He is perhaps best known in animation for his role as "King Koopa" in DIC's Super Mario series*, but I'm posting this here since he also did live action movies and TV. Wikipedia says he died of cancer. Yeah, yeah, I know, but that's all I've got. I actually learned this from a YouTube video, so I can't post a link. This leaves John Stocker (Toad) and Jeannie Elias (Princess "Toadstool", as she was called in North America at the time) as the last surviving original cast members of The Super Mario Bros. Super Show. Well, them, and Walker Boone (second voice of Mario; I think he's still alive, anyway), and Tracey Moore (second voice of Princess "Toadstool"), who both appeared in the later two shows (The Adventures of Super Mario Bros. 3, and Super Mario World [where John Stocker voiced Oogtar]) . *Along with John Stocker, he was the only voice actor from The Super Mario Super Show who also appeared in the other two shows as well.
