I saw it at the Dragon Con in Atlanta right before the costume parade. I asked the person wearing it if they would let me take a photo and they were kind enough to pose for me.Which proves that MODOK fans are always down for a good photo opportunity. Also it shows this beloved Mental organism to be extremely photogenic.
[EDIT: Big thanks to Contagious Media for identifying the creator of this awesome costume, a designer who goes by the name of Midwest MacGyver. I did do a search for the appearance of the costume so I could credit the designer and found many pictures of it, but couldn't link it to a specific creator. --B]
