The dark male protagonist usually referred to a character's personality, psychology, and behavior gradually becoming cold, cruel, violent, and dark after experiencing a certain event or encounter. These changes usually occur during the growth of the character. They may be influenced by the external environment or may be caused by the character's own inner struggle. In novels, there was usually a relatively long process in the process of the blackened male protagonist's training. The character experienced a series of setbacks and hardships, suffered all kinds of abuse and torture, and finally gradually grew into a stronger character through continuous self-torture and self-redemption. In the process of training the Dark Male Lead, the character might become selfish, cold, heartless, and sometimes even lose his humanity. But at the same time, he might also become more determined, decisive, brave, and aggressive to fight against external enemies and internal self. In the end, the blackened male protagonist would usually become a more mature and powerful character, and at the same time, it might bring more profound thinking and reflection.
