In Marvel Superheroes Secret Wars, Magneto takes time between the fighting to romance the Wasp. She reciprocates his desires, but then turns on him.
Many bizarre romantic trysts have happened in comics, and one that’s hardly ever mentioned is the time X-Men antagonist Magneto decided to hook up with founding Avenger the Wasp. While the pairing has mostly been forgotten, the story it comes from isn’t obscure. It takes place in the third and fourth issues of one of Marvel’s first major crossover events, Marvel Superheroes Secret Wars (1985), by Jim Shooter, Mike Zeck, and Bob Layton.
The classic saga features many Marvel heroes and villains being abducted and forced to fight each other by an ancient otherworldly being called the Beyonder. It was basically a commercial for Mattel’s upcoming Marvel toyline, but it had a major impact on Marvel and its fictional universe. One early surprise in the plot is that Magneto, when abducted, is placed among the heroes, not the villains. When everyone is surprised by this, he defends himself and says that unlike the other criminals, his motives are righteous, making him (in his mind) a good guy. While others try to make use of Magneto as an ally-of-convenience, the Wasp (the leader of the Avengers) objects, seeming furious at him for his crimes.
