Fictional characters with ice or cold abilities

Must be a defining trait - Characters with access to vast powers (i.e. magical spells, advanced technology, genetic engineering, etc.) who are theoretically capable of this superhuman feature or ability - but whom have neither made regular use, nor provided a notable example, of this extraordinary or supernatural feat - are not listed here. This category is for listing fictional characters that have cryokinetic abilities related to ice or cold. This includes the ability to control the thermokinetic energy of atoms to generate, control or absorb ice.
