Final Fantasy IX
Vivi Orunitia is the only party member that can use Doomsday, which is learned from his ultimate staff, Mace of Zeus. When cast, clusters of asteroids and meteoroids gather together in space to create one enormous meteor, which then slowly descends and enters the atmosphere, colliding with the enemy and the surrounding area. It does a large amount of Shadow damage to the enemies and party. Steiner can also use Doomsday as a Sword Magic technique, but the difference between Vivi's spell version and Steiner's Sword Magic version is that Vivi's targets both enemies and party members while Steiner only affects all enemies. In the Japanese version of the game, it was known as Jihad. A powerful combo would be to equip your entire party with items/armor which absorb shadow, allowing you to heal massive amounts of HP with every casting of Doomsday. It is learned for 150 AP, costs 72 MP to use, and has a spell power of 112.

Doomsday can also be used by Hades and the superboss Ozma, though Ozma can use it freely and much more often than Hades.

Trivia
The spell name ジハード, Jihādo, is also used as the Japanese name for the Final Fantasy VI Esper summon Crusader.
