What’s the Invisible Woman’s Galactus weakness?

Invisible Woman can kill Galactus—what’s revealed

In the latest Marvel comics coverage, Fantastic Four #10 is said to reveal an ultimate weakness for Galactus. The specific claim highlighted in the excerpt is that the weakness originates with A-list hero history tied to the Invisible Woman.

What the story states (with spoilers)

• Galactus’ weakness has been identified in the comic.
• The origin of that weakness is linked to an A-list hero.
• The Invisible Woman is positioned as the key through which the weakness can be acted on.

The excerpt explicitly warns that it contains spoilers for Fantastic Four #10, and it frames the discovery as a major Marvel-universe shake-up, because Galactus is typically treated as nearly unstoppable.

Why it matters

When a story establishes a concrete vulnerability for an entity like Galactus, it changes the stakes for any future cosmic threat involving him. It also re-centers Fantastic Four lore around the Invisible Woman’s significance, making her more central to the broader cosmic continuity.

What’s missing

The provided summary does not specify:

• the exact weakness mechanism,
• the name of the A-list hero involved,
• or the exact moment/scene where the revelation occurs.

So, the most accurate news takeaway is that the comic introduces a new, decisive route to harming Galactus and ties its origin to Invisible Woman-linked A-list hero elements—but the detailed how/what requires the full comic text.
