Ghost Shields are barriers made of solidified ecto-energy.
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 or humans in place.
The immense power of certain ghosts like Danny, Dark Danny, and the Hydra could break apart ghost shields.
- Ice Shield: A ghost with cryokinesis can create a shield made of cold energy to protect against fire attacks.
- Reflective Shield: Can reflect attacks such as ghost rays. Often used by Vlad Plasmius.
- Electric Shield: Electric ghosts like Technus can create electric ghost shields that can be used to electrocute enemies in addition to defense.
