Marina was a mermaid princess and daughter of King Neptune who had been left for dead by an unknown Evil, until Vypra rescued her and tricked her into capturing Chad, the Blue Lightspeed Ranger. As time went on, she grew to love Chad, even though she knew that their relationship could never be possible (similar to Hans Christian Andersen's story of The Little Mermaid).
When one of Bansheera's monsters stole her father's trident, Marina decided she needed to ask Chad and the other Rangers for help in getting it back, because the trident controlled the waters and tides of the planet, and if it was not retrieved, Neptune would lose his powers and cease to exist. Marina was transformed into a human so she could go on land, but there was a huge risk: she would grow weaker and eventually cease to exist herself the longer she was away from the ocean.
- The story in which Marina is deceived into doing an evil deed, saved from dying, and then returned to the ocean is similar to that of Lelai from the Hikari Sentai Maskman Movie.
- It is possible that in Time For Lightspeed that Chad was looking for Marina with his binoculars during the scene where he was at the beach as a lifeguard.
