Amelia Bones might confront the abusers directly. If it's the Dursleys, she would give them a stern warning or even use magic to make sure they can't harm Harry anymore. She could also arrange for Harry to have proper magical education away from the negative environment he was in, so he can grow and develop his skills without fear.
She might be shocked and immediately take steps to protect Harry. For example, she could remove Harry from the abusive situation and place him in a safe environment, like her own home or a place under the protection of the Ministry where he can't be reached by his abusers.
She is often portrayed as a strong and capable witch. She's shown to be fearless in the face of danger, especially when it comes to dealing with dark magic and dark wizards.
There might be. Fanfiction is a place where creativity knows no bounds. Writers might have thought that having Amelia Bones as Harry's godmother could add an interesting dynamic to the story. Maybe she could protect Harry in ways that others couldn't, or perhaps there could be a whole new backstory involving her relationship with James and Lily. It could also lead to different plot developments in the face of Voldemort's threat.
Amelia Bones is a high - ranking official in the Ministry. She is part of the wizarding establishment that Harry Potter often has to interact with. Her role could be crucial in times of upheaval, like during the return of Voldemort. She might offer her expertise or resources to Harry and his friends in their fight against the Dark Lord.
One common theme is mystery. Since Amelia Bones was involved in investigations in the wizarding world, fanfictions often use her to uncover secrets related to Harry Potter or the overall wizarding world situation. Another theme is mentorship, as I mentioned before, where she imparts her knowledge to Harry.
There isn't really one 'best' author as different readers have different tastes. However, some authors who have a large following for their 'Harry Potter' fanfictions might also do a great job with Amelia Bones. They usually have a good understanding of the overall 'Harry Potter' universe and can integrate Amelia Bones into the story in a seamless way. You might want to look for authors who have received a lot of positive reviews for their stories involving similar themes or characters.
A common plotline is Amelia Bones protecting Harry from the Ministry's unjust actions. Since the Ministry is often shown as corrupt or misinformed in some fanfics, she steps in to ensure Harry's safety.
One possibility is that they meet during a Ministry event. Harry is there because of his status as the 'Boy Who Lived' and Amelia Bones is representing the Department of Magical Law Enforcement. They strike up a conversation about the future of the wizarding world and how to better protect it from the remnants of Voldemort's followers.
