Rachel Unglighter used her demonic magic to power the Ecto-1, now dubbed Ecto-10, and perform time jumps. These jumps were targeted specifically to each displaced Ghostbusters' Proton Pack, each with their own unique energy signature.
The Ecto-1 designation was used again after the Displaced Aggression event, for awhile, as evidenced by the appearance and license plate.
