* ChaoticNeutral: Millie full stop.
* MoralEventHorizon: What Felicia did to Stephan. Rejecting him's one thing, toying with him and not feeling bad at all is another.
* NightmareFuel: [[http://ozyandmillie.org/2008/01/02/ozy-and-millie-2022/ This'll definitely scare you from making any sandwiches]]. Also a minor case of FridgeHorror as what exactly is Llewellyn doing with a jar of lost sou-[[MST3KMantra it's probably best we don't ask]].
* StoicWoobie: Ozy for the most part.
* ToyShip:
** Ozy and Millie have a debatable one. On the one hand, there's some [[ShipTease Ship Teasing]] going on in a few select scenes. On the other hand, Ozy and Millie's parents married in the final story arc, making them siblings. On the ''other'' other hand, they're NotBloodSiblings. The prevailing opinion on the fan forum seems to be that either they'll end up together or at least one of them will end up transsexual; seeing as the creator of the strip is the latter herself, this seems plausible. This ends without a resolution; after the wedding, the [[http://www.ozyandmillie.org/d/20081223.html last actual strip]] is them waking up in bunk beds and going outside to play; the last few pics of them [[http://www.ozyandmillie.org/d/20090909.html as]] [[http://www.ozyandmillie.org/d/20090916.html adults]] don't offer any hints either.
*** [[FridgeBrilliance Maybe the author just does not like/want to concentrate on that?]]
** In some of the strips from 2000 Stephen has a crush on Felicia that never goes anywhere, though towards the end Felicia starts to get a little close to [[spoiler: Avery]].
* TastesLikeDiabetes: Timulty. [[JustifiedTrope Though he is only four.]]
* TearJerker: The story about Shelley, Ozy's biological mother. Sort of.
* TheWoobie: Ozy as above. Stephen as well...at least when it comes to romance (While nothing ever happened with Isolde, good or bad, the end of his crushes on Felicia and Stephanie both ended in pain: Felicia pretended to say she would go out with him, then mocked him with her GirlPosse and insulted him causing him to run away and Stephanie was only interested in being friends despite being perfect for him and was instead interested in Jeremy.). Millie is a minor example but has her moments.
* WhatDoYouMeanItsNotForKids: Not that the comic isn't kid-friendly; it is. But a good half of its humor is build around philosophy, politics or economics, not something a kid would care about or understand. Which puts ''Webcomic/OzyAndMillie'' in the tradition of Creator/DCSimpson's influences, such as ''ComicStrip/{{Peanuts}}'', ''ComicStrip/{{Pogo}}'' and ''ComicStrip/BloomCounty''.
