Renkotsu

Renkotsu (煉骨, Renkotsu) is the second in command and is the third strongest member of the Band of Seven. He became resentful of Bankotsu's power and dares to betray him. After Ginkotsu self-destructed to save Renkotsu from Koga, Renkotsu took Ginkotsu's shard and stuck it in his wounded shoulder. Later, he killed the injured Jakotsu after his battle with InuYasha and took his jewel shard. As punishment for hiding the shards and killing Jakotsu, Bankotsu kills him. Renkotsu was an expert with explosives and metallurgy who used bombs, cannons, wires that will be lit afire, and a special concoction that he drinks to spit fire. He was also a gifted strategist, and possessed some skill at hand to hand combat although the only members of the group he surpassed in fighting skills was Mukotsu and Kyokotsu. He was also skilled at mechanical work, to the point of being able to reconstruct Ginkotsu into a living artillery weapon resembling a modern tank.
