Bio: An orphaned child living ni the arctic, Koonak was provided
for by Victor Fries. Despite knowing of his alias as Mr. Freeze, Koonak
saw Victor as a loving father figure and was upset with him after he
found what Freeze was going to do to Barbara Gordon.
After the drilling platform exploded, Koonak, along with Nora Fries, was
rescued by Batman and Robin. It is unknown what happened to Koonak.
Note: Koonak later appeared in the back-up to
Batman Adventures #15,
where it's revealed that he lives in an orphanage.
