Asura is one of the bosses in Final Fantasy Legend II (a particularly nasty one, too, if you don't give Mask a good weapon), and Asura is also one of the summoned monsters from Final Fantasy II (Final Fantasy IV j). She is the queen of the summoned monsters, Leviathan's wife, and her effect in battle is that she casts Life 2, Cure 4, Cure 3, or Life, randomly. The main advantage in this is that it gives someone other than Rosa some decent healing magic. However, the randomness of Asura sometimes makes her a little difficult to use effectively.
