The Box Ghost is a running gag ghoul who constantly fights with cardboard and anything square (and the occasional bubble wrap). He is incompetent in his attempts to scare people and is barely taken seriously by either the heroes or the other ghosts. He was almost successful in taking over Amity Park by using Pandora's Box, but failed. Despite it, Box Ghost remains determined regardless, shouting quotes such as "Beware, for I am the Box Ghost!" when approaching foes. In an alternate future portrayed in "The Ultimate Enemy", he is married to the Lunch Lady Ghost and has a daughter with her (Box Lunch).
The Box Ghost appears as a NPC in Nicktoons Unite! He can been seen as one of the prisoners from the Ghost Zone prison. You have to talk with him to get out of the prison.
Nicktoons: Toons WarsEdit
The Box Ghost appears as an assist character in Nicktoons: Toons Wars.
When summoned the Box Ghost he will float into the air and say: "Beware, for I am the Box Ghost!" and then he will summon some boxes in his hands and throw them down on the stage towards the opponent. The boxes go very fast but don't do much damage.
