Grey Griffin

Griffin voices Monster Girl, a founding member of the Teen Team who ages backward whenever she transforms, along with Shrinking Rae and several smaller characters, in Invincible, the Skybound Entertainment series adapted from Robert Kirkman's comic for Amazon Prime Video. The part sits comfortably within a career built on playing young heroines and complicated female characters across long running animated series. Her casting brought an experienced hand to some of the show's more physically strange and emotionally difficult roles.

Griffin has spent more than two decades as one of American animation's most in demand performers, voicing Daphne Blake across the Scooby-Doo franchise, Azula in Avatar: The Last Airbender, and Vicky in The Fairly OddParents. Her range extends across ages and tones, from Sam Manson in Danny Phantom and Frankie Foster in Foster's Home for Imaginary Friends to the title character's foil Mandy in The Grim Adventures of Billy and Mandy. She has also voiced multiple roles on The Loud House and The Simpsons, adding to a resume built on stepping into a huge range of animated voices.
