Shinka Organization

Shinka Organization (進化 Organization)is the evil organization which was formed by the mysterious Major GOD. In an attempt to create the ultimate warriors, they were responsible for the rise of Kamen Rider Star Kamen Rider Atar and Orochi Metal, whom defected and became the heroes who would ultimately lead to the fall of Shinka Organization.

==Overview==

Shinka was a cientific organization that planned on ruling the world, with virtually all of its members modified in some way. Shinka's scientists performed surgical alterations that gave the subject superhuman fighting abilities. Even the most basic soldier was tougher, stronger and faster than the average human civilian. The most powerful of their forces were the Human Beasts, modified humans who were combined with animal orinorganic DNA and human cybernetics to create living weapons.

Ruthless and merciless, Shinka would often kidnap prominent scientists and force them to work for the organization, then kill them when their usefulness was at an end (or if they attempted to escape). However, eventually the decision to kidnap and modify the young test pilot Takaishi Akai proved to be their undoing. Trying to modify him into a dragon-human hybrid, he was intended to be another of Shocker's powerful cyborg warriors, but he escaped and began to oppose them as Kamen Rider Star. Later, the organization succeeded in creating a warrior who would counterattack the Rider to finally destroy him, and created Oroshi, a perfect weapon and (at that time) impossible to be reversed from the conversion. However, after a battle against Star, Orochi was able to break free of the brainwashing and joined the Rider to end the organization. The pair became known as the Masked Warriors, who managed to put an end to Shinka.
