Kidoumaru is best known as the spider-themed member of the Sound Four, and he's basically what you'd get if someone decided to make a ninja genuinely arachnid-inspired. He's got four extra arms on top of his regular two, a third eye, and the ability to produce webs from his body.
The webs themselves are pretty wild—they're made from a special liquid created by mixing his body fluid with chakra, which gives them steel-level durability. He can kick it up a notch with something called Spider Sticky Gold, a golden webbing that hardens into metal when it hits oxygen. Since the material is so solid, Kidoumaru can shape it on the fly into armor or weapons during fights, making him genuinely versatile in combat.
