The Walking All-Rider Album (歩く完全ライダー図鑑 Aruku Kanzen Raidā Zukan) is the twenty-first episode of Kamen Rider Decade. It is the concluding part of the World of Negatives arc, as well as the debut of Decade's Final Form, Complete Form. Due to the reduced length of Decade, this marks the earliest debut for a protagonist Rider's Final Form in the Heisei Kamen Rider Series.
