Neptune's Daughter

Aquafiend, the only demon capable of surviving exposure to free-running water, swipes the trident of King Neptune, ruler of the seas. His daughter, Marina the Mermaid, is granted human legs for a temporary period, and seeks out her love interest, Chad, to gain the Rangers' help in recovering the trident from the demons, who seek to destroy the Aquabase with it. After the trident is returned to King Neptune, Marina is allowed to alternate her time between the surface world and the seas, allowing her to continue her relationship with Chad.

Il Re Nettuno, padre della sirena Marina, viene rapito da un demone per usarlo al fine di prosciugare l’acqua di Mariner Bay; così la sirena chiede aiuto a Chad ma in quel momento i due vengono attaccati da Vypra. I due vengono poi aiutati dagli altri Rangers e alla fine Chad riesce a salvare la situazione.

Marina advarer Chad om, at Diabolico har stjålet hendes fars magiske trefork for at dræne havet for vand og gøre Aquabase sårbart over for angreb.
