Dahaka (Final Fantasy XIII)

Dahaka (ダハーカ, Dahāka) is a Gran Pulse fal'Cie from Final Fantasy XIII, a masked flying serpent that resides in Taejin's Tower. Territorial, Dahaka attacks anything that invades his abode. However, after having his tail chopped off by the Menhirrim, Dahaka confronts Lightning's group at the top of the tower and unfolds its true form, a demon resting on a throne, before being destroyed.

Datalog
Residing within Taejin's Tower, this Gran Pulse fal'Cie soars through the sky with an ease that seems almost uncanny given the bulk of its form.

''Although the majority of fal'Cie on Gran Pulse dedicate themselves to terraforming or other tasks of environmental modification, Dahaka does nothing of the sort. Plausible conjectures as the nature of the flying fal'Cie’s duty include some manner of aerial monitoring or the search for something the heavens conceal.''

Battle
Dahaka is fought at the top of Taejin's Tower.

Trivia

 * Dahaka shares its Japanese name with Taharka, a boss from Final Fantasy IX.

Etymology
Dahaka and his central role in the story derive from Persian and Arabic myth, where he is represented as a serpentine God-King that resided in an impregnable fortress, instigating terror over his populace and eating men, and is ultimately opposed and overthrown by his followers, led by the hero Fereyedun.
