"Big One!"

Big One Age: 24 years old

Actor: Hiroshi Miyauchi

Birthday: June 14, 1942

J.A.K.Q.
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. 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. 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.

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 Gorou 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 Goseiger 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 Kaijou 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.

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.

Super Hero Taisen
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.

Big One
Dubbed  “The White Superman” (白い超人, Shiroi Chojin), as Big One Sokichi's enhanements 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 Kyouka Capsules; instead taking a sniff out of a magical red rose.

Design
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
The Big One Ranger Key (ビッグワンレンジャーキー) 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.
 * Joe became Big One alongside Luka (GaoWhite) and Ahim (White Swan) as part of an all-white change in their fight against Action Commander Salamandam.
 * When the Gokaigers became JAKQ in their fight against Action Commander Zaggai.
 * When the Gokaigers became JAKQ in order to use the Big Bomber cannon against Action Commander Shieldon in a vain attempt to penetrate his shield.
 * Marvelous beame Big One as part of an all-white Gokai Change in the Gokaigers' fight with Makuu Prison Chief Ashrada.

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.

After Zangyack were finally defeated, the Gokaigers gave the Ranger Keys back to their rightful owners. It is presumed that Sokichi received his key and became Big One once more.
