Chev Chelios vs Bryan Mills
Chev Chelios, from the Crank films
VS
Bryan Mills, from the Taken films
They are fighting in a large mall in New York City. They are fighting to the death. They are both in character. They start off unarmed, but they can use whatever they find, steal or otherwise obtain in any way they can. They know nothing of each other prior to the fight. There are lots of civilians around, and they may call the police.
