Billy Cranston


 * For the movie version of this character, see Billy Cranston (movie)

Billy Cranston is a fictional character in the Power Rangers francise. He is the Blue Ranger in the series Mighty Morphin Power Rangers, portrayed by David Yost. Billy is the only original Power Ranger to remain for the entire MMPR series, and is the second longest-serving Ranger overall behind Tommy Oliver. Until his departure, he was considered the brains of the Power Rangers team, creating many gadgets with which to solve problems that not even Zordon foresaw, and even invented the first team's wrist-worn communication devices (it is believed, though not proven, that he created every other communicator up until his departure from the show).

The character was also played by Yost in the unaired pilot. Billy also appears in the video game Power Rangers: Super Legends alongside some of his Ranger teammates and was voiced by Brian Donovan.

Mighty Morphin Era
Billy was one of the five "teenagers with attitude" selected by Zordon to become the original Power Rangers, along with Jason Lee Scott, Zack Taylor, Trini Kwan and Kimberly Hart. Billy became the Blue Mighty Morphin Power Ranger, and was given both the Triceratops Power Coin and the Triceratops Dinozord.

Billy began the series as the stereotypical "nerd." His closest friend throughout the series was Trini, to whom he could communicate most comfortably and effectively. He was initially very insecure about himself, making him an easy target for people like Bulk and Skull, who tormented him often in the beginning. The other Rangers, especially Trini, defended him loyally, but Billy later evolved to become a stronger individual. He was one of the top members of Angel Grove High's science club and often helped its younger members with their experiments. One such example was with Willy, a young boy he helped to create a virtual reality simulator for a Science Fair. In the episode "High Five", Billy not only created the communicators, but also the interface that allowed the devices a remote access to the Command Center's teleportation unit.

It was revealed that, due to an experience in his youth when he was bitten by a fish during an experiment involving whirlpools, Billy developed icthyophobia: fear of fish. This fear would affect him well into his teens and Rita would use a spell to exacerbate this fear. When he was the last Ranger left able to contend with the Goo Fish monster, Billy overcame the spell and then, after helping to free his friends and defeat the monster, completely overcame the fear itself on a fishing trip with Ernie, the owner of the Youth Center.

Each of Billy's teammates had a unique skill to offer the team and, in Billy's case, it was his vast intelligence. He sought out to improve himself physically, and the audience would see him transition over time from the suspenders-wearing "brain" to a confident, hyper-intelligent athlete with appreciable fighting skills, thanks in great part to Trini's Uncle Howard. Jason, and later Tommy, helped graduate Billy to the red belt level in karate.

Billy's intelligence would help the Rangers save the world on many occasions. When the Command Center was damaged, Zordon lost and Alpha incapacitated, it was his invention, the RADBUG that allowed the Rangers to travel to the Command Center. He performed a wide array of tasks, ranging from creating the method for which the Ranger's would use initially to infiltrate Rita's Dark Dimension, to disarming the lock-out mechanism for Alpha's activated self-destruct, and many other achievements. Though Billy did manage to attract girls earlier in his "nerd-like" persona, it was after he began his journey toward self-improvement that he would garner more attention from romantic interests, even more so than the other members of the team.

Billy was accepted into the Young Scientists of America program. He befriended Zack's cousin Curtis when he became the newest student at Angel Grove High. Curtis' musical interests, particularly in playing the trumpet, sparked Billy's intrigue into the rhythmic patterns of jazz music.

Zedd's Invasion
When Lord Zedd invaded Earth after doing away with Rita, Zordon upgraded the Dinozords into the Thunderzords; Billy was given control of the Unicorn Thunderzord. When Zordon and Alpha disappeared, Billy was the one to find the secret door where they were making the White Ranger. While most of the other Rangers were disappointed of a new member was suddenly joining them, Billy knew that they needed a new Ranger to help them against Zedd, regardless of who it was. However, he was happy to find that the White Ranger turned out to be former teammate Tommy Oliver.

