The Immortal Hulk takes on an extra powered Absorbing Man, who can now absorb gamma radiation as well courtesy of a shadow group within the US army, hellbent on taking down the Hulk. The fight ends when the Absorbing Man somehow absorbs a demon, the One-Below-All, away from the Immortal Hulk.
I love the Hulk’s “what the fuck is this” expression in the last panel.
