Kevin uses Superman's(BVS: Dawn of Justice form) hairpiece but in tan. He has the standard new Ghostbusters jumpsuit, with a nametag that says "Kevin." He does not have a proton pack. He has black glasses, stubble around his face, and stubble in his moustache area.
When Abby Yates' Ghostbusters started recruiting, Kevin accepted a job as a receptionist(presumably due to him possibly not having a job due to his low intelligence). However, he was possessed by occultist Rowan North, who was in his ghost form. He proceeded to do Rowan's bidding until Rowan left him in favor of a larger, more powerful body. Kevin recovered and continued to work as the Ghostbusters' receptionist.
