Magneto vs. non-omnipotents
Forgive me if my sources are incorrect.
Magneto vs. any non-omnipotent (e.g. Gods and God-like characters)
Is Magneto virtually unstoppable or at least equal to the strongest PSI's on Earth?
First assumption that I am going to make is that Magneto is at his full potential: Full control over magnetism! If you think about it from a physics point of view, he should be able to create lighting. All he has to do is to cause a lot of electrons to jump around.
If you think about humanoid physiology, the synapses are powered by electricity. So in that sense, he can make anyone brain dead. He put Bishop to sleep in AoA, I am sure he could've killed him.
So with this technique, wouldn't he be able to kill the Hulk?
So I think he's at least at as strong as any PSI's on Earth.
Why Magneto hasn't exhibited this strength is beyond me.
