"It's time for mollecular transmutation! Triceratops!"
―One of Billy's roll calls.[src]

"Jason! That blow didn't even faze him!"
―Billy's most infamous line after the Megazord punched Goldar down in spite of the line not syncing up with the action.[src]

"We can't back off! Just because we're in a little trouble, we've gotta keep trying!"
―Billy after Zack suggested backing down whilst the Megazord was taking a beating from the Grumble Bee's sonic attacks.[src]

Billy Cranston is the Blue Ranger of the Mighty Morphin Power Rangers.

Retroactively, he is also referred to as the Mighty Morphin Blue Ranger or Blue Mighty Morphin Ranger, though these are terms of address referencing the show as opposed to proper labels.

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).

Billy Cranston was also adapted for the Papercutz comics in 2014, which function as lost episodes of the original TV show[1][2], in which he took on two new helmet formats, and the alternative canon BOOM! Studios comics, assuming the (temporary) forms Black Ranger and Green Ranger, and a prototype of combat Exosuit Blue Ranger.

Early Life

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. Comicicon.png COMIC STORY- [[|]]

Becoming a Ranger


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

Billy began the series as the stereotypical "nerd," speaking almost exclusively in technobabble throughout Season 1. 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, and 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 person was Willy, a young boy who 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 remote access to the Command Center's teleportation unit. When they are not saving the world, teenagers with attitudes chosen by Zordon gather at the Angel Grove Youth Center. Trini updates Alpha 5 with the language of the year 1993. Far away, Dr. Carver and Dr. Kenyon discover a new civilization and the largest statue ever built in ancient America. Unintentionally, Dr. Carver activates the terrible cross between monster and robot that attacks the excavation site. Back at the Youth Center, Billy creates a device with internet access when everyone sees the attack on TV. In the territory of the attack, summoning the Dinozords, the Power Rangers fight against a terrible monster. Struck by the lightning of the stone giant, the Rangers lose communication with Zordon and have their pieces exchanged makes it difficult in battle. With the help of Alpha 5, the exchange effect was reversed and the Rangers, winning the battle and returning the giant to its location.Comicicon.png COMIC STORY- Rita Repulsa's Attitude Adjustment

Zordon chose Billy to become the Blue Ranger.

It was revealed that Billy was bitten by a fish in his youth during an experiment involving whirlpools, causing him to develop icthyophobia: fear of fish. This fear would persist well into his teens and Rita would use a spell to exacerbate this fear. When he was the last remaining Ranger able to contend with the Goo Fish monster, Billy overcame the spell, freeing his friends and helping tob defeat the monster. He later completely overcame the fear while 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 transform 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 and his friends in the form of Power Rangers defeat Korruptor using Dino Megazord.Comicicon.png COMIC STORY- Going Green

Billy facing his ichthyophobia.

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. As a Ranger, he had a wide array of accomplishments, including creating the method by which the Ranger's would initially infiltrate Rita's Dark Dimension to disarming the lock-out mechanism for Alpha's activated self-destruct. 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, to the point of getting more 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 his interest in and skill at playing the trumpet, sparked Billy's intrigue in the rhythmic patterns of jazz music.

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. Comicicon.png COMIC STORY- [[|]]

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. Comicicon.png COMIC STORY- [[|]]

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. Comicicon.png COMIC STORY- [[|]]

After the Black Dragon arc, Billy becomes committed to being more athletic and becomes a bit more muscular in physique. While things seem to be normal in his life, his parents are in an overprotective state given he and Tommy had to stage a ruse to explain their long absence by teleporting under some debris for rescue workers to find them. So from the perspective of Billy's mother, her son was buried alive for several days and this created the very real adult fear she could have lost her child. Billy is a little annoyed by his mom's paranoia, but Trini tries to tell him to consider her feelings.  He does try to be understanding but hopes for things to be a little more normal in the future. Comicicon.png COMIC STORY- [[|]]

