While the statues on Grand Zi-O are placed there for an obvious reason (left side Heisei Era, right side Neo-Heisei Era, middle Anniversary series), there are other potential reasons for their placements.

Chest Left Side: Kuuga is the first Heisei Era Rider, Den-O and Kiva appeared in the first Heisei Era team-up film (Climax Deka)

Chest Right Side: Double is the first Neo-Heisei Era Rider, Ex-Aid started the Heisei Generation film series, Build appears in the last Heisei Generations film in the Heisei Era.

Two statues on each side of his waist: Kabuto and Ghost both possess horns.

The position of the statues makes a U shape that follows each Heisei era's Kamen Rider order:
* Heisei: Left shoulder: Kuuga, Left arm: Agito Ryuki, left leg from bottom up: Faiz, Blade, Hibiki, left waist: Kabuto, left side chest: Den-O, Kiva
* Neo-Heisei: right shoulder: Double, Right arm: OOO, Fourze, right leg from bottom up: Wizard, Gaim, Drive, right waist: Ghost, right side chest: Ex-Aid, Build.
Decade is in the middle to serve as a bridge between each side (last Heisei Era Kamen Rider, first to properly start the yearly team ups alongside Double (Movie War/Heisei Generations). Zi-O is on the crown to symbolise his role/dream to be King and he is above them all as he is the one who inherits their powers to become a King.
