<p>The only Water tribesmen i know that has a last name is Varrick "lknik Blackstone". Who is part of Southern Water Tribe people. Does the North & South Tribe have a significant with last names? If yes then that means Korra must have a last name. Theory on Rather if the last name is inherit from parent to child. or do they choose their own last name or marry into the last name? </p><p>Though the water tribe may not be the only ones that does not familiarize themselves with family or clan last names. Like Zuko family name who doesn't seem to have one. Even Avatar Aang. nor katara and sokka. </p><p>If they do have last names. then what do you think their last name should be. it'll probably be something avatar world-like last names. </p><p>I did a fictional theory on what the atla cast last names would be. well, the ones that doesn't have one. as below: </p><p>Aang Daiji. "Daiji" which means "great compassion" </p><p>Sokka Clearwater </p><p>Katara Clearwater which is a simple last name for a water tribe family. </p><p>Zuko Ryu. -"Ryu" which means dragon in japanese i think. but it so cliche* even for a royal member of the fire nation. </p><p>SO what do YOu guys think? And i not sure what the tlok cast last names would be even for avatar korra and her family. or even mako and bolin's sur-names. </p>
