Kurrgo
Kurrgo was the leader of the Xantha people of Xanth.[1] When the planet was threatened by an incoming asteroid, Kurrgo convinced the Fantastic Four to save his people. Mr. Fantastic, Reed Richards, developed a shrinking gas that allowed all of the planet's five-billion people onto a single spaceship, allowing them to escape and find a new home. Richards also gave Kurrgo a vial supposedly containing an enlarging gas to return them to normal when they colonized a new planet. But as Xanth began to crumble and the citizens escaped, Kurrgo held firm to the large vial, intent on enlarging only himself when they reached a new planet so that he would be an unstoppable ruler of his people. The vial slowed him down to the point that he failed to reach the ship, seemingly perishing along with Xanth.[2]
