Kamen Riders' Berserk Forms

This article is about a recurring plot element in the Kamen Rider Series.

A Berserk Form (暴走フォーム, Bōsō Fōmu) is a form that results in the Rider losing control of their own actions while transformed. These are not necessarily forms that the Rider uses in particular moments of rage, but rather exert an influence on their state of mind. The Rider will sometimes overcomes the form's influence or devise an option or entirely new form to avoid it. Sometimes, the Rider is forcibly changed into one of these forms by another person and ceases to use the form after they are set free.
