XM #46] How did Magneto arrive amnesiac in South America, and how was he de-aged?
Mystery: A man looking just like a young Magneto found himself contemplating his past in a tomato field in South America. He had vague memories of being different and living among the stars. Also, he remembered a violent crashing towards Earth, and being with a man of metal. However, he had no clue who he was or what he was doing in South America. Resolution: Joseph, as this amnesiac stranger would later be called, joined the X-Men eventually under the belief that he was an amnesiac and de-aged Magneto. However, in X-Men (2nd series) #72-73 it became clear that Joseph was not Magneto at all, and he left the team with the mutant known as Sabra to figure out the truth. During the Magneto War crossover, Joseph discovered that he was an exact genetic clone of Magneto, created by a woman named Astra, who sought revenge against Magneto for a past offense. To give him more raw power, she made the clone younger than Magneto and sent him after Magneto, while attending to other matters herself.
