Who could be the main antagonists in 'Harry Potter master of wandless magic fanfiction'?

Obviously, Harry Potter is a main character as the title suggests. He is the one who is on the journey of learning wandless magic. Hermione Granger could also be an important character. She might be helping Harry research about wandless magic, using her vast knowledge from the library.

The pure - blood supremacists could be the main antagonists. They might oppose Harry's ideas of a more inclusive and democratic political system as they believe in the superiority of pure - blood wizards.

It could be the Death Eaters who see Harry's new - found mastery of darkness as a threat to their own power and ideology. They might try to either recruit him or destroy him. Voldemort himself could be an antagonist, feeling that Harry is encroaching on his territory as the most powerful dark wizard.

Obviously, Voldemort could still be the main antagonist. He would be intrigued and threatened by Harry's new power, the lightsaber. Also, some Death Eaters might team up with dark wizards from other lands who are also after the power of the lightsaber.

Well, Harry Potter masters wandless magic by having intense mental focus and a deep understanding of magical theory. He also gets guidance from some mysterious mentors and has many challenging experiences that force him to develop this ability.

The Death Eaters could still be the main antagonists. Even though Harry has this new connection to Lady Magic, the Death Eaters, loyal to Voldemort, would see him as a major threat to their dark plans and would continue to try to kill him.

The Death Eaters could still be the main antagonists. If Harry starts learning soul magic, they might see it as a threat and try to stop him.

There could be a powerful dark entity that has been awakened by Harry Potter's newfound mastery of fire and darkness. This entity could be an ancient evil that was once sealed away and now wants to use Harry for its own dark purposes or simply destroy him as he is a potential obstacle.

One interesting plotline could be Harry discovering ancient wandless magic spells hidden in the Forbidden Forest. Maybe he stumbles upon a long - forgotten magical grove where the magic is so pure that it doesn't require a wand. He then has to learn how to control this new - found power without the guidance of his usual wand - based magic training.

In some fanfictions, Harry Potter might develop his wandless magic skills through intense mental training. He could practice focusing his magic without the aid of a wand, much like how he learned to control his Patronus. By visualizing the desired outcome clearly in his mind and concentrating his magical energy, he gradually becomes proficient at wandless magic.
