Challengers of the Unknown
Storyline
The Challengers are transported to Challenger Mountain in the year 2265 where the Godzilla-like Monstro, is ravaging domed cities. Monstro was shot to Earth in 1900, hatched in 1965, bored to the Earth's core to incubate, and returned to the surface in 2265. The Challengers must kill Monstro in 1965. Returned to their own time, the heroes don asbestos suits and follow the egg into the Earth. Baby Monstro emerges, but grenades can't kill it, and the monster bores deeper where it's too hot to go.
