Gandalf the Fuchsia, Pet-o-ween and Krang, all on io9's Costume Show

Happy Halloween week! Our annual Halloween Costume Show is back for another round, and it's scary just how good you all look this year. Take a peek at the best of the best of what we saw last week — and then show us what you're planning on wearing this year.

Put up pictures (of yourself only please!) in the comments below along with a note about who your costume portrays and how you made it. We'll be showing off the best one more time next week. And, in the meantime, check out all the ways that your fellow commenters (and their pets!) are keeping the spirit of Halloween alive and kicking this year.
