Shotaro Hidari is a self proclaimed "hard-bolied" detective, though called "half-boiled" by many of his pears. Normally he forms the left half of Kamen Rider Double, but when his partner, Philip is abducted he uses a Lost Driver and the T2 Joker Gaia Memory, to assume the identity, Kamen Rider Joker, which bears a strikingly large similarity to Double's Final Form, Kamen Rider Double JokerJoker which Shotaro also controls.

Double Driver
When Decade uses his Final Form Ride card on Double and splits Cyclone and Joker apart, they are both wearing a Double Driver with TWO of the same Memory in both slots.

Lost Driver
With Shotaro unable to use the Double Driver he uses a Lost Driver instead to transform. To transform Shotaro places the Joker Memory in the Memory Slot to transform into Kamen Rider Joker.

Gaia Memory
Joker's sole Gaia Memory is the T2 Joker Memory, which is used for the transformation, and like its predecessor it increases the fighting capabilities of the user.
