The one where Venom joins up with Punisher. When we last saw Venom, he decided to be a good guy--or, more precisely, a “better” guy than he had been because he’ll only eat bad guys.
In this case, he eats a street gang that Punisher also wants to take out of commission.
But first they fight (above), because, of course they do. And they fight again…
After they fight a bit more, they team up.
I mean, sure, a little more happens than that, but that’s the gist of it.
