This fun doll franchise launched in 2010 by Mattel and is making a freakishly good return over two decades later, as Monster High's group of "somewhat different" teenagers face the world together. Frankie Stein is a simulacrum, specifically the daughter of Frankenstein's monster and his bride. She is sweet, polite and a little bit clumsy but as the youngest of the group, she tries to learn about the world through monster teen magazines!
