The Immortal Hulk Omnibus - Mark Waid, Jim Zub, Al Ewing

Horror has a name. You'd never notice the man. He doesn't like to be noticed. He's quiet. Calm. If someone were to shoot him in the head... all he'd do is die. Until night falls - and someone else gets up again. The man's name is Banner. The horror is the Immortal Hulk. And trouble has a way of following them both. As Bruce Banner struggles to control the undying monster within, he finds himself hunted by his old friends and allies. But there are more sinister forces at work. Something terrible has infected Banner. A dark infection with unspeakable plans for humanity.
