Impossible Man's powers and abilities
The Impossible Man, like all Poppupians, has the ability to rearrange the molecules of his body at will into any form he chooses. He can simulate some of the abilities and functions of the object or living being he imitates, depending on what that object or being is. For example, He can become a working electric fan, water hose, or jet-propelled engine (although they empower these objects by their own molecular energies rather than by electricity, water, or jet fuel). However, if he imitates an object such as Thor's enchanted uru hammer, Captain America's vibranium-adamantium shield, or the Silver Surfer's cosmic surfboard, he can only take on the appearance of said objects, and not their special properties. The degree to which he can imitate the superhuman powers of other beings is unknown.
The Impossible Man can even separate himself into various parts in changing form, such as when he becomes a large number of flowers, or when he becomes a bag of water, which then spills its contents. He retains his full consciousness in whatever form he takes, and can control all the parts into which he divides, and reassemble them into his own single, natural form.
The Impossible Man can temporarily discard unnecessary molecules of his bodies when imitating objects or beings of considerably less mass than his own: a fountain pen or a hat, for example. (He customarily disperses his spare molecules over a large enough area that they cannot be discerned, and regains them on returning to his original form.) He can also draw additional molecules from an undisclosed, perhaps extradimensional, source to increase his size. In order to clone the Impossible Woman from his own body, for example, the Impossible Man had to draw enough additional molecules to create a being from himself who had the same amount of mass as he did. There are apparently limits to the amount of mass that he can temporarily add to his own at any one time. It has been theorized that the Impossible Man employed technology to help him impersonate the gigantic Galactus on one occasion. (It is also theorized that he employed technology to teleport many of the items,' some of them enormous, that he gathered in his "scavenger hunt" to different locations.)
The Impossible Man's transformations occur within a fraction of a second, and are accompanied by a "pop" sound.
The Impossible Man and Impossible Woman can travel through hyperspace by transforming themselves into an imitation of a starship. They can survive in the vacuum of space for months without food, water, or oxygen by inducing in themselves a low metabolic state similar to hibernation. (During that time, if they are in starship form, their subconscious will guide them to their destination.)
