As far as he knew, across the countless parallel universes of the Marvel Universe, Spider-Man's wall-crawling ability came in two versions.
The first version was the tiny barbed hairs possessed by the original Spider-Man. He relied on minute, barb-like hairs growing from his skin to climb walls.
This was the easiest method to understand, but its use was far too limited. It could only be used for wall-crawling and was nowhere near as powerful as the second version.
The second version was the Electrostatic Adhesion Gwen was using right now, scientifically known as the Van der Waals force. Its principle was described as a weak electrostatic interaction caused by permanent molecular dipoles and instantaneous dipoles. Put simply, it meant manipulating the forces between molecules.
In many parallel universes, Spider-Man could make any part of his body generate an electrostatic effect with an object's surface, creating powerful Electrostatic Adhesion and allowing him to climb walls.
From what he understood, this adhesive force could reach several tons. In the Marvel Universe films, the third-generation Spider-Man had clung firmly to a speeding alien spaceship with just a few fingers. That showed how powerful it was.
Thanks to this absurd adhesion ability, combined with Spider-Man's terrifying baseline strength of twenty tons, he could practically tear apart anything with his bare hands. Even the smoothest surface was useless against him.
In some parallel universes, Spider-Man had even developed an extremely horrifying technique from it.
He would use that adhesion force to directly tear off an enemy's facial skin, leaving behind a bloody five-finger mark on their face.
It was exceptionally vicious!
There were many Spider-Men across countless parallel universes who possessed Electrostatic Adhesion.
But he had never expected the Spider-Woman before him to have it as well.
And judging from her movements, she had clearly
