The Delta Armor has several key features in its design. Unlike the Gear, the armor only exists after the wearer transforms.
*Full Metal Lung: The vest armor of the Rider provides the most protection, being able to withstand Anti-tank weaponry.
*Global Feeler: The antenna on the Rider’s head can be used to communicate with the Smart Brain Satellite and the Smart Brain computer network.
*Photon Blood: A glowing substance that provides all of the Rider’s powers and generates all of the physical features of the armor. The Photon Blood is generated from the Delta Driver.
*Photon Streams: The path that the Photon Blood travels through the Rider’s armor. In Delta, this path is blue when transforming, white after transformed.
*Photon Terminals: Where the Photon Streams connect with the gauntlets and greaves.
*Sol Foam/Metal: Soft parts of the armor are made of Sol Foam, and the hard parts are made of Sol Metal. This substance is generated by the Delta Driver to form complex machinery that is powered by Photon Blood. If the Foam or Metal are damaged, the armor switches off and resets itself.
