Lucifer

Lucifer is a secondary character of My Best Friend Marneao. He's husband of Samantha, father of Marneao and king of Inferni. He was the best friend of the first god, Yahveh, during the Old Heaven's times.

Appearance
Lucifer is a red demon old man, with a tail and horns. He has black hair, bags under his eyes, a round nose and short beard. He's usually wearing a full black suit, with a dark brown shirt under it and a black tie.

Personality
Lucifer is usually a kind person. He loved his wife and loves his son as well as all the humans and demons under his command. He's good at creating plans. Under stress, he becomes quite irritable and tends to yell at people.

Abilities
The full length of his abilities are unknown but he can create life (in the case of demons). He also can use dark energy as an attack. Same as most demons, he has super strength, super speed, high resistance and is able to fly.

He also has the ability to mind control, and rewrite memories.

Before Old Heaven
It is not clear what Lucifer and Yahveh did before arriving to Old Heaven. Traveling through dimensions, they arrived to a place where they saw a strange creature arriving out of nowhere. Little did they know that creature would soon change their lives forever.

Old Heaven
When the amount of creatures, later being recognized as "humans" increased dramatically, they created an ever-expanding kingdom to take care of them, creating a peaceful society around with demons who would do hard work and Angels that would defend humans from the ocasional creature that would appear around the kingdom. The amount of residents would soon create a need for energy and resources. Lucifer and Yahveh would struggle to solve this problem until Ariel, an inventor angel, suggested creating windmills. However, a human inventor called Kristoff would later arrive with a perpetual energy device that would make the kings forget about the windmills. This would derive into a terrible attack by the hands of Ariel's sons Miguel and Baraquiel that destroyed half kingdom killing hundreds of thousands of people. After Miguel kills Yahveh, Lucifer is forced to live in a cave with the survivors.

Jacob's contract
Many centuries after Inferni creation, Lucifer's son, Marneao would accept a contract of a human kid who wanted a best friend. This would increase the tension between Inferni and Heaven that would explode after Gabriel, the shield of heaven, died in the hands of the revolution. Baraquiel would soon order Lucifer to kill the human kid and bring by force his son, thing that Lucifer would not accept. He would die in the hands of the Angel.

Etimology
Lucifer's name in Enochian is written:

Production Notes
Lucifer was created pretty much looking like Marneao, but older. His personality has nothing to do with the biblical version. I think of this Lucifer more like some alien creature, maybe lovecraftnian. A sentient being capable of creating life traveling with his friend, another creature of similar kind, through time and space.

It is until season 2 that we are able to know more about him. His wife, his son, his best friend, and his relationship with Yahveh kinda mirrors Marneao's with Jacob and see him fight for real.
