is the primary and eponym protagonist of the 2011-2012 Kamen Rider Series Kamen Rider Fourze. Kamen Rider Fourze's name is meant to resemble the number 40, as Fourze serves as a 40th anniversary for the Kamen Rider Series and there are 40 different powers he can access. The series also commemorates the 50th anniversary of manned spaceflight, lending itself to Kamen Rider Fourze's spacecraft-inspired design and arsenal.

Kamen Rider Fourze makes his debut appearance in Kamen Rider OOO Wonderful: The Shogun and the 21 Core Medals where he assists Kamen Rider OOO fight the film's antagonist Gara and tells Kamen Rider OOO that he will befriend all Kamen Riders.

is a second-year transfer student at Amanogawa High School who looks like the delinquent yankee, wearing a short jacket over a T-shirt and baggy pants, with his hair in a pompadour, rather than the clean cut uniform worn by other AGHS students. Despite his outlandish appearance, Gentaro is very sociable and willing to make friends with almost everyone he comes across, even going the extra mile and do bizarre things to get to know someone he wants to befriend better. He puts friendship above anything else and values every friend that he has, to the point of crying hard whenever he hears a sad story of someone he considers a friend.

On his first day at AGHS, he reunites with his childhood friend Yuki Jojima, and Gentaro makes it his objective to befriend loner Kengo Utahoshi, who goes out of his way to avoid him. Gentaro's search for Kengo results with him getting into a confrontation with Miu Kazashiro and Shun Daimonji until a strange creature Yuki identifies as a Zodiarts appears. Though he appears to have been knocked out while fighting off the monster, Gentaro sees Kengo's arrival in the Powerdizer exo-suit and later follows him and Yuki to an abandoned part of campus where they enter a locker that transports them to a lunar base known as the Rabbit Hatch where the Fourze Driver is being kept. Gentaro takes the item after hearing Kengo speak of his difficulty in manning the Powerdizer, and then faces off against the Zodiarts as Yuki instructs him on how to use the driver. Transforming into Kamen Rider Fourze, Gentaro is able to defeat the Zodiarts, and he is begrudgingly allowed to keep the Fourze Driver in order to battle the Zodiarts menace. To cement his new friendship with Kengo, inspired by Tomoko Nozama's presentation of an urban legends website she found that details the deeds of Kamen Riders for the previous 39 years, Gentaro forms the Kamen Rider Club while taking up the title of Kamen Rider.

Kamen Rider Fourze has not been a contender in any CBUB matches.
