Chaotic Gore Magala

The natural life cycle of a Gore Magala eventually leads them to transforming into the Elder Dragon Shagaru Magala. However, some unfortunate individuals fail to complete the transformation and are stuck halfway between forms and become a Chaotic Gore Magala, entities writhing in agony that are unable to control the immense power of an Elder Dragon, making them lash out at anything they come across until they're finally put out of their misery.
