Description: Once again, the Ice Goddess Shiva returns to Final Fantasy as a summon. Shiva's real highlight is her extremely high agility; with even a moderate amount of luck, you should be able to get in some extra turns during the course of a battle. She'll lose HP quickly, though, so be use to remember to use those ice attacks on her to keep her safe.

Special Move: Heavenly Strike

Shiva will draw out an incredibly large block of ice and drop it down on a single enemy. The attack will deliver non-elemental damage and delay the enemy's next turn.

Overdrive: Diamond Dust

Bahamut charges four balls of dark magic and tosses them, attacking all enemies. Tends to be quite useful when facing multiple enemies.

Special Move: None

Overdrive: None

How to Break Damage Limit: Obtain and activate Auron's legendary weapon, the Masamune.

Yojimbo's Location: To get Yojimbo, travel to the Cavern of the Stolen Fayth near the northeast part of the Calm Lands. Defeat him in battle, then proceed to speak to him: you'll be able to negotiate a fee for his services. Choose "To defeat the most powerful of enemies" to start with the lowest asking price.

Yojimbo's Initial Abilities: None.

Description: Anima is initially seen with Seymour, but later on in the game the party can acquire it.

Special Move: Camisade, Razzia, Passado
