Well, if Harry Potter was raised by Terminators in fanfiction, it could lead to some really interesting crossovers. For one, his magic could be combined with the Terminators' technology in unique ways. Maybe he'd use magic to enhance the Terminators' capabilities or use their technology to boost his own magical feats. Also, his view of good and evil might be more black - and - white like the Terminators, instead of the more nuanced view in the wizarding world.
In a 'Harry Potter raised by Terminators' fanfiction, the story could take many turns. Harry would likely have a very strict upbringing, with the Terminators' focus on mission and efficiency. His relationships would be different too. Instead of having close friends like Ron and Hermione from the start, he might be more solitary, used to following orders from the Terminators. His understanding of the world would be a blend of the wizarding world's magic and the Terminators' view of a post - apocalyptic future. He could potentially use his magic to prevent the dark future that the Terminators are often fighting against, or he could bring a new form of power to the fight against Voldemort that the Death Eaters would never expect.
