Barnaby Brooks Jr., also known as "King of Heroes," is a new hero on Hero TV who partners with Wild Tiger. Unlike his partner, Barnaby relies more on strategy than force and is seen as cool and handsome by many people. He is currently the top-notch hero and has earned fame for his points in his career. Initially, Barnaby acted only for the fame and points but was eventually broken from his stoic demeanor by Kotetsu. Despite this, Barnaby cares about others, such as his nanny who bakes him a cake every year for his birthday. After Jake's arrest, Barnaby is shown more frequently with a smile and seems to enjoy himself more often. Though he still cares about the points, he argues less and works well with Kotetsu.
He appears to be very emotionaly unstable and suffers emotional and mental breakdowns due to the death of his parents as well as the false memories that were implanted into him by Albert Maverick.
It was revealed in "Tiger & Bunny Movie 2: The Rising" that he actually cared about the money given from HERO TV because Barnaby donates to charity and takes the kids out due to his emotionally tragic past regarding his parents, plus implies he has the same reasons as Kotetsu for being a hero.
