One way is through his connections. Draco has ties to the wizarding world's dark side, which means he could potentially get inside information on the Horcruxes. He might use his family's influence or old Death Eater contacts to dig up secrets.
Another aspect is his change of heart. If in the fanfiction Draco has a change of heart about Voldemort and his ways, he could actively join the Horcrux hunt. He might use his skills in stealth and subterfuge, which he learned from his time as a Death Eater - in - training, to spy on other Death Eaters and find out if they know anything about the Horcruxes.
One way is by using his Slytherin cunning. Draco is known for his intelligence in a sly way. He could outwit the cave's defenses. He might be able to figure out puzzles or riddles that are protecting the Horcrux. His quick thinking could be a great asset.
In some fanfictions, Draco might use his knowledge of the Dark Arts and Hogwarts' secrets. Since he was raised in a Death Eater family, he could have insights into how Voldemort might have hidden the Horcruxes. For example, he might know of certain places within the school that Voldemort frequented or had an interest in.
Hermione might be one of his allies. Despite their past differences, they could put aside their grudges for the greater good of the Horcrux hunt. Also, Neville could potentially be an ally. Neville has shown great courage and determination, and he might see Draco's newfound willingness to fight against Voldemort as a sign of change.
In some fanfictions, Draco might use his knowledge of the Dark Arts. He could have insights into the protections around the cave that Voldemort might have set up, given his family's closeness to the Dark Lord. For example, he might know about certain spells or enchantments that are typical of Dark magic and be able to help the characters navigate through them.
One possible plot twist could be that Draco has a hidden agenda all along. Maybe he's actually trying to protect a particular Horcrux for his own reasons. Another could be that he discovers a new Horcrux that no one else knew about, throwing the whole hunt into chaos.
One way is as a mentor. He could pass on his old - fashioned spells and incantations to the young wizards in the story. Another way is by using his foresight. If he has the ability to see into the future, he could warn Harry about upcoming threats or traps. For instance, he could foresee Voldemort's next move and tell Harry how to counter it.
Another plot could involve Draco actually knowing some secrets about the Horcruxes that he initially doesn't want to share with Harry. But as the danger of Voldemort's power growing becomes more and more real, he realizes he has to help. So, during the hunt, Draco gradually reveals bits of information that he has, which helps Harry in unexpected ways. This could lead to a redemption arc for Draco, as he goes from being on the side of the Death Eaters in a way to actively working against Voldemort by assisting Harry.
Their relationship could start with hostility. Draco has been an enemy to Harry for a long time. But during the Horcrux hunt, they might find common ground. For instance, they both want to stop Voldemort, even if their reasons are different. This common goal could lead to a grudging respect. Harry might see that Draco isn't all bad, and Draco might see Harry as more than just the 'Chosen One' he resented.
Kurenai can be helpful in Naruto fanfiction in terms of character development. For example, if there's a character who is shy or lacks confidence, kurenai can take them under her wing and help them grow. Also, in battle - related scenarios, her strategic mind can be a great asset. She can plan out attacks and defenses that other characters might not think of. Moreover, her connection to the other ninja in Konoha can be used to create more complex and intertwined storylines in the fanfiction.
One way is through the characters' dialogues. They might talk about their sexual desires, experiences, or taboos, which gives the reader an idea about how sex is perceived in the world of the novel. For instance, in a coming - of - age novel, the protagonist may discuss their first sexual encounter with a friend, revealing their fears and excitement.
