GhostArmor (ゴーストアーマー GōsutoĀmā) is a Kamen Rider Ghost-based form accessed using the Ghost Ridewatch, invoking Kamen Rider Ghost's Ore Damashii. When summoned, it is projected in a holographic Eyecon and does Ghost's signature pose before dispersing to attach to the user. The GhostArmor's Eyecon Shoulders (眼魂ショルダー Aikon Shorudā) are modeled after Ghost Eyecons, and depending on whether it is used by Zi-O or Geiz, its visor spells out "Ghost" (ゴースト Gōsuto) in katakana or "Ghost" (ごーすと Gōsuto) in hiragana respectively. Once equipped, the user gains some of Ghost's powers including floating, intangibility and the ability to summon Parka Ghosts.[1]

Later, Geiz lent the Ghost Ridewatch to Zi-O so he could appropriately fight Another Ghost, with Zi-O swapping his GaimArmor for the GhostArmor while Geiz continued in WizardArmor. and so loaned him the Ghost Ridewatch to assume GhostArmor. Zi-O and Geiz quickly overwhelmed Another Ghost but were stopped just short of performing their respective finishers when Heure revealaed that to defeat the Another Rider would kill him. In this moment of hesitation, the two Riders were assaulted by the Flame Saber of Kamen Rider Decade: Agito Ground Form.
