Who is the villain?

It has been revealed that the demon Garraka will be causing chaos in New York after releasing the Death Chill onto the city.

However, that may not be the only villain of the movie. 

Jason Reitman, who directed 'Afterlife' and co-wrote 'Frozen Empire' with Gil Kenan has hinted that the dastardly Vigo the Carpathian from 'Ghostbusters II' may be making his return. 

He said: "There is a lot of time and opportunity for Vigo the Carpathian to make his return. Look, are you saying that’s the only painting of Vigo the Carpathian? Maybe, he’s riding a horse in another one, maybe, impaling someone in another one.”
