Punisher and Deadpool are probably the most crazy (in different ways) gun wielding hero's in the Marvel Universe, but in a gun fight Deadpool has an un-fair advantage as he can heal rapidly, so if he not have this ability and hey had their skill who would win??
Both get two pistols and one assault rifle ---- I am not good with guns so you pick, but what ever you pick other character gets the same. Punisher has no Microchip to help he is on his own.
Fight takes place in an unpolluted NYC.
Bloodlust is on!!!
