Blue B

Blue B had long bi-colour hair (half green half white) with matching eyebrows along with heavy-lidded eyes that give him the appearance of being very tired. He had a purple mark in the shape of a diamond down the right side of his face. He wore the standard attire of the Kumogakure shinobi including a flak jacket, over a long-sleeved v-neck outfit with bandages underneath and carried a fairly long sword strapped to his back. After being reincarnated, he looked like he did while alive with the exception of pupil-less eyes and grey sclerae.

While an excellent shinobi, Blue B didn't have complete control over the Eight-Tails, a fact he lamented while on a mission alongside A and Killer B. He stated that neither him, nor his uncle or father could subjugate the beast due to "incompatibility". He hoped, however, that B, should he be chosen as the next host, would be able to successfully control the beast. As A wondered if B would have enough control to be able to suppress the beast, Blue told him of the darkness and loneliness that was part of being a jinchūriki. A protested calling him a man of great talent, virtue and lineage, which Blue said none of that mattered and what a jinchūriki truly needed was something to give them strength and fill the void that would be created after the beast was sealed into them. Some time later, in the anime, he was sent on a mission with A and B where they confronted several Iwa ninja, after defeating them Blue B explained to an exhausted B where A's strength came from. At some point after this, he lost complete control of the beast and it killed eight Kumo ninja, including Motoi's father who was a member of the subduing team. The Third Raikage subdued the Eight-Tails by sealing it into the Kohaku no Jōhei, resulting in Blue's death. In the anime, it was Orochimaru who caused the events leading to Blue B's death by posing as his doctor and giving him genjutsu-inducing pills to paralyse him and proceeded to use the Five Elements Unseal to draw out the tailed beast. Later, during the battle that followed, Orochimaru retrieved traces of the Eight-Tails' severed horn along with Blue B's DNA in it. The villagers later lamented Blue B being a failed jinchūriki at his funeral while B paid his respects.
