Godzilla vs. Megalon (Comic)

The Godzilla vs. Megalon promotional comic is a short, single-volume comic produced by Cinema Shares international Distribution Corporation that was issued in 1973, to coincide with the release of Godzilla vs. Megalon in American Cinemas. Although the Comic's plot roughly follows that of the film, there are several significant differences present.

Synopsis
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 comic and the film

 * 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 Nebula M Spacehunters 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.
 * Both Gigan and Megalon die rather than escaping the fight.
 * Jet Jaguar and Gigan's names are changed to be 'Robotman' and 'Borodan', respectively.
