Incredible Hulk #19

This part-six entry in "The Dogs of War" brings one of the most viscerally unsettling covers of 2000: Kyle Hotz's art depicts a green Hulk and a grey Hulk locked in a brutal, almost nightmarish clash, their snarling, distorted faces crammed together as fists fly against a lurid pink haze — the "Psyche-Out!" cover text suggesting a battle as much psychological as physical. Paul Jenkins scripts alongside artists Ron Garney and inker Sal Buscema, a creative team that had been delivering consistently gripping Hulk storytelling throughout this run. If you've been following the arc, this penultimate chapter looks like exactly the kind of escalating confrontation that demands your full attention.
