It is amazing how the disappearance of all a hero's villains could go unnoticed. The thing is, unless they were in a prison or known location, villains tend to hide. Only the most paranoid hero would be worried with the vanishing.
Which was why this heroes Rogue's Gallery vanishing was not noticed even as certain people, certain sexy female people, were getting boxes of clothing they didn't order. Boxes of costumes they just had to try out. Clothing with the essences of those missing villains.
Which would render this hero surprised as his villains seemed to be changing....
