Omni-morph Duplication:The Absorbing Man possesses the ability to bodily duplicate at will the physical properties of anything he touches or that touches him. This power extends to both animate and inanimate objects and certain forms of energy. The matter of the Absorbing Man's body magically a material and physiological change so that his body actually becomes composed of the matter or energy with which he is making contact. While he is in this altered state, he still possesses his sentience despite the fact that his brain is now composed of the same material as the rest of him. Among the more ordinary materials he has been transformed into include steel, stone, wood and glass. More unusual have been his transformations into water, fire, snow and silk. His most powerful transformations have been into energy-states such as cosmic, nuclear, thermal or light.^{[citation needed]}

The Absorbing Man has learned through practice to only absorb the properties of objects that he wishes to absorb. Originally he could be tricked into absorbing the properties of objects that would render him relatively vulnerable. There appears to be no time limit to how long he can retain a given property. When he is rendered unconscious or in a coma, he retains the form which he last consciously assumed. There would also not appear to be a minimum amount of time he must retain one form before assuming another. He can even become more than one substance at once
