Liberty Island is small island located in New York Harbor best known as the location of the Statue of Liberty.
In need of a something to combat the Psychomagnotheric Slime covering the Manhattan Museum of Art, the Ghostbusters ventured to Liberty Island to animate the Statue of Liberty with positively charged slime. It worked and they departed aboard the statue. Several weeks after Vigo was defeated, an official ceremony was held by the City & County to celebrate the return of the statue to Liberty Island and to award the Ghostbusters with a Key to the City.
Two years later, the Psi Energy Pulse triggered by Ilyssa Selwyn passed through Liberty Island and Statue of Liberty with no apparent paranormal reaction from the latter. The Ghostbusters later found Shandor Island near Liberty Island.
A little after 3 pm on a Friday, the Ghostbusters were alerted of a manifestation on Liberty Island. Due to the events of the dimensional bleed incident, Liberty Island was previously a focused point and suitable choice for Connla's rematerialization. He could continue with his goal to widen the veil to the other side permanently and make night last forever. Murdock flew the Ghostbusters, Kylie Griffin, and Ron Alexander to the island in his helicopter. After Kylie shared her findings on Connla's identity, she instructed him to leave the island as soon as possible so that the noise from the helicopter wouldn't impair Connla's ability to hear her. Ron was eager to get it over with and fired into the paranormal mist. Connla's Army emerged from the mist. Kylie recognized them as the ghosts she saw in a precognitive dream prior. She readied a Trap and called out Connla's name. He couldn't believe she knew his name since it was written. He extended his fingers into the ground and grabbed the Ghostbusters. Kylie punched the pedal and pulled Connla into the Trap. Connla called out to the ghosts and asked them to save him. To the Ghostbusters' surprise, the ghosts grabbed at Connla's head and neck. Peter Venkman and Winston Zeddemore threw out two more Traps. Connla ordered the ghosts to destroy the Ghostbusters and free him then he was completely trapped. To make matters worse, more and more ghosts continued to manifest. Egon Spengler initiated his contingency plan and used his Remote Portal Access Band. The others tried to hold off the ghosts. Egon soon returned and six portals opened. The rest of the Chicago Ghostbusters, Real Ghostbusters of Dimension 68-R, Extreme Ghostbusters of Dimension 68-E, the Ghostbusters of Dimension 80-C, Mike the Golem, and the Ghostbusters of 50-S fired their throwers and emerged from them. Ron was even more jealous of the teleportation tech but Jillian Holtzmann claimed she called dibs first. Egon Spengler from Dimension 68-R, Roland Jackson from Dimension 68-E, and Abby Yates from Dimension 80-C checked their respective P.K.E. Meters and confirmed they trapped every ghost and they were clear. Patty Tolan directed them to look at what they did to the Statue of Liberty's "backyard" but Peter was sure they could smooth it over.
