Heroes Con has become a favorite summer tradition of mine. The convention is one of the oldest and largest independent comic book conventions in the United States. It's held the weekend of Fathers Day, so for us it's a perfect family nerd out weekend.
I'm a sucker for Star Wars cosplay at any convention I go to. The Darth Bane in his Orbalisk Armor (top right hand picture) impressed me because he said he sculpted all the little creatures on his armor.
General Grievous's armor was extremely clever due to the fact that the person that was operating the costume was tucked away unseen in the back of the cloak.
