Crow is a puppet, originally created by by Sasori, but passed onto Kankurō. It resembles a three-eyed, four-armed humanoid with jagged teeth and spiky black hairstyle protruding from the top of its head and framing the sides. In Part I, Kankurō typically keeps Crow wrapped in bandages on his back, and he is able to switch places with it at will using the Body Replacement Technique. Because of Kankurō's enjoyment in installing mechanisms into his puppets, Crow is very offensive, having numerous concealed weapons, including poison-tipped darts and smokescreens in order to blind its opponents. The smokescreens can be made up of poisonous gas to serve a secondary purpose. Crow is also able to detach any of its body parts for separate attacks. In the video games, Crow is shown to be armed with a special flight mechanism that enables it to maneuver high into the air where it could bomb targets from above.
