WARNING: Contains Potential Spoilers for FANTASTIC FOUR #31 (2025)!

The Fantastic Four’s Invisible Woman is best known for her invisibility. However, Sue Storm is so much more than this singular and often character-defining power, boasting a powerset that also includes force field construction, energy projection, and more. Now, this iconic hero has revealed yet another ability, proving she has even more powers up her sleeve and cementing her status as the team’s ultimate secret weapon.

Fantastic Four #31 by Ryan North, Cory Smith, Oren Junior, and Jesus Aburtov has officially arrived in comic shops and on digital platforms, continuing the story of the Fantastic Four as they adapt to a new world order under Doctor Doom, Marvel’s new Sorcerer Supreme.

While the issue delivers several major developments, one moment that may be easy to overlook is a subtle but significant reveal: the Invisible Woman is even more powerful than fans previously believed. In a blink-and-you-miss-it scene, North introduces a new but entirely plausible ability: sonokinesis, or in other words, the ability to control sound. However, there's a catch.

It’s Official: Invisible Woman’s Force Fields Are Soundproof

Fantastic Four #31 reveals that the team as a whole are losing their powers one by one. In one pivotal moment, the Human Torch begins to plummet from the sky when his ‘Flame On’ ability suddenly turns into a 'Flame Off.' Fortunately, Mr. Fantastic catches Johnny just in time. Since the incident happens in front of a crowd, Johnny grows concerned that their enemies might catch on, saying, “...we’ve got a reputation to maintain. I don’t want our enemies knowing we’re down to the Fantastic Two.” To save face, he asks his sister to drop her soundproof force field so he can loudly claim that his power loss was just an act, a trick to fool their adversary.

While this moment provides some comic relief, with Johnny dramatically shouting, “I still have my powers, of course! And I always will!!!” it also serves as direct confirmation that Sue has sound-related abilities tied to her force fields. Although some fans may have already assumed or suspected this, Fantastic Four #31 finally makes it explicit: Sue can block and dampen sound with her force fields. Her invisibility already makes her one of the most stealth-capable and skilled heroes in the Marvel Universe, but now, with confirmed sound suppression, she’s even more stealth-savvy than ever.

Defensive Sonokinesis: Invisible Woman’s Unique Soundproofing Abilities Explained

The comic quickly glosses over the fact that Sue’s force fields are soundproof, offering little detail or explanation. However, it appears that her sound-related abilities are directly tied to her force fields, indicating that she has a specific type of sonokinesis: defensive sonokinesis or sound dampening. Given this connection, it’s unlikely she possesses full sonokinesis, which would allow complete control over sound waves, beyond just dampening with her force fields. While there are some clear limitations to Invisible Woman’s new power, it is still an immensely cool addition to her powerset arsenal.
