This item represents Shotaro Hidari's transformed form using the Joker Memory and the Lost Driver, which was first seen in the Kamen Rider W FOREVER film. This item can be played on its own by turning the item's face, then press the button on top of the item. In addition, inserting the item in the opposite side of the DX Ziku Driver (sold separately), rotate the belt 360 degrees to activate Armor Time and equip Kamen Riders Zi-O or Geiz the Joker Armor! Rotating the belt again will activate the finisher.
