(Fantastic Four I#7) - The planet Xanth was threatened by a collision with a runaway asteroid--as a result, the world suffered from extreme tides, volcanic instability, and internal rioting. In order to save their people, members of the Xantha race (along with their ruler, Kurrgo) sent a robot in one of their to two spacecrafts to Earth, to capture the Fantastic Four.

   As the ship entered Earth's atmosphere, it was detected by an American satellite, but a squadron of jet interceptors was unsuccessful in halting the spaceship's progress. Once the ship landed, the robot pilot disembarked and projected a hostility ray that caused those affected by it to become extremely angry at the Fantastic Four--the FF were meeting with members of Congress at that time, and the effects of the ray drove the FF out into the open.

   The robot eventually went back aboard the spaceship and began following the Fantastic Four's Fantasticar until they landed atop the Baxter Building. Once it met the team, the robot explained to the FF that since everyone had turned against them, their only asylum would be on the planet of its master, Kurrgo. Out of curiosity, the Fantastic Four agreed to accompany the robot and boarded its ship for a voyage to "Planet X" (Xanth), where they discovered that the Xantha needed their help to prevent the planet's destruction.

   In order to get themselves back to Earth and save the Xantha, Mister Fantastic synthesized the shrinking gas used by Ant-Man (Henry Pym), and used it to reduce the population of the planet so that the Xantha could all fit inside their second spaceship and escape to another planet (see comments), while the Fantastic Four boarded the first ship and returned to Earth.

   As the shrunken Xantha began boarding the spaceship and prepared to evacuate to their new world, Kurrgo was delayed because he was plotting to withhold the enlarging gas (which, unknown to him, was actually an empty canister) from his miniaturized people so that he could rule their new world as a "giant"; but as Xanth crumbled around him, Kurrgo watched the evacuation spaceship take flight, and he realized that his subjects had left him behind.

(Marvel Feature I#11 (fb) ) - With the aid of his robot, Kurrgo escaped Xanth's destruction in a third hidden spaceship; for years, he searched the celestial byways, trying to find his people's new home. He eventually managed to locate New Xanth, where he found that his shrunken people had progressed remarkably in the intervening years--they had built great miniature cities that dotted the landscape. But Kurrgo's former subjects no longer wanted him to rule over them--despite his size advantage, the tiny inhabitants of New Xanth used their miniature weapons to drive Kurrgo and his robot back into space.

Comments: Created by Stan Lee (writer) and Jack Kirby (pencils) & Dick Ayers (inks).

Originally, their world was just called "Planet X" in the two stories they appeared in, and its actual name--Xanth--was not revealed until the Xantha entry in Official Handbook of the Marvel Universe I#12.

Kurrgo mentioned to Mister Fantastic that the population of Planet X was five billion--even at their reduced size, that evacuation spaceship sure must have been crowded.

Considering that he saved everyone on their planet, I'm surprised that New Xantha didn't put in a good word for Reed Richards when he was on trial for sparing the life of Galactus (@ Fantastic Four I#262 )--maybe they hadn't changed their isolationist ways...or maybe they were there, but since they're so small, nobody noticed.--Ron Fredricks
