Abiku Demons (or simply "Abiku") are a type of parasitic demons that move from host to host. These demons prefer to prey on the souls of dead children.
In The Replacement, an Abiku possessed Galvin Burdette while he was venturing in Haiti to retrieve the cure for the Ibi, or darkness, inside of Macy Vaughn. Upon returning from Haiti, the Abiku killed a customs agent, leading the Charmed Ones and Tessa Flores-Cohen to believe that perhaps a vampire was at play. However, when the Abiku killed Mama Roz, a psychic looking over the many artifacts that Galvin brought back along with him, the sisters learned of Galvin's possession and that the Abiku was using him in order to get to Macy.
After revealing himself to Macy, the Abiku chased after her into the woods, where Macy hid inside an abandoned car. The Abiku pierced through the door and nearly got to Macy before her sisters and Tessa intervened. Macy was able to get the Abiku out of Galvin by stopping Galvin's heart. However, in its primordial form, the Abiku was able to escape with Macy back to the attic of Vera Manor. Finding themselves blocked from entering the manor by a force field, Mel and Maggie Vera, Tessa, and Galvin were able to pierce it with Mama Roz's dagger and enter. In the attic, the sisters were able to vanquish the Abiku by stabbing it with the same dagger.
