Fight takes place in a open field. Fight to the Death. Who wins?
Is this pre new fifty two Midnighter? It makes a pretty big difference.
General rule of thumb is to go with the most current unless otherwise stated.
That being said, pre-52 would probably take it due to doors. Post-52, if he doesn't have doors, then I would tentatively give it to Warmachine until proven otherwise.
War machine can fly, which gives him a pretty much unstoppable advantage. Middy doesn't have the damage output to get through the suit, anyway. Eventually War Machine can deal enough damage to put Midnighter down.
Hellstrike thought flight and ranged attacks gave him an unstoppable advantage too, but Midnighter still beat him even with his combat computer off.
@Wyldsong: I'd be one to sometimes choose the more established version of a character. But that's just me.
No he did not, though given the relative newness of the current Midnighter and his vague abilities, I assume the Wildstorm Midnighter in threads where it's not stated otherwise and he would be allowed Doors. (Though the newer Midnighter might suss out a weakness he could take advantage of from a distance.)
And I'll just cover the typical response now. Midnighter doesn't need that exact situation to be happening to distract someone. Given the range of weapons and explosives he carries, distracting someone doesn't require nearby softcore porn. Also, War Machine's armor is durable, but again Midnighter carries serious explosives and is not a stranger to punching out of his weight class. Also also, just to be clear, my comment was less "Midnighter wins" and more "Flight is not an unstoppable advantage like people think it is."
