In anime, the demon lord often serves as a powerful antagonist, controlling other demons or dark forces threatening to engulf the world. This role carries significant responsibility and power, frequently leading to conflicts with heroes or other formidable entities. The strength of a demon lord often acts as a crucial plot point, influencing the very structure of the universe around them.
We must commend the demon lords in anime, as without them, the main characters would lack the powerful adversaries needed for compelling stories.
Demon lords not only represent strength but also challenge the moral standards within anime, often serving as primary goals for many main characters.
Of course, there are instances where demon lords are portrayed as charming characters, easily becoming a favorite for the audience despite their evil nature. The role of a demon lord can shift from being a mere villain to a complex character navigating through various conflicts, including battles against heroes or oppressive rulers vying for control in a world filled with magical power. This archetype has proven to be both interesting and successful, indicating that the allure of demon lords continues to grow over time.

He possesses incredible powers that allow him to manipulate almost all forms of physical matter and, like a true demon lord, can dominate anyone. He has a unique ability that allows him to control gravity, alongside a magical strength so immense that it could potentially obliterate the living world if released.

Satan is a demon lord whose existence has successfully conquered and annihilated the living world. Satan from Devilman Crybaby is capable of achieving his goals through a dark plan devised beforehand, with a goal being to release a demon army to exterminate humanity, akin to the way insects might inhabit life on Earth.
Satan not only possesses formidable physical abilities but can also create chaos on Earth, transforming his surroundings into blood and using the very essence of humanity in a horrific and cannibalistic manner.
