The Fluorescent Water-Man from Mercury is an aquatic alien in Xen's collection.
The Fluorescent Water-Man from the Mercury was captured by Xen the Aquarium Owner to be added to his Aquarium when Xen chose to explore Earth's Solar System. When Xen captured Aquaman, Mera and Aqualad, he presented his other four captives to the trio, including Fluorescent Water-Man. The trio were able to break free along with Fluorescent Water-Man and Xen's other captives. Aquaman then acquired Xen's duplication ray with the help of Mera and duplicated Xen, making an obedient Xen army. Aquaman ordered the army to return Fluorescent Water-Man to his home on Mercury.
