This one is simple. Takes place in Metropolis. These two are more pissed at each other than Stark and Thor were in the forest in Avengers. Hal's will is indomitable.
Four Rounds:
1. Comic Superman vs. Comic Green Lantern
2. "Man of Steel" Superman vs. Movie Green Lantern
3. Comic Superman vs. Movie Green Lantern
4. "Man of Steel" Superman vs. Comic Green Lantern
I was thinking that, because Hal can create whatever he imagines, he potentially could just create an army of green Supermen and just sit back with some lemonade or sweet iced tea, and watch while they take care of the real Superman.
He isn't powerful enough to hold the constructs against Superman. He can make constructs in image of superman but they would lack the power of superman.
