What do we know about beorn's character so far?

Answer 1

Beorn had a handful of his own animals at his command and were trained, he could turn in to an animal himself and let Bilbo and his companions stay at his home outside the borders of Mirkwood. He went outside at night to keep watch whilst the companions slept. He cares for his animals more than anything, he lets the companions borrow horses but followed them in the shadows when they were on their way to Mirkwood, where the companions would let the horses go back to Beorn's home and Beorn followed his animals back.
