The following is a list of unnamed Arret natives.
Karla Five's father Edit
This Arret native was the father of Karla Five and the grandfather of Karl Four. By 2270, he had de-aged developmentally to the point of being confined in a playpen and wearing diapers. (TAS: "The Counter-Clock Incident")
Under normal Arretian naming conventions, this person would presumably be named Karl Six.
