The Blue Troll is an enemy in the Dawn of Souls and succeeding versions of the original Final Fantasy. In the Hellfire Chasm, it is found only on the Overworld level while the party is sailing in the ocean. Despite its coloring and the terrain where it appears, it is not of the Water element and is in fact weak to Fire, therefore a Fira spell spread across the entire enemy group will kill all Blue Trolls present.
Blue Trolls have a similar blue and gray coloring as Sea Trolls, the difference is that their hair and skin color are switched.
troll is a supernatural being in Norse mythology and Scandinavian folklore. In Old Norse sources, beings described as trolls dwelt in isolated rocks, mountains, or caves, lived together in small family units, and were rarely helpful to humans. Later, in Scandinavian folklore, trolls became beings in their own right where they lived far from human habitation, were not Christianized, and were considered dangerous. Depending on the region their appearance varied from ugly and slow-witted to looking and behaving exactly like human beings. Trolls are sometimes associated with particular landmarks, which at times are explained as formed from a troll exposed to sunlight.A
