Final Kamen Terminal K-Touch

The Final Kamen Terminal K-Touch (ファイナルカメン端末ケータッチ) is a special touchscreen cell phone. Originally from the World of Negatives in the possession of the Dark Riders, the K-Touch was designed to attach onto the Decadriver replacing the card slot, which is moved to his right hip, allowing Decade to transform into Complete Form. In this form, Decade can still use his Ride Cards by inserting them in the card slot and touching its visor, allowing Decade to summon the powers and weapons of the ultimate form of any of the previous Kamen Riders. When a Rider is summoned, the cards on Complete Form's chest and shoulders change to match the Rider's specific Kamen Ride card and the summoned Rider copies Decade's motions. When activating the K-Touch's functions in Complete Form, any of the Nine Heisei Riders present will be transfomed into their most powerful form. As shown in SIC Hero Saga, World of Stronger, the K-Touch can be used in Decade's default form to allow himself to turn into one of the Rider's strongest forms.
