The Bear is the tertiary antagonist of the 1981 film "The Fox and the Hound" and was animated by Glen Keane.
He is a giant black furred bear who will kill anyone who trespasses in his territory. Although he is an antagonist he is not a true villain he is merely protecting his territory.
The Bear first appears while Copper and Amos are trespassing in the woods to find Tod and Vixey, but while trying to get them, they accidentally antagonize the wrathful beast, that awakens and attacks Copper's owner. He swipes at Amos, causing him to tumble down a hillside, and the Bear continues to pursue him. Whilst trying his best to escape from the Bear, Amos is caught in one of his own traps and his gun is caught on a tree. Furious that the intruders aren't leaving his territory, the grizzly continues to attack them. Copper bravely tries to protect his master and attacks the Bear, but despite of being small and more agile, he is no match to the giant bear, and Copper is soon overwhelmed in a very vicious fight. Against his better judgement, Tod quickly intervenes to save his friend. He fights the much larger bear and ends up luring him up on a fallen trunk. While Tod hangs for dear life on the trunk, the Bear tries to deliver the final blow but misses and accidentally spilters the log, sending the two animals falling down into the huge waterfall many meters below. Tod survives while the Bear is presumed dead.
