Kiteretsu Daihyakka (キテレツ大百科) (Also known as Kiteretsu Encyclopedia or only Kiteretsu) is a manga series by duo Fujiko Fujio which ran in the children's magazine Kodomo no Hikari from April 1974 to July 1977. The manga was later made into a 331-episode anime television series which ran on Fuji TV from March 27, 1988 to June 9, 1996. A Hindi dub of the anime airs in India on Disney Channel India, Disney XD and Cartoon Network. The series was licensed for Spain by LUK Internacional under the title of "Kiteretsu, el primo más listo de Nobita". (English Translation: Nobita's Smarter Cousin.) As of now, a remastered version of the series airs on Animax in Japan.
An English dub of the anime aired in India on Cartoon Network and Pogo around somewhere in 2015, however it no longer airs on both channels and is now extremely hard to find. The only footage of the dub is a low quality recording of it.
