It's the Complete Monster thread. It was a recent description; search up something along the lines of "Ultimate Magneto Complete Monster Cleanup" on Tropes' primary search bar and it should net you the result. If not, I can just say that one of the primary contributers of the thread noticed that Ultimate Magneto ultimately showed some regret for ravaging the world, just enough to bump him off from the trope.
