Harry's character can be developed by showing his curiosity. When he first encounters the concept of'monster girls', he could be intrigued and start asking questions. This shows his inquisitive nature which is a big part of his character in the original series. For example, he might ask about their magic that is different from what he knows at Hogwarts.
One idea could be that Harry discovers a hidden part of the wizarding world where there are 'monster girls'. Maybe he stumbles upon a secret club at Hogwarts. Through his interactions with them, he learns about their unique cultures and magic. This could lead to him wanting to be more involved with their world, perhaps even using his skills to help them with problems they face.
In a 'Harry Potter as a Necromancer' fanfiction, Harry's development could involve him learning from his mistakes. For example, if he accidentally creates a dangerous undead creature, he realizes the importance of control. He could also become more empathetic towards dark wizards who might have been drawn to necromancy for reasons like his own. His relationships with his friends would change too. Some might distance themselves, while others would try to understand and help him. This would force Harry to grow and become more self - reliant in his journey with necromancy.
If Harry wears armor, it could make him seem more like a knight. His sense of chivalry could be enhanced. He might be more confident in battles, which could lead to him taking more risks. This would show his growth as a character, as he becomes bolder in the face of danger.
Often, his character is developed by exploring his backstory. Writers might give details about his family, his upbringing, and what led him to create or obtain the Deathly Hallows. This helps to build a more complex and three - dimensional character.
You can also show her doubts. Even though she was a loyal Death Eater, there could be moments where she questioned Voldemort's methods or decisions. This would make her more human and less of a one - dimensional villain.
She could start as a somewhat shy and reserved character, still trying to find her place in the wizarding world. But as she discovers the Mew Mew Power, she becomes more confident. For example, she might start standing up to bullies like Draco Malfoy more often. The Mew Mew Power gives her a sense of purpose and a new identity within Hogwarts.
His magical abilities also play a crucial role in character development. If he has a special talent for some form of magic, like being able to communicate with magical animals in a way no one else can, it can lead to interesting storylines. He could use this ability to help solve problems or get into trouble. Through these situations, his character can grow, learn from his mistakes, and become a more well - rounded character in the fanfiction.
In addition to the above, the theme of mystery often comes up. The origin of the monster girl and her connection to the wider magical world can be a big mystery. Some fanfictions explore how her presence might be related to ancient magic or forgotten prophecies in the Harry Potter universe. Also, the theme of growth is present as she learns and matures within the Hogwarts environment, facing both academic and social challenges.
Perhaps Harry has a vision or a prophetic dream where he sees himself as a healer, saving lives. This drives him to study hard in his Healing classes at Hogwarts. He also starts to research ancient healing techniques on his own. He faces some challenges, like some people doubting his ability because of his past as 'the boy who lived', but he overcomes them and works towards his goal.
Jasper can be developed by having her adapt to the unique culture of Hogwarts. For instance, she could struggle with the house system at first, not understanding why students are so divided. But as she spends more time with Harry Potter, she learns to appreciate it and even finds her own place within it. This would show her growth and integration into his world.
