The Portalgheist is an enemy fought in Chrono Cross at Viper Manor. These giant fiends disguise themselves as ordinary doorways. Periodically, the door will "blow its cover" and a giant eyeball will appear where once only wooden boards were. The eye scans the room and closes again, unless disturbed by Serge and his party. Portalgheists can be trapped in the Forget-Me-Not Pot and added to the pool of Doppelgangs performed by Sprigg.
Battle and Strategy
At various intervals through the battle, a Portalgheist will open its door and invite additional monsters through it and onto the battle field. Portalgheist summons monsters such as Komodo Pups and Bulbs. Occasionally, Poralgheists are accompanied by two Alphabats. Portalgheists also cast AntiGreen in battle, hoping to prevent Green Elements from being used against it.
Portalgheist is a portmanteau of "portal" and "poltergeist". As the name suggests, this enemy is a door through which monsters come.
The Japanese name of this enemy, Opser Door, is the condensed version of the Observer Door. This suggests that the Portalgheist enemy's fundamental job is to keep a watchful eye out for intruders within Viper Manor.
