The Harry Potter series is known for its well-developed characters, including a variety of protagonists and antagonists. The main antagonist throughout the series is Lord Voldemort, also known as "He Who Must Not Be Named" and "The Dark Lord." He is a powerful dark wizard who seeks to dominate the wizarding world and destroy anyone who stands in his way, including Harry Potter.
Voldemort is not the only antagonist in the series, however. There are many other characters who serve as obstacles for Harry and his friends as they try to defeat Voldemort and save the wizarding world. Some of these characters include:
Bellatrix Lestrange: She is a loyal follower of Voldemort and a member of the Death Eaters, a group of dark wizards who serve Voldemort. She is cruel, sadistic, and ruthless, and she enjoys causing pain and suffering to others.
Severus Snape: He is a complex character who serves as a double agent, working for both Dumbledore and Voldemort. He is often seen as a bitter, sarcastic, and cold-hearted person, but he ultimately plays a crucial role in helping Harry defeat Voldemort.
Lucius Malfoy: He is a wealthy, influential wizard who is a member of the Death Eaters and a father to Draco Malfoy. He is cold, calculating, and manipulative, and he often uses his wealth and power to try and get what he wants.
Draco Malfoy: He is a classmate of Harry's and the son of Lucius Malfoy. He is arrogant, insecure, and often bullies others, particularly Harry and his friends.
Dolores Umbridge: She is a high-ranking official in the Ministry of Magic and a loyal follower of Voldemort. She is strict, authoritarian, and sadistic, and she enjoys using her power to punish and control others.
These characters, along with many others, serve as obstacles and challenges for Harry and his friends as they try to defeat Voldemort and save the wizarding world. While each character has their own motivations and methods, they all share a common goal of standing in the way of Harry and his friends and supporting Voldemort's efforts to dominate the wizarding world.
