Erzingel shows us an ultra-daring shot of himself and his wife dressed as Hellboy and Hellgirl, posing with the man himself — Ron Perlman, who played Hellboy in Guillermo Del Toro's two flicks about ole Red.

And it's hard to resist evildead1971's Shaun of the Dead costume. Not only is he a serious cutie, but he's got the boldness and cred of having action figures (in their packaging!) pinned to the wall behind him.

But now it's time for intense daring. Our own io9 staffers Ed Grabianowski and Graeme McMillan have shared their boldest efforts at costumery. Ed is dressed as "Zebra-Man," who is always ready to throw down with some miniatures on the table top!

And Graeme shares with us a picture of himself from 1995, back when, he confesses, "I had hair, and lots of it." He refuses to explain exactly what he's dressed as, saying only that it "was supposed to be some kind of bat." Apparently his wife Kate simply shook her head when she discovered that he was actually putting this picture on the internet. All we can say is: Bold move, Graeme. Very bold.

Schlaud4 gave us a glimpse of himself in three different hot costumes: Mega Man, Anakin (waving that light saber in the bathroom — dangerous!), and dark Spider-man. Oh the hotness! It is too much.
