Ovo-pack

The Ovo-pack is a portable energy battery used to charge and power various machines in Final Fantasy: The Spirits Within.

Shaped as cylinderical metal canisters, the energy within is a type of Biotic-energy created through the sciences of Bio Etherium using biological tissue. One Ovo-pack was notably used in conjunction with the Wave Theory to generate an opposite wave pattern to that of the Phantoms' in order to defeat them.