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 in a new member 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. The Rangers are driving out to the desert in Billy's RADBUG so they can send Rita back into space without any civilians seeing. During the drive, Zack reveals that he has gotten a gift for his girlfriend Angela: a pair of walkie-talkies designed after characters from an old children's show she likes. Trini explains to Kimberly that people often like to collect things that remind them of what made them happy, though Kimberly can't quite understand it. As the Rangers get out of the Radbug for a breather, Zack puts the walkie-talkies in the car's trunk next to Rita's Dumpster. Up in the Moon Palace, Lord Zedd is still in disbelief that his Scarlet Sentinel has fallen. Seeing the Rangers in the desert, he gets an idea and uses his power on the Radbug. Suddenly, the car comes to life and begins attempting to ram into the Rangers while claiming that it will no longer stand for being treated like a slave. The Rangers morph and use their Power Weapons to create a ramp that flips the Radbug on its roof and immobilizes it. Zedd throws a grenade down and the Radbug grows in size, plus gains a face made from Zack's walkie-talkies (which also gives Rita a means to complain about all the hassle she's getting put through). Tommy summons the White Tigerzord to deal with the Radbug while the other Rangers form the Thunder Megazord, and he tries to stop it by climbing into the runaway vehicle and driving it with his Tigerzord at the wheel. This only serves to anger the Radbug as it turns into a bipedal monster and ejects its Zord-driving driver. The Thunder Megazord rides the White Tigerzord to catch up to the Radbug as it nears Angel Grove's city limits. Once it gets close, the Megazord jumps onto the Radbug's hood and tears its fuel line out to end the joyride.With the Radbug back to normal, Billy tends to repairs while the other Rangers prepare to send Rita on her trip. Zack also recovers his walkie-talkies, which are perfectly intact, and Kimberly admits that she'll never doubt the value of collectibles again. Comicicon.png COMIC STORY- By Bug... Betrayed

New Friends and Teammates

One day, while rollerblading 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, intending 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 ensure he could breathe, thus revealing his identity to Rocky, Aisha, and Adam. The trio swore to keep 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 Jason, Trini, and Zack leave, he was happily surprised that Rocky, Aisha, and Adam would take their respective places as new Rangers.

When Kimberly fell through a time warp 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 Rangers team in a battle against Goldar and several other time-traveling foes.

Ninja Quest

"It's Morphin Time! Blue Ranger Power!"
―roll call as the Mighty Morphin Blue Ranger[src]

Billy receives his Ninja Powers.

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 Blue Wolf Ninjazord. Billy used his intelligence to enable the other Rangers to control the Shogunzords and would personally control the Blue Shogunzord.

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 ages 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.

Billy and the Alien Rangers.

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, and did not join the remaining active Rangers in their search for the Zeo Crystals and acted solely in an advisory and supporting role, serving as a liaison between the Alien Rangers during this period.


Billy officially retired from active Ranger service, allowing Tanya Sloan (who was sent back in Aisha Campbell's place) to take his place as an active Ranger in the field. He continued in the support role he had adopted during the Aquitian Rangers' time on Earth, assisting Zordon Alpha 5 with tasks in the Power Chamber and 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.

Billy gives his Zeo Subcrystal to Tanya.

Before Trey of Triforia was revealed to be the identity of the Gold Ranger, several red herrings mislead the viewers into believing that the Gold Ranger was Billy. When Rocky confronted him with this theory, he assured the team that he would never have kept such a secret from them, and had simply been busy working on a never-specified project (most likely the development of 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.

Super Megaforce

The five Mighty Morphin Power Rangers join the battle.

Billy and the other Mighty Morphin Power Rangers returned as part of the army of Legendary Rangers led by Tommy that helped the Mega Rangers defeat the Armada once and for all, fighting in a huge battle against hundreds of X Borgs and dozens of Bruisers. It is not explained how he returned to Earth from Aquitar, possibly by the same teleportation that the Aquitians used. He returned to Aquitar after the battle. It is unconfirmed how he reclaimed his old Blue Ranger powers. Tvicon.png TV STORY-Legendary Battle

Beast Morphers

The other four Mighty Morphin Power Rangers come to help.

