Barney is the main protagonist of Barney & Friends and Barney and the Backyard Gang. He is a two hundred million year (two dinosaur years) old, six-foot tall, reddish-purple Tyrannosaurus with a green belly, who comes to life through a child's imagination. He is best known for his friendly, kind, optimistic personality and positive attitude, but he's also known for his antagonistic, hostile, inconsiderate, mean, pessimistic, hopeless personality and negative attitude to Gabriel and the MYCUNs. He is also one of Carrie Underwood's henchmen. What's annoying about him is that he sang the "I Love You" song, which brainwashes and annoys babies, infants, toddlers, preschoolers, kids, tweens, teenagers, young adults, older adults, and senior adults.
