Many ghosts have the power to generate ghost shields at will, to block foes' attacks. These shields typically take on a spherical or flat shape centered on or around the user. Fenton Works, the Guys in White, and Valerie have ghost shield generators that generate shields that function similarly to this power. Human-made ghost shields can also be used for containment, to trap ghosts in place.
