Emma's diamond body is virtually tireless, as she does not produce fatigue poisons and has no need for water or food. She is also numbed from emotion, pain and empathy, impervious to cold, and resistant to heat in this form. Furthermore, in this form she has no need to breathe. Despite this high level of invulnerability, her diamond form has a single molecular flaw, which, if exploited – such as being shot with a diamond bullet – can cause her body to shatter.
