Yoroi Akadō

Yoroi Akado is a part of the three-man team of ninja from Otogakure posing as ninja from the Konohagakure, along with Kabuto Yakushi and Misumi Tsurugi. His name (meaning armor) along with Kabuto (Helmet) and Tsurugi (Sword), they make a helmet-armor-sword trio.

Chunin Exams
Yoroi along with the rest of his team are asked to get information on Team Kakashi in the Forest Of Death, mainly Sasuke Uchiha.

With the Chakra Absorption Technique he can absorb the physical and spiritual energy of an opponent on contact. He used this ability against Sasuke Uchiha during the preliminary matches of the Chunin Exams, making it very difficult for Sasuke to keep his cursed seal under control. Despite this, Sasuke defeated Yoroi with Taijfinishing him off with his newly devised tiger

Combo.

Sea Country
Though Yoroi's fate after the preliminary round against Sasuke has never been comfirmed in the Manga, in the Anime, he makes a second appearance with Misumi in the Land of the Sea filler arc, where he is depicted as a research assistant to Orochimaru's scientist, Amachi. He has taken off the cloth covering his lower face, appearing much older with a very defined facial structure. His hair has appeared to have grown longer and he wears a completely different wardrobe. He kidnapped Isaribi and was traced by Shino Aburame, Naruto Uzumaki, and Ino Yamanaka, who reconize him from the Chunin exams. According to Yoroi, neither he or Misumi have seen their former partner Kabuto since then. It has never been explained why they left Otogakure. During the battles in the arc, he uses Demonic Illusion: Descending Hell Technique to create the illusion of an enormous ball of fire in the sky that impacts the ground in an attempt to drive the Konoha ninja off. Despite his efforts he is forced to battle Shino twice, at which point he uses Water Release: Huge Explosion Technique to try and capture Shino in an inescapable torrent of water. He is ultimately defeated and sinks beneath the water after a final attack by Shino's bugs. As Naruto's group turns their attention away from him afterward, his status remains unknown, though it's highly likely that he drowned due to Shino's bugs cutting off his oxygen supply by going down his throat.

Abilities
Yoroi is a competent ninja and his most notable technique is the Chakra Absorption Technique with which he can absorb the physical and spiritual energy of an opponent on contact. This extra chakra can be used to perform techniques that drain a lot of Yoroi's chakra. During the Land of the Sea filler arc, he shows a better assortment of techniques: Demonic Illusion: Descending Hell Technique, which creates a ball of fire in the sky. He is also shown profiency in water-chakra from creating Water Clones and is also seen using Water Release: Huge Explosion Technique to try and capture Shino.
