It is 6 o'clock in the morning and the sky is crying again. When my tears licked my skin like a needle, when I shivered and got mad, I stumbled and got up, but I was confused, I do not know where I am. The banyan tree rolled up in the light sky stands in the middle of this empty hell, and a sudden sudden attack makes me feel like I'm running. I ran out of the devil that took my innocence, but deeply, I knew they would find me. I shocked my pessimistic idea and attracted myself as much as possible.
The devil of the white eye is an ancient devil, Lilith is the oldest devil among the demons. According to the author, the power of their terrorism is very strong, they act as chiefs of various devils and are ranked highest at hell level. All the other devils seemed to be afraid of them, so they made their men angry. They are as strong as them, resisting the weakness of many devils. They can even fight normal angels. The only devils known for this type are Lilith and Alastair.
The only known yellow eye devil is Azazel. He is directly representative of Lucifer and he is leading a devil army belonging to him. He is the most powerful and powerful devil, manipulating various elements and controlling dreams. The only existing weapon that can kill him is Colt, holy water and other devil hunting tools are useless.
The devils did not kill or torture their own race to achieve their goals. For example, Tom tests fake Colt by shooting his devil "sister" Meg. Ruby, Crowley, and Meg killed themselves without pausing or regretting as their personal goals are for other devils. Advanced devils sacrifice their men without hesitation. At the same time, however, some devils established contact with their brothers and sisters. For example, Azazel called Meg and Tom a "child", and when Sam and Dean exiled Meg and killed Tom (a devil's trap) he was angry.
In the sixth season after Lucifer was restrained, most of the devil was under the command of Crawley, the king of the present hell. However, some devils like Meg opposed his rule. Through the sixth season, Crowley and his devil secretly helped Castiel find ways to open doors to purgatory to put the souls of millions of monsters inside. Although they succeeded, Castiel betrayed Crowley and absorbed all the souls for himself. During season 7, the devil was Leviathan's back seat and became the main opponent of the series. According to Crowley's order, the devil will not attack Winchester, so even though Winchester collided with the devil and repulsed Castiel, the boys can win the Leviathan.
