“Conqueror of the skies, Bahamut has known many names; the Dragon King, the Hallowed Father, the First Sire.”
—Dissidia Final Fantasy Summon Compendium
His attack, Megaflare, sometimes translated as Sun Flare, deals non-elemental magic damage which ignores defense and evasion. There are, however, other variations to Megaflare corresponding to different appearances of Bahamut, including Tera Flare, Giga Flare and Exa Flare to name but a few.
Bahamut is typically considered the strongest among storyline summons and more often than not, the player must prove his/her worth by winning a battle against Bahamut himself, or, rarely, another storyline boss.
