Mercury Aqua Rhapsody

Among Sailor Mercury's arsenal, this water technique stands as her single most destructive move. She draws on the Mercury Harp to unleash it, and the attack recurs throughout nearly every incarnation of the franchise: the original manga, the 90s television series, the Crystal films, the live musicals, and multiple video games. Rather than a team maneuver, it is the strongest strike she can loose on her own.

In the anime, Super Sailor Mercury extends an open palm, where her planetary emblem flares to life, and calls out the first word of the phrase. A harp materializes behind her as a jet of water spills from the symbol and coils into the instrument's shape. Strumming its strings while finishing the incantation, she releases a funneling current that races toward her target. She most often deploys it to soften a foe, opening the way for Sailor Moon to finish the job with Moon Gorgeous Meditation.

Sailor Mercury is the sole wielder. She debuts the attack in Act 40 of the manga, using the newly gifted Mercury Harp to shatter the mirror where Fish Eye had trapped her, and later cracks a second mirror in Act 47 that Sailor Jupiter finishes off with her fist. During the Stars arc she turns it against Eternal Sailor Moon while under Galactica's control, only for the Sailor Quartet to shield the target and be knocked aside. The Crystal films echo these manga beats, and on stage she wields a stronger variant, Mercury Aqua Galactica Rhapsody, when Galaxia manipulates her.
