Both characters are in character but serious, and have morals.
No knowledge on the other fighter
No scaling Iron Man to ANY past armours, I see you there with the scans
Clark is post JL
Battle takes place in New York while 200 Sentinels invade
Both characters start around about the end of two sides of a street
BONUS- Iron Man gets all of his armours (apart from Bleeding Edge, Hulkbuster, Thorbuster, that thing he used in Fear Itself, Superior) but Clark gets the JL, Mysterio, and the original MCU Avengers to assist him. Who wins then?
