In Arabic mythology the Efreets (meaning: strong one) are considered a type of jinn that were typically portrayed as spirits of fire. The Efreet is the second most powerful form of jinn after the marid. It is written in the Qur'an that when King Solomon asked all the creatures who could bring back the throne of the Queen of Sheba the fastest, an Efreet represented the jinn and boldly stated that he was best suited to the task. However he was outperformed by means of a prayer.
In more popular culture Efreets (better known as Ifrits) are powerful spirits that embody fire. They generally consider themselves superior to all other races because of their age and deeply resent that humans have found a way to mystically control them. When summoned, they will do the bidding of their master but will often try to twist their wishes to do harm to others.
Ifrit appears as one of the three minibosses during the Lord of the Flies quest. Players can obtain the ability to fuse him through a quest given by the Cathedral Master in Shinjuku Babel. His fusion is a special double-fusion of Pyro Jack and Jinn.
