Shotaro Hidari

Shotaro Hidari (左 翔太郎 Hidari Shōtarō) is the left hand side of Kamen Rider Double (仮面ライダーダブル Kamen Raidā Daburu), but also a Rider in his own right as Kamen Rider Joker (仮面ライダージョーカー Kamen Raidā Jōkā). A self-proclaimed "hardboiled detective", he dresses in a retro fashion based on late-1930s style, favoring fedora hats and waistcoats. He is often called 'half-boiled' by his friends, however, because he cannot fully shut out his doubts, was initially seen as inexperienced, often acts according to his feelings, and has difficulties making cruel yet necessary decisions, contrary to his hard-boiled aspirations. He later on becomes more respected though, as he proved himself throughout the series. He works as a private detective in the city of Futo.
In the DZ2K series, along with Phillip, he is one of the Kamen Riders debuting in DZ2K19. He's also one of the Legendary Heisei Riders with Phillip.
