 * Unique traits: Six arms, able to make webs out of a special liquid and chakra, able to excrete a chakra-blocking liquid from his pores that solidifies into a metal

is the spider-like member of the Sound Four; he possesses four extra arms for a total of eight limbs, and has the ability to make webs. He makes his webs through a special type of liquid that is created by infusing body liquid with chakra. He can also create a thicker gold liquid that hardens into a chakra-blocking metal. This hardened material can be fabricated into body armor, kunai, or his especially deadly bow and arrow. When in his Level 2 cursed seal form, he becomes even more spider-like; his skin becomes darker, and he grows long, white hair. He opens the third eye on his forehead to improve his accuracy (which he normally keeps covered with his Sound forehead protector). He also gains the ability to control the path of his arrows with chakra and thread. His abilities are not kekkei genkai, but clan-related.

Kidomaru is an excellent tactical analyzer, capable of figuring out his enemy's weak point quickly and efficiently, and also enjoys playing with his enemies before he kills them. He seems to prefer fighting from a distance, lending him a considerable advantage and allowing him to avoid close-combat.

Kidomaru generally sees a battle as a game, and often plays around with the opponent too much because he prefers to have fun seeing the opponent struggle. His speech also reflects this- when battling Neji, he, instead of calling Neji "trash", called him a trash character. He also analyzes his predicament using the same language as the typical gamer.

During the Destruction of Konoha arc, Kidomaru used his webs to protect the Sound Four and Orochimaru as they escaped. He was defeated and killed by Neji Hyuga during the Sasuke Retrieval arc, to whom he spoke before dying about it being impossible to save Sasuke, as Sasuke went into the Darkness by his own choice. Although Neji denies this, this turns out to be the exact truth.
