Goki was an impressive villain for the very first few episodes, but I hated the guy with a passion.
He was one of the trio of demons who stole three powerful items from Spirit World.
His true form was like a demonic ogre, and he almost kills Yusuke before being spooked by Botan who was pretending to be a mob of angry villagers.
The orb he stole would allow him to steal the souls of anyone he wanted.
Which he would consume like food.
He was shocked that Yusuke came back to challenge him. But with souls on the line, he wasn’t going to wait.
And Yusuke kills him with a spirit gun blast to the mouth.
Ironically, he was the only demon of the trio to die. I kind of wonder what it would’ve been like if he had joined the team like Kurama and Hiei.
