Lucy is the pet orangutan of Crystal Kane. She is mostly the comic relief of the series. However, her antics sometimes can cause troubles like beaming an Assault Weapon System by mistake or knocking Jake Rockwell with an experimental Sonic Beam. She is also seen helping Crystal to fix problems in the space station Sky Vault.
Although she's not meant for combat, Lucy was helpful to the Centurions in a few occasions like providing them new Communicator Watches when they're stranded on an island or giving them clues about Doc Terror's plans.
