Billy Cranston is the genius Blue Ranger of the Mighty Morphin Power Rangers.
Billy was chosen by Zordon to wield the power of the Triceratops Power Coin to become the Blue Power Ranger. Despite his superior intellect, Billy has long since felt self conscious about his lack of athletic ability compared to the rest of the team, as well as his role as a hero.
The tension between Tommy and the rest of the team, continues to rise, culminating in a great argument between them. This is interrupted by a new enemy, calling himself the Black Dragon attacked the Command Center directly. The building was crumbled and their robot compatriot, Alpha 5, was badly damaged. The group of six rangers took strike against the enemy, whose power seemingly affected their own, causing their unmorphed bodies to temporarily become exposed through their suits. Not able to stand up to the powerful creature, Jason and Trini set up teleportation to a pocket dimension for safety. Just as the teleportation sequence was initiated, Billy was pulled from the ray of blue light and knocked unconscious as his friends escaped. The Black Dragon uses his Power Coin to connect to the Morphing Grid and causes the other four to lose their powers.
Trapped in the Dark Dimension, Billy finds himself in the company of Goldar whom is being punished for his failure in the aftermath of Tommy's joining of the Power Rangers. Eventually, the two are able come to an understanding and Billy is able to escape in time to help Tommy defeat the Black Dragon, which he reveals to be mechanical much like of his zords. The two unmorphed rangers destroy the power source, but find themselves trapped in its rapidly shrinking body.
