Thunder
Thunder is the official live animal mascot for the Denver Broncos football team. He is a gray horse whose coat has lightened with age until it turned completely white. Thunder has appeared in four Super Bowls and is a fan favorite. He is known for his calm demeanor in situations that would normally frighten most horses, such as being in football stadiums with thousands of cheering fans. Thunder also makes regular appearances in parades, hospital and school visits, and other public functions.
