Kamen Rider Orga exists in a world where the Orphnochs have taken over the planet and the humans are slowly being exterminated. The Orga gear was given to Yuji Kiba after he had been fooled into thinking he had been betrayed by the humans. The Orga gear was recorded as the fifth Rider Gear created by Smart Brain, after the Faiz and Kaixa Gears were stolen by the humans and the Riotrooper gear had undergone mass-production. Created alongside the Psyga Gear, the Orga Gear is regarded as a 'perfect' gear, and therefore it can only be worn by Orphnochs. Kamen Rider Orga has a more ornate appearance than any of the previous Gears, the Rider form having robes made of Soul Foam for a majestic appearance. Soft parts of the armour are made of Sol Foam, and the hard parts are made of Sol Metal. This substance is generated by the Orga Driver to form complex machinery that is powered by Photon Blood. Photon Blood is glowing substance that provides all of the Riders powers and generates all of the physical features of the armor. The Photon Blood is generated from the Orga Driver and Orga produces even more Photon Blood than Psyga. If the Foam or Metal are damaged, the armor switches off and resets itself. He only transformed with the Gear once however, before he was killed by the Elasmotherium Orphnoch and the Orga gear self-destructed.
