The Poppupians are the race of beings who spawned the Impossible Man. They lived in the tenth galaxy. The Poppupians can change into anything by merely thinking about it, thus saving themselves from the vicious Urrpo fish who live there. They can change into spaceships and fly to any planet they want.
In one such case the Impossible Man flew to Earth to see if it was a good vacation spot. He knew none of our customs and caused much panic until Reed Richards said to simply ignore him and he left. When Galactus consumed their world after they had infused their essences into the far-away Impossible Man, they nearly killed Galactus with indigestion.
The Poppupians would send their ambassador the Impossible Man to Earth. He would make the mistake of asking to be taken to the planets leader. This leader happened to be the mad mutant Apocalypse who would turn Impossible Man over to the Dark Beast for experimentation. When the X-Man Blink would come across the Impossible Man, she would blink him away to put him out of his misery.
