Mordenkainen Presents: Monsters of the Multiverse

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 Material Plane, urged to spread throughout the multiverse by the conquering god Maglubiyet. Centuries later, they still bear a fey gift for lurking just out of sight, and many of them have sneaked away from that god’s influence.

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.

Volo's Guide to Monsters

Bugbears rely on stealth and strength to attack, preferring to operate at night. When they're not in battle, bugbears spend much of their time resting or dozing, and bully weaker creatures into doing their bidding. From the viewpoint of the rest of the world, their aggression and savagery are thankfully offset by their rarity and lethargy.
