Han Solo vs. The Punisher
Crossed wires. A spice shipment gone wrong, and Han Solo is on earth. It doesn't take long for him to step on The Punisher's toes, and pretty soon the two end up in a battle....
Note - Han doesn't have the Falcon or Chewie with him. Just his wits, and a number of conveniently placed weapons. Just like the Punisher.... who wins?
