Emma Frost is a mutant who possesses various telepathic talents. Emma can read minds and project her thoughts into the minds of others, project psionic force bolts which have no physical effects but which can affect a victim's mind so as to cause the victim pain or unconsciousness, and can also induce mental pain merely by touching the brow of her victim. Emma can telepathically "sedate" her victims so that, if already rendered unconscious, they remain so for as long as she continues to "sedate" them. It is unknown how effective her "sedating" ability is on victims who are awake.
Furthermore, as a consequence of continued mutation, Emma can now transform her skin and hair into a diamond-hard form at will. In this form, Emma is nigh indestructible except for one small flaw that, if exploited, can cause her to shatter. Whilst in her diamond form, Emma's telepathic abilities are suppressed.
