Shiva

Shiva is a frequently recurring Ice-elemental summon. A blue-skinned woman with clothing of the same color, her signature attack is Diamond Dust.

Along with Ifrit and Bahamut, she is one of the few summons to appear in every main series game from Final Fantasy III through Final Fantasy XV (although in Final Fantasy XII she appears as an airship instead of a summon). She also appears in every main series side-story and sequel that features summons, with the only exception being Crisis Core -Final Fantasy VII-.
