Ninjas have large, humanoid bodies with long yellow spikes for hands and feet. They wear dark gray body suits with white straps wrapping around their chests. Their sleeves flare out wide and end in a pointed fringe reminiscent of Xemnas's crown. They have gray hoods with the Nobody emblem on the front, and a white scarf around their throats. They wear a gray sash belt that drapes down at the front nearly to the floor. Above their spike feet, they wear dark gray chaps with portions of the Nobody emblem which fade from yellow to white.
The Ninja is based on the eponymous job class from Final Fantasy.
Ninjas are fast and swift, and when they receive damage, they tend to jump into the sky and release lightning magic to ward off enemies. Initially, long-range magic such as Water (which it is weak to), Links, and Attractions are the optimal way to defeat these Nobodies. Once Sora is at a high level, direct confrontation is also an option, as his basic Keyblade strikes are now strong enough to take out Ninjas in four strikes. Blocking the end of its Rolling Glide attack allows the usage of Risk Dodge.
