As the terror plague in Fear Itself grips the surface world, the Serpent's reach does not exclude the world beneath the waves, as proven in Fear Itself: The Deep, a new miniseries from writer Cullen Bunn and artist Lee Garbett.
Namor's most persistent enemy is Attuma, and the Serpent has deemed him one of his Worthy, and thus the warlord is wielding a mighty hammer and has vastly increased his power level. This forces Namor to do something he dislikes – ask for help. It comes in the form of the young mutant Loa, as well as the venerable Dr. Strange and "the Savage She-Hulk." For those of you not up on the massive Hulk proliferation in recent years, this will likely mean Lyra, Bruce Banner's genetic daughter from an alternate future ruled by women like Thundra, her mother. This is through process of elimination, since the Red She-Hulk is in the main Fear Itself book dealing with Hammer Hulk, and the original Sensational She-Hulk is hanging out with Howard the Duck in Fear Itself: Fearsome Four.
