The leader of Yeti Squadron and ice arts adept, FrostNova is considered by many to be Tallullah's equal in terms of temperature control as she is able to turn several city blocks into an icy wasteland within minutes. This kind of power ultimately comes at the price of physical exertion, which manifests as prolonged bouts of asthmatic and bronchial reactions, though few exist who live longer than a few minutes of exposure to her assault.

Much like her art of her choice, FrostNova is a cold-hearted and unflinching member of Reunion, carrying out suppression and extermination detail during and following Reunion attacks. She is also the adopted daughter of the enigmatic Patriot, a prior native of Ursus and current defensive member of Reunion, who took her in following the death of her parents and subsequent entry into Reunion.
