- "There was something strange about the way he walked... much more vertical than usual."
- ― Abe Simpson on a cat burglar, The Simpsons
The power to fasten onto and climb vertical and horizontal surfaces without falling.
- Adhesive Climbing
- Molecular Adhesion
- Physical Adherence
- Surface Scaling
- Wall Adhesion/Clinging/Walking/Scaling/Sticking
The user can scale walls and ceilings, no matter how rough or smooth they are. They do not deny gravity, but adhere to surfaces unaided using various ways. However in order to be considered true wall-crawling, the user must be able to maintain balance for long periods of time, compared to Wallrunning where the energy is only temporary.
Beings with superhuman strength or with super strong and dense claws could simply dig their fingers or into a surface, then propelling upward and digging in again, generating the effect of wall-crawling. In some cases, the user may simply be able to make use of any handholds they find, no matter how small, to wall crawl.
Alternatively, the user's body and skin could possess other adhesive properties in common with certain animal species, such as the suction pads of a frog. Those with Reptilian Physiology could have microscopic hair/bristle-like structures on their hands and feet like a gecko, a trait that is shared with those with Insect Physiology and Arachnid Physiology. The use of setae, as well as nanoscale fibers, can allow a user to access electrostatic attraction forces known as Van der Waals Force to interact with positive and negative molecular charges to effectively cling to an object or structure at a molecular level.
- Ceiling Cling - The user clings to the ceiling to either hide or ambush enemies.
- Wall Jump/Wall Kick - The user sticks to a wall and proceeds to jump off of it, often doing so between two walls. This also allows for a form of Supernatural Leap.

- Wall Actions
- Hand or footwear, such as shoes, socks, and gloves may nullify this ability.
- May have to concentrate to remain on the surface.
- May only be able to stick to certain surfaces.
- May not work if the wall is completely smooth with no handholds.
- May be dependent on the user's own center of gravity.
- May not work on frictionless surfaces or frictionless induced objects.
- May be vulnerable to Anti-Adhesion.
