The Cave Bear was a giant monster seen on Skull Island in the 1933 film Son of Kong. The beast appears just after Carl Denham and Hilda discovered Kiko.
Just after saving Kiko from the quicksand in which the beast was stuck, Denham and Hilda are attacked by a giant cave bear. As the bear charges, Denham fires a shot, causing the bear to stumble before quickly regaining its bearings and continuing its attack. Denham and Hilda manage to climb onto a cliff, but the bear appears able to reach them. Just before making it to the top of the cliff, Kiko saves them, fighting and eventually defeating the beast.
