Cyborg Kuro-chan (サイボーグクロちゃん, Saibōgu Kurochan) is a shōnen manga series created by Naoki Yokouchi, serialized in Kodansha's Comic BonBon magazine. Eleven volumes of the manga were released between 1998 and 2002. It centers on the titular character, a housecat who is kidnapped and modified by a mad scientist to be a part of a cyborg army bent on world domination. Kuro breaks his control chip, escapes and becomes a vigilante. Kuro has many allies, who help him out during instances such as urban destruction, parallel universes, outer space, and battles between other cats and cyborgs. Cyborg Kuro-chan was adapted into an anime series produced by Tokyo Movie Shinsha for TV Tokyo. The anime aired from 2 October 1999 to 6 January 2001 for 66 episodes. The manga and anime have been exported to several countries in Asia, Europe, and Africa. A large number of merchandise has been made based on the manga and anime, and two additional volumes, entitled Cyborg Kuro-chan: Extra Battle, were published. Reviews for the series note the simplistic and cartoonish art style, and a thin storyline which is mainly centered on gags and comedic violence.
