Incredible Hulk #23

The grey Hulk dominates this 2001 cover — massive, snarling, and straining against restraining cables while two eerie, skeletal-looking dogs circle at his feet amid a haze of dust and debris. It's a striking image from cover artist Kyle Hotz, whose angular, gritty linework makes the Hulk feel genuinely menacing rather than simply powerful. With Paul Jenkins writing and Eric Powell inking the interiors, Incredible Hulk #23 delivers the kind of moody, street-level tension that made this era of the title so compelling.
