The NZ-666 Kshatriya (クシャトリヤ, Kushatoriya), aka the "Quad-wing", is a mobile suit featured in the novel and OVA series Mobile Suit Gundam Unicorn. It was piloted by Marida Cruz.

The Kshatriya was designed with the intention of miniaturizing the NZ-000 Queen Mansa - which was more than 40 meters tall - while retaining its performance. This was done through the implementation of new technology, including the installation of Psycho-Frame around its cockpit. Since Neo Zeon lost the ability to manufacture Psycho-Frame following the Second Neo Zeon War, the Kshatriya became a one-off unit. Another factor that contributed to its miniaturization was that most of its functions are concentrated in its four wings/binders. As a result, the Kshatriya was almost half the size of its predecessor. The four massive wings/binders are also the Kshatriya's greatest features, each containing two mega particle cannons, a funnel container with six funnels, an I-Field generator, flexible thrusters, a propellant tank, and a sub-arm equipped with a small beam saber. Each wing/binder also serves as an AMBAC unit. Like its predecessor, the Kshatriya requires a powerful Newtype pilot.
