Denver is the main protagonist of Denver the Last Dinosaur. He is a green Corythosaurus who is the last of his kind. He first met Wally, Shades, Jeremy, and Mario when he hatched from his egg when the boys hid behind a fence in the tar pit from Nick and his friends. He surprisingly understands English. Denver got his name when the kids spotted an advertisement for the city of Denver on the side of a bus. He is known as the last dinosaur.
Denver mostly hangs out with Wally. Denver knows how to play electric guitar and ride skateboards. These abilities led him to be captured by Morton Fizzback, who wanted him so he can be rich. Luckily, the kids found him and rescued him from Fizzback. From then on the kids do everything they can to keep Denver out of sight so people won't try to take him away from them.
