Examples of Last-Name Basis in Web Original.
- The Adventures of Jamie Watson and Sherlock Holmes: Although we know Lestrade's first name, she prefers to be called by her surname.
- In The Autobiography of Jane Eyre, Mr Rochester calls Jane, who is his employee and live-in tutor for his daughter Adele, just Jane in their second episode. He likes her, and cannot be bothered with "Ms Eyre". She however calls her boss Mr Rochester.
- Enforced in Autodale. The citizens of Autodale don't have first names. The only named citizens we see are Mr. Robinson, Mrs. Robinson, and Robinson Junior, with Junior becoming the new Mr. Robinson once the old one is branded Ugly. Autodale treats its citizens like cogs in a machine, they're there only to work and raise replacements for themselves, so it makes sense that something personal like a first name isn't desired.
- Below Board, being a Police Procedural, does this with almost all of its characters. The exception would be Chet Holloway, who goes by his first name throughout.
- In the Amazon series Betas, the first name of Randall Hobbes isn't revealed until the final episode, prompting surprise in two other characters.
- Perry and LaFontaine in Carmilla the Series. In LaFontaine's case it's because they're non-binary and prefer to dissociate from their feminine first name, Susan.
- Chronicle of the Annoying Quest offers us with Voliostramort Guy.Guy: Everyone just calls me Guy though, cause I hate my first name.
- Critical Role: Nobody calls Gilmore by his first name. The players - who have been playing the same campaign for two years already - didn't even know what it was, until Matt casually mentioned in Episode 14 that it was "Sean".
- The Lizzie Bennet Diaries: Darcy is just simply referred by his surname Darcy to everybody. Everybody calls Darcy but his sister Gigi. She calls him William.
- Meta Runner. Derek Lucks, the Big Bad of the first two seasons, is always referred to by his last name, with his first name not being revealed until late into Season 2.
- Most characters in Red vs. Blue save Sarge, Doc (real name Frank DuFresne), Grif's sister (although she's very rarely referred to by her first name Kaikaina, or "Kai"), Lopez, the Freelancers, and any tertiary characters, due to the characters being in the military. Church didn't even know Tucker's first name when he asked him partway through the series, despite working with him for months. The cast's full names are Leonard L. Church, Michael J. Caboose, Lavernius Tucker, Richard Simmons, Franklin Delano Donut, and Dexter Grif.
- RWBY:
- Lie Ren is referred to in show as just Ren, and provides the R to his team's name (JNPR). This was the subject of much fan speculation about Western/Eastern name order, until Volume 4 confirmed that he goes by his surname.
- Professor Ozpin is variously called "Professor", "Ozpin" or "Oz". However, "Ozpin" is actually his surname. His personal name has never been revealed or hinted at, but writers have confirmed it exists. His original name is Ozma, an example of Only One Name. Calling him "Oz" is therefore a form of continuity for characters who know that he's immortal and reincarnates into different host bodies.
- Shrapnel: Reznya’s full name is Liliya Reznya, but very few characters call her by her first name.
- In Tankmen, while you would think Captain's referred to by rank, he's not; his full name is John Captain, and his actual rank is Sergeant.
