Part four of "Mass Hysteria!" continues in issue sixteen of Ghostbusters, and the cover says it all...Dana Barrett and Louis Tully have been possessed again, but this time from Gozer's sister, Tiamat. They're in a building on the Upper West Side, and we see all nine team members climbing up dozens of sets of stairs, similar to the scene in which the original four Ghostbusters climbed up in the first film. Some comical moments happen as they climb up, like "The Rookie" saying, "At least it's not the Sears Tower," and Peter saying, "Yeah, yeah...you guys and your Sears Tower," since the Rookie has his franchise out of Chicago and Peter being a true New Yorker. Then an apparition of a judge shows up, telling them they're charged with interfering with the destructor, and how do they plead? Winston shows the ghost judge how they plead...with a ghost trap.
They continue up the stairs and they run into older, future versions of Peter, Egon, Ray, and Winston. The older Ghostbusters give their younger counterparts advice and information about Tiamat. As they approach the top of the stairs, Peter tells the newer members about facing a God-level threat, and when he's done talking, he kicks the door open. Once open, they notice a ziggurat with activity going on at the top, so they go up some more stairs. As they're heading up, they come across the possessed Dana and Louis, and they try messing with their minds, but Peter knows what kind of games Tiamat is playing, so he doesn't fall for anything Dana or Louis say.
Tiamat finally shows herself and changes the appearances of Dana and Louis. They are transformed into griffin-like creatures, or like Janine would say, "bird-things." All nine Ghostbusters fire their proton streams at Tiamat, but nothing happens. Then, Tiamat changes her form into a five-headed dragon, and Peter, Ray, and Egon think of one idea that worked with Gozer...crossing the streams. All nine members prepare simultaneously and fire at Tiamat. As Tiamat screams, "NO!" a bright flash of white light reflects the area. As it starts to fade, Winston tells the team to keep it up, but Egon tells them to cut them, and the team stops firing. Dana and Louis come back to, and their possessions are over. Just when the team thinks it can possibly be over, the red rain (that started falling when Tiamat first appeared in issue thirteen), starts coming down, and her laughter is heard in the background. The story ends here, but it's far from being over.
So far, the celebration of The Ghostbusters thirtieth anniversary is momentous, and this "Mass Hysteria" story arc is a great example of this. Everything that fans love about this series continues strong with every issue. It's great to see the entire team of nine working together, and seeing them climbing up the staircases is a warm nod to the original film, and it brought back memories. It's also nice to see Dana and Louis make a long-awaited appearance in this series, and this story arc is a perfect way to bring these two legendary characters back into the lives of Janine, Egon, Peter, Ray, and Winston. It's unfortunate that they get repossessed, but the Ghostbusters are there to make things right. As per usual, Erik Burnham brings us another great story, Dan Schoening's artwork is just perfect for this series, and Luis Antonio Delgado's colors illuminate off of the tablet screen. I give Ghostbusters #16 a four and a half out of five stars, damn near perfect! Ghostbusters #16 has 25 color pages and is available now for $3.99 in print or on digital formats.
