- —Attack Phrase
Jupiter Thunder is variant of Supreme Thunder and Sailor Jupiter's primary attack. An offensive attack, Jupiter Thunder is one of Sailor Jupiter's strongest attacks and can be used in tandem with other Sailor Scout attacks, defensive or offensive.
Jupiter Thunder requires that Sailor Jupiter cross her arms over her chest with her index and pinky finger extended on each hand. Harnessing the element of lightning, a lightning rod extends from her tiara and absorbs the electrical energy from lightning bolts as they crash down from the sky. Sailor Jupiter throws her arms open and sends forth a giant spherical arc of electricity at her enemies.

Jupiter Thunder was an attack rarely been used to destroy monsters; Sailor Jupiter typically used the attack to damage them in order for Sailor Moon to destroy them with her ability of the moment. However, there have been at least three monsters destroyed by this attack. The first two were red and blue Doom and Gloom Girls prior to Sailor Moon's confrontation with Queen Beryl.

After regaining her memories and abilities as Sailor Jupiter, the third instance a monster was killed by Jupiter Thunder was when the Sailor Scouts faced the Cardian Nacrid. She combined Jupiter Thunder with Sailor Venus's Venus Crescent Beam.
- The defunct official website for Sailor Moon incorrectly named the attack "Jupiter Thunder Crush". This was likely a typo.
