Rider Black premiered in 1987, the first series not hinting at a relationship to its predecessors. Black was the first show in the franchise with a direct sequel: Kamen Rider Black RX, the basis of Saban's Americanized Masked Rider. In RX finale, the ten previous Riders returned to help Black RX defeat the Crisis Empire. Kamen Rider Black RX was the final show produced during the Shōwa era, with the franchise resuming production by the end of the 20th century. A manga of Kamen Rider Black was a novelization and reimagination of the Black-RX series' continuity. Absent from television during the 1990s, the franchise was kept alive by stage shows, musical CDs, and the Shin, ZO, and J films. Heisei era Phase 1 Toei announced a new project, Kamen Rider Kuuga, in May 1999. Kuuga was part of Ishinomori's 1997 Kamen Rider revival in preparation for its 30th anniversary, but he died before the shows materialized. During the summer of 1999, Kuuga was promoted in magazine advertisements and TV commercials. On January 30, 2000, Kamen Rider Kuuga premiered with newcomer Joe Odagiri. Following Kuuga 2001 sequel Kamen Rider Agito, the series deviated into a series of unconnected stories starting from Kamen Rider Ryuki in 2002 to Kamen Rider Kabuto in 2006. In 2005, Kamen Rider: The First was produced. Written by Toshiki Inoue, the film reimagines the manga and original television series and characters from the original series had their storylines altered to fit the film's time span. Masaya Kikawada played Takeshi Hongo/Kamen Rider 1 and Hassei Takano (previously Miyuki Tezuka/Kamen Rider Raia in Kamen Rider Ryuki) was Hayato Ichimonji/Kamen Rider 2. This was followed in 2007 by Kamen Rider The Next, an adaptation of Kamen Rider V3 starring Kazuki Kato (previously Daisuke Kazama/Kamen Rider Drake in Kamen Rider Kabuto) as Shiro Kazami/Kamen Rider V3 and with Kikawada and Takano reprising their roles. The eighth series, Kamen Rider Den-O, followed in 2007. It differed from past Kamen Rider series with the main protagonist being unsure of himself and uses a large vehicle, the DenLiner: a time traveling bullet train. Although the series has only two riders (Den-O and Zeronos), they have multiple forms similar to Black RX, Kuuga, and Agito. Due to Den-O popularity, a second film crossover with the 2008 series Kamen Rider Kiva was released on April 12, 2008. The top film in its opening weekend, it grossed
