The Impossible Man, or more commonly known as Impy, is a character in the Marvel comics. He is an alien with the ability to shape-shift into anything he thinks of, teleport, and some ability to warp reality. he does have the tendency to cause pranks and mischief, mainly towards the Fantastic Four, and even helps some of the Marvel heroes. But despite him trying his best to help the heroes, his "helping" can sometimes lead towards even bigger problems.
The Impossible Man was born on the planet Poppup and is a member of a race of beings who reproduce asexually and could alter their molecularly malleable bodies at will to temporarily assume any shape imaginably. Popup was a particularly harsh and dangerous world, and the Poppupians' shape-changing abilities enabled them to survive its many perils. By the time of the Impossible Man's birth, the Poppupians had evolved a collective consciousness, linking the minds of the entire race in a group mind. Hence, Poppupians have no names because they were, in effect, all the same being.
Endowed with a slight mental variation that permitted him a degree of individual thought, the Impossible Man acted upon the boredom that his entire race experienced. He did so by transforming himself into a space vessel and leaving Poppup. Eventually he arrived on Earth, and found the planet to provide a great source of amusement potential, especially since he had shape-changing powers and ordinary human beings did not. It was during this first visit to Earth that he first met the Fantastic Four and that he was dubbed "the Impossible Man" after the Thing commented on how the absurd ways that the alien used his shape-shifting powers made him "impossible." The Impossible Man made a major nuisance of himself until the Fantastic Four pretended to be bored with him, and persuaded other people to act the same way. Convinced that Earth was dull, the Impossible Man departed
After touring other inhabited worlds, the Impossible Man returned to Poppup to share his experiences with his people. When the world-devouring Galactus threatened to consume other inhabited worlds, the Poppupians sent the Impossible Man to lead him to their world, which Galactus then consumed. Bored by existence to the point of despair, the Poppupians welcomed the death of their world and their physical bodies. With the Impossible Man's survival, the minds and souls of the Poppupian race would live on in the person of their most adventurous member.
The Impossible Man accompanied the Fantastic Four back to Earth, where he became fascinated by Earth's popular culture. At first he became jealous that he did not have his own comic book and went on a rampage at the Marvel Comics offices until Stan Lee agreed to have at least a single comic featuring the Impossible Man. Observing the feelings of the Thing and his then-girlfriend Alicia Masters for each other, as well as the emotions of others, the Impossible Man learned the human concept of love. Lonely for someone else like him to share love with, the Impossible Man cloned himself a mate, the Impossible Woman, from his own body. The two aliens then left Earth to explore the frontiers of love and to recreate the Poppupian race.
The Impossible Man and Impossible Woman each cloned many offspring from themselves. Eventually, however, the Impossible Man returned to Earth, where he asserted that his mate and their children had all developed minds unlike his own, and that the question had arisen as to who should lead these new Poppupians. The Impossible Man said that to prove his own worthiness, he agreed to compete in a large-scale "scavenger hunt," in which he accumulated many items connected with the super-powered beings of Earth. However, the Impossible Man was judged to have lost the contest. (Whether the Impossible Man was telling the truth about his family and his reasons for the scavenger hunt is not known.)
The Impossible Man reappeared to defend Earth from the Chaos King during the Chaos War, and was brutally slaughtered by the dark god for this.
The Impossible Man's personality is one of a school boy who will go out of his way to prank other people and make them look stupid.
