(CNN) -- 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.
From Iron Man to Wonder Woman, to the Joker and the tried and true Klingon costume, we've gathered examples of these characters from Comic-Cons, past and present. Take a look at the gallery above, then share in the comments below which ones you prefer among each slide in the gallery.
We'll continue to update the gallery throughout SDCC 2014 with new photos of competing costumes. Come back Saturday and Sunday to see new photos featured in the gallery and share which looks you liked the best.
Good luck and may the best costume win!
