Ifrit

Ifrit (イフリート, Ifurīto ?), also called Jinn and Iflyte, is a Fire-elemental Summon which appears in several games in the series. His signature attack is called Hellfire, or sometimes Inferno or Flames of Hell, and deals scorching Fire-elemental damage to all opponents. He is one of the most frequently appearing summons and is often a rival to the ice summon Shiva.

Like most re-appearing summons, Ifrit changes his appearance in each game, but remains somewhat similar in each game although he curiously appears more and more "beast-like" and less "humanoid" as the series evolves. In general, Ifrit has brown skin with long horns and claws, covered by a simple kilt-like covering around his waist.

Final Fantasy IV
Ifrit, called Jinn in the SNES release, is automatically obtained when Rydia rejoins the party. It has a casting time of 4, cost 30 MP, and deals Fire-elemental damage to all opponents.

Final Fantasy IV -Interlude-
Ifrit returns as a Summon spell for the imposter Rydia and Rydia in the sequel of Final Fantasy IV. Its signature attack, Hellfire, deals moderate Fire-elemental damage to all enemies at the cost of 30 MP.

Ifrit is wielded by the Flamehound, one of four Eidolon-holding bosses found within the Lower Section of the Tower of Babil B11. Once it's defeated, it leaves behind an orb of red light. The imposter Rydia claims the light and regains the ability to summon Ifrit during battle. Ifrit along with the other reclaimed Eidolons are later summoned by the imposter Rydia on B6 of the tower to battle against the party.

Final Fantasy IV: The After Years
Ifrit is summoned by the Mysterious Girl during Edge's tale, and serves as an unbeatable boss. After the battle, he chases Edge through the Tower of Babil much like X-ATM092 in Final Fantasy VIII.

In The Crystals Tale, the player can obtain Ifrit by going to Eblan and defeating him. He can be summoned by Rydia after obtaining him as a summon command. Like the original game, he deals moderate fire-elemental damage and costs 30MP.
