Heisei Kamen Rider 15th Anniversary

The Heisei Kamen Rider 15th Anniversary (平成仮面ライダー15周年) was commemorated from Fall 2013 to 2014 with the broadcast of Kamen Rider Gaim, the fifteenth entry of the revived Heisei Kamen Rider Series. The addition of Gaim was of particular significance in that the number of protagonist Heisei Riders now equaled that of the officially recognized Showa Riders.
 * Kamen Rider Gaim was introduced in a two-part arc closing the preceeding series Kamen Rider Wizard: The Kamen Rider Rings and Neverending Story. Featuring the return of Masahiro Inoue as Heisei Kamen Rider 10th Anniversary protagonist, Kamen Rider Decade, this episodes depicted a union of the first 15 Heisei Riders.
 * In December, Kamen Rider × Kamen Rider Gaim & Wizard: The Fateful Sengoku Movie Battle featured the 15 Bujin Riders, alternative incarnations of the Heisei Riders.
 * In March 2014, the film Heisei Rider vs. Showa Rider: Kamen Rider Taisen feat. Super Sentai featured a clash between the 15 Showa Riders and 15 Heisei Riders.
