Cyborg Kuro-chan (サイボーグクロちゃん, Saibōgu Kurochan) is a Japanese children's manga series created by Naoki Yokouchi [ja], serialized in Kodansha's Comic BomBom magazine.

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 has many allies, who help him out during instances such as urban destruction, parallel universes, outer space, and battles between other cats and cyborgs.

[3][4] 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.

Kuro is then kidnapped by Dr. Go, a mad scientist, and transformed into a cyborg with invincible steel frames and unlimited strength, the latest in a line of robot cats used for world domination, called the "Nyan-Nyan Army".

He somehow, though, breaks a chip supposedly used to control him, and he escapes Go's laboratory as well as destroying it, while he now realizes that he is now bipedal and can speak human language.

However, Go feels that Kuro is ungrateful to him, and he and the Nyan-Nyan Army, including the most well-known Mi, set out to find and kill him, though they eventually surrender and decide to live a more peaceful life.

The Italia 1 airing had an Italian opening that was sung by regular contributor Cristina D'Avena and Giorgio Vanni, titled "Roba da gatti".

No DVDs or Blu-rays have been released in Japan, likely due to licensing issues regarding the defunct production companies.

[47] Demay felt that the fifth volume, taking place in an alternate dimension, was a chance for Yokouchi to renew himself and to have a change of scenery, and noted that the backgrounds in this sequence are more detailed than usual.

[55] The reviewer for Manga-News noted that although the fifth volume concerned a more serious initial scenario and could be read independently of the others, that the storyline was more of the same silly humor and exaggerated violence.

[57] In the seventh volume, there is a fight between Suzuki's students and Kuro in the desert, which the reviewer for Manga-News describes as inappropriate.
