them over the years on CNN iReport.
