"Gokai Blue!"

Joe Gibken is the second-in-command of the Kaizoku Sentai Gokaiger.



Zangyack Agent Gibken

Joe serving Zangyack.

Joe was once a member of the Zangyack's Imperial Special Forces. While training under the Zangyack, Joe was often forced to endure rigorous and abusive training. It was during this time that he also trained under Sid Bamick, his sempai, or mentor. Sid taught Joe many of the sword-fighting skills he used to great effect as Gokai Blue.

When ordered to execute a group of captive children, he blatantly refused and attacked his superior officers, letting the children run away. Because of his insurrection, Joe was taken prisoner and outfitted with an electric collar that could keep track of his every move and would emit an electric shock that could kill him, should he try to remove it. He managed to escape though, with the help of Sid. Unfortunately, his sempai was left behind.

Once on the outside, he continued to fight through hordes of Gormin and Sugormin that came after him with a Z=1,000,000 bounty on his head, unable to settle anywhere in one place due to the tracking collar on him. It was then that Captain Marvelous first noticed Joe. Slowly becoming overwhelmed by his attackers, Joe wasn’t about to give up, though his end was just about imminent. Then [Marvelous appeared, offering to help him fight the Gormin and Sugormin off. Realizing that Marvelous was a space pirate, Joe warned him that he would get no money for saving him… and that was when Marvelous told him that it wasn’t money he wanted. He wanted Joe.

They fought off the Zangyack forces together, proving to be quite the combination. Afterwards, Joe told Marvelous about the collar around his neck, and how removing it could kill both of them. Still, Marvelous took it upon himself to pry it off of Joe with his bare hands. As they faell to the ground, Marvelous mades his intentions known to Joe (that he was searching for the Greatest Treasure in the Universe), and he accepts, thankful for what Marvelous had done for him, and vowing to stay with him until he reacheed his dream. Marvelous passed him a Mobirate and the Gokai Blue Ranger Key. Ep. 11: The Serious Rebellion Ep. 12: The Guaranteed Showy Samurai


Three new comrades

Joe was the first member of Marvelous’ crew. Some time after, the crew received three more members. The first was the female thief, Luka Millfy/Gokai Yellow. Ep. 34: Dream Comes True They then came across Don Dogoier/Gokai Green, an insignificant but intelligent mechanic who Luka asked to fix their ship's computer, he was scared at first because of their reputation but returned and did his deed, saying that he needed to fulfill his promise. The others were impressed at how he fixed their computer, and also cleaned up the Galleon and served them dinner. Marvelous decided to recruit Don into their team, with Joe wishing Don good luck in an uncharacteristically friendly manner.Ep. 42: The Strongest Man in the Universe Don's dual-gun skills impressed Joe Ep. 43: To the Legendary Hero Later, they met their fifth man, figuratively speaking. Ahim de Famille, princess of the destroyed planet Famille. Ahim wished to give hope to the other survivors of Famille and other destroyed worlds. She had trouble with becoming a pirate at first and interacting with the Gokaigers, while training with a sword under Joe's watch, she found it so heavy she fell to the ground, causing Joe to give his signature forehead-grip. Ep. 41: Something I Don't Want to Lose

Finding out that Earth was where the greatest treasure in the universe could be found, they set a course for the planet. Unfortunately for them, the Zangyack had their eye on the planet as well, planning on capturing it. At first the Gokaigers were uninterested in fighting off the Zangyack for the sake of the Earth—they were more concerned with finding the greatest treasure. This all changed when they saved a group of children. From then on, they became an official enemy of the Zangyack, with bounties placed on their heads (as of now, Joe has a bounty of 8,000,000 Zagins).

What are friends for?

