I am sad to report that Susan Aceron Gray, who voiced Sailor Pluto during the Cloverway dub of the Sailor Moon anime, passed away earlier this week after a long battle with cancer. She was 44. She played many other characters through the series including the Kisenian Flower from the Sailor Moon R movie, Byruit (Viluy), Cyprine and Petirol of the Witches 5, Mistress 9 and Elizabeth (Unazuki).
I was lucky enough to meet Susan Aceron over 10 years ago at Anime North in Toronto. She was very kind and quite happy to meet her fans. Her work was cherished by Sailor Moon fans around the world. She will be missed.
