Jigumo

was one of the members of the Fūma clan who were deceived by Orochimaru. Jigumo's appearance was that of a bald man with long spider-like limbs. He also had very thick eye-brows and a scar on his left eye.

Background
After the Fūma clan finished a war with a neighboring country, they wandered the Land of Rice Fields hoping to settle down. Near the end of their journey, Orochimaru and Kimimaro appeared before the Fūma and told them that if they joined Otogakure that Orochimaru would help in restoring their power. Jigumo, along with Kamikiri, Kotohime, and Kagerō Fūma, were enchanted by this idea and, under Arashi Fūma, decided to go with Orochimaru, hoping they could regain their power.

Fūma clan arc
Jigumo was one of the three-member group who guarded Orochimaru's base in the Land of Rice Fields, alongside Kamikiri and Kagerō. When Arashi's cousin, Sasame Fūma, fled to the base, Jigumo and the others told her to capture the three ninja sent from Konohagakure (Naruto Uzumaki, Sakura Haruno, and Jiraiya) and bring them to Orochimaru. During their first attack on the Leaf ninja, Jigumo used his Wind Spiders Technique to trap Sakura and Sasame (unintentionally) inside the hut they were staying in. Naruto tried to fight Jigumo off with a Multiple Shadow Clone Technique, but Kagerō used Earth Release: Antlion Technique to stop him. They were driven off by one of Jiraiya's toads.

Later, after Sasame tricked the Leaf ninja into drinking drugged drinks, she discovered that Jigumo and his partners actually intended to kill them to show their usefulness to Orochimaru. However, it turned out that the ninja had known about the drugged drinks and fought against the three traitors. Jigumo fought against Jiraiya but was then defeated by the Rasengan. After regaining consciousness, Jigumo and Kamikiri brought a near-death Kagerō to Orochimaru and begged them to heal her. Orochimaru refused their request due to their failure of killing the Leaf ninja. Angered at his refusal to save Kagerō, Jigumo attacked Orochimaru but was easily killed by him along with Kamikiri.

It was revealed later that "Orochimaru" was actually the now power-crazed Arashi in disguise. When Arashi, disguised as Orochimaru, killed Jigumo, he absorbed him and Kamikiri into his body and he became a revolting monster. After the monster was defeated through the efforts of Sasame, Naruto, and Sakura, the lair began to collapse. The last seen of Jigumo and Kamikiri was his sentient flesh trying to devour Arashi.

Abilities
Like Kidōmaru, Jigumo used spiders and spider webs in combat and for scouting via his, though his skills were not on the same level. He was however able to spit spiders and webs from his mouth. To add to his spider-like traits, Jigumo climbed on trees and other surfaces on all four limbs.
