Judith, Aspen and Colin went on a deep-sea adventure along with two associates, Shethal and a sheik (no name mentioned in Fathom Vol. 4) that brought them here on a mysterious discovery. While Aspen confronts Padma (sister of Shethal who's now a sub-oceanic creature) Judith and Colin are captured by a surface dweller Takeo Nakamura and his own Tigersharks. Nakamura tries to harness the power of the Blue of his own using some experiments on Judith, but things got awry when an experimental entity of the Blue possesses Judith giving her unique Blue-like ability and killed Nakamura and his Tigersharks.
