Fear Itself: The Deep (2011 series) #3

Lyra, the Savage She-Hulk, has been dragged beneath the ocean’s surface by Atlanteans possessed by Undying Ones, led by a two-headed Tiger Shark. Then she discovers she can breathe underwater, courtesy of Doctor Strange who has magically provided the same ability for teammate Loa and himself (Namor and Silver Surfer don’t need the help there). The new Defenders realize they are vastly outnumbered and to exorcise them, Strange would need the magical artifact used to summon them if they would spare the mortal hosts. Namor fears hurting his people, despite their possession, and their cries feed into his guilt over failing to protect them. Tiger Shark, host of the two-headed demonic leader called the Nameless One, goes after Lyra but Namor rescues her. Then they discover that Loa is missing and Namor swims to the ruins of New Atlantis to find her….

Silver Surfer locates Loa but she tries to stab him in the back—“she” is the villain Tyrak in disguise and the Surfer knew it. Tyrak then grows to giant size and attacks….

Tiger Shark locates Lyra meditating; her strength increases with calm. When fully focused she punches the villain many leagues into the watery distance….

The real Loa meets up with Dr. Strange and they proceed to the palace where they encounter Aradnea; it turns out that she is the mystical conduit for the Undying Ones. Namor arrives to hold off her attendant monsters while Strange battles the sorceress. Loa conks Aradnea on the head, Strange seizes her and utters the spell that drives off the demons. When the dust clears the Undying Ones are gone, the Atlanteans freed. Aradnea tries to kill Strange with a trident but Loa uses her powers to insert her hand into the witch’s chest and disintegrate her. The only challenge left is to face Attuma….
