Dexter was once a bumbling T-Rex during the Late Cretaceous period, known for his clumsiness and tendency to trip over his own feet. However, after a strange encounter with a potion, Dexter was brought back to life as a skeletal Throw-Ra with a new lease on life. Despite his past clumsiness, Dexter found a love for the game of football and joined the Fossil Fuelers. Although his size and strength were a major asset, Dexter's clumsiness often caused him to fumble the ball or trip over his own feet. Despite this, Dexter never gave up and worked hard to improve himself, becoming a fan favorite for his determination and never-say-die attitude. His heart and effort on the field earned him the nickname "The Comeback King," as he constantly amazed audiences with his ability to turn his mistakes into incredible "Hail Mary" plays.
