Hunwoo

Hunwoo (aka Snoop) was a goblin in Swearword gang. He managed to save Gwangnam from being eternally destroyed by Pajuju before the Four-Dong leaders arrived.

In gratitude to Gwangnam for saving the rest of the goblins, Hunwoo broke off his own goblin horns so that he's no longer bound to goblin laws in order to leave Middle Town with Hodong to warn Gwangnam of his fated eternal destruction at the Death World equivalent of Jaehwa's home.
