King of Monsters

The path of the king of the monsters is one that should not lightly traveled, it is a path of war and destruction. There is only One Monster that can be called "The King of Monsters" the Unstoppable force of Godzilla! Barbarians can take on the path of the kaiju by completing a ritual by bathing in radiation. If the Entity that is The God of Destruction finds the Barbarian worthy they take on the aspect of Godzilla.
