Sunny Joe encounters The Midnighter, and due to a misunderstanding they end up fighting to the death. This is Sunny Joe as of Legacy: Homecoming, and The Midnighter as he was prior to DC's absorption of Wildstorm.
Further stipulations include the absence of Door or any variations of it. I want this to be an actual fight, and not a BFR contest.
The fight happens somewhere near the Arizona Reservation. The victory condition is either death or incapacitation of the enemy.
If anyone is unfamiliar with Sunny Joe I can provide feats.
