Barbas (portrayed by Billy Drago) is a character from the TV series Charmed, first appearing in the Season One episode "From Fear to Eternity".
Barbas, also known as the Demon of Fear, is an ancient and powerful upper-level demon. His primary power is the ability to read the fears of his victims and use those fears against them.
While trapped in Purgatory, Barbas met another demon named Stimple, who taught him how to astral project. Barbas then began manipulating Cole Turner and the Charmed Ones as part of his plan to escape. After creating enough conflict, Barbas tricked Paige into giving Cole a power stripping potion. When Cole drank it, Barbas materialized and absorbed the powers.
When he confronted the sisters, Paige managed to orb another power stripping potion at him. The stolen powers were then returned to Cole, who vanquished Barbas with an Energy Ball.
After Gideon's betrayal, Leo became obsessed and started hunting down Barbas who helped Gideon in trying to kill Wyatt. However, Barbas manipulated him into attacking an Elder named Zola by comparing him to Gideon. As Barbas got healing from a demonic healer, he was visited by a floating head that told him to go after Chris.
Barbas returned to his lair and wanted to go after the sisters next, though Paige and Phoebe confronted him instead. Barbas read their fear thinking it would paralyze them, though the sisters replied that their desire to protect their nephews was stronger and vanquished him with a potion.
