"Samael Jihad" is an attack used by some of the villains in the Dracul arc of the Sailor Moon musicals.
Nomenclature and Etymology
The attack was named after Samael, a figure in Judaism who has been thought of as both good and evil and the term jihad which means "struggle" in Arabic.
Information
The attack was first used by Undead Berserk in "Pretty Soldier Sailor Moon ~ New/Transformation - The Road to Become the Super Sailor Guardian - Overture of Last Dracul" as an attempt to seal Sailor Moon away in the underworld. However, Count Dracul protected Sailor Moon from the attack by shielding her and was sealed away in the underworld instead.
The second time it was used was in "Pretty Soldier Sailor Moon ~ Decisive Battle / The Forest of Transylvania – A New Arrival! The Guardians Who Protect Chibi Moon", where Baron Gilles de Rais successfully used it to strike down the Sailor Senshi. However, Sailor Astarte used Solomon Versus to reverse the effects of the attack.
