Major Story Arcs
The Fluorescent Water-Man from Mercury was taken from his home by Xen the Aquarium Owner to be added to Xen's Aquarium. Sometime later, Xen came to Earth and planned to capture Aquaman, Mera and Aqualad and succeeded, but they were able to escape along with Fluorescent Water-Man and Xen's other three captives. Aquaman and Mera then managed to take Xen's duplication ray and made duplicates of Xen who Aquaman instructed to return Fluorescent Water-Man to his home on Mercury.
