As the one who had helped Joker implement the JAKQ project; Sokichi himself is considered the ultimate “super cyborg” as his bionic implants allowed him to harness and manipulate all four cosmic powers wielded by the four core members. Ep. 23: White Birdman! Big One

Gaoranger vs. Super Sentai

Twenty-four years after the fall of Crime, Banba returned in Hyakujuu Sentai Gaoranger vs. Super Sentai as the leader of the "Dream Sentai" team. Using his skills as a master of disguise, he appears as a mysterious old man who helps the Gaoranger learn from the other Sentai heroes of the past. He usually does not shout a 'henshin' phrase, but did shout "Big One!" in Gaoranger vs. Super Sentai. He also used an attack called "Big One Finish", which is a spectrum slash with the Big Baton. Although his teammate Goro Sakurai appeared with the other Reds, the two did not interact.


Legend War

Years later, Banba became co-leader alongside Akarenger in leading not only his team, but every single Sentai ranger in existence, against the Empire of Zangyack when it attacked the Earth in the Great Legend War. Both he and Tsuyoshi appeared to the Goseigers when they became overwhelmed by Gormin to regroup them with all other Sentai heroes for the final assault.

After fighting against hundreds of Gormin and their Zgormin commanders. Tsuyoshi Kaijo aka Akarenger noticed the fleet moving towards them, he gathered all the Rangers together and gave them the order to sacrifice their powers to wipe out the first invasion's armada. The powers of Big One are later used by Luka Millfy via the Ranger Keys. Ep. 1: The Space Pirates Appear Gokaiger Goseiger Super Sentai 199 Hero Great Battle

Black Cross King

In Gokaiger Goseiger Super Sentai 199 Hero Great Battle, the 35th anniversary movie, Big One is seen leading the Great Legend Army alongside his predecessor Akarenger. Sometime during the Black Cross King's return, through the Ranger Keys, he thanks the Goseigers and the Gokaigers, and informs them even though they are not Earthlings, their hearts that love and protect others are the same as the other Super Sentai.

Farewell Space Pirates

After the Gokaigers defeated the second Zangyack invasion, Marvelous returned the Ranger keys to the Super Sentai, so it is assumed Sokichi and his team have their powers back. Final Ep.: Farewell Space Pirates

Super Hero Taisen

Dimensional wall - Sun Vulcan, Battle Fever, JAKQ, Denziman

J.A.K.Q., alongside Sun Vulcan, Battle Fever, and the Denzimen, emerge through a dimensional wall.

Sokichi, alongside his team, among the majority of the Super Sentai heroes, was caught up in the "Super Hero Taisen" incident which eventually resulted in the Super Sentai teams and Kamen Riders joining forces to defeat both Dai-Zangyack and Dai-Shocker. During the final battle, he is seen fighting Long and Panthera Lutes. Kamen Rider × Super Sentai: Super Hero Taisen

Big One appeared with his team among the first 38 Super Sentai whom collectively empowered Wild Tousai Shuriken King in its fight against the titanic Gillmarda, granting the Ninningers and Zyuohgers the power to perform the Zyuoh Ninnin Super Sentai Burst which destroyed Gillmarda with the combined power of all 40 Super Sentai.

Super Sentai Strongest Battle

Sokichi joined the Super Sentai Strongest Battle as a member of Curveball Team, but didn’t get to participate in the competition because his team was eliminated after losing the first round against Super Strong Team.


Sokichi is a flamboyant playboy and master of disguise. He is a cool-headed leader and masterful tactician who can come up with the most brilliant of battle plans to defeat Crime's cyborgs.

Big One


Big One Suit

Dubbed “The White Superman” (白い超人 Shiroi Chojin), as Big One, Sokichi's enhancements enable him to manipulate all four energies (atomic, electrical, gravitational, and magnetic) allowing him to perform a variety of incredible feats including flying, superhuman strength and super speed. Furthermore, unlike the core members, Sokichi is able to transform without the use of the Strengthening Capsules; instead taking a sniff out of a magical red rose.

