VIXX revealed pictures for their upcoming comeback with 'Error'!  It looks like the boys are ready for Halloween as they're dressed up like robots in human form as bits of their metallic interior show through their skin.

While it is definitely an eerie and mysterious concept, the boys pull it off with effortless charm--not to mention, it's hard to not appreciate Hongbin's spectacular abs!

Their second mini-album will be out on October 14!
