- Accidental Aesop: Learning at a slower pace does not mean you aren't smart, strong, or capable. Also, there is a right and a wrong way to encourage someone who's struggling.
- Alternate Character Interpretation:
- Were the claims that Starswirl disappeared before Luna's banishment at odds with "Reflections", where he was shown to be around afterwards? Or were those who claimed such lying about it to hide the incident, which all involvednote agreed never to speak of again?
- Was younger Celestia's personalty contradictory with what The Journal of the Two Sisters portrayed? Or did the biases of the authors (Celestia and Luna) prevent this from coming up. Did Celestia only become like this after the events Journal covered?
- Base-Breaking Character: Celestia, as soon as previews for the first issue showed her as arrogant and stuck-up as she disrespects Star Swirl and lords her superior magic over Luna. Some welcome the depiction for the thematic parallels to Sunset Shimmer and showing that Celestia had to go through her own maturation and Character Development. Others object for not fitting prior continuity from The Journal of the Two Sisters (which suggests Celestia was nothing like this at the time) and pandering to the Ron the Death Eater mindset of Celestia's detractors.
- Fridge Brilliance:
- Starlight Glimmer's annoyance about Sunburst not spending time with her make much more sense upon realizing the comic takes place during the events of "Uncommon Bond".
- The ending has Sunburst compare Stygian to Twilight Sparkle, who fans assumed was Star Swirl's counterpart. This would leave Starlight Glimmer as Star Swirl's counterpart, which make a lot of sense in retrospect. Both were magical prodigies with antisocial tendencies, hard-line beliefs, and used magical fixes that created new problems. Starlight's Spotlight-Stealing Squad status in "Shadow Play" as the Only Sane Woman now has justification; Star Swirl was their Shadow Archetype and Starlight had to stop them from making the same mistakes the old her would have.
- Relatedly, Stygian is Twilight Sparkle's Shadow Archetype. Both's Fatal Flaw was their admiration for Star Swirl kept them from speaking out against him. But Starlight, due to Twilight's teachings, convinced Twilight to act up when she knew him wrong, thereby undoing both Star Swirl and Stygian's mistakes.
- Fridge Horror: In the Annual, the alternate Pony of Shadows says their Star Swirl stopped then from corrupting their versions of Celestia and Luna. How? Given that the Pony of Shadows has to resort to using the Princess alternate counterparts despite controlling the world, the apocalyptic consequences if he succeeded, and Star Swirls excessive habit of Shoot the Dog...
- Hilarious in Hindsight: Issue #2 seems to predict Thor's fate.
- Idiot Plot: Rockhoof is egged on by his friends to party and eat in his story. None of them, especially Rockhoof, realize the damage he's doing to his health until the volcano shows signs of eruption.
- Writer Jeremy Whitley received some criticism for ignoring continuity with The Journal of the Two Sisters despite using it in his prior work. Turns out Legends was written to match continuity with "Shadow Play", which is what made Journal Canon Discontinuity.
- Rockhoof calling Flash Magnus "Flash Sentry" was bombasted as a typo by careless writers, despite Rockhoof having been shown◊ to have trouble remembering Flash's name.
