- Adorkable: Dinky. She doesn't have a lot in the way of social skills, and believes that reprogramming a robot would be an easier, more effective route to take than going out and meeting new ponies.
- Author's Saving Throw:
- Some readers were turned off by Twilight's icy attitude toward Cupcake and Carrot in X-Questrians, something the author realized was a mistake, so he wrote in an explanation (stress over hunting Gustav and lack of sleep) and had her have a Jerkass Realization.
- The Retcon that made the characters anthro has not been accepted by all the fans. This even led to much arguing among the Production Posse, eventually leading to the retcon being undone.
- Crack Pairing: Fans seem more than willing to accept Fenrir/Pinkie Pie after the latter casually comments that the former has a sexy voice. The fact that she casually mentions a date (not saying with who) in the first chapter of the Longbox Anthology as she's telling her sister about the events of Soar doesn't really do much to dissuade the idea. It's made canon in part 2 of that story when Lin uses a Soul Gaze on Pinkie, and among other things sees an image of Fenrir surrounded by cartoon hearts.
- Hilarious in Hindsight:
- Harmonys Warriors has Daring Do as a major character in Soar, and Ahuizotl as a Starter Villain in Iron Mare, some time before the season 4 episode Daring Dont revealed that they were real beings in the main MLP:FIM verse as well!
- Flutterhulk and Soar become much more amusing after watching Power Ponies, as both Fluttershy and Rainbow Dash have similar powers in that episode.
- Rainbow Dash and Trixie being Thor and Loki respectively gets a lot funnier with the announcement of a Friends Forever issue focusing on the two of them. The same applies to Zecora meeting Fluttershy in Flutterhulk when their issue is announced.
- Rainbow Dash as a Thor stand-in has become doubly hilarious since Marvel announced that a woman would be taking up the title of Thor.
- Jerkass Woobie:
- Trixie. She steals other ponies' husbands for her own pleasure (often without the husband's knowledge), she treats her servants badly and also has a constant antagonistic relationship towards Spitfire. She's also been unknowingly living a lie for her entire life, and seems to have suffered various other wrongs in her past. Of course, upon the revelation she was adopted, she promptly begins to plan A Final Solution with the complete and total genocide of the Changelings.
- Diamond Tiara in Spider-Colt is still rather bitchy, but is also shown to be suffering from uncontrolled psychic powers and crystals inexplicably appearing over her body. Suffice to say she doesn't take it well.
- Narm Charm: Applejack's notification that she's been selected for Project Rebirth reads like an over the top, propaganda laden recruitment poster. And it is wonderful.
- Squick: Gustav suggests that him, Angel and Marie have some Three-Way Sex at one point, much to both the audiences and Angel's discomfort. Further enhanced by the fact that Gustav seems to treat Angel like a slave.
- Strawman Has a Point: Silver Belle is a Jerkass, but his views on sacrificing smaller numbers of soldiers and civilians for the sake of winning the war is purely pragmatic.
- The Woobie: Fluttershy in Flutterhulk. She was bullied a lot as a filly, her father's well meaning attempts to help her led to her condition (as well as his death), she cannot yet control herself in her "New Fluttershy" form, feels guilty when she hurts somepony in that state, and she's being chased by a General Ripper version of Iron Will that wants to catch her solely to soothe his own ego.
YMMV / Harmony's Warriors
