| Mercury Aqua Storm
Mercury Aqua Storm was an attack used in the live-action series. It appeared once, in Act 42, where it was used against a very powerful Youma.
To perform the attack, Sailor Mercury crossed her arms in front of her chest, her right hand holding her Sailor Star Tambourine and her left hand with her thumb, index, and middle fingers extended. She lifted her left hand in the air and lowered her right hand, then lifted the Tambourine in the air with her left hand in front of her face, palm out, again with the thumb and two fingers extended. While in this pose she spun around once, then lifted her left hand into the air as she thrust the Tambourine out toward her target, releasing the energy of the attack.
