Examples of LastNameBasis in Comic Books.
----
* In the ''Franchise/{{Tintin}}'' series, Captain Haddock is never called by anything other than his last name. Even his best friend, Tintin, is not entirely sure what his first name is.
--> '''Haddock (after a blow to the head gives him amnesia):''' Who's captain here, you or me?
--> '''Tintin:''' You, of course. You're Captain Haddock.
--> '''Haddock:''' How ridiculous! What's my first name, then?
--> '''Tintin:''' Archibald, isn't it?
** The same goes for the Thom(p)sons, whose first names are never given, and for Calculus, whose first name is quite rarely used, but exists.
** And other characters suffer the opposite treatment: Tintin's full name is unknown, and whether it's his first name or last name is unclear (could also be a nickname); also Nestor, the Captain's butler, has no last name.
* ''{{ComicBook/Sabretooth}}'' aka Victor Creed, is usually just referred to as "Creed" by majority of people he interacts with. Some who have referred to him as "Victor" are Bonnie -a human woman he had a relationship with, and Magneto. Creed in turn refers to Magneto by his first-name,"Eric."
** Monet calls him Victor in passing during chapter 6 of ''ComicBook/UncannyXMen2015''. But Creed quickly called her out on it, saying that she usually calls him Creed, Sabretooth, or a variety of more insulting names.
* All the Judges in ''ComicBook/JudgeDredd'' are known primarily by their last name. Hardly anyone calls Dredd "Joseph" (Dredd's clone father Fargo being one exception), or addresses Anderson and Hershey with "Cassandra" or "Barbara", respectively.
* ComicBook/IronMan: James '''Jim''' Rhodes is commonly known by a diminutive of his last name Rhodey.
* ComicBook/{{Morbius}} the Living Vampire is almost always called by his last name, both in and out of universe. Only friends (occasionally) use his first name, Michael, "Or they would, if I had any."
