FaizArmor (ファイズアーマー,Faizu Āmā) is a Kamen Rider Faiz-based form accessed using the Faiz Ridewatch. When summoned, it is projected in a holographic Faiz Phone and does any of Faiz's poses (i.e., the wrist flick or kneeling) before dispersing to attach to the user. FaizArmor's Phone Gear Shoulders (フォンギアショルダー,Fon Gia Shorudā) are modeled after the Faiz Phone, and depending on whether it is used by Zi-O or Geiz, its visor spells out "Faiz" (ファイズ,Faizu) in katakana or "Faiz" (ふぁいず,Faizu) in hiragana respectively.
The Faizphone X interacts with FaizArmor, allowing the form to access the Faiz Shot Shot (ファイズショットショット,Faizu Shotto Shotto) and the Faiz Pointer Pointer (ファイズポインターポインター,Faizu Pointā Pointā), replicas of the SB-555C Faiz Shot and the SB-555L Faiz Pointer.
After receiving the Faiz Ridewatch from Takumi Inui, Sougo gave it to Geiz to fight Another Faiz in 2003 while he fought Another Fourze in 2011. Geiz defeated Another Faiz with an Exceed Time Burst. 555・913・2003
Facing Another Kikai, a persistent Another Rider with no host, Geiz used FaizArmor's Exceed Time Burst to defeat it temporarily. Though Geiz yet again found human host, the true miniature form of Another Kikai had already escaped unbeknownst to him. It's Kikai! 2121
