Belias

Belias, full title, "Devil Belias" ("Belias, the Gigas" in the US version), is a summoned creature, called an Esper, from Final Fantasy XII. He is a fire-elemental summon, represents the zodiac of Aries and is the first Esper fought and acquired by Vaan and party. He requires 10 LP to acquire as a summon and his two attacks are called Pain Flare and Hellfire, the latter of which is named after the Overdrive of fellow fire-elemental summon, Ifrit. His physical appearence looks similar to a merged version of the GF, Brothers.

In game description
Scion of darkness and guardian of the Holy Realm, made by the gods in opposition to the Transcendent Loghrif, scion of light. Called the Gigas for his appearance: man and monster fused as one. Considered a mistake upon his making, and receiving not his intended role, the Gigas challenged the gods and lost. Scorned by his masters, he found another: the Dynast-King, whose tomb he swore to protect for eternity.
