Madeleine Joan "Maddie" Blaustein (formerly credited as Addie Blaustein; October 9, 1960 – December 13, 2008) was an American voice actress. She was known for her voice-actor work for 4Kids Entertainment and DuArt Film and Video.
Early life:
Blaustein was born the second-oldest of 5 children in Long Island, New York. She was born intersex and was assigned male at birth. She lived as male for many years before transitioning to female. Her experience as an activist in the transgender community helped her to organize and support groups of people in Second Life.:

Career:
Until her death, Blaustein was the voice of Sartorius in Yu-Gi-Oh! GX. She was also best known as the voices of Meowth in Pokémon (Episodes 29-Season 8) and Solomon Muto (Sugoroku Mutou) from Yu-Gi-Oh! second series anime. She was also Chef Kawasaki from Kirby: Right Back At Ya!, Doctor Kureha in One Piece, and Arngrim, Lawfer, and Lezard in Valkyrie Profile. She was also a comic book writer and artist, having worked for both Marvel Comics and Milestone Comics, and an animation director. Later she served as Creative Director for the Weekly World News. Video-game localization coordinator and translator Jeremy Blaustein is her brother.

She provided Margarete's voice in the English version of the PlayStation 2 game Shadow Hearts. Most notable is her great variety of voices. In Valkyrie Profile, for example, she was able to perform a very "tough", deep masculine voice (Arngrim), as well as a high-class one (Lawfer) and a suitable and somewhat androgynous voice of a mad scientist/sorcerer (Lezard Valeth). In Shadow Hearts, Margarete is voiced in a deep, feminine, and seductive style. During the 2004 Democratic Party primaries, she appeared as Sméagol on the Mike Malloy Show, announcing a satirical presidential bid. She was also the third English-speaking voice actor for E-123 Omega of the Sonic the Hedgehog series.

Under the pseudonym “Kendra Bancroft”, Blaustein was one of the content creators in the Second Life platform, where she was a very eager participant since 2004, and earned a reputation as an innovative, competent, and very reliable 3-D modeller in the many communities where she participated.

Blaustein died on December 11, 2008 from an untreated stomach virus.
