In "Bitter Reunions," Skulker uses the device to trap Danny Phantom, who is in Vlad's private lab at Vlad's request. The device shocks Danny, draining his powers and causing him to transform back into his human form. Danny attempts to transform back into his ghost form, but the device renders him powerless.
In "Kindred Spirits," Vlad traps Danny in the spectral energy neutralizer at his Colorado chalet.
The spectral energy neutralizer appears as a black cube with glowing green circuit patterns all over it. When not in use, it is a small cube. When activated, it enlarges and encases the target, leaving a hole at the top for the target's head. On the side, there is a button that says "open" with a picture of a skull on it. Pushing this button deactivates the cube, returning it to its inert state and freeing the target.
