It's fairly common for heroes covered here to not have any form of civilian identity, with some going as far as not even giving us a name for these characters outside of their superhero persona. This isn't done to be mysterious or anything, they just don't care - they're just throwing heroes at the wall hoping one of them sticks... but they don't tend to. Except Magno.
Meet Magno, Master of Magnet. That's his main power - he can use the powers of magnetism to fly around, control various metal objects and, like all good heroes, beat up Nazis. Basically, he's Magneto, but if he were one of the good guys. Despite Magno not even bothering to wear a mask, he's surprisingly difficult to trace to any civilian identity. Maybe he doesn't even have a life, maybe he's just Magno 24/7. Curiously, his boy sidekick took the opposite approach, going by his real-life name "Davey Landis" in lieu of a superhero name.
Unlike many heroes covered here, Magno actually had a recurring Rogues Gallery, including esteemed members such as Cobra (who just naturally had fangs and so dresses up as a snake and fights Nazis) and The Clown (not to be confused with the cop-turned-clown hero I've covered previously).
Another surprise is just how long this guy lasted. 34 issues of Super-Mystery Comics, and 26 of Four Favourites, that is a long run for one of these people - especially one who doesn't have any form of civilian identity. It's no surprise then that he has also been reused in modern days, though so far he's mainly been relegated to a minor appearance in Project Superpowers.
