Kamen Rider Zi-O (仮面ライダージオウ, Kamen Raidā Jiō) is a Japanese tokusatsu drama in Toei Company's Kamen Rider Series. It is the twentieth and final entry of the Heisei Era, serving to commemorate its 20th Anniversary, and the thirty-third series overall. The series premiered on September 2, 2018 and joined Kaitou Sentai Lupinranger VS Keisatsu Sentai Patranger in the Super Hero Time line-up after the finale of Kamen Rider Build. After Lupinranger VS Patranger’s conclusion, it was joined by 4 Week Continuous Special Super Sentai Strongest Battle!! in February 2019 and later Kishiryu Sentai Ryusoulger in March 2019.
The motif of the series is time. The series' tagline is "I will become the king of Kamen Riders!" (俺は仮面ライダーの王となる！, Ore wa Kamen Raidā no ō to naru!). Much like Kamen Rider Decade, it commemorates all of the Heisei-era Kamen Riders to date.
The average rating of the series was 3.0%
