Complete Form (コンプリートフォーム Konpurīto Fōmu?) is the final form accessed via the K-Touch device first by Decade, and then Diend, utilizing the powers of a group of Kamen Riders (the Nine Heisei Riders in Decade's case and eight Movie Riders in Diend's).

- Weight: 102kg

- Decade's Complete Form is able to manipulate the power of other Riders' final forms, accessed through the K-Touch once he regains the powers of all of the Heisei Kamen Riders. Referred to as the "King of the Rider Worlds", he wears the Decade Complete Kamen Ride Card on his helmet, embedded in the Decade Crown, and the others' Kamen Ride Cards on his chest.
- When Complete Form features the most powerful forms of the Heisei Kamen Riders (which is done by replacing Kuuga Ultimate with Kuuga Rising Ultimate and Den-O Liner with Den-O Super Climax) on the cards (as seen in the Super Adventure DVD, and Movie War 2010), this version of Complete Form is called Strongest Complete Form (最強コンプリートフォーム Saikyō Konpurīto Fōmu?).

- Decade's Complete Form and Gokai Silver's Gold Mode of Kaizoku Sentai Gokaiger were noted by Narutaki as one of the similarities between Decade and Gokaiger in the Super Hero Taihen net movie The Grown-ups’ Narumi Detective Agency Ep. 1: Is Gokaiger a Ripoff of Decade?, this similarity understandably came as the biggest shock to Gokai Silver, who posed the question in the first place.
