Leonard Banba

"Big One!"

- Big One's roll call

Sokichi Banba (番場 壮吉) is Big One (ビッグワン) of J.A.K.Q.. He is the ISSIS officer who was called in to take over operations in Tokyo for Joker as J.A.K.Q.'s mobilization leader.

J.A.K.Q.
"Captain of J.A.K.Q. Dengekitai, Sokichi Banba. Nice to meet you."

- Sokichi's greeting to his enemies 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.

Personality
Leonard 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 the Crimebots.

Big One
Dubbed “The White Superman” (白い超人), 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.

Arsenal

 * Big Baton
 * Big Bomber (Big One provides the missile for the team cannon)

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


"J.A.K.Q.!"

- Mobilates' Gokai Change announcement

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. Sokichi received his key and became Big One once more.
