Karasu (烏, Crow) is Kankuro's first and most trusty puppet. Karasu resembles a three-eyed, four-armed humanoid with jagged teeth and spiky black hair protruding from the top of its head and framing the sides. Karasu wears minimal attire save for the worn-out black shawl that obscures the rest of its body. Kankuro typically keeps Karasu wrapped in bandages on his back, and he is able to switch places with it at will using a technique similar to the Body Replacement Technique. Because of Kankuro's enjoyment in installing mechanisms into his puppets, Karasu is very offensive, having numerous concealed weapons, including poison-tipped darts, kunai, blades and a huge poisoned needle concealed within its head. Karasu has also on occasion released smokescreens in order to blind its opponents. The smokescreens can be made up of poisonous gas to serve a secondary purpose. Karasu is also able to detach any of its body parts for separate attacks. Karasu is shown to be armed with a special flight mechanism that enables it to maneuver high into the air for small segments of time and bomb targets from above.
