Talked about this in the Elektra and Punisher thread, thought this would be a better debate.
Here's the situation:
The U.S. government has found out that Bruce Wayne is spying on them and they have sent in Snake-Eyes and Storm Shadow to gather intel. Meanwhile SHIELD has also noticed Bruce's prying eyes and seek to learn more about the information. With their usual agents and assets spread thin they decide to call in Elektra and Daredevil to get the job done. Meeting each other within Wayne Manor they mistake the others for enemies and begin a no holds barred fight to the death (or KO). They begin 50 feet apart on opposite sides of the room pictured below. The boundaries are the Manor itself. If anyone leaves the building they are disqualified from the battle. Naturally all combatants are in character.
