Kaia (Angela Little) was an antagonist in the 2003 episode "The Importance of Being Phoebe" for the TV series "Charmed".
Kaia was a Kieran Demon, a low-level demonic seductress who worked as a stripper in a demonic nightclub. She had the ability to change her shape and had formidable hand-to-hand combat skills. She could also alter her voice to the person she shape shifted into. She also had the constant habit of twirling a lock of her hair.
When Cole was rejected by Phoebe, he started going to the strip club and having Kaia shift into her when she danced for him. Cole used Kaia in his scheme to claim the Nexus and turn Phoebe evil to get her back. As part of his plan, Kaia posed as Phoebe on several different occasions.
On one of these, she helped trick Piper into using the manor as bond to get Paige out of jail. She also managed to make Piper chant the spell to relinquish Phoebe's powers, telling them that she was afraid of hurting someone with her powers.
Kaia began to get a thirst for power, and was determined to be with Cole herself, and wanted to rule the Underworld with him. She made two attempts to kill Phoebe, who was being kept prisoner in Cole's penthouse. However, just when she tried to kill Phoebe with an athame, Phoebe regained her powers and vanquished the seductress with her own blade.
Shortly after the death of Kaia, Cole went back to the demonic stripclub and met a new dancer (Dawn Lewis). When he asked if she knew Kaia, the dancer told him that they were good friends. She then shifted into Phoebe and got on Cole's lap. Cole banished her and continued to watch other Kieran demons dance on their poles.
