This past weekend was Anime Expo, the ginormous celebration of all things anime, and the sheer amount of lovely cosplay will melt your brain. Check out a gallery below — but also please tell us: What character or concept makes for the best cosplay in the universe?

Please include photos of the greatest character or clever concept that you've seen done as cosplay, or that you've cosplayed as yourself.

The photos below come from Davann Srey, our favorite cosplay photographer, and you can see tons more on Davann's Flickr stream.
