Libido is characterized as both a sexual desire and instinctual energy shown as a driving force in the series used by Star Drivers.


Libido is used by Drivers as a way to fuel Cybodies. It's also used to determine the power of a Star Sword and is the energy used to regenerate a broken Cybody. Libido varies from person to person such as Reiji who possesses an immense libido capable of increasing a Star Sword to colossal proportions.
