In the mid-1980s, J. Portman Plump opened New York City's newest convention center, Plump Towers. Shortly after a ribbon cutting ceremony with the Mayor, Plump welcomed his first two conventions, the American Association for the Advancement of Oral Hygiene and Deadcon 1. However, when he witnessed the Ghostbusters' methods in the lobby, Plump forbid them from using their equipment and stored the Proton Packs in his office. After conducting their investigation, the Ghostbusters were chased by Deadcon 1's ghosts.
The ghosts kidnapped Plump, who quickly lifted his ban over the Ghostbusters. In the finale of the bust, Plump was used as human shield by the English Ghost and Manitou. Egon shot a nearby disco ball, causing the ghosts to drop Plump. Ray and Winston quickly jumped under Plump to break his fall and ensure they got paid.
- On page nine of Ghostbusters Issue #5, Plump makes a non-canon cameo in Manhattan.
- J. Portman Plump bears a striking resemblance to real-life New York real estate developer Fred Trump, the father of Donald Trump, who constructed the real-life Trump Towers and would later become President of the United States.
