Jellica

Jellica is the Sea Overlord and the holder of the Jellyfish spirit, a staff wielding mistress who can neutralize her opponents' physical attacks by having them pass right through her as she can turn into water.

She is revived by Camille so Dai Shi can train under her instead of Carnisoar. However, at first, she forced Camille to be her student and has her attack the Rangers after she personally defeated the Jungle Pride Megazord without trouble. But when Camille couldn't follow her orders, she attacked her with Lily going to her aid followed by Jarrod, who defeats Jellica in a brief fight. By then, she reveals that her mentoring of Camille was a test to see if Dai Shi truly desired her power, becoming Jarrod's new mentor, teaching him to harness his deceit as power. She helped Jarrod and Carnisoar to try killing the Rangers by reviving the White Shadow Guard. She refers to Camille as "Lizard".

When Grizzaka was revived, Jellica sided with him, probably out of fear. During the events at the Rhino Nexus, Jellica battles Dominic and overwhelms him with her abilities until he made a comeback and forced her to retreat. While Grizzaka was fighting Theo, Lily, RJ, and Dominic, Jellica attempted to steal the Crystal Eyes while Jarrod was preoccupied with his fight with Casey. But after Grizzaka's destruction, Jellica reveals her managed to reclaim the three she and Carnisoar gathered for Grizzaka, reviving the Phantom Beast Generals to take over Dai Shi's throne out of spite for him. However, she ends up being destroyed by the three Phantom Beast Generals instead. She was revived by Dai Shi for the final Beast War, but was destroyed again by the Power Rangers and the Pai Zhua Masters.
