Characters with only a surname, which describes them.
If the word for their surname doesn't have any obvious relation to the character in question, it's Mister Strangenoun. If it's not a character but an offhand description of a prop, look toward I Call It "Vera" (or the demonstrative I Call Him "Mister Happy"). If their name reflects their color, it's also Colorful Theme Naming. If the name coupled with the honorific makes a pun that describes them, it may be "Miss X" Pun. Nothing to do with They Call Me MISTER Tibbs!.
- The Riddler of Batman, born Edward Nashton, legally changed his surname - making him E. Nigma.
- Mr. Sinister of X-Men fame, who took that name because it was the last word his wife said to him as she died, when she realized what a monster he was.
- Wonder Woman Vol 1: Captain Loyal—no first name given—is loyal to the US Navy even under torture.
- Mr. Pump in the novel Going Postal. Of course, he's a Golem who was employed pumping water at the bottom of a well for a few hundred years, so it's an apt description (his 'name' was previously Pump 19). Adora Belle mentions that this is a common naming convention for humans to apply to golems. Golems themselves don't really understand what all the fuss is about; they see themselves as tools and will answer to Pump 19 just as readily as Mr. Pump.
- There's some humor derived from the fact that all the men of Lancre have surnames that don't match their profession: Carpenter is a tailor, Weaver is a thatcher, Carter is a baker, etc.

- Fallen London has the Masters of the Bazaar, who go by "Mr <whatever>" the whatever relating to what they trade in, for example Mr Pages sells books, and Mr Wines sells drinkable things (but mostly alcohol). And then there's Mr Eaten, who got near-destroyed by his fellow masters and whose purpose is, more or less, make people looking for his name suffer horribly.
- El Goonish Shive: Dr. Germahn is a stereotypical German scientist, Principal Verrückt (German for "insane") is a crazy Hitler-lookalike and Dr. Physics Professor is self explanatory.
- From South Park, Mr. Garrison's puppet Mr. Hat, who wears a large and distinctive striped top hat, followed by his replacements, Mr. Stick and Mr. Slave, which literally are a wooden stick and a sex slave respectively.
