, also known as '''the Ultimate Power''', is a
Fictional Character on
The WB television series ''
Charmed ''. She is played by actress
Kaley Cuoco .
Billie Jenkins was introduced, in the show's eighth season, as a young witch who pays more attention to demon fighting than to her education. Billie was put under the tutelage of the Charmed Ones after she asked them to teach her everything they know about witchcraft. This, at the time when the Charmed Ones were thought to be dead, proved useful for the three sisters, as Billie could carry out smaller magic-related tasks and also to cover for them.
Billie's backstory involves the abduction of her sister,
Christy Jenkins , by mysterious demons with unknown intentions. This -- along with the fact that the incident was never mentioned by her parents, leaving Billie even more confused -- was the main motivation for Billie to train and become skilled in using her powers. Her main objective was to find out who kidnapped Christy and why, and to save her if she is still alive. Upon meeting with an Angel of Destiny, Billie was assured that her sister is alive and she will eventually find her. Her sister was revealed to be kidnapped by a surprisingly alive Triad because she is the key to "ultimate power".
Billie has finally found her sister, after fifteen years. She was teaching Christy how to control her powers. When Christy got kidnapped by the demons that were sent by the Triad, Billie went after her. While they were both down in the underworld, Billie convinced Christy to vanquish the demons. Together, with Christy's
Pyrokinetic powers and Billie's
Telekinesis , they killed the demons. What Billie doesn't realize is that Christy is working with the Triad, the same trio of demons who sent
Cole Turner /
Belthazor after the Charmed Ones. It is originally believed that they are the major threat the sisters are supposed to face. This is not the case, as Leo should have returned after two of them were vanquished. The remaining Triad member reminds Christy that Billie is the 'ultimate power,' whatever that means, and she must save her (in other words, turn her against the Charmed Ones). Unfortunately, Christy has succeeded in doing so.
It is very likely that the Charmed Ones will have to face both of them at some point in the future.
Billie has the power of telekinesis, and she can use it to amplify her acrobatic abilities. She is cocky in her own powers and skills, but is still bested in a fight by Paige. Recently she received the power of projection. This power, yet to be defined in detail, projects Billie's thoughts into reality, and is triggered by strong emotions.
Billie inherited her powers from her grandmother on her mother's side. Her mother and father, however, are perfectly normal human beings, thus witchcraft skipped a generation in her family.
Billie and
Christy are the most powerful witches in the world, second only to the
Charmed Ones .
