First appearance: Act 6
Sailor Jupiter does some ballet dancing for a bit (what is it with this series and random ballet dancing?), and then fires a bolt of lighting at her enemy.
Anime/Manga Comparison:
Sailor Jupiter's first attack in the manga was "Flower Hurricane" (many of Jupiter's attacks are related to plants in the manga), and immediately after that she used an attack that did not have a specific name. She subsequently attacked twice using an attack that was visually similar to her second attack, but was given the name "Supreme Thunder". "Supreme Thunder" was Sailor Jupiter's first attack in the anime, and visually it was similar to in the manga. "Supreme Thunder" looks quite different in PGSM. In the current rerelease of the manga, Sailor Jupiter's second attack and her two uses of "Supreme Thunder" were all given the new name "Jupiter Thunderbolt".
I had previously written that Sailor Jupiter did not use an attack called "Supreme Thunder" in the manga. Thanks to DoseiNoSenshi for pointing out this mistake.
