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. He is responsible for creating the team's communicators, based on Zordon's own technology and regularly performs maintenance on the individual Zords. Despite his confidence in his own superior intellect, Billy feels self-conscious about his lack of athletic ability in comparison to the rest of the team, as well as his role as a hero. In his youth, he was good friends with Eugene 'Skull' Skullovich, though the friendship eventually soured and became more antagonistic. He is a frequent target of Bulk and Skull's bullying.
As tensions rise between Tommy and the rest of the team, a new enemy calling himself the Black Dragon attacked the Command Center directly. Destroying the building and Alpha 5, the group fought a losing battle against the enemy before 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 used his Power Coin to connect to the Morphing Grid and caused 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 the Zords. The two unmorphed rangers destroy the power source, but find themselves trapped in its rapidly shrinking body.
At the last moment, the two escape but find themselves in an alternate future where Tommy never joined the Power Rangers and became an evil white ranger named Lord Drakkon. Escaping from an army of Mastodon Sentries, they find the ruined remains of various Zords and the White Ranger's blade: Saba, who guides the two and explains the history of the worlds formation. Shortly after, the two come into contact with the rebellion; consisting of alternate versions of Zack, Trini, Aisha, Kat and Bulk. Reclaiming his deceased counterparts morpher and coin, Billy feigns surrender to allow Alternate Trini the chance to get close and destroy Lord Drakkon's morpher and coin with it. The rest of the rangers show up in the alternate future to rescue Billy and Tommy, where they use the remainder of the Black Dragon's power to send them all home.
