Yoroi Akadō

is a Konohagakure shinobi and a teammate of Kabuto Yakushi and Misumi Tsurugi, who later defected and joined Orochimaru and Otogakure.

Personality
Yoroi was a brash and strong-willed ninja who usually felt confident about fighting his opponents and would toy with his opponent frequently. He possessed a very arrogant side and loved to boast about his own abilities. Often times however his toying with opponents led to him losing his struggles rather than emerging with victory. He was also described as being greatly self-confident and unsociable.

Appearance
Yoroi's appearance was greatly concealed by the mask he wore around his mouth that hung to around his neck, sunglasses that obscured his eyes and forehead protector which he wore like a bandanna. He also wore what appears to be the standard attire of his team consisting of a high-collared, sleeveless, purple shirt with a short-sleeved, white one underneath, a simple obi around his waist, purple pants, blue sandals and purple fingerless gloves. After defecting from Konohagakure, he wore a simple shirt with the sleeves rolled up, pants and sandals. It was also revealed that he had black shoulder-length hair.

Abilities
Yoroi's most notable ability was his capacity to absorb the physical and spiritual energy of an opponent by simply coming into physical contact with them. Yoroi was quite proficient with this technique, as he was able able to drain Sasuke's chakra even by just slightly grazing his hair. This extra chakra could also be utilised by himself to perform chakra-taxing techniques.

In the anime, Yoroi demonstrates a greater assortment of techniques such as the Demonic Illusion: Descending Hell Technique, which creates an illusionary ball of fire in the sky to frighten his opponents. He also shows proficiency in water-based techniques, using both the Water Clone Technique and the Water Release: Great Waterfall Flow Technique against Shino. He also demonstrates a technique in which he strikes the ground with his fist and creates a shockwave that paralyses Shino (who was actually an insect clone).

Chūnin Exams
Yoroi, who at the time was in Kabuto's Genin Team, participated in the Chūnin Exams with a task given to him and his fellow teammates by Orochimaru. During the preliminaries he is matched against Sasuke Uchiha. Yoroi utilised a very unique technique that allowed him to absorb the chakra of his opponents, making it very difficult for Sasuke to battle, let alone keep his cursed seal under control. Despite this, Sasuke defeated Yoroi with his newly devised taijutsu, the Lion Combo.

Kaima Capture Mission
Though Yoroi and Misumi are not reintroduced in the manga, they make a second appearance in the anime as research assistants and bodyguards to Orochimaru's former scientist, Amachi. He, like Misumi, has taken off the cloth covering his lower face and has completely changed his wardrobe. Yoroi, too, has displayed a variety of anime-exclusive techniques and different ways of manoeuvring his Chakra Absorption Technique. During the events of this arc, he fights Shino Aburame twice; in the first battle, he is forced to retreat due to the fact that the cave the two were fighting in was collapsing. During the second battle, he is ultimately defeated and sinks beneath the water after a final attack by Shino's bugs. Currently, his status is unknown.
