Charm Buster was an attack used by Mimete of the Death Busters in the Sailor Moon manga, anime, crystal and musicals. In the Cloverway English dub it was called "Stage Fright", though it did retain its name once in the original dub.
In the manga, the attack was first used in Act 26 against Sailor Venus's Venus Wink Chain Sword.
In the anime, the attack was first used in Episode 114. Using her wand, Mimete unleashes a blast of purple starshape projectiles. It caused harmful effects on the victims, knocking ordinary civilians to go unconscious. In episode 120, she also used it to incapacitate Sailor Venus and Sailor Mercury.
In the musicals, the attack was first used in Mugen Gakuen - Mistress Labyrinth to knock down Usagi and Minako.
When confronted in a fight, Mimete uses her staff to throw powerful energy projectiles.
