Baeklang

The Legendary Beast Heuklang's shiny, ebony fur turns white, and it only acts instinctively and destroys all before its eyes. In this state, it is referred to as Baeklang.

One Heuklang turned into Baeklang with its heart filled with darkness, after being attacked by the forces at the Centipede Market, who were trying to dispose of all that was not human.
