Ghostbusters: Sanctum of SlimeEdit
Geoff is a "professional driver" hired by the Ghostbusters to transport them around New York City in the Ecto-4WD. After the rookie team exits the sewers, Geoff gets a fix on them, arrives, and picks them up. Over the course of driving back to headquarters, Geoff crashes into a fire hydrant and has to make quick repairs to 4WD while the junior team fends off entities. However, Geoff drives into a fissure caused by the Subway Smasher. Following the battle, Geoff answers a call from Ray to return to the Firehouse to meet with Janosz Poha. In a short time, Geoff gets stranded once again in another fissure. Eventually, Geoff and the junior team returns to headquarters and witnesses the reformation of the Relic of Nilhe. He also joins in the celebration following Dumazu's defeat.
As the Ghostbusters prepared for a series of cross country cases across North America, they utilized a modified RV dubbed "Ecto-2". A Post-It Note placed on the schematics left instructions to call Geoff at 555-8632 for a Customization estimate.  During the Tiamat incident, there was a remainder on the Firehouse's second floor chalkboard about asking Geoff about the Ecto-4WD.
