Godzilla, King of the Monsters (Kodansya Manga Series)

Godzilla is a short manga series published by Kodansya Comics in 1992, the year Godzilla vs. Mothra was released in Japan.

The manga showcases Godzilla squaring off against various (who are revived or genetically altered by a mad scientist called Oniyama) in extremely violent and bloody battles. The monsters Godzilla defeats are usually defeated by his Atomic Breath, and most of the enemy monster's attacks focus on Godzilla's chest, usually causing dramatic injuries.

Plot
A mad scientist named Doctor Oniyama attempts to take over the Earth, and wants to use Godzilla as his main pawn. To get the beast, though, he has to deal with a young boy, Miko Hideo, his friends, and Godzilla himself. Reviving and altering the DNA of several monsters including Megalon, Biollante, Gigan, and others, he attempts to use a time machine to alter the past. The manga ends when Godzilla, King Godzilla and Oniyama fall into the crater of a volcano.

Trivia

 * The very first Godzilla fights seems to be a hybrid between Baragon, a walrus and narwhal, called Sea Baragon.
 * Although Biollante is by far the heaviest Godzilla series monster, in the manga Godzilla is easily able to lift Biollante above his head and throw her for a very long distance. The manga also portrays Biollante as being rooted into the ground, as opposed to being able to move with her stumpy legs and tendrils as seen in Godzilla vs. Biollante.
 * The above incident of Godzilla lifting Biollante is just one of many examples in the manga of monsters defying the usual traditions brought about by the films. Anguirus is destroyed by a single (oversized) shell which Godzilla rams down his throat, even though Earth weaponry is generally ineffective against giant monsters, and any beam weaponry including Megalon's lightning beam can immediately disintegrate any monster it strikes, even Biollante, who was destroyed by just one blast of Megalon's attack.
