"The Wonder of the Ages!!! Magneto!"
Hunk Larkin is the biggest, strongest man in the county, even if he isn't the smartest. He can't hold a job, so he eventually becomes the fodder for the dangerous job of first manned space mission. His rocket passes through a band of radiation and he returns to Earth with the power of magnetism. Hunk decides to use his new powers to get even with mankind for its cruelty, and he is soon dubbed Magneto (Magnetor in reprints). He is ultimately tricked onto a space ship headed for the stars, for his good and ours. 13 pages.
Note: this story formed the prototype not only for Magneto, the first evil mutant, but the origin story was re-used in the birth of the Fantastic Four.
Reprinted in Monsters on the Prowl #24, retitled "The Wonder of the World!!! Magnetor!"
"They Met on Mars!"
Two ships land nearly simultaneously on Mars, both eager to claim the planet as theirs. The two odd looking pilots step out of their ships and face each other. One flees to his ship and departs, but not before destroying the other's ship. Both, it turns out, were human, wearing other-worldly space suits. 5 pages.
