Namor the Sub-Mariner, aka Namor McKenzie, is a fictional character appearing in American comic books published by Marvel Comics, although his origins date to 1939 under Timely Comics.
In "Veteran Guy", they guys blow off doing their assigned patrol duties to converse with the Sub-Mariner, mistaking him for Aquaman. When he tries to explain the differences between the two, he loses the guys' interest because he can't talk to fish like Aquaman who appears and demonstrates. When Sub-Mariner protests that he has wings on his feet, Peter shushes him and tells him that it is over.
