Jason is a martial artist from the fictional town of Angel Grove, California. At the beginning of "Mighty Morphin Power Rangers", he and his closest friends Zack Taylor, Billy Cranston, Trini Kwan and Kimberly Hart are selected by Zordon and Alpha 5 as the five "teenagers with attitude" to become the original Power Rangers and defend Earth from the forces of the evil Rita Repulsa. When Zordon first confronts the teens to give them their powers, Jason is the only one who initially believes him. Jason becomes the Red Power Ranger and is given the Dinozord Power Coin of the Tyrannosaurus, obtains the Tyrannosaurus Dinozord (a colossal assault vehicle) and is made the team leader. He leads the Rangers into many battles against Rita's monsters, establishing a rivalry with Rita's number one henchman Goldar.
