Jupiter Comes Thundering In

Act 1
Queen Beryl awakens the Negaforce who advises her about the Rainbow Crystals, the Star Crystal and the 7 Shadows. Meanwhile, on her way to school, Serena is saved from 3 thugs by a girl named Lita whom Luna senses something about. Back in the Negaverse, Beryl tells Zoycite and Malachite about the Rainbow Crystals and gives Zoycite Nephlite's Star Crystal as a homing crystal. Zoycite then locates a man named Game Machine Joe who has the first Rainbow Crystal inside him. At Serena's school, she befriends Lita to Melvin's dismay. After school, Serena shows Lita the arcade when Luna, Amy and Raye come in and meet Lita. Then, Joe gets toys from the crane machine to give to poor kids. Just then, Zoycite ambushes him and tries to extract his Rainbow Crystal.

Act 2
Suddenly, Lita fights Zoycite to defend Joe. When Serena and Luna arrive, Joe shows no gratitude. Luna however decides the 2 are worth watching. Later on, Joe and Lita talk when Zoycite comes back and extracts the Rainbow Crystal, turning Joe into a monster called Game Machine Man. Sailor Moon has trouble with him while Luna notices the sign of Jupiter on Lita's forehead.

Act 3
As Sailor Moon gets caught, Luna gives Lita the Jupiter Power Stick which she uses to transform into Sailor Jupiter. When Sailor Moon is freed with Jupiter Thunder Crash, Luna gives her the Crescent Moon Wand which she uses Moon Healing Activation with to turn Joe back to himself. Back at the arcade, Serena introduces Andrew to Lita.
