Shin Kazamatsuri

Kamen Rider Shin (仮面ライダーシン) is the main protagonist in the Japanese tokusatsu movie Shin Kamen Rider: Prologue.

Shin Kazamatsuri
Shin Kazamatsuri (風祭 真), is a motorcycle racer who gave everything up to volunteer for his father's experiment, not knowing the true ambitions of his father's partner or the organization they worked for. He struggles to uncover the conspiracies, not completely knowing just how much his loved ones are truly involved. He overcame many enemies and learned how to control the mutant, but was covered with sadness in the death of his girlfriend, his friends, and ones who had helped him in escape from the FBI and the Syndicate who hunted him.

In the end he fought Cyborg Soldier Level 2 and when he tore the monstrous humanoid's head, it has a bomb in it. Shin quickly threw the head and after a short final confrontation with FBI and The Syndicate, he takes his girlfriend's body and surprisingly his child inherits his mutation, causing Shin to be able to communicate to his child. Shin smiles and takes his girlfriend's body, following the light that guided him from the child.

All Riders vs. Dai-Shocker
Shin, along with every other Showa Rider, appears in Kamen Rider Decade: All Riders vs. Dai-Shocker. In the Internet spinoff films accompanying the movie, Shin is identified as the 13th official Kamen Rider of the Showa era.

Let's Go Kamen Riders
A mishap caused by the Greeed Ankh unintentionally altered the timeline which enabled Shocker to utilize the Core Medal to create the Shocker Greeed which defeated the Double Riders and seemingly erased the legacy of the Kamen Riders from history. In 2011, after Kamen Rider New Den-O's attempt to repair the damage, he along with Kamen Rider OOO and M-Ankh awaited execution. However, it was revealed the Double Riders had their brainwashing removed by a Shocker scientist.

The Double Riders joined with New Den-O and OOO to fight Shocker's forces, but were eventually defeated. When the order was given to kill everyone, V3 suddenly appeared, asserting that there were more than four riders. V3 was soon followed by all the other revived riders that came after him, including Shin, as even though Rider history was changed, the people's memories haven't changed.

After the riders were united, they faced off against Shocker's Great Leader. Later, when joined by a force of extra riders, Shin and all the other riders got on their motorcycles and performed the "All Rider Break", ramming into the Rock Great Leader and defeating it once and for all.
 * Although Shin's human form isn't shown in the movie itself, he has no lines and isn't listed in the credits, Shin is confirmed to be Shin Kazamatsuri by the movie's official website.

Kamen Ride Cards
Kamen Ride Shin (カメンライドシン) is the Kamen Ride Card which contains the power of Kamen Rider Shin. In All Riders vs. Dai-Shocker, Decade Complete Form Jumbo Formation performed the Final Dimension Kick, a variation of the Dimension Kick, transforming the Shōwa Riders, including Shin, and Heisei Riders into Kamen Ride cards for Decade to travel through as opposed to Final Attack Ride cards before hitting the target.

In theory, this card would allow Kamen Rider Decade to transform into Shin.

Kamen Rider Gaia
Before the name "Kamen Rider Shin" was decided, Shotaro Ishinomori originally planned for the character to be called "Kamen Rider Gaia" (仮面ライダーガイア). The design of this Kamen Rider Gaia was originally of more a traditional Kamen Rider appearance, before later designs switched to a "Kamen Rider Style Reform" version (resembling a man in a motorcycle helmet and modified riding jacket), and then the mutated insect-like human that would become Kamen Rider Shin. This concept would later be used for Kamen Rider Eve -Masked Rider Gaia- and its protagonist Jun Kadowaki, and for a Kamen Rider character in Kazuhiko Shimamoto's Skull Man manga.
