While the game doesn't explicitly state what animal Ifrit is based on, its appearance and abilities strongly suggest it's inspired by mythological fire demons, specifically the Ifrit from Arabic mythology.
Here's why:
* Appearance: Ifrit in FFX has a fiery, demonic appearance, with a horned head, glowing red eyes, and a humanoid body covered in flames. This closely resembles depictions of the Ifrit from Arabic folklore.
* Abilities: Ifrit's attacks in FFX are mainly fire-based, such as Hellfire and Blaze, which further reinforces its association with fire and demonic imagery.
It's important to note that Ifrit in FFX is a unique creation that draws inspiration from various sources, but the most prominent inspiration comes from the fiery demon of Arabic mythology.