After the team realized they could not take a short cut in mastering the Ranger Keys' powers, Marvelous sent Joe and Ahim to pick up some food. However, the two stop in response to the Action Commander Zodomas, whose swordsmanship attracts Joe's attention and fights him as the Gokaigers battle the Gormin. However, the Action Commander overpowers Gokai Blue and takes his leave as the other Gokaigers arrive. While the others eat, Joe proceeds to hone his fighting style to counter Zodomas's fighting style with Ahim forced to watch before Joe tells her. As Luka tells Ahim to accept his reasons out of friendship, Joe completes his training. The next day, Joe finds Ahim waiting for him and as she gives him her Gokai Saber to use in his upcoming duel with Zodomas. However, Zodomas uses Zugormin to as Gokai Pink arrives to his aid before the other Gokaigers arrive. After the others assume the forms of the Gekirangers and Dekarangers to take out the Zugormin, they give their Gokai Sabers so Gokai Blue he can use a five-blade fighting style to defeat with his Five-Blade Style Blue Slash. When Zodomas and the Zugormin are enlarged, the Gokaigers form Magi Gokaioh to ground Zodomas before destroying him. Soon after, Joe presents a "thank you" cake to the crew and is modest about it. What Are Friends For?


While searching for a Samurai as per Navi's latest hint, the team came across Princess Kaoru Shiba, who had once held ShinkenRed’s power. Discovering that the ones who held the Shinkenger keys were pirates, she demanded that they give the keys to her. Of course, they refused. This resulted in Joe challenging her to a duel—if she wins, she gets the keys. If he wins, she shares the Shinkengers’ Greater Power.

Unfortunately, the duel is cut short, interrupted by an invasion by the Zangyack. Warz Gil, the Zangyack Emperor's son and commander, decides to come down to Earth to get the job done himself with the help of Barizorg and Deratsueigar. While the Gokaigers are engaged in combat with Delzeiger, Joe goes off on his own to confront the Emperor's son. Unfortunately for him, Barizorg is there to protect him, and as they fight it is revealed through a specific special attack that Barizorg uses that he is actually Joe's old sempai, Sid.

Clearly distraught by this, Joe was so shocked, he left himself open to an attack, Marvelous steps in and takes the brunt of the attack, saving him and also dealing Warz Gil a wound from his pistol. Barizorg escorted Warz Gil back to their ship, retreating—making it possible for Joe and Marvelous to retreat back to their ship as well.

Seeing his comrade in pain, and still curious over the fate of his old sempai, Joe decides to take matters into his own hands and goes out on his own to try to get through to Sid/Barizorg. Though determined to restore his sempai's memories, he is unsuccessful. Feeling as though he ended up in the same place he started, Joe suddenly realizes that he already has comrades that he left behind... and he can't let that happen.

As he makes his way back to them, he bumps into Kaoru again and she explains to him that she has seen the bond between the group, and that she has lost the duel. As promised, she gives them the Shinkengers' Greater Power. Joe rejoins his comrades and they defeat Deratsueigar. Afterwards, Joe makes an off-handed comment that he is "home," meaning Marvelous and the rest of the crew. Ep. 11: The Serious Rebellion Ep. 12: The Guaranteed Showy Samurai

Pirates vs. Angels

While the Gokaigers fight off a steady stream of Gormin, and Sugormin, their predecessors, the Goseigers, show up and steal their ranger keys back before the Gokaigers can use them to transform. At first, the two teams butt heads—the Goseigers upset over the Gokaigers having possession of their powers (more specifically, GoseiKnight’s power, after they get their own back), and the Gokaigers upset over the Goseiger’s sneaky attempts to steal their powers back.

Their conflict was interupted by the return of the Black Cross King, who revived three enemies of the Super Sentai to fight the two teams in a seperate dimension each. Joe and Luka, with Aguri/Gosei Black]] and Moune/Gosei Yellow took on Gaiark Crime Minister Yogoshimacritein his Ugatz in a Feudal Japan movie set within a thirty minute timeline. Eventually, the two teams put their differences aside, find that they have more in common, and join forces (along with the spirits of the other past Sentai) to stop the Black Cross King.

The Black Cross King, having stolen the Ranger Key chest, made them into his puppet army. After discovering that when defeated they would be turned back into Ranger Keys, the Gokaigers and Goseigers engaged the past 33 Sentai. After single-handedly taking down the copies of the Gingamen, Joe teamed up with Hyde/Gosei Blue against a group of several Blue Rangers.