Billy responded to Jason's signal and returned alongside his fellow Mighty Morphin Power Rangers as part of the Legendary Dino Rangers army. When Evox summoned his massive Chimerazord, his team joined in summoning the Megazord and aiding in its defeat. With Evox on the run again, the teams departed. Billy went back into his own dimension and, even though it's not officially stated, he probably returned to Aquitar. Tvicon.png TV STORY-Grid Connection

Exosuit prototype

Billy experimented and developed a new prototype Ranger combat suit design with the help of Alpha 1 and operated it in Command Center simulations for tests. This Ranger suit is fully armor-plated and is equipped with strength enhancements greater than that of his normal Ranger suit, short-range jet propulsion for flight, and deployable wrist-mounted Horn Chain weapons based in design on similar ones equipped on his respective Zord.

Despite its impressive features, Zordon forbids its use in the field because of technical glitches such as a critical failure of the jet propulsion systems and a need to put the safety of his Rangers above all else. The suit was later critically damaged after Alpha 5 used it to distract Alpha 1 long enough for the Megazord in Tank Mode to fire on the evil robot, the damage rendering the suit unusable until it can be repaired.

Behind The Scenes



  • Billy's departure remains the most controversial exit in the show's history. Yost last played Billy in the episode "King for a Day" before leaving under suspicious circumstances with an unknown actor playing him in "Rangers of Two Worlds" and an uncredited voice actor doing his voice during his goodbye message. According to Saban themselves, Yost left due to disputes over their contract and pay similarly to the events surrounding "The Power Transfer." However, the more commonly accepted explanation is that Yost left as a result of homophobic remarks allegedly made by the behind-the-scenes crew (Yost being openly gay), with the explanation from Saban being thought of as sugar coating.

Concept Art

Billy Cranston/Mighty Morphin Blue Ranger Go Go Power Rangers Concept art

  • Billy Cranston/Mighty Morphin Blue Ranger's concept was designed by Eleonora Carlini


  • Billy is the only original Power Ranger to remain for the entire MMPR series.
  • Billy received a tribute in the credits of Rangers of Two Worlds part II.
  • Billy is the only Ranger to keep a single power for three seasons without giving it away or switching colors, and the only original Ranger to not be replaced, as he stepped down from his position at the start of Zeo.
  • Billy is the only Ranger to retire from being a Ranger, but not immediately leave the show.
  • Because of the absence of Yost, stock footage of Billy was used for his departure and his character was voiced by someone else. He was also the last of the original Power Ranger team to leave the show. Also of note is that backstage, David Yost left the show on bad terms, causing the writers to change the Turbo movie's plot so that the Rangers created the Turbo powers themselves with Alpha 5's assistance rather than by Billy himself.
  • David Yost's departure from Power Rangers occurred as a result of drama behind the scenes. Yost, at the time struggling with his homosexuality, was frequently harassed and insulted by the show staff. Unable to reconcile, Yost left the show and was written off without involvement in filming the episodes that would remove Billy for good.
  • According to IMDb, Walter Jones was originally cast as Billy. However, when he auditioned, he said he thought he would be more recognizable as the Black Ranger, so he was re-cast.

Billy as a punk in Power Rangers Punks

  • Billy frequently dressed in clothing that was oversized or otherwise baggy or frumpy, in an effort to cover David Yost's well-defined physique due to him being a gymnast (as he was supposed to be a nerd, and thus not entirely athletic). This effort was gradually dropped by the second season of MMPR.
  • During the 2010 reboot of Mighty Morphin' Power Rangers, a toy version of Billy was seen with the Dragon Shield, though Billy never wore Tommy's Dragon Shield in the show.
  • It is said that actor Bryan Cranston was the inspiration for Billy's last name.[4] However, the name was already used in the Bioman pilot.
  • Judd Lynn had originally intended for Billy to be the true identity of the Phantom Ranger, however, this plot was eventually dropped.
  • In the Bio-Man pilot, his name was shared with the counterpart to Blue3, and rather than super-intelligent, he was a "heartthrob with a body of steel".
  • Billy is a playable character in Power Rangers Legacy Wars.
  • Despite rumors that Billy was originally meant to be the Gold Ranger, David Yost has since confirmed that there were no plans for this.[5]
