- Celica has been confirmed per Tokyo Game Show 2017.
- No word on amiibo compatibility yet, but Marth has been confirmed.
- Jossed, Ike, Roy, and Alm do not appear in the game, and interviews indicate that Ike and Roy will likely not appear until an eventual sequel.
- Jossed.
- Jossed.
- Jossed.
- Confirmed!
- Possibly confirmed? The winner of the women's division, Lyn, was the first character revealed not to originate from Archanea or the 3DS games.
- Basically jossed. Of the four poll winners, only Lucina has a major role; Lyn doesn't appear in the story and Ike and Roy are no-shows.
- Ryoma and Xander confirmed, as per the E3 2017 game trailer.
- If Sakura and Elise will be playable, they'll be a bow user and a tome user, respectively.
- Camilla, Leo, Hinoka, and Takumi have all been revealed as per the Gamescom 2017 trailer, leaving just Sakura and Elise to be confirmed or not. The trailer does, however, state that both Nohrian and Hoshidan royalty are searching for their missing siblings.
- Elise confirmed on September 1, with Sakura possibly coming in Famitsu.
- Sakura confirmed in Famitsu on September.
- In short, all are confirmed, with Azura as DLC.
- Not happening unless we get a second wave of DLC. We've gotten an outline of the season pass and it's one pack for each of those three games. The Fates one has strongly hinted that Azura (who is conspicuously absent from the base game) will be the character.
- Jossed.
- Young Tiki confirmed at Tokyo Game Show 2017.
- They're also the two most popular male heroes according to the Fire Emblem Heroes popularity poll, leaving them out wouldn't be the best idea.
- Jossed.
- Confirmed!
- Jossed.
- Jossed.
- Confirmed!
- Jossed.
- Jossed, although Gharnef does appear as a minor Arc Villain.
And as Fire Emblem Lore goes, there are 5 gems in the Shield, and I'm assuming each Game world will supply one of the gems. We already have Awakening, Fates, and the Archenea games present, but that leaves 2 stones w/o a world to visit to get them.
Thus, we basically have 2 worlds that still have yet to be represented (so, Valentia, Jugdral, Elibe, and Tellius are still fair game).
- As much as I'd like this... the original E3 trailer had the five orbs with Falchion, Falchion, Yato, Siegfried and Raijinto. Here's hoping your explanation sticks!
- Sort of confirmed; Celica and Lyn are playable, but not in story mode. As for the Shield of flame, the orbs are lit up by the presence of Marth, Chrom, Corrin, Ryoma, and Xander.
- Just Like Hyrule Warriors, there will be several levels of weapon quality ranging from the weakest but readily available to the legendary but extremely rare.
- There might be a standard-class line of Weaponry.
- Bronze Weapons: Introduced in Radiant Dawn as the weakest standard-class of weaponry. All characters in Fire Emblem: Warriors start off with a Bronze Weapon.
- Iron Weapons: This was the weakest class of weaponry since the very beginning of the Fire Emblem series until Bronze Weapons appeared.
- Steel Weapons: A step up from Iron Weapons but still not good enough in most cases.
- Silver Weapons: The best standard-class of regular weapons. They're only outmatched by the Legendary Weapons.
- Legendary Weapons: The very best standard-class of weaponry available. They also fetch a high price on the market but the chances of getting one from a random-drop are the lowest.
- Glass Weapons: Introduced in Fire Emblem: New Mystery of the Emblem, these weapons have the Attack Power of Silver Weapons but have a durability mechanic that causes them to become as weak as Bronze Weapons after being used a certain number of times. They're something of an alternative for characters that can't use Silver Weapons yet.
- Wooden Weapons: Joke weapons that only have 60-80% Attack Power compared to Bronze Weapons. They're almost worthless for anything except the comedic value that comes from humiliating stronger opponents with what is perhaps the weakest class of weaponry in the game.
- And specialized-classes of weaponry.
- Slim Weapons: Very fast Movement and Attack Speed but Attack Power is exceedingly weak.
- Devil Weapons: They could operate on a "Trade-off Mechanic" such as "slowly draining the user's life to increase attack power" or "increasing your attack power and lowering your defense". Use at your own risk!
- Weapon wise the Bronze, Iron, Steel, Silver, and Legendary Weapons, though they work differently than the editor suggested, are Confirmed. The rest are Jossed.
- Confirmed. All four NPCs are DLC along with Minerva, Linde, Olivia, Tharja, and Azura.
- Jossed by DLC Pack 1. Anna does not get anything new from it, meaning unless she gets one for Pack 2, she will not be getting one.
- The Tellius games, Path of Radiance and Radiant Dawn
- Fire Emblem: The Binding Blade
- The upcoming Fire Emblem Switch game (in which case this pack would be released on the same day or after the main series game).
- Swimsuits for the five main Lords, the twins, Anna, the other Fates siblings and probably a few of the other girls.