After defeating the Black Cross King, the Goseigers relinquish their keys back to the Gokaigers, as well as their Grand Power. The Gokaigers also received the Grand Powers of Gorangers, JAKQ, Denjiman, Goggle V, Dynaman, Bioman, Turboranger, Dairanger, Boukenger, and Go-Onger. Gokaiger Goseiger Super Sentai 199 Hero Great Battle

The Sixth Gokaiger

Shortly after their encounter with the Goseigers, the Gokaigers met Gai Ikari, who would be the sixth member of their team, GokaiSilver. With his knowledge of all the previous Sentai teams, being quite the fanboy, the Gokaigers are able to decipher Navi’s predictions more clearly, as to where to find the Greater Powers. Ep. 17: The Amazing Silver-Colored Man Ep. 18: The Big Abare with the Dinosaur Robot Drill


Joe, along with Marvelous, Luka, and Ahim, were deboned by the Action Commander Worian. They were brought back to normal when Worian was destroyed after Don inspired Gai to combine the 15 Sixth Warrior keys to create Gold Mode. Ep. 19: Armor of the 15 Warriors

An act of mercy

When Navi told the Gokaigers they would have to offer help in order to find their next greater power, Joe joined with Don in looking for a good deed to do, resulting in them having to deal with a transvestite after they give back a ring that he dropped on the sidewalk. It was Luka and Ahim who discovered the latest former Sentai hero, which resulted in the Gokaigers gaining the greater power of GoGo-V. That is, after the foiled Basco's attempt to get it. Ep. 23: People's Lives are the Future of the Earth

Skateboarding lion

Joe’s past comes back to haunt him once again when one of Navi’s predictions prompts them to find “a skateboarding lion,” which Gai concludes is Yellow Lion of Liveman. As Joe and Ahim pair up to look for him, Joe saves an infant in a stroller that is rolling down a set of stairs—but he isn’t the only one there to stop the stroller. Jou Ohara, Yellow Lion, is there to help as well. Not long after meeting him, they encounter some Gormin and Zaien, the Zangyack scientist who turned Sid into Barizorg, they find out, intends to kidnap various talented fighters to turn them into mass-produced Barizorg. With this information, Joe asks Jou if there is a way to reverse the process, but finds out there isn’t.

After lamenting over this, Joe resolves that the only way to save Sid’s soul is to defeat Barizorg. He stands with his comrades to defeat Zaien, so that they could stop him from subjecting the people he kidnapped to Sid’s fate. Ep. 30: Just a Lone Friend's Soul

Showdown with Barizorg

It was when the Gokaigers finally do battle with Warz Gill himself, that Joe made his final stand against Barizorg. When GokaiOh is crippled in battle against Warz's new weapon, the Great Warz, Marvelous forcibly ejects his crew from the control center. Angered over this, Joe makes his way back to where the Galleon fell, and encounters Barizorg on the way, where they battle. Ep. 37: The Strongest Fighting Machine

Although getting knocked back by Barizorg a few times, Joe realizes that his relationship to Marvelous is different from that of Barizorg to Warz Gil. Where Barizorg blindly fights for his “boss,” who will not protect him, Marvelous will continue to fight for his comrades, even if they fall. Joe cannot die because he has a debt to fulfill to Marvelous—and he intends to keep his promise. Successfully blocking Barizorg’s signature attack, Joe, as GokaiBlue, performs the same attack and sends it back toward the cyborg, effectively destroying it. Upon its destruction, Sid’s spirit appears to Joe and tells him this is strength is not his alone—to use it to help his comrades. With that, Joe regroups with Luka, Ahim, Doc, and Gai to find Marvelous and finally defeat Warz Gil. Ep. 38: The Power to Seize Dreams

Super Hero Taisen

When Marvelous takes control of Dai-Zangyack and leads them in battle against Kamen Riders, Joe wonders why they have to fight the Riders and, with Don, joins with Daiki Kaito (Kamen Rider Diend), who is looking for Marvelous' treasure, and Hina Izumi, a friend of Eiji Hino (Kamen Rider OOO), in finding out. They eventually meet the crew of the time-travelling DenLiner. Kamen Rider × Super Sentai: Super Hero Taisen

Gokai Blue


Gokaiger costume

In battle he duel-wields the Gokai Sabres. Often he positions himself in-between enemies so he can battle both at once. He likes to fight with one arm behind his back occasionally.

Gokai Blue Gold Mode

Gokai Blue Gold Mode as seen on a Dice-O card.

