In Fantastic Four issue #299, 1987, She-Hulk takes on The Thing.
After getting into an argument with The Human Torch, The Thing decides to leave to get some fresh air. His replacement in the Fantastic Four, She-Hulk, calls out to him as he’s getting in a taxi, but he ignores her and goes on his way.
After learning about the argument with The Human Torch, She-Hulk decides to find The Thing and lighten up his mood… by throwing him through a brick wall.
Both take turns “clobberin'” each other until the Thing realizes it was all a ploy to help demolish some buildings, helping out the local Atimor Demolition Company. The fight ends as a draw and they both cool off by getting some lemonade (only in the 1980s!).
