Fear Itself: The Deep #4 (of 4) (2011)

Namor, Doctor Strange, Loa, She-Hulk & The Silver Surfer giant have battled barbarian hordes, giant monsters, and demonically-
possessed sea creatures. They’ve faced Tyrak the Terrible, Aradnea the Sorceress, and the hideously-mutated Tiger Shark. But their greatest threat still awaits—the Worthy who has already beaten the Sub-Mariner and single-handedly ravaged New Atlantis. Would-be conqueror Attuma has become 
Nerkkod, Breaker of Oceans, and he intends to drown the
entire world in a wave of fear! Even if Namor’s courage and resolve return to him, he’s no match for the fury of the
 Serpent’s chosen!
