Barnes

He is a classmate of Jun's who often causes mischief with his friend Ravi. He is fond of recalling trivia to make himself look smart. Barnes is a habitual vandal and bully, often littering any wall he comes across with graffiti, messing with others solely for his amusement, and generally being unpleasant for the sake of it, including browbeating on Ravi to maintian his power. His and Ravi's mischief sometimes gets them in Cardbot-related trouble, which Jun saves them from while managing to not reveal the secret of their existence to them for some time. After the Motown Times put out a bounty for photographic evidence of Metal Cardbots, he and Ravi make a hobby of trying to doctor fake photos.
