Who could be the main antagonist in 'Harry Potter turns into a veela fanfiction'?

Dumbledore could be the main antagonist. Harry might see Dumbledore as having used him all along for some grand plan. If Harry turns evil, he would want to break free from Dumbledore's influence. Dumbledore, with his power and wisdom, would then try to stop Harry from causing too much harm, thus becoming the main opposing force.

Maybe the Ministry of Magic could be the main antagonist. If Harry turns into a hybrid, the Ministry might see him as a dangerous abomination. They could try to capture him and keep him locked away, thinking that his new form is a threat to the wizarding world's order. They might not understand that Harry is still the same person inside and that his new form could actually be an asset in the fight against evil.

It could still be Voldemort. Even if Harry is turning to the darkside, Voldemort might see him as a threat because Harry has his own unique power. Voldemort might not want to share his control over the dark forces with Harry, so he would become the main antagonist in a fight for dominance in the dark world.

Umbridge could also be a main antagonist. She is known for her strict and often cruel rules. If she discovers Harry in his female animal form, she would likely try to use it as an excuse to further oppress him. She might see it as a sign of abnormal magic and use it to justify her actions against Harry and those she doesn't like in Hogwarts.

It could be a powerful vampire clan that doesn't want Harry, a new vampire, to disrupt their ways. They might try to either kill him or force him to join their ranks against his will. They could see him as an outsider who doesn't belong in the vampire world and a potential danger to their secrecy.

It could be Dumbledore. If Harry turns to the Dark Side, Dumbledore, who has always been a guiding figure for Harry, would be the main one to oppose him. Dumbledore represents the light and everything Harry is now against. Dumbledore would try to stop Harry from causing chaos and destruction in the wizarding world.

Perhaps a long - lost relative of the Potter family who feels they were unjustly excluded from inheriting the manor. This relative could be jealous of Harry's status and the wealth associated with the manor. They might use dark magic to try and claim what they think is rightfully theirs, leading to a battle of magic and loyalty within the Potter family and among Harry's friends.

It could be the pure - blood supremacists. They might see the relationship between Harry, a well - known wizard, and the Veela Queen as an abomination because they believe in the purity of wizard blood and would not accept a union with a non - wizard being like the Veela.

Another possibility is that it's a character related to the Veela community. A Veela elder or a young Veela who is chosen for this special training. This character would bring the unique Veela culture and magic into the story, and their interactions with the wizarding world outside of the Veela community would be an interesting aspect of the fanfiction.

Maybe there could be a new antagonist, a dark shapeshifter who is jealous of Harry's power. This antagonist could be an old wizard who has been in hiding for centuries, waiting for the right time to emerge and take over the wizarding world. He sees Harry as a threat to his plans and tries to eliminate him.