As shown in cards, Gokai Blue, along with the other Gokaigers, can use Gai's Gold Anchor Key to become Gokai Blue Gold Mode. However, as it is Gai's key, Gokai Blue's Gold Mode is identical to Gokai Silver's Gold Mode, with the 15 Sixth Rangers rather than the past 34 Blue Rangers.


For attacks, Gokai Blue's been seen to somehow summon manifestations of past rangers. He is the first ever seen doing so.

Ranger Key

Gokai Blue Ranger Key

The Gokai Blue Ranger Key.

The Gokai Blue Ranger Key (ゴーカイブルーレンジャーキー Gōkai Burū Renjā Kī?) is Joe's personal Ranger Key which allows him to transform into Gokai Blue. Whereas the keys of the 34 Sentai were created out of the sacrifice of their powers in the Great Legend War, the origin of the Gokaiger Ranger Keys is unknown, though it can be assumed AkaRed had a role in their creation.

As with the other Gokaiger Ranger Keys, this key is commonly used in the Gokaigers' Ranger Key-compatible arsenal and mecha for different functions and attacks.

This Ranger Key was turned into a Ranger puppet once, by Basco. Along with the other Gokaigers bar an incapacitated Marvelous, Joe confronted and defeated the puppet Gokai Blue.


A calm man, whose words are few. A compliment from this man is rare, a man with a serious personality who is hard on himself. Always training up his abilities with weapons, and never misses. Has known Marvelous the longest, and as such, he understands Marvelous the best out of the entire crew.


After escaping from Zangyack, his bounty was Z=1,000,000, then doubled after the Gokaigers hinder Zangyack's efforts on Earth. Ep. 5: Judgement Pirates This is then raised even further to Z=4,000,000. and yet further to 8,000,000. Ep. 39: Why? We're High School Students

Behind the scenes


Joe Gibken is portrayed by Yuki Yamada (山田 裕貴 Yamada Yuki?). Prior to the series, he stated the series he wanted to become the most were the Kakuranger.

As Gokai Blue, his suit actor is Yoshifumi Oshikawa (押川 善文 Oshikawa Yoshifumi?), whose previous role was Gosei Black in Tensou Sentai Goseiger and later served as suit actor for Red Buster in Tokumei Sentai Go-Busters.


  • Joe shares a few things in common with 4 out of 5 of the other Gokaigers in terms of counterparts:
    • He is one of three Gokaigers to have a counterpart from all 34 past Super Sentai teams, the other two being Marvelous and Luka.
    • He is one of two Gokaigers to have all of their counterparts share the same color as them, the other being Marvelous.
    • He is one of two Gokaigers with no counterpart that was either an official or technical leader of their team, the other being Gai.
    • He and Ahim share the same amount of opposite gender counterparts (4).
  • Ironically, even though Joe is calm and serious, most of his male counterparts (DenziBlue, GoggleBlue, DynaBlue, Blue Three, Change Pegasus, Blue Flash, Blue Mask, Blue Turbo, TriceraRanger, TenmaRanger, NinjaBlue, OhBlue, Blue Racer, GingaBlue, GaoBlue, Bouken Blue, and Go-On Blue) were much more lighthearted and/or childish.
    • His serious counterparts include Aorenger, Dia Jack, Battle France, VulShark, FiveBlue, MegaBlue, GoBlue, TimeBlue, AbareBlue, DekaBlue, GekiBlue, Shinken Blue, and Gosei Blue.
  • 4 of Joe's counterparts (Blue Dolphin, Blue Swallow, HurricaneBlue, and MagiBlue) were originally female.
  • 2 Blue Rangers (Signalman and KuwagaRaiger) are not Joe's counterparts, as these Blues aren't part of their respective teams' cores.
  • Joe is the only male Gokaiger who has transformed into more then one female Ranger.
  • Joe's proficiency in swordplay could stem from his surname: "Ken" (剣) is the commonly used word for "sword" within the Super Sentai Series.
  • Joe's attitude, past and use of dual swords is similar to Kevin Levin, from Ben 10: Ultimate Alien.
  • Even though Joe is the second-in-command of the Gokaigers, only 8 of his counterparts (Aorenger, Battle France, FiveBlue, GoBlue, TimeBlue, DekaBlue, GekiBlue, and Shinken Blue) were the second-in-command of their teams.
