Goz (ゴズ, Gozu) is a big oni (ogre) that is in charge of Hell together with Mez. King Yemma is his boss and also the only oni who is stronger than Goz. His skin is blue, he has purple hair and one horn. He stops Goku from eating Ensenji (King Yemma's Fruit) by hitting him with a spiked club, challenges him to wrestling match and toys with him for some time, pretending to help him leave Hell.
The voice of Goz in Funimation dub is provided by Christopher Rager. In original Japanese, Goz speaks with adding おに ("oni") to the end of each sentence.
