superheroes baffled by world's largest pollen grain

Cut-paper collage postcard created for the Kollage Kit theme: "Guinness Book of World Records."

Pollen grain from a gingerbush. I'm afraid I can't identify all the superheroes. Yes, I know there are two versions of the Flash. My favorite one is the guy in the upper left: what a snazzy costume! Too bad his hair's on fire. =laugh=

Addendum: Someone helped me out with the name of the guy in the upper left. He's Firestorm, the Nuclear Man.
