Part of what has made Scott Lang such an endearing and well-liked character in the Marvel Cinematic Universe has been how grounded the hero has remained even in the face of the most outrageous events. As Ant-Man, he's talked to ants, entered the Quantum Realm, and traveled through time, and yet, he's never lost his charm or the ability to process otherwise surreal and traumatic situations. This was also why he, in the MCU, was the perfect choice to write a novel that served as a memoir of his time as Ant-Man and a glimpse at the larger universe.
