Well, it could be an original character who was hidden away from Magneto for some reason. Maybe a human - mutant hybrid that Magneto didn't know about. This son could have powers that are not fully developed at first, and through his encounter with Magneto, he starts to discover and master his abilities. He could be a character who was raised by a family that was against Magneto's ideas, so there's a lot of conflict when they meet.
I really like 'Magneto's Ascent'. In this fanfic, Magneto's rise to power is depicted in a very detailed way. The author does an excellent job of building the world around him, his relationships with other mutants, and the political landscape that he has to navigate. It's full of action and great dialogue.
Well, it's quite possible. Fanfiction writers love to blend different universes and characters. A 'Naruto is Magneto' fanfiction could explore how Naruto, with Magneto - like powers, would change the Naruto universe. He could use magnetic abilities in battles, perhaps controlling weapons in a new way or even interacting with the natural elements in the Naruto world differently. To find such a fanfiction, start by looking through the relevant categories on major fanfic sites.
The story where Magneto teams up with the X - Men against a common enemy like Apocalypse is also a great Magneto story. In this story, Magneto has to put aside his differences with the X - Men for the greater good. He uses his incredible magnetic powers to help in the battle. It shows that despite his often - antagonist role, he can be a hero when the situation demands it.
One of the best Magneto stories is his origin story. It shows how his experiences as a Holocaust survivor shaped his views and his powers. His early days of realizing his mutant abilities and the discrimination he faced were crucial in making him into the complex character he is. He was constantly fighting against a world that feared and hated mutants, which led to his more extreme stances at times.
A good Magneto fanfic often has a deep understanding of his character. It should capture his complex personality, his anger towards humanity for the mistreatment of mutants, and his drive to protect his own kind. For example, if it shows his internal struggle between his desire for revenge and his hope for co - existence, it can be really engaging.
