Sailor Moon's Moon Spiral Heart Attack
Michiko Abe (original anime)
She was created from a gramophone playing Doctor Tomoe's Hope for the Future "waltz". She first appeared dressed in a ball gown and attacked with exploding blue roses, but changed into a different form after being hit with World Shaking by Sailor Uranus with attacks that include shooting energy waves and playing albums to create giant musical notes to attack her enemies.
Eudial took Chikuon with her as she extracted the Pure Heart from the host of a fancy party, which the Sailor Senshi were attending. Chikuon attacked them, but her album player was destroyed by Tuxedo Mask. Sailor Moon destroyed Chikuon with Moon Spiral Heart Attack.
