Eye-Obscuring Hat: Mr. Silly, Mr. Nonsense and Miss Scatterbrain (presumably) have eyes hidden under their hats. Christmas Surprise! (the first appearance of Tenth) was released on its own between Waves Two and Three, and Dr. Thirteenth after Wave Three to coincide with her first formal episode.

Ambiguously Human: The Mr. Men and Little Misses are visually a fantastic race of colorful Living Polyhedrons, but they apparently are human beings. If anything, they look like actual human beings in-universe, but look like talking shapes to us since they're meant to be representations of the virtues and vices anyone in real life can have.Mr. Happy is the 3rd book in the Mr. Men series. Mr. Happy discovers Mr. Miserable (who looks exactly like him) and helps him become happy. Unusually Uninteresting Sight: None of the humans seem to so much as blink at the sight of talking shapes and even engage in regular chatter with them. Cat Scare: Dr. First gets one with an actual cat, who was rummaging through trash and thus appeared to be a hiding robot, shortly before he discovers Cybermen out and about. It's also similar to a Scary Shadow Fakeout. Mr. Uppity appears under the titles Monsieur Malpoli (French), Don Señorito (Spanish), Mr. Ffroenuchel (Welsh), Unser Herr Hochnase (German), 傲慢先生 (Taiwan), 거만씨 (Korean), Ο Κύριος Ακατάδεχτος (Greek), Meneertje Onbeleefd (Dutch), Senhor Malcriado (Portuguese), Fætter Storsnude (Danish). Heel–Face Turn: Many of the rude Mr. Men or Little Miss often pull one at the end of their titular story.

Mr. Snooty is rude to everyone he meets, resulting in everyone calling him "Miserable Old Snooty", he grows out of it after meeting a goblin who punishes him by making him shrink every time he's rude to somebody.Animated Adaptation: To promote the first wave of books, Dr. Twelfth was adapted into a storybook short read by Michelle Gomez, the actress who plays Missy. Our Humans Are Different: Despite the fact they're talking shapes with arms and legs that live among human beings, Mr. Men and Little Misses are human beings themselves. Justified, as they're meant to be abstractions of human beings any reader of their stories can imprint themselves onto. Both Mr Impossible's Lesson and Little Miss Shy And The Fairy Godmother involve Little Miss Shy being put through a gratuitous act of cruelty from one of the meaner characters (Mr. Snooty in the former, and Little Miss Bossy and Little Miss Naughty in the latter) and getting help via magical means. The key difference is that in the former, Mr. Snooty shows some honor at the end and thanks her along with Mr. Bump and Mr. Clumsy for preventing his house from burning down while in the latter, Little Miss Bossy and Little Miss Naughty receive little, if any repercussions for bullying Little Miss Shy for blushing.

Shrinking Violet: Mr. Quiet and his Distaff Counterpart Little Miss Shy. Mr. Quiet initially lives in Loudland (as does Mr. Noisy), where no-one can hear his almost inaudible voice, but later moves to Happyland at Mr. Happy's invitation and gets a job in a library. Little Miss Shy rarely ventures beyond her front garden, until Mr. Funny invites her to a party and she meets Mr. Quiet. Brainwashed and Crazy: The Rani turns the Blue People into her minions and sends them after Dr. Sixth and Peri. Dr. Sixth's enraged shouting at her over this turns out to be sufficient to undo it!David Shaw Parker - Mr. Clever, Mr. Chatterbox, Mr. Nosey, Mr. Muddle, Mr. Snow, Mr. Impossible, Mr. Strong , MiseryLand Jester, Dark Knight, Stormy Knight, Stary Knight, Elves, Father Christmas.

Annual No. 3: Mr. Jelly is in the park, and hears a Sinister Scraping Sound; and is convinced that it's a giant centipede sharpening its claws to tear him to pieces. But it is only Mr. Slow, the gardener, slowly raking the soil.Mister Descriptor: The Mr. Men and Little Misses are all simply called "Mr./Little Miss (Personality or Appearance Trait)". Mr. Chatterbox is cured of his Motor Mouth tendencies by a magic hat that grows until it completely covers him every time he starts talking. Fake-Out Opening: The opening to Mr. Nobody pulls this off by claiming it to be about Mr. Happy before saying "Actually, this isn't about him." He does appear in the story aside from this moment. Long List: Discussed in Dr. Fourth: "In fact, the list of things Daleks can't do is long, but not as long as the list of things that Daleks don't like." This is because the only thing they like is "exterminating things".