- A History Mode on a beach with a more lighthearted and funnier plot than the other History maps.
- Joke Weapons.
- Jugdral Pack, containing characters from Genealogy of the Holy War: Sigurd, Arden, Seliph and Julia.
- Elibe Pack, containing characters from The Blazing Blade: Eliwood, Hector, Matthew and Rebecca.
- Tellius Pack, containing characters from Path of Radiance and Radiant Dawn: Ike, Titania, Soren and Micaiah.
- Valentia Pack, containing characters from Fire Emblem Gaiden and its remake: Alm, Mathilda, Saber and Mae.
- Robin and Anna's weapons in the Fates pack, as Thoron became Robin's personal weapon in Fates and Anna's bow debut in that game. All Fates characters already have a personal weapon, so this balances it out.
- Jossed. Anna and Robin do not get a unique weapon with the Fates pack.
- Caeda and Tiki's weapons in the Shadow Dragon Pack.
- Lissa, Frederick, and Cordelia's weapons in the Awakening pack.
- Sort of confirmed. Azura's map takes place before the route split, Oboro's map is based on a Birthright level, and Niles's map is based on a Conquest level.
- Conquest Chapter 10: Unhappy Reunion or Conquest Chapter 23: Possessed
- Birthright Chapter 18: Leo
- Revelations Chapter 6: Into the Ground (With Frederick replacing Gunter)
- Jossed for all three Fates chapters.
- Chapter 3: A Brush in the Teeth (With Lissa replacing Lena)
- Confirmed, but Sakura is the one playing as Lena.
- Chapter 10: Princess Minerva (With Elise replacing Maria)
- Confirmed, but Lissa is the one playing Maria's role.
- Chapter 11: Knorda Market
- Confirmed.
- Chapter 9: Emmeryn (With Yelena replacing Emmeryn)
- Confirmed as Tharja's map but Jossed for anyone playing Emmeryn.
- Chapter 11: Mad King Gangrel (With Darios replacing Gangrel)
- Confirmed, but it's renamed as to focus more on Olivia instead (Caravan Dancer).
- Paralogue 5: Scion of Legend
- Confirmed.
- Minerva: Will use Camilla's base moveset but with special attacks involving Iote's shield. She will wield the Hauteclere from the DS remakes as her signature weapon. The Whitewings will be referenced.
- Alternatively Minerva will have Iote's shield as a Crest skill that will involve making the character take reduced damage from Weapon Triangle or Special Weapons, such as Corrin being weak to Dragon slayer weapons.
- Semi-confirmed. Minerva does have Iote's Shield as her Crest Skill, but it reduces effective damage taken.
- Navarre: Has Lyn's basic moveset and the Mercurius as his ultimate weapon. If the Mercurius isn't included, the Master Sword will be one of his weapons.
- Jossed for his personal weapon, it's the Wo Dao.
- Owain: Potentially use Ryoma's moveset or a new one. One of his specials will be the attack he used during his introduction into Warriors, while his signature weapon will be the Missiletainn.
- Tharja: Either has Robin's basic moveset, or a unique one revolving around different dark spells from the game. One of her specials will end with her giving a Yandere expression in some manner.
- Oboro: Will have the same moveset as her NPC self and the unplayable Soldiers/Halberdiers by extension. However playable Oboro's moveset will be expanded and improved. The Bolt Naginata will be used for an attack.
- Her Crest skill could be either Rend Heaven, which will increase her damage based on Magic or Attack, or Quintoxic, which will boost the skill activate rate of skills.
- Semi Jossed. She doesn't use the Bolt Naginata but instead makes her spear larger for her specials, while her Crest Skill isn't Rend Heaven or Quintoxic, but Counter.
- Azura: Will have an original moveset involving her powers as a songstress, potentially even having her default strong attack being her sing something that buffs nearby allies. Her weapons will include the Blessed Lance and the Azura Lance of Fire Emblem Heroes.
- Confirmed. Azura's default strong attack is a dance that buffs allies and she has the Blessed Lance.
- Assuming the DLC characters can even have conversations with preexisting characters in the first place (or conversations at all). But, given this game gave the canonical aunt and niece, Lissa and Lucina, a conversation, it’d be eyebrow-raising if the, likewise, canonical uncle and nephew a conversation were not given the same treatment.
- Confirmed!
- Anna’s Bow
- Confirmed, the weapon is obtained on the Knorda Market map (Linde's map).
- Oboro’s Spear
- Confirmed, the weapon is obtained on the History Mode map that is based around Oboro (Land of Gods).
- Blessed Lance (for Azura)
- Confirmed! She starts with it.
- Niles’ Bow
- Confirmed, the weapon is obtained on the History Mode map based around Niles (Cold Reception).
- Wing Spear (For Caeda)
- Confirmed, it's found on the A Brush In The Teeth map.
- Divinestone (For Tiki)
- Confirmed, it's found on the Princess Minerva map.
