While the details of how the Fantastic Four—Marvel’s first superhero team—got their powers have changed a bit over the years, depending on the writer handling their tales, the main beats have remained the same: the quartets go to space for exploration, get bathed in cosmic rays, and boom, they have fantastic abilities.

The new poster Marvel just dropped—using art from the cover of 1961’s Fantastic Four #1—suggests that part may be changing this coming March, however.

Does the Fantastic Four’s origin need adjusting, though? We just got the characters back into publication rotation. Does the source of their powers have to be a who?  Really, this bit is not enough to get us worried. We know this kind of marketing is meant to stir discussion before the story, so let’s not go Chicken Little yet. As always, let’s wait and see.
