Blank Form

is the default, incomplete form of the 13 Kamen Riders when they lack a Contract Monster. It is much weaker than their standard form, though it is enough to keep them from disintegrating in the Mirror World.
Only Ryuki and Ouja (Episode Final timeline)'s Blank Forms have been seen. Ryuki began the series in Blank Form before he contracted Dragredder, and he also reverted back to this form when his Contract Card was stolen by Kamen Rider Gai. Ouja was reverted to Blank Form in Kamen Rider Ryuki: Episode Final after Genocider was destroyed by Kamen Rider Ryuga.
Knight's Blank Form is shown as concept art in the book Kamen Rider Art Collection Hero Hen.

Strangely, in the A.R. World of Ryuki arc in Kamen Rider Decade, the exclusive 14th Rider Abyss was not shown to revert to a Blank Form when his Contract Monster Abyssodon (the combination of Abysslasher and Abysshammer) was destroyed. Similarly, when Ryuki assisted the Geats and Revice Riders against his counterpart, Ryuga did not revert to Blank Form when Dragblacker was destroyed.
