The Ninja Warriors are one of the divisions of the Kung Zhu branch of Zhu Zhu Pets. In the U.S., the Ninja Warriors are made up of Drayko, Yama, Azer, and Thorn, but other ninja hamsters may be available internationally.

There are also two subdivisions within the Ninja Warriors: Azer and Thorn are part of the Skull Tribe, while Drayko and Yama are part of the Dragon Clan.

The Ninja Warriors have a traditional "ninja" theme, in contrast to the Special Forces. Their playsets have a red and black color scheme. These include two ninja-style training courses, a Ninja Dojo Base, and a Snake Pit.
