History LastNameBasis / WesternAnimation

* ''WesternAnimation/StarWarsTheCloneWars'': Obi-Wan Kenobi's [[ArchEnemy archenemies]], especially General Grievous and [[spoiler:Darth Maul]], tend to address him only by his last name, and usually in [[ChewingTheScenery spectacularly]] [[LargeHam hammy]] [[SayMyName fashion]].

* Oddly enough, there were a few moments in ''WesternAnimation/{{Rugrats}}'' where Angelica would address Tommy as "Pickles", despite the fact that they are cousins and share the same last name.

** T.J.'s main rival Lawson, as well as some minor characters (Skeens, Gelman, Mundy, etc.) are mostly known by their last name. This is lampshaded when Gretchen appears at Lawson's house and doesn't know his given name.

** Despite the fact that the head of ISIS is Malory Archer, nearly everyone except Malory addresses her son Sterling as simply "Archer". Pam and Cheryl used to consistently call him "Mr. Archer," but as of the more current seasons Pam has dropped it completely, whereas Cheryl still does it. Malory, on the other hand, almost always goes by "Ms. Archer" except for when Lana and Cyril sometimes call her "Malory."
** At first Archer refers to Ray by his last name "Gillette" but later as "Ray."

* In ''WesternAnimation/{{Amphibia}}'', Sasha occasionally refers to Anne by her last name of Boonchuy.

* "Once-ler" is implied to be a surname in ''Literature/TheLorax'' 70s special.

* ''WesternAnimation/StarTrekLowerDecks'' reverses the trend toward FirstNameBasis seen in (chronologically) recent shows such as ''Series/StarTrekVoyager'' by having the characters refer to each other by last name at almost all times, even if they're close friends.
