Plastic Man - Weaknesses

Weaknesses

His semi-liquid form remains stable at relatively high and low temperatures, provided that the temperature change is gradual. A sudden change induces a complete change of state, creating a truly solid or truly liquid form. Plastic Man was incapacitated in the JLA story arc "Tower of Babel" when mercenaries froze and shattered his body. Once thawed and reassembled, he was physically unharmed (though emotionally traumatized). In the JLA story arc "Divided We Fall", Plastic Man is shown to have some weakness to extreme heat (intense heat vision attack from a martian) and was temporarily melted. In some versions, Plastic Man is also vulnerable to chemicals such as acetone, which melts and destabilizes his putty-like form, although he will eventually regenerate when the chemicals are gone. Another weakness is that the only colors Plastic Man can mimic are the colors of his body and costume (IE: red, black, yellow, and flesh tone), although he can use these colours in various ways, once even managing to exactly duplicate the appearance of the Flash. Whether this is an inherent flaw in his powers or a mental block had never been explained, whereas, his son, Offspring, also gained his father's powers, but is able to mimic any color he chooses; Offspring's introduction revealed that Plastic Man could change color, turning his nose blue to prove to Batman that he could, but it apparently took a great deal of concentration just to accomplish that much. Also, for a long while it was not known if Plas could take off his costume, but when he rejoined civilian life, he was wearing normal clothing so it appeared that he is able to.
