|This article is about a/an form in Kamen Rider Zi-O.|
KuugaArmor (クウガアーマー KūgaĀmā) is a Kamen Rider Kuuga-based form accessed by using the Kuuga Ridewatch in the left-hand side of the Ziku-Driver, invoking Kuuga's Mighty form. Its visor spells out "Kuuga" (クウガ Kūga).
In Heisei Generations Forever, Tid intruded into the Kurougatake ruins on January 29, 2000, a day before the real life premiere of Kamen Rider Kuuga. From Riku's remains, Tid created the Another Kuuga Watch and Geiz did the same with the Kuuga Ridewatch.
- KuugaArmor is the only armor with shoulders' similar to the original rider.
