Kamen Riders' Base Forms

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

In certain Kamen Rider Series, there are Riders who have access to a default form before they alternate between their Main Forms. Usually the Rider's default form is commonly used along with the other Main Forms, while some other riders include a base that gives access to alternate forms that offer slight advantages over the base form, such as added strength in return for lowered speed, etc.

The combat capabilities of Base Forms vary. While some riders (Agito, ZECT Riders, Ixa, Accel, Fourze, and Beast) are perfectly capable of holding their own in their Base Forms, other Riders' (Den-O) Base Forms are rather weak in comparison to their other forms.
