The Big Bad of Fire Emblem Warriors is named Velezark in English. Velezark's name is a clever reference to almost all of the Big Bad dragons who have come before him. The root of his name, Veles, is one of the most important gods in Slavic Mythology, and his domains include magic, water, and earth. This connects him to three other dragons Idunn theMage Dragon, Anankos theSilent Dragon, and MedeustheEarth Dragon. Veles was known to be a Troll and a Jerkass who spent much of his time being a complete nuisance to Perun, another one of the top gods of the Slavic pantheon. This ties into Velezark's title of "Chaos Dragon". Furthermore, the "-ark" at the end of "Velezark" means that it's a portmanteau of "Veles" and "dark" "dark" as in Medeus (again), Loptyr, and Grima. The only two Final Boss dragons left out of the Velezark reference party are Duma and the nameless Fire Dragon from Fire Emblem: The Blazing Blade, and neither of those two were exactly evil (though they were definitely dangerous enough to need putting down) the former had good intentions that went horribly wrong at every turn, while the latter was explicitly stated to just be taking an opportunity to visit Elibe, unaware that it would be threatening the native inhabitants just by being there. So, in summary, Velezark's name is a reference to almost the entirety of the Medeus archetype (well, the dragons of the archetype, anyway) from the Fire Emblem games up to Warriors.
A more Meta-Example. The Fates DLC pack is first and a couple months ahead of the other packs. Then you remember. Two of the characters already have a partial moveset for their NPC versions, while the third is a character they wanted in the beginning. The three characters combined probably just needed some tweaking, as well as voicing the history maps, so that the DLC could start releasing as soon as possible.
When Corrin appears at the Camp, theyll say I always wanted to run a shop. This is because in Fates, they couldnt.
The Heros Challenge Update includes a bunch of Elite Weapons, with each having two slayer attributes. The Elite Sword has Mountslayer and Armorslayer. You essentially unlock a Rapier.
The fifth History Mode Map (based on Gaiden) has Lava on the map, but it is not an impassable obstacle like the original (aside from flyers). Well, as shown in the Ebony Volcano map, characters do walk on lava in this game. And that does in fact happen in the Anna mission.
Validar constantly replaces villains on History Mode maps, making him appear more often than any other villain. If you play all the maps in order, during the last one, Chrom says that Validars reign will meet its end. If there are no more DLC maps, then yes. He will stop appearing and his reign has finally ended.
The Awakening DLC map restricts the player to using the Awakening characters (except Robin and Lissa, whom play roles in the map), Celica, and Lyn (as well as the twins and Anna as usual). Odd that it has two other characters, but then you remember. Those two can be members of the shepherds...or at least Einherjar versions.
Fredrick's stat spread makes a lot of sense knowing his archetype of a crutch character; his high strength/def lends to being strong early game where characters have yet to learn the various skills that use Skl/Spd/Luk, but as others learn such skills, they'll leave him in the dust.
The Fates chapters have the second son of Hoshido/Nohr fighting the Aytolisian army after the daughters join up with them. This makes it entirely possible for Takumi/Leo to kill Hinoka/Sakura or Camilla/Elise over a misunderstanding when playing on Classic Mode.
This is mitigated slightly over the fact that playable characters here don't necessarily die, but are injured and pulled out of battle until players pay for their healing at the shrine.
It's mentioned in numerous other places and tropes why declaring the Aytolissan twins co-regents is a weak decision, but it gets worse unless they plan to marry each other, this makes inheritance beyond them a complete mess. It's mentioned that female heirs can take the crown in Aytolis, which means no matter what, both siblings are going to have a firstborn with equal claims to the throne, and if the franchise this game celebrates has taught us anything, we know exactlyhow that is going to end. Congratulations you three, you've doomed your country to civil war.
To the counter, though, it may also mitigate a succession crisis. As an example, whichever ruler has a child first, that child is the first claimant to the throne. However, should that not be feasible, (say, due to reluctance (like Rowan)), then the second-born child can be crowned without concerns of bloodline.
Just like Hyrule Warriors, for most of the characters, the materials you receive from defeating units are a significant article of clothing Ryoma's headpiece and jinbaori, Lianna's hair clip and cloak, and so on. Some are so deeply personal that they would not be parted with otherwise, such as Azura's Pendant or Anna's Purse. All the armor-type Materials like Xander's Plate Armor or Minerva's Red Armor also doesn't help to paint a lovely mental image of what's going on...
All the headgear-related Materials can be this as well, as if they've been attempting to do a Dead Hat Shot, which works most for the more conventionally hat-like Anna's Cap.
The various materials acquired from lesser enemies like Wyvern Riders and Pegasus Knights, which are more often than not actual body parts like their steed's talon and feathers. And Velezark's materials (Chaos Dragon's Barbs and Jewel) can brings a shudder as well, since he is a gigantic dragon and unlikely to have removable clothing, implying that the player just cut off chunks of his body! Granted, he caused nothing but misery for the Aytolis twins, but the gruesome aspect of it isn't helped.
