Hydro Girl was a teenage girl from the planet Aquatos. She was kidnapped by Gleeman Vox and forced to fight for DreadZone while she was helping to construct a shelter for baby lunar seals injured in an interplanetary tanker accident. The Starship Phoenix headed to Aquatos to investigate her disappearance. She eventually became one of the higher-ranking contestants in the Dreadpoint table.
