Shiva (Final Fantasy VI)

Shiva is an esper in Final Fantasy VI who can be acquired as a magicite after being fought.

Profile
Shiva appears as a blue, humanoid creature with a very feminine look. She wears small, pink clothing, and has green hair.

Story
Shiva encounters Returners in the Magitek Research Facility of Vector. After being drained of her power, Kefka disposes of her and Ifrit in a waste chute. Believing they mean the two espers harm, Ifrit attacks the party. Shiva soon senses Ramuh's power within them, and halts the battle and the two grant their abilities to the Returners.
