This is fan novelization of a hypothetical sequel for UFO Robo Grendizer
One of the first Super Robot manga and the one that introduced most of the traits of the Mecha genre. Constructed with the Super-Alloy Z, Mazinger was built by Professor Juzo Kabuto as a weapon against the Mechanical Beasts of the evil Dr. Hell. Koji Kabuto, the grandson of Professor Kabuto, becomes the pilot of Mazinger Z when his grandfather is killed, and battles from there on against Dr. Hell and his allies. This is the first series that introduced the concept of a pilot inside a Mecha, which all series from then on have followed.
Great Mazinger starts after the defeat of Mazinger Z. Tetsuya Tsurugi is the new protagonist, piloting the powerful Great Mazinger, a creation of the once thought dead Kenzo Kabuto, the father of Koji Kabuto. This time the enemy is the Mycene Empire and its powerful robots.

Tetsuya Tsurugi is the new protagonist, piloting the powerful Great Mazinger, a creation of the once thought dead Kenzo Kabuto, the father of Koji Kabuto.

MazinSaga is a manga written and produced by Go Nagai between 1990 and 1998; currently on going again, it's the summa of Nagai's works, for the complexity of the plot and the treated thematic content. Mazinsaga tells the story of the young Koji Kabuto, university student who finds himself having to collect the fruit of the researches of his father, physicist of world-wide reputation who died in mysterious circumstances. The boy is thus given a powerful artefact, Mazinger Z, the Armor of God.
The ultimate cross over manga featuring Mazinger Z, Great Mazinger, Grendizer, Getter Robo, Getter Robo G and Jeeg! These all-stars band together in order to defend Earth from cosmic evil. This manga is in the same vein as all those old Toei cross over movies, and the self-parody gets pretty strong later on.
Mazinger Angels chronicles the adventures of four women who pilot giant robots in the Mazinger vein. The concept is a spoof on the late 70's and early 80's popular TV series Charlie's Angels. Three of the robots, Aphrodite A, Diana A and Minerva X are from the original Mazinger Z series, while Venus A is from the Great Mazinger series. Their pilots are also traditional characters from Go Nagai's universe, Sayaka Yumi and Jun Hono from Mazinger Z and Great Mazinger respectively, and Hikaru Makiba and Maria Fleed from Grendizer. The style of the manga highlights the sex appeal of both the characters and the mechas, sometimes similarly to the way Aika's female characters are shown. (Source: Wikipedia)
