Another plotline might involve Harry adapting to Bellatrix's rather extreme and unorthodox parenting style. He could be learning dark magic in a way that still aligns with his own sense of good, which would create a lot of internal conflict for him. Bellatrix, on the other hand, might start to have a change of heart as she sees Harry's positive influence on her in some aspects.
A possible plotline could be the reactions of the Order of the Phoenix and the Death Eaters. The Order would be horrified to find out that Harry is with Bellatrix, and they would try to rescue him. Meanwhile, the Death Eaters would be suspicious of Bellatrix's motives and might try to undermine her while she is protecting Harry.
Well, in some of these fanfictions, the plot could involve Harry having to adapt to a completely different world from the wizarding one. Gibbs would be like a father figure, guiding him through the Muggle world's rules and values. There could also be a plot where Harry's past with Voldemort makes him a target in the Muggle world, and Gibbs has to protect him while also trying to understand this whole new concept of magic.
Well, in some 'Draco Adopts Harry' fanfictions, a great plotline is how Draco overcomes his past enmity towards Harry. He starts to see Harry as a person in need rather than an enemy. There could be a plot where they work together to uncover secrets about Harry's past that Dumbledore might have hidden. And then, Draco has to protect Harry from those who don't want the truth to come out.
One possible plotline could be Harry seeing the potential for good in Tom even though he knows of Voldemort's future. He might try to raise Tom with love and kindness to change his path. For example, Harry could introduce Tom to the wizarding world in a more positive light, showing him the beauty of magic for good rather than for power.
One possible plotline could be Minerva helping Harry discover his true magical potential outside of just the Boy - Who - Lived status. Maybe she teaches him advanced magic that Dumbledore didn't have time for. Another could be Minerva protecting Harry from the darker elements in the wizarding world, like the Death Eaters, in a more motherly way. She might also introduce him to different magical cultures that he was previously unaware of.
A great plotline might be that Snape adopts Harry secretly at first. Harry starts to notice some changes in his life, like getting better study materials and more personal attention in his magical education. As time goes on, Snape has to face his own demons while raising Harry. He might struggle with his past hatred for James Potter while seeing James in Harry. At the same time, Harry could be trying to figure out why Snape is being so nice to him all of a sudden, which could lead to a journey of self - discovery for both of them.
One possible plotline could be that Harry uses a powerful spell he's been secretly practicing to stun Bellatrix just in time as she's about to harm Hermione. For example, he might use a modified version of the Stupefy spell that's more powerful. Another could be that Harry manages to create a diversion, like summoning a horde of magical creatures, which distracts Bellatrix long enough for him to rescue Hermione.
One possible plotline could be Bellatrix having to protect the members of her harem within the dangerous wizarding world. Maybe they face threats from Voldemort's other followers who don't approve of her 'harem'.
In some fanfictions, Minerva adopts Harry after realizing the Dursleys are mistreating him. She then takes on the role of a mother figure, which is a huge change for Harry. This could include her taking him shopping for new robes and school supplies in a more loving and nurturing way than the Dursleys ever did. She might also introduce him to the wizarding world in a more personal and gentle way, making him feel truly welcome.
One common plotline is redemption. Bellatrix might start to question her loyalty to Voldemort when she realizes her connection with Harry. Another is a battle of wills that turns into love. They initially fight against their soulmate bond but eventually give in.
A possible plotline is that Snape's adoption of Harry causes a rift in the wizarding community. Some might support it, seeing it as a way to keep Harry safe and under the watchful eye of a powerful wizard. Others might oppose it, fearing that Snape's dark past could influence Harry negatively. This conflict could lead to many adventures and challenges for both Snape and Harry as they try to navigate through the political and social turmoil.
