One possible antagonist could be a new, dark wizard who has a vendetta against Gryffindor house. Since Katie Bell and Harry Potter are both Gryffindors, they would be prime targets. Also, there could be a power - hungry Slytherin student who wants to undermine their influence in the school and tries to set them up for various misdeeds.
The Slytherin Quidditch team could be antagonists in a way. If Katie Bell and Harry Potter are on the Gryffindor Quidditch team, there could be rivalries that turn nasty. And, of course, Voldemort's remaining followers who are still causing chaos in the wizarding world might see Katie Bell as a way to get to Harry Potter, making them antagonists in the fanfiction.
Draco Malfoy could be an antagonist. He might be jealous of Katie Bell's friendship with Harry Potter and try to cause trouble for them. Another potential antagonist could be a Death Eater who is still at large and targets Katie Bell to get to Harry Potter.
Yes, there might be some. Fanfiction platforms often have a wide variety of creative stories. You can try searching on popular fanfiction websites like FanFiction.net or Archive of Our Own. Just be aware that the quality and nature of these stories can vary greatly.
The pure - blood supremacists could be antagonists. They might not like the idea of Harry, a half - blood, inheriting Hogwarts and try to undermine his authority.
Maybe there could be a group of rogue wizards who believe that Harry's power to be the master of life is an abomination against the natural order of magic. They would oppose him and try to strip him of his power, seeing themselves as the protectors of the 'true' way of magic. Another potential antagonist could be a power - hungry wizard within the Ministry of Magic who is jealous of Harry's new - found abilities and tries to undermine him at every turn.
Voldemort's remaining followers could be antagonists. They might see the baby as a new threat or a potential weapon. They could try to kidnap the baby to use its power for their own dark purposes.
One common theme is the 'forbidden love' aspect. Since Harry is often in the spotlight and has a lot of responsibilities, a relationship with Katie might be seen as something that has to be kept quiet. Another theme is the idea of healing. Katie Bell was a victim of the Dark Arts, and in some fanfics, her relationship with Harry helps her heal from that trauma while also helping Harry deal with his own emotional baggage.
Yes, there are quite a few out there. You can start by looking on fanfiction platforms like FanFiction.net or Archive of Our Own. Just search for 'Harry Potter and Katie Bell Romance' and you'll likely find some interesting reads. Some might focus on their relationship developing during their Hogwarts years, while others could explore what might have happened after they graduated.
One possible plot could be that Katie Bell was in a relationship with an original character. She gets pregnant and has to deal with the challenges of being a young mother in the wizarding world. She might face judgment from the wizarding society and have to find ways to support herself and her baby.
One potential antagonist could be some pure - blood supremacists who don't like the idea of Harry Potter having a half - blood or Muggle - born daughter. They might try to cause trouble for Lemon at Hogwarts or in the wizarding world in general. Another could be a dark wizard who sees Lemon as a threat for some reason, perhaps because of her special abilities or her connection to Harry. They would try to harm her to get to Harry.
Voldemort could still be an antagonist. He might see Harry as an even greater threat now that he has the connection to Laughing Jack. He could be afraid that Harry's new powers will be used against him.
No, they are not. Canon refers to the official and original storyline as created by J.K. Rowling. Lemon fanfictions are fan - created works that often involve non - canon relationships and scenarios, especially when it comes to the more mature content like in 'Harry Potter and Katie Bell' lemon fanfictions.
