Kibutuji Muzan

Kibutsuji Muzan (鬼舞辻 無惨) Demon, 1000+ years old, Demon King but afraid of Yoriichi , 179 cm, 75 kg, December 28 birthday. His backstory↓ He was human but was close to death due to a random illness. But a doctor gave him such a fake 'medicine' that he turned into a demon (what the hell????) After she transformed, but it didn't matter. Then she killed the doctor, but that was a really stupid idea because the doctor didn't finish the treatment. That's why he remained forever weak to sunlight (I think he deserved it a little if he was so stupid as not to think of this). For centuries, he tried to find a way to be in the sunlight, so he created demons, hoping that at least one of his demons would be able to do it. Abilities: Almost immortal, regenerates after 2 seconds. Can transfer demonic blood, which creates new demons. Can shape his body at will (for example, into a woman, a child, or a monster). Special Technique: Biological Manipulation (can create multiple hearts and brains within himself to think and fight faster= ufo) Enhanced senses, speed, and strength. Personality: Extremely selfish and cruel, sees others as tools. Expects complete obedience from his subordinates. Fearsome and cold, he does not tolerate opposition. He hates weakness and will kill his own demons if they fail. Fate: Muzan eventually clashes with the Demon Slayer squad and after a long fight, loses humanity's last hope of resisting sunlight, with the help of Nezuko. Kamado Tanjirou gains Muzan's demonic power in a final attempt, but ultimately manages to defeat the Demon King and end his reign forever. (But afterwards Tanjirou will become the Demon King because he will get his power and become a demon)
