Bernardo Bernstein, nicknamed Bear by friends and Bernardinho by his mother, is an 11-year-old student at Springdale Elementary living in Seaside Town's Flower Hill neighborhood. He sports a robust build, distinctive rings under his eyes, spiky black hair, and usually a plaster on his left cheek. His typical outfit—a blue varsity jacket with white sleeves, a white shirt featuring a triangular design, brown shorts, and white sneakers—creates an initially intimidating look that belies his true nature. Despite his thuggish exterior, Bernardo possesses a gentle, sensitive, and somewhat bumbling personality. Highly emotional and prone to bursting into tears, he is also a self-professed glutton lacking athleticism and often displaying clumsiness. His sensitivity fuels a pronounced fear of his frequently scolding mother, Mrs. Barbosa (Sra. Barbosa), and he finds Eddie's mother even more intimidating. Bernardo exhibits a simple yet deeply loyal nature, especially toward close friends Nate, Katie, and Eddie. Family significantly impacts his life. Alongside his dominant mother, he has a younger sister, Bernarda (sometimes called Bearmie), who lives in America with her boyfriend Arnold. Bernarda appears in the anime during her return from a visit to BBQ. Bernardo's father is mentioned across media but remains unnamed. Bernardo shares in various misadventures with his friends throughout the franchise. In the games, quests include "The Ring In The Pond," where he asks Nate to retrieve his parents' lost engagement ring, and "The Extreme Dare," which sees him trapped by Yo-kai Rattelle after accidentally taking one of her rib bones. A series of "Yo-kai Watch 2" quests ("Bear Boy - Origins," "The Bear Boy Returns," and "Ultimate Bear Boy") depict his comedic attempts to become a superhero, invariably ending in chaos and maternal reprimands, highlighting his gullibility and recurring misfortunes. The anime and films reinforce his established traits. "The Movie" features him discussing bizarre occurrences of objects enlarging with Nate, Katie, and Eddie. "The Great Adventure of the Flying Whale & the Double World, Nyan!" includes live-action segments where actor Yu Sawabe portrays Bernardo as a 30-year-old man—a detail Nate humorously notes. Here, Bernardo obtains a rare Emperor Krills toy and naively negotiates its sale with Eddie. Episode 26 reveals his crush on classmate Lulu when Katie is inspirited by Yo-kai Ciclopina (Espy). Trivia notes his nickname "Bear," alongside his surname "Bernstein," references "The Berenstain Bears" franchise. Compared to his friends, he experiences the fewest instances of being inspirited by Yo-kai. References in later media like "Yo-kai Watch Shadowside" suggest he may have moved away from Springdale, though his whereabouts remain unconfirmed.
