Device Type: Delivery Vehicle
First Appearance: Ratman Chapter 20

Designed and built in secret by his father, Fatman gained a new weapon in his battle against his company's biggest rival Bison Burger. Faster and able carry more pizzas than his scooter, Fatman had a chance of beating his rival. However, his father didn't want his mother to know about it. He also didn't want Warner Bros. or DC Comics to find out either since the car looked suspiciously like another caped crusader's.

However, the car would not be in Fatman's service for very long as it was destroyed beyond repair during its maiden drive. A scuffle between heroes left the Fat-Mobile as a pile of junk. The question of whether or not it had other abilities would remain unanswered as Fatman later went back to using his scooter.
