In the sequel, the plot would most likely involve the Changelings, and/or the Crystal Empire.
- A civil war breaks out among the Changelings, and Equestria eventually has to intervene. Mirage Squadron is mobilized to help give the rebels a fighting chance against Chrysalis.
- The remnants of Chrysalis' army attack the Crystal Empire, allied with die-hard griffins who refused to accept peace. Mirage is once again called to the front, but the Crystal Empire may have some great fliers of its own...
- Partially confirmed: one of major settings of the story will be The Crystal Empire, but the Changelings will not appear at all.
- Interestingly, Word of God has implied that Changelings' attack on Canterlot will get a Continuity Nod...which leads to the question of why they won't be showing up in the sequel.
Why the Changelings are completely absent in the sequel.
- One explanation is that they simply turned tail and ran after their defeat at Canterlot, fearing Celestia and Luna would want revenge.
- A darker possibility is that the changelings were largely—or even completely—killed when they got thrown out of town, by the sheer force of Shining's shield, and being separated and scattered in hostile territory.
- Jossed. They are scattered in the Badlands and still attempt to reorganize their society.
The Reapers will suffer Death by Irony
, based on their defining traits.
- Deathwing: He wants to only fight the best of the best, so perhaps he'll be overly focused on killing Mirage, or perhaps just Rainbow Dash...which will leave him open to a lethal cheap-shot by an Equestrian Red Shirt / Mauve Shirt / the rest of Mirage Squadron.
- Shockwave: His cold, logical mindset will bite him in the flank when he ends up facing a truly unpredictable foe—Possibly Derpy, or even Pinkie Pie.
- Havoc: He'll lose his cool in battle (Exiles suffer a particularly nasty defeat? Death of one of the other Reapers?) and drop his laid-back nature. This gets him killed in a moment of carelessness.
- Trickster: Sort of a mirror to Shockwave—he'll face an opponent who simply ignores his taunts, and counters his wild fighting style with cool efficiency. Likely candidates are Firefly, Rainbow Dash, and Fluttershy (in Tranquil Fury).
- The Exiles must have built up a colony or base of some sort during their, ahem, exile. Given the amount of labor and infrastructure it would take to construct the full fleet of warships they used to attack Fillydelphia in chapter 3 (not to mention crew them), it's likely that their population is quite large, and that not all Exiles are part of Aurora's army.
- Hinted to be true in chapter 4.
- Given the sequel's Darker and Edgier direction, this might be possible. With the aversion of Infant Immortality, brutality towards civilians by the Exiles so far, and the history Aurora and Celestia have with each other...things may get VERY ugly when Equestria goes on the offensive.
- Especially with the aforementioned hint of a non-combatant Exile population in Chapter 4; we'll have to wait and see where that ultimately goes.
