YMMV: Ultra Fast Pony
- Cliché Storm: In "The Longest Wedding", DJ 3-Pones hands out well-worn truisms ("With the power of friendship, anything is possible!") like they're cheap cigars.
- Ear Worm:
- Ensemble Darkhorse: The Orb has become really popular among the viewers. "The Longest Recap" even lampshades it, with Sweetie Belle wondering how the heck the Orb became so popular.
- Fandom Rivalry:
- Hilarious in Hindsight:
Cadance: The power of love will fill all plot holes!
- "The Canon Has Misfired", released August 2012: Twilight asks Rarity for a stealth mission outfit, and Rarity volunteers a gimp suit. "Magic Duel", broadcast November 2012: Rarity's "dangerous mission outfit" for Fluttershy is a black, hooded suit with gratuitous bunny ears and no holes for Fluttershy's wings. Coincidence? ...Probably.
- Episode 2, "Fillen' Dem Plot Holes, Bro!" includes one caption: "I miss the days when plot hole meant something different" (i.e. the days before "plot" was slang for "pony butt"). Much later, "The Longest Wedding" featured the exchange:
Shining Armor: Yes, Cadance! Fill my plot hole with love!
- When "Hippocritic Oafs" introduces Blue Twilight, Wacarb jokes that he's got 2/5ths of a set of Twilight Rangers. Then canon completed the set by introducing Sunset Shimmer, Starlight Glimmer, and Moondancer—aka Orange Twilight, Pink Twilight, and Yellow Twilight.
- In "Faith to Faith", Pinkie "makes LittleKuriboh proud" by quoting "Shut up and take my money!". While everyone else finds it hilarious, Applejack thinks it's a comedic copout. The next two episodes ("Reading to Rainbow" and "Pirate Shipping") both featured stingers involving scenes redubbed with Futurama audio.
- "The Cheesen One" (released September 2013) suggests that cheese is important to Rainbow Dash, since it figured prominently in her mother's Final Speech: "Life is like a wheel of cheese... and you have to eat the cheese before it gets moldy." In "Pinkie Pride" (released February 2014), a giant cheese wheel features in Rainbow Dash's birth-iversary celebration.
- "Stranger Than Fan Fiction" introduced "Yellow Twilight" who was represented by footage of a yellow pony toy, and who wrote a Self-Insert Fic where Purple Twilight has a crush on her. Then in "Amending Fences" Moondancer, (an unseen pony mentioned in episode one) was finally revealed to look just like Twilight, but with a yellow coat. And Moondancer's behavior was surprisingly consistent with the interpretation that she used to have a crush on Twilight.
- The Woobie: Poor Soarin.
- Also, pretty much the entire main cast
