Coldheart using her cryokinesis

Coldheart using her cryokinesis to freeze her opponents hands

Coldheart had cryokinetic abilities, but whether they stemmed from her body naturally, an augmentation or just her armor or swords is unknown.


She was a highly skilled martial artist and swordsman.


Coldheart had a flawed sense of logic that superheroes were all villains, and each one was responsible for her son's death. This did not seem to be present after her escape from the Raft, showing far less hostility and even some fear towards costumed heroes.



Coldheart wore a bulletproof state-of-the-art armored costume whose full abilities were unspecified.


Coldheart wielded twin swords capable of producing energy that paralyed with the touch of the blade, or could be projected to freeze objects instantly. Spider-Man stated that he was frozen in place from her paralysis ability, which still points to the energy being cryokinetic.


  • Despite being a supervillainess, Coldheart only ever fought a superhero (Spider-Man) once.
