Ninja Pirates, also known as Ninja Henchmen, are a type of Robo-Pirate that appear in Rayman 2 and all of its remakes.

Ninja Pirates appeared as a mini-boss two times in the original version of Rayman 2, one in the Precipice and another in the Prison Ship. They use a flame-thrower or the purple Robo-Pirate bullets. They are more dangerous and clever than all the other Robo-Pirates and strike like phantoms, making each one a master of stealth who can't be seen with the naked eye until they are right in front of (or behind) Rayman.

In Rayman 2: Revolution they are referred as the Generator Guardians of the two generators of the Pirate Factory and have unlimited heath. They fire the same bullets as the Green Robo-Pirates, but they are more accurate and faster. These pirates wear a red bandanna, have a black torso, have a cylinder for a head, a white eye and an eye patch.

In the PlayStation version, they appeared four times as mini-bosses in the Precipice, the Tomb of the Ancients, and Gloomy Island. Rayman also fights their leader, Ninjaws, in the Sanctuary of Stone and Fire.

The interesting thing in their appearance is that their hands have textures of tighted fists, although they have hook in right hand, growing up from the fingers, and they can shoot with the flames from their left hands, like normal henchmens - although it looks like they're shooting from their fingers.

In Rayman Revolution, two Ninja Henchmen can be seen standing on either side of Admiral Razorbeard's chair in the Prison Ship cutscenes. Rayman encounters these Ninja Henchman later on in the game – they attempt to defend the electrical generators in the Precipice and the Echoing Caves from him. During the battles, they appear very briefly, shoot at Rayman, then teleport away for a few seconds before repeating the cycle. They are much less powerful and aggressive than Ninjaws. Once Rayman destroys the generators, he can enter the Pirate Factory. After Rayman has destroyed the generators, these two Ninja Henchmen are absent in the next Razorbeard cutscene, regardless of whether Rayman actually destroys them or not. Admira
