Naraku....an evil youkai who has quite a history. He was once a man named Onigumo, who was a theif and had suffered extreme burns and could not move. Kikyo had found him in a cave and cared for him, he grew to want the jewel and Kikyo. He offered his soul to hungry youkai and then became... Naraku. He then diguised himself as Inuyasha and fatally wounded Kikyo, he also disguised himself as Kikyo and shot at Inuyasha, turning them against eachother. He had hoped to take the jewel after they were both dead, but Kikyo had it burned with her when she died. Now the jewel is back and Inuyasha still lives. He has found many jewel shards and was even given a huge piece that was Kagome's but had been taken by Kikyo, who sometimes hangs out with him. He likes to go around as a white baboon and hires youkai with fragments to kill Inuyasha.

 

Evil Gas-when cut Naraku lets out this strong poisonous gas.

Spawns-after obtaining so many jewel shards he can create youkai from himself
