Pandora's Box
From Final Fantasy Wiki
Pandora's Box is an Enemy Skill in Final Fantasy VII. It deals heavy magical damage to all enemies, and ignores defense. However, at 120 MP, it is the most expensive Enemy Skill to cast in the entire game. The spell can only be learned from the enemy Dragon Zombie at the Northern Crater, but only once due a glitch in the game's programming. Therefore, if the player does not learn it after the first casting, Pandora's Box is impossible to obtain.
