A Cautus Infected, born to a life of slave-mining in the Ursus tundra, FrostNova is a high-ranking member of Reunion. She leads the fearsome Yeti Squadron for special operations and is one of the few Casters who can suppress enemies in a head-on engagement. Saved by Patriot from her horrific life, FrostNova looks up to him as her father.
Sent by Talulah to attack Lungmen in coalition with Mephisto, they are held off by the combined efforts of Rhodes Island and Lungmen Guard Department before the Black Raincoats sweep in and lead a purge of the Lungmen Infected. With their roles now reversed, FrostNova stays back to help evacuate the slums even as her Oripathy worsens. She eventually confronts Doctor and Amiya who offer her a chance to join Rhodes Island. FrostNova agrees on the condition they beat her, on pretext of testing Amiya's resolve to defeat Talulah.
Following their fateful encounter, the Doctor takes FrostNova's body with them so she could be properly cremated in one of Rhodes Island's incineration chambers as a sign of their honour and respect towards her, now a posthumous member of Rhodes Island.