New Friends and Teammates
One day, while roller blading in the park with Tommy and Kimberly, Billy unexpectedly met Rocky DeSantos, Aisha Campbell, and Adam Park, and helped them stop a runaway stroller carrying a teacher's baby boy. When Zedd kidnapped the new teens to change them into his own Dark Warriors, Billy, Tommy, and Kimberly set out to rescue them. Billy entered the cave where the teens were being held and grabbed the evil snake that would turn them evil. However, the snake wrapped itself around Billy's neck, and he was forced to remove his helmet to breathe, thus revealing his identity. Rocky, Aisha, and Adam swore to keeping the Rangers' secret and became friends with everyone. When Jason, Trini, and Zack were chosen to attend a peace conference in Switzerland, Billy and the Rangers had to retrieve the Sword of Light to allow the Rangers to transfer their powers. Though Billy was sad to see his teammates leave, he was happily surprised that his new friends would take their place as the new Rangers.

When Kimberly fell through a time wrap to the days of the Wild West, she would recruit Billy's ancestor William in the 1880s to become the first Blue Ranger when she assembles and takes command of the Wild West Ranger team in a battle against Goldar and several other time traveling foes.

Ninja Quest
After the Thunderzords were destroyed by Rito Revolto, Billy and the other Rangers sought out Ninjor, the creator of the Power Coins, to give them new powers. Billy became the Blue Ninja Ranger and controlled the Wolf Ninjazord. It was Billy who was able to use his intelligence to let the Rangers control the Shogunzords and he would personally control the Blue Shogunzord.

Mighty Morphin Alien Rangers
The Rangers were de-aged by a time reversal spell performed by Rita Repulsa's father, Master Vile. Billy devised a plan to restore the Rangers' proper age using a machine that ran off of the Power Coins. Billy restored himself, but Goldar stole the machine, and Zedd and Rita destroyed all six Coins.

With his Wolf Ninja Coin destroyed and his Triceratops Power Coin damaged beyond use, Billy's role changed. He no longer fought as a Power Ranger, but rather acted solely in an advisory and supporting role, acting in this period as a liaison between the Alien Rangers and Earth.

Zeo
Billy officially retired from active Ranger service, allowing Tanya Sloan (who was sent back in Aisha Campbell's place) to take his place while he continued his support role by creating and maintaining most of the weaponry, gadgets and Zords the Zeo Rangers would use. He traveled briefly to Aquitar to assist the Aquitian Rangers in battling with a race of aliens called the Hydro Contaminators. To do so, he completed a prototype device that Cestro started to defeat them. Upon his return, his ship was diverted by King Mondo to fly straight into the sun. From the Power Chamber, Zordon, Alpha 5, and the Rangers were able to rescue him.

Before the Gold Ranger's identity was revealed as Trey of Triforia, several red herrings mislead the viewers into believing that the Gold Ranger was Billy, but when Rocky confronted him with this theory he assured the team that he'd never have kept such a thing secret from them, and had simply been busy working on a never-specified project (most likely the Turbo powers). When Trey returned to Triforia on sabbatical to try to unify his three selves, Billy was selected to assume Gold Ranger's powers. However, the "negative proton energy" that his body had absorbed in the Command Center's explosion prevented him from taking the powers. Instead Jason, the former Red Ranger (who, being nowhere near the Command Center at the time of its explosion, was a safe choice), received the powers.

Billy was last seen to be suffering from accelerated aging because the regenerator he used to restore his proper age had a side effect. To counter this, he traveled to Aquitar for a cure from their Eternal Falls (analogous to the Fountain of Youth), and opted to remain there with Cestria, a female Aquitian with whom he had fallen in love.

Ranger Key
The Blue Mighty Morphin Ranger Key is Billy's personal ranger key. This key along with the majority of the Core Ranger Keys are seen lining the Command Center's interior walls. This key is mainly used by Noah Carver (Super Megaforce Blue) who uses it to fight as the Blue Mighty Morphin Ranger.

MMPR fan club video

 * Being interviewed, Billy sat in his lab; he had light brown hair and wore a blue shirt and his thin-framed glasses, using absolutely no technospeak, and furthermore using the occasional bit of incorrect grammar; whether he wore a communicator is unknown.
 * As a child, Billy had started reading very early and had read the newspaper with his dad; then when he went to school, he became interested in science and the world.
 * Recalling a frightening experience, Billy described fighting Madame Woe to save Marge, his girlfriend at the time; he said it had been hard and scary, but he'd done it.
 * Billy gave his favorite food as guacamole cheeseburgers, adding that he liked a lot of fast food, such as pizza, French fries, and hamburgers.
