This short, four page, single-volume promotional comic was produced by Cinema Shares International Distribution Corporation and was issued in 1976, to coincide with the release of Godzilla vs. Megalon in American cinemas later that year. Although the comic's plot roughly follows that of the film, there are several significant differences present.
The story is credited to R.J. Wilson and the art was done by "Swiftspear."
Megalon appears during an undersea eruption and attacks an unnamed city. Meanwhile, Godzilla learns of this and calls on Jet Jaguar to come and help him, then travels to fight Megalon, who now has partnered with Gigan. Megalon, Gigan and Godzilla fight, and then Jet Jaguar arrives to help. Ultimately, Gigan is defeated after Jet Jaguar picks him up and drops him from a great height, and Megalon suffers a painful death after Godzilla bites into the back of his neck.
Differences between the movie and the comic.
- Megalon is shown not to be Seatopian in origin, and appears during the midst of a large undersea volcano's eruption. Rather than leading an invasion force, Megalon simply attacks cities to satisfy his 'Energy Hunger'.
- The M Space Hunter Nebula Aliens are not described as giving Gigan to help Megalon, and Megalon simply allies with Gigan, who presumably was already on Earth.
- Jet Jaguar, despite being able to travel faster than Godzilla, arrives later in the fight than Godzilla. In addition, Godzilla calls on Jaguar to help fight Megalon, rather than Jaguar coming to Monster Island to ask Godzilla for help. In addition, the comic ignores the fact that Gigan can fly, and would be able to escape being killed by Jet Jaguar by swooping back upwards as he approached the ground.
- Both Gigan and Megalon die rather than escaping the fight.
- Jet Jaguar and Gigan's names are changed to be "Robotman" and "Borodan," respectively.
- This is the first American comic to be made of Godzilla.
- The comic is also featured in an issue of G-Fan Magazine.
