Menrva (ミネルヴァ, Mineruva?) is a non-player character in Final Fantasy XIII. It is Galenth Dysley's familiar, having the appearance of a light gray, owl-like bird with the Cocoon fal'Cie brand on its wing and the face of Orphan on its chest. Menrva can turn into an airship and acts as as extension to Dysley's hidden powers, which allows him to turn into his fal'Cie form, Barthandelus.
The Final Fantasy XIII Ultimania Omega reveals Menrva is a type of fal'Cie.
Later, Dysley uses Menrva aboard the Palamecia to turn into his fal'Cie form and provokes the six Pulse l'Cie to fight him. After they defeat Barthandelus, he disappears, Menrva turns into an airship, and takes the l'Cie to the Fifth Ark, where the Cocoon fal'Cie want the l'Cie to improve their abilities to destroy Cocoon.
Menrva later appears in Oerba, when Dysley reveals himself from the guise of Serah Farron and turns into his fal'Cie form and challenges the l'Cie once again. After the fight, he reveals his current plans and events happening on Cocoon and leaves, while Menrva remains and turns into an airship which takes them to Eden.
Her final appearance is when Lightning and the others arrive at the secluded chamber in Orphan's Cradle, where she dives into the pool to complete Orphan's manifestation after Barthandelus is assimilated into the fal'Cie.
Menrva (also spelled Menerva, Menfra, Merva and Mera) was an Etruscan goddess of war, art, wisdom, and health. She contributed a lot of her character to the Roman goddess of wisdom, Minerva, whose symbol was the owl; Minerva is also Menrva's Japanese name. Menrva also seems to be associated with weather phenomena.
