|This article is about a/an form in Kamen Rider Zi-O.|
Ex-AidArmor (エグゼイドアーマー EguzeidoĀmā) is a Kamen Rider Ex-Aid-based form accessed using the Ex-Aid Ridewatch, invoking Kamen Rider Ex-Aid's Action Gamer Level 2, and wielding the Gashacon Breaker Breakers (ガシャコンブレイカーブレイカー Gashakon Bureikā Bureikā). When summoned, it is projected in a holographic Rider Gashat and does Ex-Aid's signature pose before dispersing to attach to the user. Ex-Aid Armor's Gashat Shoulders (ガシャットショルダー Gashatto Shorudā) are modeled after Mighty Action X Rider Gashats, and depending on whether it is used by Zi-O or Geiz, its visor spells out "Ex-Aid" (エグゼイド Eguzeido) in katakana or "Ex-Aid" (えぐぜいど Eguzeido) in hiragana respectively.
Much like Ex-Aid himself, the armor can generate Game Areas and create item blocks that Zi-O or Geiz can use as platforms and much like Action Gamer Level 2, grants its user great agility and jumping ability. The only difference from Ex-Aid is that when the Rider using the Armor attacks, the "Hit!" and other effect words that are projected are in katakana (ヒット！) or hiragana (ひっと！) rather than in English.
