Impossible Man

When the Impossible Man first appeared, the character differed from previous guest stars in that he was not a villain. The team first meet him at the Flamingo restaurant when they are summoned there to investigate a disturbance. Written by Lee to be a prankster and hedonist, the Impossible Man claimed to belong to the alien race of Poppupians from planet Poppup in the 'Tenth Galaxy', who all share a collective consciousness and the ability to shapeshift, as their planet is so dangerous they have the ability to evolve very quickly. Seeking amusement, the character visits Earth for a vacation by turning himself into a spaceship, talking of a Poppup Tourist Bureau. After finding the superhero team the Fantastic Four and realizing nobody else on Earth has his power (therefore concluding he is the most powerful being on Earth), he constantly harasses them until they decide to ignore him and tell other people to do the same, forcing the Impossible Man to leave as he finds Earth so boring, and saying Earth will never get their tourist business. He gets his name after the Thing claims he is "impossible".
