See Spoiler tag (if you read Avengers Academy #3. I don't know if it warrants a spoiler tag, so I did it anyway)
Location: A training arena. It's 100 ft wide and 100 ft long.
They start 10 ft apart. No prep. They know nothing about each other prior to the fight.
Round 1: Armed with their standard gear.
Round 2: Unarmed.
So, who wins?
