It really depends on how the fanfiction is written. If it follows the traditional power levels, Sonic with his super speed and ability to transform into Super Sonic could be very powerful. He has proven time and again to be able to take on strong foes.
Well, one possibility could be that Sonic and Eggman are forced to team up against Black Doom. Maybe Black Doom is threatening to destroy their world, and they realize that only by combining their strengths, Sonic's speed and Eggman's technology, can they stand a chance.
Well, it depends on the specific plot of the fanfiction. Maybe Birdie would try to avenge Jasmine's hurt, or Doom could be the one who caused it and face consequences. Without more details, it's hard to say exactly.
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.
The top magneto stories can also include its use in magnetic levitation (maglev) trains. These trains use powerful magnets to float above the tracks, reducing friction and enabling high - speed travel. It's a revolutionary way of transportation. Additionally, the study of magneto in particle accelerators is also quite interesting. Scientists use magnetic fields to control and accelerate particles, which helps in understanding fundamental particles and the laws of physics.
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.
