Barnaby Bernstein, known to all as Bear, stands as one of Nate Adams' closest friends and classmates at Springdale Elementary School, sharing a strong bond with another classmate, Eddie Archer. His rough, intimidating exterior—marked by a sturdy build, dark rings around his eyes, a spiked black hairstyle, and a permanent bandage on his left cheek—belies a gentle, simple, and somewhat bumbling nature. Deeply caring and unusually sensitive, he is quick to burst into tears, even as he proudly claims the title of class punk and prankster. Bear is a self-admitted glutton with little athletic talent and is known to be terrified of his mother, who frequently scolds him for his misadventures. He has a younger sister named Bearmie who lives in America. Across various media, Bear often finds himself at the center of peculiar events. In *Yo-kai Watch*, he enlists help to retrieve his parents' lost engagement ring from a pond, becomes trapped inside an anatomical model by the Yo-kai Rattelle, and seeks aid when a Wazzat causes his mother to forget to make dinner. His adventures continue in *Yo-kai Watch 2*, where he aspires to be a superhero. In "Bear Boy - Origins," a Mochismo-inspired mishap leads him to fall into a river, followed by a scolding from his mother. "The Bear Boy Returns" sees him training at the Springdale Sports Club only to be sped up by Nekidspeed and crash into his mother, while "Ultimate Bear Boy" involves a clash with Eddie under the influence of Supoor Hero, culminating in a rooftop jump and dual maternal reprimands. In *Yo-kai Watch Sangokushi*, he and Eddie are inspirited by an unknown deity, resulting in them eating their ice cream in a strange fashion. The anime features Bear as a recurring character who joins Nate and friends in their adventures, including discussions about bizarre phenomena in *Yo-kai Watch: The Movie*. In the third film, *The Great Adventure of the Flying Whale & the Double World, Nyan!*, a live-action version of Bear wins a rare Emperor Krills toy from a crank-machine; Eddie tries to buy it, but negotiations fail due to insufficient funds, with onlookers noting Bear resembles a 30-year-old man. One episode reveals he has a crush on a girl named Lulu. Bear also appears in *Yo-kai Watch Blasters*, *Yo-kai Watch 3*, and *Yo-kai Watch 4*, though detailed information on his roles in these games is not provided.
