Bugbear

Neither bugs nor bears, bugbears are the hulking cousins of goblins and hobgoblins. With roots in the Feywild, early bugbears resided in hidden places, in hard-to-reach and shadowed spaces. Long ago and from out of the corner of your eye, they came to the Overworld. Centuries later, they still bear a fey gift for lurking just out of sight.
They are long of limb and covered in coarse hair, with wedge-shaped ears and pointed teeth. Despite their formidable build, bugbears are quiet skulkers, thanks to a fey magic that allows them to hide in spaces seemingly too small for them.
