Johnson, had a hardy constitution like a rock. When he ran through the dome stadium like a heavy truck, the cheers of his fans and girls, burst out loud. He always led his team to lift the champion's trophies and achieved the peak of his life as a super quarterback, with millions of fans around him. However, fortune is always a fickle. One day, a little girl rushed to the road in a sudden while Johnson was driving his sports car. To avoid hitting the little girl, Johnson drifted his car and crashed severely. A massive brain haemorrhage was about to take away his life in just minutes. At that moment, a miracle occurred; the wreckage of his sports car started to blend into Johnson's body by a mysterious force. Consequently, he not only just survived from the crash, but also became a new mechanical human who could transform into to a sports car, when necessary.
