What does it take to be an X-Man?

[Mutant 77]

As simple as that, all other MUTANTS in the 616 Earth are NOT "X-MEN".

To me, "X-MEN" always meant:

Male and female agents of Xavier = the men of Xavier.

[Zelena]

The definition of X-Men is those mutants who were trained by Prof Xavier. That's where the X comes in, it is from 'X'avier.

In a panel (I don’t remember where…), Xavier explained to Moira that the X comes from the X-gene. He added that he was not so vain or something like that.

And you must be a clone of yourself!

[G-Man27]

You're an X-Man if you have the X-Gene, you're able to fight adversity, and you survive the experience

[Lucyinthesky]

Survive adversity, fight for a world that hates and fears you and for all people of planet earth.

[From The Shadows]

Nothing. Everything.

[ComeOnBunny]

What it means to be X-Man is to be Ex human.
