- Normal: "A fiend whose incredible speed makes it an elusive and annoying foe. Beware its Mind Peck attack, which causes MP damage."
Oversoul: "Sometimes uses Berserk and Confusion attacks. Its speed makes it a vexing opponent that can easily dodge attacks if your accuracy isn't high enough."
The Aquila is an enemy in Final Fantasy X-2. As an aerial fiend, it has high Evasion, however, relatively low Magic Defense. Magic is an effective weapon against this enemy.
In the Fiend Tale endings, one notable Aquila knew of Belgemine from two centuries ago. Belgemine sent this fiend on an ark with humans and other fiends to escape Sin and make a new life for themselves. Eventually, Aquila was sent to see if Sin was gone, returning to report of the Eternal Calm.
