Reader Rodrigo M. wrote in to ask, "[W]hat makes Magneto's helmet immune to telepathy? Is it its shape? Is it the metal it is made for? Why there isn't more helmets like that? Why not every member of the Brotherhood wear one helmet as well? What made it unique? "

Magneto's famous helmet was designed by Jack Kirby and it was in use right from the first appearance of Magneto in X-Men #1...

Anyhow, early issues showed Magneto interacting with Professor X on the astral plane, showing Magneto to have a powerful mental prowess...

The X-Men was a series where Stan Lee seemed to care the least about, in terms of consistent plot points. He seemed to just try all sorts of odd plot ideas that he would then quickly dismiss, like the idea that Magneto could project his mind into the astral plane just like Professor X...

Even during Chris Claremont's run on X-Men, during a flashback sequence to when Xavier and Magneto first met each other, Xavier was struck by the fact that he couldn't read Magneto's mind even without Magneto wearing a helmet at the time. However, in later stories, it was retconned out (through the Official Handbook of the Marvel Universe, of all places) that Magneto did not really have telepathic powers outside of perhaps a slight ability to protect his mind from telepaths (which, oddly enough, is a fairly common thing in the X-Men Universe, as Gambit and Wolverine both have the ability to protect their minds from telepathy)

Later, during X-Men vs. Avengers #4, Magneto was shown creating a special helmet that gave him telepathic powers...

Now, Magneto DOES have a helmet that protects him from telepathic powers. So how did it come about?

The answer seems to lie in X-Factor Annual #4, in a story by Ralph Macchio and John Byrne that was a sort of follow-up to X-Men vs. Avengers (which was changed at the last minute so that Roger Stern's original story for that series did not get printed as Stern intended it. Instead, Tom DeFalco wrote the final issue, so Stern has nothing to do with the bit with the helmet being built to give him telepathic powers). I would suspect that there is a decent chance that Stern's original views on the helmet were closer to what Byrne and Macchio came up with in the X-Factor Annual story.

In the story, Magneto now notes that the helmet that he used in X-Men vs. Avengers was actually not built FOR that story, which is how DeFalco described it in that X-Men vs. Avengers story. Instead, the helmet is now an existing one that Magneto just adapted for his purposes in that X-Men vs. Avengers story.

In other words, the implication is that the helmet had always had circuitry in it that allowed Magneto to either have telepathic powers or, in the alternative, to block telepathic powers.

Therefore, that is why his helmet blocks telepathy, as we saw in later versions of his helmet, as well, like in Cullen Bunn's Magneto series...

So there ya go, Rodrigo!
