The Ultimate Invasion

A Fear Ghost dwelling in a basement remembered when the Ghostbusters attacked him and overcame his fear of humans. He snuck into the Firehouse and freed the Mirror Demon, the Leprechaun, Achira, and a biker ghost. The Mirror Demon and the Leprechaun were recaptured first. The biker ghost was recaptured at the museum and the Fear Ghost was also trapped. Achira was more elusive as she wanted to have revenge. She wasn't very wise and ended up recaptured and restored to the Containment Grid.
