Hydrania

Hydrania is Hydron's long-lost daughter, who was rumored to have died in a conflict called the Zone Wars. Not much more is known about her, except that Flogg impersonated her once, so she likely looks just like the impersonation. Since Hydrania's clothes don't show any kind of aquatic equipment (like Hydron and Aquata), it can be assumed that Hydron met Hydrania's mother after he left Serus. Cute
