The desert floor cracks like old pottery the moment they collide. Hulk drives a fist into Superman's chest that would flatten a mountain range, and the Man of Steel *moves* — skidding back through a ridge, raising a cloud of red dust three miles wide. Superman answers from the air, keeping distance, circling on thermals, forcing Banner's monster to chase a target that never stays still. Every time Hulk lunges, Superman is already somewhere else, heat vision scoring across green shoulders, flight keeping the fight on Superman's terms. Neither of them is running. Neither of them *can* lose this.
That is exactly the problem. Superman hammers Hulk with everything — speed blitz combinations that blur the air into white streaks, solar-charged haymakers that would split tectonic plates, sustained heat vision that carves glowing channels across jade skin. And Hulk just *takes it*. The pain tolerance is something unnatural, something that lives below thought, below instinct — an abnormal relationship with damage that turns every strike Superman lands into fuel. Hulk heals between exchanges. He gets back up. His roar shakes the dust off cliff faces twenty miles away. "HULK DOESN'T STOP." He means it biologically.
Superman knows. He can feel it as the hours grind forward — Hulk's regeneration cycling faster than the damage accumulates, the green colossus absorbing punishment that would have ended any other fight long ago. Superman's own invulnerability holds. His solar reserves remain deep. But Hulk's body is a machine built specifically for outlasting punishment, and the longer this goes, the more clearly that truth asserts itself. Every minute Hulk stands, every blow he shrugs back to vertical, the arithmetic tilts. You cannot contain him. You cannot put him down permanently with conventional force. He is simply *harder* to end.
Eventually, Superman stops trying to finish it. Not defeat — endurance. He pulls higher into the atmosphere, letting the fight stretch across a timeline where attrition decides everything. Hulk stands in the crater below, chest heaving, grinning with something that isn't quite human satisfaction. Superman is still here. But Hulk was never going anywhere. When the dust finally settles over a landscape that looks like the aftermath of a geological event, it is the green titan who remains standing in the rubble — impossible to contain, impossible to kill, outlasting everything thrown at him through sheer biological stubbornness. Superman fought brilliantly. Hulk simply refused to stop existing.
WINNER: Base Hulk REASON: Hulk's regeneration and abnormal damage absorption make him categorically harder to put down over time, outlasting Superman in a war of attrition neither can decisively end by conventional force.
