Along with the TV series, a new manga, Shin Mazinger Zero started on April 18, 2009 (2009-04-18) (cover date June 2009 (2009-06)) in the magazine Champion Red.

During all of this, Juzo's grandchildren, Kouji and Shiro, encounter one of Baron Ashura's robots on its way to attack Dr. Kabuto's mansion, where he has begun work on his greatest invention.

Dr. Kabuto, seeing the danger at hand, sends out the Pilder to Kouji, allowing him to combine with the giant robot, Mazinger Z, to fight against Dr. Hell's forces.

Along with the TV Tokyo broadcast, a web stream that uses the mms protocol is available in the Bandai Channel exclusively for Japanese users.

Source(s)[6][7] Besides the several video on demand internet services that show the Bandai Channel stream freely in Japan, the series will be released in both DVD and Blu-ray formats.

Written by Yoshiaki Tabata with art by Yuki Yogo, it is an original production which takes elements from several past versions of the Mazinger concept.

The plot deals with Humanity being destroyed by an evil Mazinger Z. Koji Kabuto, the last man alive, is killed by a human-sized, human-looking Minerva X so his spirit can travel back in time to prevent the disaster—but it takes several tries.

Shin Mazinger Zero also includes guest stars from Nagai's more risqué works, such as the nude warrior Kekko Kamen, and as such, contains high-levels of gore and sexual content.

Chapter H") is a special one-shot sexy gag comedy done by Go Nagai and published in the magazine Champion Red Ichigo on August 19, 2009 (2009-08-19) (cover date October 2009 (2009-10)).
