Warning: contains spoilers for Eternals: The Heretic #1!
In the new one-shot comic Eternals: The Heretic, Marvel introduces a new detail which addresses the franchise's former sexism in the ideal way.

The current Eternals ongoing series has established the idea that the Eternals are gender fluid (just on an immortal timeline, explaining why gender appeared fixed in prior stories.)

While Kieron Gillen and Esad Ribic's ongoing Eternals addressed this by having multiple characters resurrect with new gender presentations, the lore of Eternals' power structure remained solely focused on its mighty Patriarchs, the 'grandfathers' of the other Eternals. Marvel's Eternals: The Heretic addresses this in a creative and intriguing way.
