Review/plot:
Reed Richards offers SHIELD the solution of sending Godzilla, who is still shrunk down to about 15 feet at this point, back in time using Dr. Doom's time machine. They agree.

In the past, Godzilla teams up with Devil Dinosaur and Moonboy to fight a horde of cavemen and dinosaurs. If only they could have gotten Kirby to draw it.

Meanwhile, it turns out that Doom's time machine was somehow affected by Godzilla's radiation. Reed says that it'll either explode or bring Godzilla back into the present. So the FF do what any responsible people would do, and they drop the time machine in the middle of Times Square.

Godzilla reappears just as SHIELD arrives.

A mega-battle with the Fantastic Four and the Avengers ensues.

Finally, Godzilla is convinced by Robert Takiguchi to just stop fighting and go away, "as far away as you possibly can". Godzilla heads into the ocean, pretty much never to be seen again.

Speaking as a big fan of the 60s and 70s Toho Godzilla films, this series never really lived up to its potential.

Quality Rating: C-

Historical Significance Rating: 1

Chronological Placement Considerations: "Obviously this takes place before the [Avengers] roster shake up in Avengers #181."

The series was cancelled not due to poor sales, but because Toho dramatically increased its licensing fee.

There was a cover by Steve Ditko intended for the Godzilla story later altered for Marvel Spotlight. The cover was first(and only?) published in the Comics Journal, and Godzilla looked a bit...well...puny.
