"Deal," Superman says a little too quickly, and Supergirl shoots him a glare.

"What, no, you can't..." she stammers.

Superman smiles at her in a slightly cocky manner. "Hey, don't worry, I'm the man of steel."

Supergirl actually manages to roll her eyes, forgetting the situation for half a second. "It's only a costume!"

Before she can say anything more, Captain America has set his shield down on a nearby wall, resting his elbow on one side, Superman already moving in to position.

Fear begins to trickle down Supergirl's back. Surely they can't really be going ahead with this. It's at that point she notices the small crowd gathering around them, all wanting to see two comic book icons in a classic test of strenght.

Kneeling either side of the shield, Captain America and Superman lock hands, and the contest is suddenly on.
