Billy Cranston (World of the Coinless)

Billy Cranston was the Blue Ranger of the Mighty Morphin Power Rangers and followed his counterpart's original timeline, until the Green Ranger's full defection to the side of evil.

History
Billy Cranston was chosen by Zordon to be the Blue Ranger.He fought with the Power Rangers against Rita Repulsa and her monsters.

As Billy continued to fight among the Rangers, they came under attack by Rita's new Green Ranger. They were able to break the spell that held him under Rita's sway by destroying the Sword of Darkness. However, Tommy still chose to align with Rita and they began to conquer the Earth. Together with allies new and old, Billy fought to keep their forces back. Zordon creates the Unicorn Thunderzord for him. However, it is not enough. Billy dies in the ensuing battle, but not before hiding his Triceratops Power Coin with Trini.

Billy is loved and remembered by The Coinless, who keep his photo at the base. The Power Coin he left began to be referred to as "The Relic". Trini held on to it, and this prevented Drakkon from creating an army of Triceratops Sentries as well. Eventually, Trini and Billy from the original timeline are able to use the coin to depower Lord Drakkon and his sentries, ensuring victory, at least for a time.
