"Galactica Super String" is a powerful cosmic force wave attack used by Sailor Galaxia in both the manga, musicals and Sailor Moon Cosmos.
Etymology[]
Superstring theory is a longstanding attempt to unify all of the forces of Physics into a single theory to describe everything large and small.
Manga[]
Galactica Super String seemed to create a wave of Cosmic energy around Sailor Galaxia which she would then direct and fire at enemies.
Sailor Galaxia uses this attack in an attempt to knock Eternal Sailor Moon off the cliff into the Galaxy Cauldron while Chaos is awakening, but Sailor Chibi Chibi blocks the attack with her scepter to Galaxia's surprise.
Musicals[]
The attack was first used in The Eternal Legend and its revised edition by Sailor Galaxia to attack Chaos after being freed from his control. In Le Mouvement Final, she uses it as she attacks the Outer Senshi.
