Ifrit is a summon in multiple Final Fantasy video games, originating in the Japan exclusive Final Fantasy III for the Famicom. Initially the creature looked like a hybrid of a beast and of a human, though more recently he resembles a demonic being, appropriate for his fire based attacks.
In his initial appearance, Ifrit could be used after purchasing Heatra. His three attacks include Healing Light, which heals all of the party members, Hellfire, which will deal fire based damage to a single opponent, and Inferno, which damages all opponents on the screen.
In Final Fantasy IV, Ifrit will automatically become a summon when Rydia joins your party as an adult. It should be noted that in the SNES version of the game, or in other words the American version, Ifrit was known as Jinn, though this was altered when it was remade for the Game Boy Advance and Nintendo DS (as well as the PlayStation).
In Final Fantasy V, Ifrit must be fought in order to be obtained as a summon. You'll fight him in the Ancient Library, which according to a non-playable character was meant to be burned by the beast.
In Final Fantasy VI, the last of the SNES Final Fantasy titles, Ifrit was an Esper who offered himself to the party after being defeated in a garbage chute along with Shiva after he learned that the party has the power of Ramuh. According to him, the two were brothers - probably not in literally.
Ifrit appeared in Final Fantasy Tactics Advance, though the player didn't have to battle him in order to add him to the summon roster. In Final Fantasy XII: Revenant Wings for the Nintendo DS, the player is required to fight Ifrit at the beginning of the adventure. After the fight, you won't obtain him, though will after another battle against him in the game. In Final Fantasy Tactics A2: Grimoire of the Rift, Ifrit can become a summon by wielding the Staff of Protection.
The battle to see who is better - Ifrit or Shiva, raged on in Final Fantasy Fables: Chocobo Tales for the Nintendo DS. In the second tale, Ifrit apparently had compassion for Shiva and attempted to convince her that her ice was more powerful than his fire - and technically he was correct, as in the series ice outdoes fire. In the game, the Chocobo can summon Ifrit by using one of his six different cards.
