Sokichi Banba

"Big One!"

Soukichi Banba (番場 壮吉, Banba Sōkichi) is a flamboyant playboy and master of disguise. He is the ISSIS officer who was called in to take over operations in Tokyo for Joker, as Banba had helped Joker implement the JAKQ project. He is himself a cyborg and is in fact considered the ultimate “super cyborg” for his bionic implants allowed him to harness and manipulate all four cosmic powers (atomic, magnetism, electricity and gravity).

J.A.K.Q.
Banba's nickname was the “The White Superman” (白い超人, Shiroi Chojin). He can direct his powers to perform a variety of incredible feats including flying, superhuman strength and super speed. Banba 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.

Banba is unique in that he can transform at will without the use of the Kyouka Capsules and instead takes a sniff out of a magic red rose.

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 appeared with the other Reds, the two did not interact.

Gokaiger
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.

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.

After the Gokaigers defeated the second Zangyack invasion, Marvelous returned the Ranger keys to the Super Sentai, so it is assumed Soukichi and his team have their powers back.

Super Hero Taisen
Soukichi, 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.

Ranger Key
The Big One Ranger Key (ビッグワンレンジャーキー) is Soukichi 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.

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