This is before Killmonger takes the heart shaped herb and gets the vibranium suit.
Scenario one: Both men are on opposite ends of a dimly lit warehouse. Each gets an AK-47, a Desert Eagle pistol, three grenades, and a Ka-Bar knife.
Scenario two: Same as scenario one, but Punisher has to escort Karen Page to the exit on the other side of the warehouse. Killmonger wins if Karen dies.
Scenario three: Same as scenario one, but Killmonger has to escort Linda to the exit on the other side of the warehouse. Punisher wins if Linda dies. Assume Killmonger actually wants Linda to live.
Scenario four: Hand to hand battle at the Wakanda waterfall. Both are armed with a shield and vibranium knife.
