Notchka and Shaka are Mister Freeze's loyal pet polar bears from the film Batman & Mr. Freeze: SubZero.
History[]
Notchka and Shaka were polar bears adopted by Mr. Freeze while attempting to cure his wife Nora in an arctic cave. The bears were loyal to their master, assisting him and digging him out from rubble when a submarine crashed into their cave. Freeze later brought them to Gotham where they aided him in trying to kidnap Barbara Gordon to use as an unwilling organ donor for Nora.
