The Real GhostbustersEdit
The Ghost of Christmas Future is a member of a trio of entities who are most famous for showing Ebenezer Scrooge the error of his greedy ways on the Christmas holiday. However, the time lost Ghostbusters accidentally trapped them and stored them into the Containment Unit, thus altering history.  The Ghostbusters impersonated the three ghosts while Egon Spengler extracted them from the Unit and helping restore the timeline to its proper form. Ray Stantz impersonated him when he was accidentally captured.
When the Ghost of Christmas Present possessed Woodrow Wainwright Fraser III, Past and Future visited him for several years in an attempt to coax him back into fulfilling his duty. Finally, on one Christmas Eve, Fraser/Present hired the Ghostbusters to trap the two ghosts. The Ghost of Christmas Future teleported Peter Venkman and Egon Spengler to a possible future where they were approximately aged to their 60's and were forced to battle Gozer, who was in a new Destructor form. After Gozer killed Egon, Peter realized Fraser was being possessed by the Ghost of Christmas Present and wrangled him out. The three ghosts were reunited at long last.
The Ghost of Christmas Future didn't speak, but the Ghost of Christmas Past implied he could speak when Egon rescued them by quoting him. ("Let's take it from the top!") By the company he keeps, one can conclude he is also a benign ghost. Unlike Past and Present, the Ghost of Christmas Future does not appear at a predetermined time, but rather at a moment of its own choosing (much like the future will come when it will), and allows the visions of the possible futures to speak for him.
The P.K.E. Meter registered the ghosts as big and powerful.