In battle, he wields a fighting baton called the “Big Baton” which he can use to strike and hit opponents with great force and impact. As seen in Gaoranger vs. Super Sentai, Big One can use the Big Baton to perform an attack called the Big One Finish.



Big One's suit is completely white cloth with white gloves and boots. Around his chest as well as the cuffs of his boots and gloves is a V-like formation similar to a rainbow of four colors (from left: green, blue, red, yellow) flowing from a point and flying upwards to the top of his shoulders. His belt is likewise white with no holsters but has a huge letter "B" surrounding the middle. His cape is much longer than the other J.A.K.Q., going down to his ankles and red in color. The rainbow "V" appears likewise taking up a helmet that is mostly white with a huge number "1" around the forehead.

Ranger Key

Big One Ranger Key

The Big One Ranger Key.

The Big One Ranger Key (ビッグワンレンジャーキー Biggu Wan Renjā Kī) is Sokichi Banba's personal Ranger Key and what became of his powers after he along with the rest of the 34 Super Sentai sacrificed their powers to end the Great Legend War.

This key along with the majority of the Ranger Keys were collected by the Red Pirates and later used by the Gokaigers. The Big One Ranger Key was mainly used by Luka Millfy (Gokai Yellow), who used it to fight as Big One. It was also used by Joe Gibken (Gokai Blue) and Captain Marvelous (Gokai Red) on one occasion each.

The J.A.K.Q. keys, along with all the Ranger Keys of the first 33 Super Sentai, were briefly taken by the Black Cross King and turned into Ranger puppets that were fought by the Gokaigers and the Goseigers. The J.A.K.Q. keys were defeated by Super Gosei Red. Gokaiger Goseiger Super Sentai 199 Hero Great Battle

After Zangyack were finally defeated, the Gokaigers gave the Ranger Keys back to their rightful owners. Sokichi received his key and became Big One once more. Final Ep.: Farewell Space Pirates


Behind the scenes


Big One is featured as #57 in the 1986 archive compilation video Toei 100 Great Heroes Super FightIcon-crosswiki.


  • Sokichi's given name is a stealth pun because "ichi" is Japanese for one.
    • He is the first Sentai Ranger with a number designation; three teams have done so since (Biomen, ToQgers, and Patrangers).
  • Hiroshi Miyauchi, who played Banba, previously played Akira Shinmei (Aorenger), a role arguably overshadowed by this role, in the previous season.
  • Big One is the first Sentai White Ranger.
  • Big One is based on a playing card of joker (from which his predecessor took his nickname) because of using all four power sources of his four teammates and his ability of disguise, which are similar to joker's ability of replacing any other cards in the deck. What is more - both Big One and joker act as additions - the earlier to the team, the latter to the playing cards deck.
  • Although he uses magnetic power like Heart Queen his representation of that power on his suit is yellow instead of pink.
  • He has become the second legendary hero, the first was Akarenger.
  • When he was introduced he immediately became the leader, like Tommy Oliver, the White Ranger in the second season of Mighty Morphin Power Rangers, who was the original White Ranger of Power Rangers just as Big One is the original Sentai White.
  • If one doesn't count Joker as the "yellow" for the team, Banba is the first of two main-team White Rangers to take the yellow position of the main team followed by Sayaka Nagisa of Dengeki Sentai Changeman. All subsequent White warriors after Banba and Nagisa have been classified as either 6th Rangers, Extra Rangers, and Bangai Heroes, or taking the Pink Ranger's place if on the core team with one taking the Green Ranger's place.
  • Sokichi is the only non-Red Ranger to be the center of his team's formation.
  • In post-J.A.K.Q. appearances in which he is prominently featured, Big One's suit is typically padded to cause his pectorals and shoulders to appear large. This padding is typically discarded when a female Gokaiger assumes his identity however.
  • Of all the rangers from J.A.K.Q, Sokichi is the only one who does not have a corresponding rider from the TV series for Kamen Rider BladeIcon-crosswiki'.
