The Rider Kick's Figure Series (ライダーキックスフィギュアシリーズ,Raidā Kikkusu Figyua Shirīzu, shortened to RKF) is a toy line launching alongside Kamen Rider Zi-O consisting of action figures, with two major component lines. The Rider Armor Series (ライダーアーマーシリーズ,Raidā Āmā Shirīzu) is the main action figure toyline for Kamen Rider Zi-O, featuring Riders and form changes from that series, while the Legend Rider Series (レジェンドライダーシリーズ,Rejendo Raidā Shirīzu) features new figures for past Riders, fitting with the main theme of Zi-O. This cross-series toyline continues through Kamen Rider Zero-One.
The figures have some changes from past "gimmick" toy lines, like the Bottle Change Rider Series and Level UP Rider Series of predecessor series. Firstly, they are slightly smaller, being around 5 inches as opposed to the previous 6 inches. Secondly, rather than articulated hands, they feature multiple static swappable hands, similar to other collector lines.
The tagline for the series is "It's cheap and it moves!"
