>>93357532In all fairness, that Hulk vs Bats battle was late-70s, early-80s, a time when the Hulk's power level had not escalated to the crazy levels it became later on.
And the story clearly stated the kick did no damage itself, it was intended to cause a reflex gasp of breath at a time when Bats had tossed down a bat-sleepgas-capsule. Hulk breathed out but wasn't hurt, when he breathed back in... he sucked in a room full of sleep gas and toppled over.
On one side, sleep gas probably wouldn't even bother the current Hulks, but on the other side I give Hulk credit for actually realizing he needed to hold his breath. That knockout gas stunt had been used on him a half-dozen times before the Hulk vs Bats comic and the writer actually had the sense to let Hulk learn from those recent incidents.
