Minerva (Final Fantasy VII)

Minerva is a character from Crisis Core -Final Fantasy VII-. Although her exact nature is not known in details, she is related to the planet's consciousness (Gaia), and may either be its personification or its goddess. She is physically very similar to Safer Sephiroth (Sephiroth's final boss form in Final Fantasy VII), albeit with a female body and blonde hair.

Crisis Core
In the main storyline, Minerva appears when Genesis is defeated by Zack. She lures Genesis in the Lifestream and seemingly seals him there until he escapes in Dirge of Cerberus.

Minerva also appears as a secret boss in the Northern Crater.
