His orphan upbringing is key. Growing up without parents, he lacked love and support, which might have contributed to his later evil nature. Also, his time at Hogwarts where he delved into dark magic. And of course, the discovery of his connection to Salazar Slytherin, which influenced his beliefs in pure - blood supremacy.
Tom Riddle, who became Voldemort, had a difficult start. His mother's family was related to Salazar Slytherin. In Hogwarts, he was sorted into Slytherin house. He started exploring the Chamber of Secrets, which was created by Slytherin. His thirst for power grew over the years. He split his soul into multiple Horcruxes in his quest for immortality. This act of dark magic made him more and more inhumane and led to his many evil deeds, like the murders of many witches and wizards.
One possible fanfiction could be where Harry uses a powerful, ancient magic that he discovers in a hidden chamber at Hogwarts. This magic has the power to reverse death, but he doesn't fully understand the consequences. So, when he brings Voldemort back, Voldemort is initially weak and Harry tries to keep him in check while learning more about this new situation.
I can't provide the full text of He Chao's novel 'Back' because I haven't read it. However, if you have any other questions about the novel, I will try my best to provide you with relevant information.
His personality would probably be more cold and calculating. Voldemort's influence would make him less empathetic. He might be more ruthless in achieving his goals.
Percy would likely become more cold - hearted. His loyalty to Voldemort would make him turn a blind eye to the harm being done to others. He might also become more power - hungry as he is influenced by Voldemort's thirst for domination.
Harry would likely become more cunning. He has to survive in Voldemort's lair, so he'd learn to hide his true feelings and intentions. For example, he might pretend to be more submissive than he really is to gain Voldemort's trust slightly.
Well, Voldemort's magic was mainly focused on dark and destructive spells. His son, on the other hand, could have a more balanced magic. Maybe he has an affinity for defensive spells as a way to distance himself from his father's aggressive magic. He might also have a unique ability to heal, which would be a direct contrast to Voldemort's harm - causing magic.
Well, if Harry finds out he is Voldemort's son in the fanfiction, it could mean a whole new set of powers for him. Maybe he has some latent dark magic abilities that start to surface. However, he would also have to deal with the stigma. Dumbledore's plans for him would probably go out the window. Harry might struggle to find his place between the light and the dark side of magic. He could try to use his newfound connection to Voldemort to defeat him in a different way, like by understanding his father's weaknesses from an insider's perspective.
