Wall Man is a pyrokinetic ghost that appears in the form of a giant face. It was one of Janna's lieutenants. The Ghostbusters defeated it inside a burning building, and later trapped it in Janna's realm.

Its attacks consist of a giant face of fire appearing out of one of the two walls in its room (sometimes upside down) and either spitting three orbs at the player, or by spitting out a pyrokinetic version of the Cell Ghost, which oozes along the ground. His weak point is his mouth. As he takes damage he changes from fiery red to blue. When defeated, his heat dissipates and he becomes a charred husk that cracks and disintegrates, yielding a corner of the clay tablet.
