The name of the cartoon is "Don Dracula" (or "Don Dorakyura" in its original Japanese).
The character began in a three part manga (Japanese comic book) published in Japan in 1979. It was written by Osamu Tezuka and published by Akita Shoten Publishing.
In 1982, the manga was turned into a TV cartoon series by Tezuka Productions but only eight episodes were created before the sponsor went bankrupt. The character of Don Dracula occasionally appears in other outlets like the 2004 GameBoy Advance game "Astro Boy: Omega Factor."
