Lol. Batman wins.
1. There are innocents scurrying about. Hulk ALWAYS holds back, even WBH held back until he was in the Dark Dimension, and he knew Betty was his equal AND that Bi Beast etc would always regenerate endlessly.
2. He does what he did to Domesday, and splits the Hulk over 4 or 5 JLA teleporters. At any one time, no more than 20%/25% of the Hulk would be complete. Not using BFR.