- Wo Dao (for Navarre)
- Confirmed, the weapon is obtained on the History Mode map based around Navarre (A Brush In The Teeth).
- Aura (For Linde)
- Confirmed. She starts with it.
- Hauteclare (for Minerva)
- Confirmed. She starts with it.
- Thoron (For Robin)
- Confirmed!
- Healing Axe (For Lissa)
- Jossed. It's a new and original weapon (Lissa's Axe).
- Armored Axe (For Frederick)
- Jossed, it's a new and original weapon (Frederick's Axe).
- Gungnir (For Cordelia)
- It seemingly was intended to be her personal weapon, but Jossed. She has a new and original weapon (Cordelia's Spear).
- Missiletainn (For Owain)
- Confirmed.
- Nosferatu (For Tharja)
- Jossed, it's a new and original weapon (Tharja's Hex).
- I’m not sure for Olivia. Maybe a new weapon like Dancing Blade.
- New theory. Balmung. The model was reused for her son, Laslow's Blade in Fates.
- Olivia's weapon is actually a new and completely original sword.
- Minerva x Celica: Talking about what dedicated vassals the Whitewings are, and Celica thanking Minerva for “lending” their service.
- Jossed.
- Linde x Cordelia: Asking each other for advice on overcoming their unrequited crushes on Merric and Chrom respectively, as well as commenting on how their voices sound so similar.
- Jossed.
- Navarre x Lyn: Navarre’s history of working with bandits causing uneasiness for Lyn, whose parents were killed by bandits.
- Confirmed.
- Owain x Leo: Call-Forward to Owain’s future status as Leo’s retainer, under the Odin alias.
- Confirmed.
- Olivia x Sakura: Constantly stuttering to each other as they struggle with their words.
- Confirmed.
- With the first DLC Pack adding a few alternate costume's, and the option to have both Corrin's wear either Promotion costume, this has strong chances of coming true.
- Jossed.
- Jossed, it's a Groom costume.
- Confirmed for the Wing Spear part!
- Confirmed. But instead of just going up the less HP you have, it gives you a great boost in attack power but drains your life in the process.
- Jossed, no one plays Emmeryn's role.
- Confirmed!
- Jossed. It has been announced that the Awakening pack will be the last DLC for this game.
The Genealogy remake possibility aside, Three Houses are one of the most lauded games and it's taking notes from Genealogy. It would make a lot of sense if both of them are lumped together, since they are both in Fire Emblem' darkest settings. If we consider Rowan and Lianna's adventures to be more typical 'friendship bond prevails' adventure, then the new Warriors will be a darker take, which naturally would give way for the darker entries of the game. Tailing behind them are the Tellius games, possibly the third darkest behind Fodlan and Jugdral.
In comparison with the first Warriors game:
- Shadow Dragon -> Genealogy of the Holy War/Thracia 776
- Awakening -> Path of Radiance/Radiant Dawn
- Fates -> Three Houses
As the bonuses, most likely it would take the last two unused series: Binding Blade and Sacred Stones (I'm guessing that it would be represented by just their main Lord).
- Shadow Dragon is the first game.
- Blazing Blade is the first game in the West.
- Awakening is arguably the most popular game in the franchise.
- Fates is the best selling game.
Gaiden in Warriors does not seem to be based on Echoes aside from Celica's character design and voice actors. Celica's special moves and History Mode map are more based on the original game rather than the remake. And an outside game would probably not be known to a third party developer. I think one of the heads of the game loved Gaiden and/or Celica and wanted to put her in. The fact that a remake came out was a coincidence.
As said in the Trivia page, Azura was initally going to be in the base game, but was cut early, so as to avoid over-representation of Fates characters. However, I assume she was originally going to appear in Chapter 12 or 13, with what happens in both of them having opportunities for her to appear.
In Chapter 12, the younger brothers and older sisters are arguing and were about to fight until they realise that none of them have not even seen Corrin and someone might be setting up the Hoshidans and Nohrians to fight. Azura could've appeared here to help stop the Hoshidan and Nohrian siblings arguing and almost fighting through her connections to both of them and most likely having been with Corrin before she suddenly disappeared, then rallied everyone to stop Ryoma and Xander from killing each other along with stating she knows the whereabouts of Corrin and thus, leading them to the area where the group would discover who was goading Hoshido and Nohr to fight one another.
In Chapter 13, Corrin, Xander and Ryoma snap out of their trances suddenly, seemingly only because Iago was too hurt or distracted long enough by everyone else to keep the hypnosis up. Azura would've definitely sang her song to all 3 of them to bring them back to normal, which would've reference how she did so to snap Corrin out of their rampage before the route split in Fates or Takumi from his hypnosis in Birthright.
I believe Chapter 13 would be more likely, since her singing to Corrin, Ryoma and Xander would've been a Mythology Gag, which this game is filled with and give good reason as to why the 3 Lords snap out of their trances.
