yeah I actually thought the batman hulk thing was pretty cool, Batman dropped a knock out gas grenade and kicked hulk at the perfect moment with the perfect surgical presicion that caused hulk to gasp for a slight bit of air thus inhaling the KO gas, thus knocking his ass out. It was cool.
but anyway's new venom is rebonded with eddie brock and another venom, which somewhat gained it's own sentience in a way (long....confusing story). The end result was a venom that was the size of a small house, so basically venom x2.......Also the new venom is nowhere near as fragile to fire and sonics has he used to be.
i've never known venom to get KOed via physical force so please do tell me where that occured.
And the new venom did need a host body, but only as a vesil to supress it's appetite, and you're right physical assaults on that venom incarnation are about as effective as fighting air.
