Gouki is an Upper E Class demon and part of Hiei's underworld gang, known for being a soul-eating ogre. His humanoid appearance is imposing—a tall guy with prominent horns running across his forehead. When he shifts to his true demon form, things get way more monstrous: his horns grow massive, and his fangs and eyes enlarge dramatically.
He's best known for his fight with Yusuke, who managed to take him down with a powered-up Reigun blast straight to the mouth. After that loss, Gouki gets arrested. Fans often note that despite his intimidating build and demonic nature, he went down surprisingly fast once Yusuke really powered up.
