Last night's crazy Halloween debauch marked the end of our annual io9 Halloween Costume Show. You guys really outdid yourselves this year. Damn! Check out the standouts from the weekend.

You posted a ton of other incredible costumes in our Flickr gallery, so go check them out. Missed out? There's always next year, plus you can keep posting your pictures on the io9 Halloween Costume Show on Flickr.

At the top, we've got a huge number of X-Men. Well done, everybody. From gildat20.
