Hero Legacy: Kamen Rider 00 (ヒーローレガシー:仮面ライダーダブルオー,Hīrō Regashī: Kamen Raidā Daburu ō) is a fan-made TV series adaptation of the Kamen Rider Franchise, written by H_barcenas and posted on the Kamen Rider Fanfiction Wiki Page. It is the spiritual sequel to Kamen Rider W, taking place in the City of Fuuto, 20 years after the events of the main series. The fanfiction also serves as the second entry to the Kamen Rider Heroes continuity, making it a direct sequel to Hero Retold: Kamen Rider Shinobi, following its conclusion in 2020.


Year 2020, a horrific incident called the Gaia Bombing leveled the City of Fuuto, causing massive destruction to its structures and deaths to thousands of its inhabitants. Ten years later, the once ecological landmark has yet to fully bounce back as efforts to revitalize the city has been met with resistance by its rising criminal activities, headed by the mysterious organization CENTER and the much more powerful High Dopants.

Enter Yusaku Amasawa, a young high school student running away from his mysterious past, before being thrust in as the new symbol of hope for its citizens after its original protectors had mysteriously disappeared. Now bearing the title of Kamen Rider 00, he faces these new threats while also uncovering a grand conspiracy that will ultimately lead him to confront his demons. Fuuto's story continues into this dark chapter.
