Charlie is a gargoyle created by Marcus Today, who can communicate with Matilda no matter his whereabouts and expresses himself using the Warbler Island sign language. He is made of gray stone and looks just like Matilda, except without a bow. It is mentioned several times that he has four thumbs. Since he uses Warbler Island sign language, Sky and Crow can understand him, and Gunnar Haluki is learning too. Charlie was brought along with Alex Stowe and Sky during their mission to rescue Aaron, where he drove Claire Morning's boat when Alex, Sky, Aaron, and Kaylee Jones were fighting with the gorillas.
