Examples of LastNameBasis in {{Webcomics}}.
----
* Parley from ''Webcomic/GunnerkriggCourt'' is called by her last name, because everyone's too nice to call her [[TomboyishName George]].
* Johnathan Gabriel from ''PennyArcade'' usually goes by "Gabe."
* Most of the pilots in ''Webcomic/{{Angels2200}}'' are referred to by their callsign or last name.
** Nicknames instead of first or last names are pretty common among enlisted troops of all services, especially to enforce a OneSteveLimit if there's more than one soldier of the same last name and rank.
* Nolan from ''RegularGuy''.
* The title character of ''Webcomic/ItsWalky'' goes by Walkerton. He doesn't actually LIKE his nickname Walky (At best he tolerates it, there are only a few characters he actually doesn't mind calling him that). Almost no one calls him "David".
** Bonus points because even ''his parents'' call him Walky.
* All of the government-employed characters in ''Doomsday, My Dear'' refer to each other by last name: Zahra, Bowden, Young, et cetera. A few characters refer to Khepry and Chet by their first names, but no one uses Cyril's.
* BittersweetCandyBowl has Alec [=McCain=], who is only referred to by his first name by Sue.
* Jardren Stiggs from ''Webcomic/ProphecyOfTheCircle'' prefers being called by his last name, even by friends.
* 25th Baam from ''Webcomic/TowerOfGod'' calls his best friend, Koon Agero Agnis, simply Mr. Koon.
* [[GravityMaster Muneca Powell]] of ''Webcomic/{{Pacificators}}'' is such a ProperLady, she even calls ''her best friend'' [[PlayingWithFire Kathy Lee]] by her last name. The only time Muneca doesn't refer to somebody by their last name is when speaking [[FriendToAllChildren with children]].
** It is implied that this is part of the reason why Muneca [[DefrostingIceQueen warmed up]] so quickly to [[NewMeat Daryl]] [[LightEmUp Smithson]], because Daryl happily complied with this, whereas Muneca's other teammates give her grief over this.
* In ''Supernatural Law'' by Batton Lash, Alanna Wolff and Jeff Byrd refer to each other by their surnames, though they are clearly both friends and business partners, if not each others' LoveInterest.
