Description
Namor is forced to flee Atlantis, but in his escape he's caught in a nerve gas explosion. Triton finds him unconscious and takes him to the Fantastic Four. The explosion has damaged Namor's ability to breathe air. Namor freaks out as usual and attacks the Fantastic Four, but he's defeated as he begins to suffocate. Reed constructs a costume for him that allows him to breathe air. Meanwhile, Orca and Virago claim the throne, but it's short lived as nerve gas sweeps through Atlantis.
