Abilities
Cellular Disintegration: Brain Storm is a bacterial-like Stand that Urban Guerilla sends out of his hands, which can melt the flesh of anyone touching it. It creates holes and enters inside its victim's body to decompose it further. As Rai Mamezuku points out, once the Stand has made its way into the body it is impossible to remove, requiring immediate amputation to prevent death. However, the Stand is easily washed away with water if it has not entered the body yet.

Trivia

 * The holes that the Stand creates in its victim's body have the appearance of holes in glaciers.
