-He's a ram (Ifrit is some kind of goat/lion thing
-He uses Eruption
-He uses Crimson Cyclone
-He uses Inferno
-He uses nails

Belias, the Gigas: Step into the inferno! Step into my hellfire!
Belias, the Gigas: Are you not yet ash and bone!?
Belias, the Gigas: That your wrath...might eclipse mine...

The Amalj'aa have a Brotherhood of Ash, and when you fight Ifrit, there's a Solar Eclipse.

Can't be TOO much of a stretch...
