Other examples of this Tolkien archetype are Tom Bombadil, Treebeard, Radagast and even, to some extent, Aragorn.

In naming his character, Tolkien used beorn, an Old English word for bear, which later came to mean man and warrior (with implications of freeman and nobleman in Anglo-Saxon society). It is related to the Scandinavian names Björn (Swedish and Icelandic) and Bjørn (Norwegian and Danish), meaning bear (the word baron is indirectly related to beorn). Beorn also one of many characters in Middle-Earth who are capable of devoting themselves to a just cause when the time is right, while preserving an aura of danger, self-sufficiency and freedom of choice. Whilst, shape-shifting tendencies aside, Beorn appears at first to be a relatively straightforward character from a children’s novel, he exemplifies a mass of complexities and tensions typical of much of Tolkien’s creative output. His peculiar gift is that he is a ‘skin changer’: that is, he can assume the appearance of a great black bear when the mood takes him.

In The Hobbit, the character of Beorn is described as a huge, black-bearded man who wears a coarse wool tunic and is armed with a woodsman’s axe.
