During Rock Revenge Fest XIV, Rowan North planted a Hyper-Ionization Device on a table the Wardrobe Room of the Stonebrook Theatre. Mayhem manifested soon after in a highly ionized state. It emerged from a wall vent and attacked a janitor named Fernando. It started tossing him around the room. The only reason he survived was Jonathan the Theater Manager. He screamed and scared the entity off. Fernando thought it was the Devil. Jonathan called the Ghostbusters. The Ghostbusters arrived and started investigating the scene. Abby Yates found the Hyper-Ionization Device. Patty Tolan entered the Laundry Room and it was filled with mannequins. Patty called it a room full of nightmares and turned around. One of the mannequin's head turned. Patty told herself she had a good job at the MTA. The mannequin followed her around the corner. Patty turned around and saw a mannequin right behind her. She tried to remember if it was there before. She told it not to answer. The mannequin chased her. Patty entered the Wardrobe Room and quickly closed the door and used herself as a barricade. Jillian Holtzmann and Erin Gilbert were already inside with Abby. The mannequin kicked a hole in the door near Patty's crotch. Patty screamed then ran over to the others. It kicked its way in through the door with its joints glowing red. Abby realized the ghost performed a full paranormal transferal embodiment and her and Erin's theories on spectral possession were true. Erin wanted that ghost. They opened fire on the mannequin. After a few seconds, Mayhem emerged as they blasted the mannequin apart. It screeched and flew off. Erin ordered them to run after Mayhem. They chased it down the hall. Mayhem snarled. They fired at it. Mayhem screeched and flew up through the ceiling leaving Ectoplasm behind.
The Beasts Of Mayhem performed "Want Some More" as Mayhem rose up through the floor to the stage. The Beasts keep on playing. People in crowd pointed at Mayhem. The lead singer noticed it and gestured, stoked, to the lightboard operator. The operator shouted it wasn't his stage effect. The Ghostbusters stopped at the edge of the back stage. Erin realized the Hyper-Ionization Device was making the ghosts stronger and pointed out Mayhem was super ionized. Abby added it was "super not-benign." Patty remarked the music was so terrible, it made the ghost more angry. She demanded the Beasts play something gentle. The singer addressed Mayhem, still thinking it was a stage effect, and improvised, claiming they summoned Satan himself. Mayhem charged and shoved the singer backwards into the speakers. The crowd cheered. Two spectators high fived each other. The Ghostbusters ran onto the stage. They opened fire starting with Patty then Erin then Holtzmann and lastly, Abby. Mayhem dodged the streams. Jonathan screamed the auditorium was Art Deco, calling them idiots, and exclaimed to aim for the ghost. An Art Deco piece was blasted off a wall. Jonathan screamed like a high pitched little girl. Abby told Patty to take one aisle and she would take the far one. Patty and Abby ordered the people to clear the aisle but no one listened. Abby jumped off and had the mosh pit carry her off. She ordered them to move her left then to watch the rings. Patty declared she was about to save them from ghosts then jumped. The crowd stepped aside. Patty landed on her pack between them. Erin oohed. Patty didn't care if it was a race thing or a lady thing, she was mad as hell. She yelled at them to pick her up. Abby ordered them to the people to put her down then thanked them.
Mayhem perched on Patty's shoulders as she got up. The Beasts stopped playing, too. Abby instructed Patty to stay still. Erin tried to tell her. Patty told her she didn't have to tell her anything. Erin kept trying to tell her but Patty refused and told her she really needed her not to tell her anything. Holtzmann insisted. Patty declared she was tired. Erin insisted. Patty proposed she was just going to go ahead and take off. Erin didn't think that was a good idea. Patty walked away. The others called out to her. Patty muttered to herself not to piss off the ghost and told them she was going back to her MTA booth. A couple readied a selfie stick. Patty slowly walked through the crowd but the selfie was taken at Patty's expense. Patty couldn't believe they did that. Abby signaled the others to shoot Mayhem. Erin told Patty to stay still. Abby asked everyone not to hit Patty anywhere important. Patty exclaimed. Erin, Abby, and Holtzmann shot Mayhem. It screeched and hopped off Patty's shoulders. Patty fired at it, too. Abby told Holtzmann to open the Trap. Holtzmann turned off her thrower and reached for the Trap on the underside of her Proton Pack and threw it onto the stage. Holtzmann informed them she was going to open it on three. Patty exclaimed at Holtzmann. Holtzmann swiped her Upper Arm Remote Trigger and the wired pedal shot out from the side of the Trap. Holtzmann counted down to two and rested her foot above the pedal. Patty yelled at her to open it. Holtzmann quickly counted down to one and stomped the pedal. The Trap opened. She resumed firing at Mayhem then told Erin and Abby they were doing great but asked Patty to try a little harder. They steered Mayhem over to the Trap. Patty ordered the ghost into the Trap. The trap pulled in Mayhem at 4:32 pm. Holtzmann stomped the pedal. The Trap closed. Patty ran back up to the stage. Erin asked if they caught it. Holtzmann declared they put a ghost in a box. She held out the Trap as steam hissed from it. The crowd cheered. The Beasts resumed performing their song. Erin shouted "Yes!" The singer declared they were the Beasts of Mayhem. Holtzmann grabbed the guitar away from one of the performers and smashed on the stage. The crowd cheered. Holtzmann whooped. She tossed it back and said she couldn't pay for it. Ozzy Osbourne saw the bust from back stage and became upset. A NY1 News reporter spoke with the Ghostbusters as they exited the theatre. The crowd cheered and high fived them. Abby informed the reporter they were scientists and were in pursuit of the unanswerable questions and, really, to pursue truth. Erin declared they were the Ghostbusters.
Later in the afternoon, Martin Heiss visited the Ghostbusters' Headquarters intent on debunking their claim ghosts were real. After some tense moments, Heiss's taunts got to Erin despite Abby's pleads. As soon as Abby turned away, Erin stomped the pedal and the Trap opened. Heiss cheered her on. Erin and Abby cringed. Erin quickly apologized. Heiss mockingly referred to Mayhem as Casper. Suddenly, Mayhem manifested, flied out of the Trap, carried Heiss through the window and dropped him as it flew away. During the battle at Times Square, he attacked Abby, lifting her off the ground and carrying her for a distance before Erin shot a proton beam at him. He later targeted Holtzmann, but Patty was ready for him with her Ghost Chipper. It pulled Mayhem through and neutralized it. Erin sidestepped its "shredded" mass as it was ejected from the Chipper.
