Onion Mastori (TV series)

Onion Mastori (オニオン・マストーリ) is an American-Japanese-Singaporean animated television series originally created by Jay Mastori. The series was produced by Telescreen BV, Egmont Imagination, Bee Train, King Rollo Films and Landmark Entertainment Group in association with Mastori Media (Jay Mastori's own production company). The series is based on the series of graphic novels of the same name. The series is mostly inspired with an aesthetic by anime, pulp magazines and the anime series Detective Conan and Dragon Ball Z.

The series initially debuted on Nickelodeon on October 20, 2002 for one season. The show was a success after the first season, which led to more seasons of the show to air, and some episodes have attracted over three million viewers; despite being aimed primarily at children, it has developed a following among teenagers and adults for its themes. The series has received worldwide critical acclaim since its premiere and had gained enormous popularity by its second season, and since 2010, becoming one of Nickelodeon's most popular series of all time, garnering high ratings, and anchored Nickelodeon as the network's top-rated show. A feature film, Onion Mastori: The Great Quest, was released in theaters on July 1, 2005.

In 2009, the show was planned to continue beyond the eightieth season. However, in 2010, the series' creator Jay Mastori decided to move onto a different series: Nickelodeon's English dub of Heartcatch Pretty Cure!, and Nickelodeon's revival of Winx Club. Jay Mastori worked as a creative director and writer for the HeartCatch dub before eventually deciding to move on to another series, after Nickelodeon's English dub of Suite Pretty Cure ended in 2012, which caused the English dubs of the Pretty Cure series to enter a dormant state until early 2020.
