What is the name of Morty's half-Gazorpian son?

Morty's half-Gazorpian son is Morty Jr., formally named Mortimer Smith Jr.

He is introduced in “Raising Gazorpazorp,” the seventh episode of Rick and Morty’s first season. Morty uses an alien sex robot named Gwendolyn, unknowingly triggering its reproductive function. The robot later gives birth to Morty Jr., who is half human and half Gazorpian.

Morty Jr. inherits the violent instincts associated with Gazorpian males, alarming Morty and the rest of the family. Morty eventually tries to redirect those impulses into writing, and his son produces the book My Horrible Father. The character is often confused with Naruto, but Naruto is a separate, later offspring connected to the events of “Rickdependence Spray.”
