Decade can transform into any previous Kamen Rider with access to that respective Rider's powers and weapons. However, during the battle against Kamen Rider Dark Kiva in the Nega World, Tsukasa had lost his power to transform into Kamen Rider Decade as well as all the Rider Cards losing their power and turning black. Later, Tsukasa was able to restore his power and all the cards returned to normal. One of Tsukasa's particular gestures is dusting his hands, or running a hand along the blade of his sword, while fighting.

Violent Emotion
Violent Emotion "Kamen Ride: Decade!"

- Transformation announcement

For most of the first act of Kamen Rider × Kamen Rider Double & Decade: Movie War 2010, Decade assumes his dark rider form called Kamen Rider Decade Violent Emotion (仮面ライダーディケイド激情態). This form is Decade's false final transformation into the destroyer of worlds, with the eyes assuming a more sinister appearance, and the normally yellow Signal Pointer (the light on Decade's helmet) is violet. While this form appears similar to Decade's normal form, it is drastically stronger, both possessing greater combat capability (enough to go toe-to-toe with Kuuga Ultimate Form and destroy countless other riders) and able to use Attack Ride cards such as Clock Up without having to transform into the associated Rider first. This form is apparently no longer accessible as Tsukasa's "role" as a destroyer was fulfilled and then negated with the survival of the Multiverse and restoration of the primary Kamen Rider Universe.
