Artificial Ghost Portals
Fenton Ghost Portal
The Fenton Ghost Portal is located in the Fenton Works lab. It works perfectly, but its one major flaw is that its "On" switch is located inside the portal. Because of this, a curious Danny accidentally activated the portal while standing inside it, causing the accident that gave him his ghost powers.
Other Ghost Portals
- Prototype Ghost Portal: Twenty years before the series takes place, Jack, Maddie, and Vlad Masters built an experimental version of the ghost portal during their college years. An accident involving this portal infected Vlad with ecto-acne, destroying his social life and ruining his chances at winning Maddie, but also gave him his ghost powers.
- Vlad's Ghost Portal: Vlad Masters has his own ghost portal in his mansion.
- Maddie's Ghost Portal: In the alternate timeline seen in "Masters of All Time," Maddie created a ghost portal of her own in Vlad's mansion.
- Fenton Bazooka: The shots from this Fenton weapon generate temporary ghost portals.
- Unnamed ghost portal device: This small device remotely creates portals between Earth and the Ghost Zone at the push of a button. Sometime between "13" and "Lucky in Love," Johnny 13 stole this device from the Fenton Works' lab and mounted it on his motorcycle for his own use.
- Ghost Portal Creation: Some ghosts, such as Dark Danny, Wulf, and Clockwork have the power to create ghost portals at will.
Natural Ghost Portals
There are numerous natural portals between the Ghost Zone and Earth that lead to various locations and time periods, such as the Salem witch trials, the Bermuda Triangle, and the rings of Saturn. These portals can be located through the use of the Infi-map.
- Full-sized man-made ghost portals have ecto-filtrators that need to be changed every six months, or else they will overload and cause an explosion.
- The password Danny uses to lock the Fenton Portal in "Livin' Large" is "Open Sesame."
