Melaina

Melaina was an android which resembled a blonde teenage girl. She was constructed by Inspector Drake and sent to Magdalene Academy to introduce cerulium bracelets to the students. By the time Jorjie Turner arrived at the school, Melaina had given bracelets to the two other girls in her study group, and eventually got both Vibeka and Jorjie to wear them as well. When K9 destroyed the bracelets, Drake deactivated Melaina, revealing her true nature to the other students. (TV: Sirens of Ceres)
