Cryokinesis

James Walker (Heroes)
James had the ability to freeze objects, which allowed him to reduce the temperature of matter, causing an object to freeze in the process. Sylar found James's name on Chandra's list, then added it to his own list. He went to the Walkers' home, killing James, stealing his ability, then freezing him with his own ability as a means of "practicing".

Tracy Strauss (Heroes)
Tracy possesses the ability to freeze objects which allows her to reduce the temperature of matter at will. She is capable of freezing human beings as well as inanimate objects including a rose, a telephone, and glass.

When using her power, Tracy appears to absorb the heat from an individual instead of emitting cold. Also, while she is able to create sub-zero temperatures, Tracy herself retains body heat.
