Or is he Both? (Immortal Hulk, Volume 1)

THE RETURN OF BRUCE BANNER!

You know Bruce Banner. He's quiet, calm, never complains. He's a man who believes he can use the darkest elements of his personality to do good in the world. If someone were to shoot him in the head... All he'd do is die. But the horror lives deeper. A horror that refuses to die.

When night falls something other than the man gets up again.

The horror is the Immortal Hulk.
