Sahagin Chief is an enemy from Final Fantasy X-2. It is a larger version of the Sahagin, thanks to the Cactuar's needles.
Sahagin Chief is weak to Lightning. An Alchemist with Item Lore using Lightning-elemental items helps, as do Black Mages and a Mascot with Black Magic. Sahagin Chiefs are of no particular threat.
Sahuagin are fishlike, monstrous humanoids that appear in the Dungeons & Dragons role-playing game.
