Cement

Cement is a Quirk used by Ken Ishiyama.

Information
This Quirk gives Ken the ability to manipulate cement-based material simply by being in contact with the surface.

Because of the nature of this Quirk, Ken has a large combat advantage on urban areas because of the abundance of concrete. Inversely, he holds little combat ability on settings where concrete is rare or nonexistent, such as in the countryside.

In the anime, Ken' hands appear to glow in a faint green light whenever he's using his Quirk.
