He’s been part of a wildly popular superhero team since its very beginning.

But there’s something we never knew about Bobby Drake, aka Iceman of the X-Men.

Wednesday’s issue of “All-New X-Men” No. 40 reveals the truth: Bobby is gay.

“There are thousands if not millions of stories of people who, for many different reasons, felt the need to hide their sexuality,” Brian Michael Bendis, who wrote the issue, said in a statement to CNN. “The X-Men, with the conceit of time travel, give us a fascinating platform in which to examine such personal journeys. This is just the first little chapter of a much larger story that will be told.”

Iceman’s outing happens in an unusual manner. In the “All-New X-Men” storyline, members of the X-Men team travel to the past, as younger versions of themselves.

Mind-reading mutant Jean Grey (also an X-Men original) asks Bobby why he calls women “hot,” when she knows he is gay.

In comic book pages provided to CNN, Bobby doesn’t immediately acknowledge that she is telling the truth.

The character of Iceman is perhaps best known for his appearances in many of the “X-Men” films, as well as the 1981 animated series “Spider-Man and His Amazing Friends.”
