In every installment of the Kamen Rider series in the Heisei era, at least one Kamen Rider gains a form that is statistically more powerful or thematically more important, called a Final Form. This is typically reserved for the titular Kamen Rider, but other, non-titular Riders have also obtained a Final Form. The predecessor of the Final Forms came from the Showa era Rider, Kamen Rider Stronger, with his Charge Up form. In recent years, several Kamen Riders have gone on to, usually in movies, access forms that are even further advanced from the Final Form.
