Hulk and Rulk vs Hal Jordan and Flash
Debatable whether or not Hulk and Rulk could even work together, but how would they fare against one of DC's best duos?
Two scenarios
1) no holds barred (meaning BFR is on and any environmental objects such as cities, oceans, the sun, etc. are usable)
2) No BFR in a war-world type setting, 200 x 200 arena with a flat floor and no objects
I would personally think in scenario one Hal Jordan gives team 2 the clear advantage, but in 2 it could change.
