Elliot: Um, well, what with me being a cat and all... Cat?
Damien: All of you animal people have horrible names.
Elliot: Well, uh, what can you expect? We were named by scientists, not writers or cartoonists.
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 "Mr. Happy"). If their name reflects their color, it's also Colorful Theme Naming. Nothing to do with They Call Me Mister Tibbs.
- Mr. Big in the first episode of Get Smart.
- Mr. Pump in the Discworld 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.
- The Mr. Men and Little Misses are all named "Mr/Little Miss (Character's dominant personality trait)".
- The characters in Clue are named after the color of their pieces: Mr. Green, Mrs. White, Ms. Scarlet, Mrs. Peacock, Colonel Mustard, and Professor Plum.
- In Demon: The Descent, the title characters are known to refer to themselves as Mr. Joy or Miss Book or the like. The identifier is often derived from the demon's original purpose.
- The song "Mister Cellophane" from Chicago.
- 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.
- Sunless Skies has Mr. Pennies, who is found in Lustrum, and Mr. Menagerie, who roams the Reach. It is glaringly obvious that they're members of the same species as the Masters of the Bazaar, but with much, much less power. The Great Chain of Being collapsing on itself as soon as the stars started dropping did a number on their authority.
- From South Park, Mr. Garrison's puppet Mr. Hat, followed by his replacements, Mr. Stick and Mr. Slave.
