History Characters / FireEmblemThreeHousesByleth

* ExtremeOmnivore: They'll eat anything edible. It's to the point that in ''Three Hopes'' [[spoiler:as a playable character, they have no disliked dishes whatsoever]].

* {{Irony}}: Their nickname is "Ashen ''Demon''" but they can end up fighting on the side of the [[spoiler:Church of Seiros on the Silver Snow route and marry Rhea]]. They can also end up becoming [[spoiler: the next archbishop of the Church of Seiros at the end of the Azure Moon route]].

* {{Irony}}: Their nickname is "Ashen ''Demon''" but they can end up becoming [[spoiler: the next archbishop of the Church of Seiros at the end of the Azure Moon route]].

* LikesOlderWomen: Male Byleth is [[spoiler:twenty years old]] at the start of the story and can potentially marry Manuela, who is 36 years old, or Catherine, who is 32 years old by the end of the story. Downplayed if either version of Byleth marries Mercedes, who is 27 by the end of the story, meaning that, depending on whether [[spoiler:the five years Byleth spent in a coma]] count or not, she is either two or five years older than Byleth. Exaggerated if either version of Byleth marries Rhea who is at least a [[spoiler:''[[Really700YearsOld millennia]]'']] older than them.

** In Bernadetta and [[spoiler:Jeritza's]] supports, they're sympathetic to the horrors the two have suffered at the hands of their abusive fathers, and regard said fathers as utterly despicable for what they've done.

** On the Crimson Flower route, it's Edelgard's ideals and ambitions for Fódlan's future that drive the plot, and Byleth mostly exists as an enforcer and MoralityChain. And incidentally, [[spoiler:this is the only route in which Byleth doesn't end the story in some position of leadership. In Azure Moon, Rhea steps down and Byleth becomes the Archbishop of the church, and in Silver Snow and Verdant Wind, Byleth becomes the leader of the united Fódlan (with Claude returning to his home country in the latter). In Crimson Flower, Byleth ends the story as Edelgard's right hand.]]

* TheAce: They were a mercenary before becoming a teacher at the Officers Academy, yet is skilled enough to teach the continent's most elite. After the timeskip, their allegiance alone decides the fate of the war. In their B-Support [[MasterSwordswoman Catherine]] even notes that someone with all their good qualities shouldn't logically exist, and yet here they are.

* ReiAyanamiExpy: Both versions of Byleth fall under most of the criteria of one. Byleth has pale skin, short dark teal/light green hair ([[spoiler:after merging with Sothis]]) and is implied to be in their early twenties. Byleth's [[DarkAndTroubledPast backstory is also rather tragic]] as their mother [[spoiler:died shortly after childbirth]] and they were raised by their father Jeralt to be [[ChildSoldiers a mercenary from an early age]]. Byleth is somewhat taciturn and is also noted to be very [[TheStoic stoic]] and emotionless by numerous characters but becomes [[NotSoStoic more emotional]] over the course of the story. Additionally, Byleth is revealed to be a Crest-bearer, possessing an incredibly rare Crest of Flames which allows them to [[spoiler:wield the Sword of the Creator]]. Furthermore, on every route Byleth ends up developing a strong connection with one of the lords (Claude, Dimitri, Edelgard) which can develop into a [[RelationshipUpgrade romantic relationship]].

* LikesOlderWomen: Male Byleth is [[spoiler:twenty years old]] at the start of the story and can potentially marry Manuela who is 36 years old. Exaggerated if he marries Rhea who is at least a [[spoiler:''[[Really700YearsOld millennia]]'']] older than he is.

* GameplayAndStoryIntegration:
** They grew up outside of the influence of the Church of Seiros, hence not having a particular affinity or weakness for faith at the beginning of the game, but become one of the Church's strongest knights, find out [[spoiler:that the goddess of Fódlan was implanted within them in their infancy]], and in one route [[spoiler:ends up as the new Archbishop after Rhea retires]], hence a budding talent in faith.
** Despite having the potential to be classed as a mage or MagicKnight, Byleth's Magic base stat and growth rate are barely above average. Byleth spent their life being raised by Jeralt as a ''mercenary''. Jeralt himself is a Paladin who does not use magic at all. So it makes sense that Byleth's own growth in magic is lacking compared to the students who were trained in it since a young age.
** On a similar token, while Byleth is nominally a JackOfAllTrades, being usable in potentially any class they classed in, the actual combat arts that Byleth is capable of learning favors them towards Sword- and Brawling-oriented classes. [[spoiler:It's another hint at Byleth's relation to Rhea.]]
* GameplayAndStorySegregation:
** Supports with other characters, such as Hannamen, Seteth and Felix, imply that Byleth is a seasoned warrior and MasterSwordsman, hinting that they started mercenary work at [[ChildSoldier ten at the very least]] and that they possessed renown matching their father's, with them being known and feared as "[[RedBaron The Ashen Demon]]" for their skill and emotionless visage in battle. Of course, being one of the first playable characters, Byleth starts with low stats compared to similarly renowned warriors such as Catherine, while most of their skills are at E, with their highest ones being swords at D+, brawling at E+, and Authority at D respectively.
** Divine Pulse in gameplay in ''Three Hopes'' allows Byleth to freeze time and attack enemies while the time is frozen, damage accumulating and then occuring as soon as time starts moving again. In actual cutscenes though Byleth/Sothis seems to have to make time start moving again before making contact with any attack, the time stop only being used to allow them to get close to an opponent without being noticed until the last moment.

* AllLesbiansWantKids: Downplayed. If female Byleth romances [[ChurchLady Mercedes]] on the Crimson Flower route their paired ending states that they ended up opening an orphanage and raising many kids together. Furthermore, in the Japanese version of the game female Byleth's paired ending with [[GayOption Dorothea]] states that they ended up adopting and raising many kids together.

** Inverted if a female Byleth gets a paired ending with [[spoiler:[[DefrostingIceQueen Felix]]]] on a non-Azure Moon route as the ending text strongly implies that she [[spoiler: eventually returns to her life as a mercenary together with Felix after abdicating the throne]].

** Inverted if a female Byleth gets a paired ending with [[spoiler:{{Tsundere Felix}}]] on a non-Azure Moon route as the ending text strongly implies that she [[spoiler: eventually returns to her life as a mercenary together with Felix after abdicating the throne]].

* RagsToRoyalty: Despite starting out as a humble mercenary under their father, [[spoiler:most routes have them in a position of power by the end. On Verdant Wind and Silver Snow, they're the divinely-inspired new King/Queen of the newly-united Fódlan (with a female Byleth potentially ''also'' being Almyra's Queen if she marries Claude), while on Azure Moon, they're formally made the new Archbishop of the Church of Seiros, although a female Byleth can become [[HappilyMarried Dimitri's Queen Consort]] if paired with him. Crimson Flower is the only exception - while a Byleth of either gender can marry Edelgard and be her consort, as well as some paired endings such as with Linhardt, and Ferdinand, mentioning Byleth retires in luxury and a noble title, most endings involve Byleth retiring to a peaceful and humble lifestyle with their spouse or in their solo ending, continuing their war with the Agarthans.]]

* AndTheAdventureContinues: In their Crimson Flower solo ending (and their paired ending with [[spoiler:Sothis]]), [[spoiler:they are stated to go to battle against those who slither in the dark after the war's end]].

** Byleth can also end up on the receiving end of this trope if they romance anyone on the Azure Moon route as it ends with Byleth [[spoiler:becoming the new [[GoodShepherd archbishop]] of the Church of Seiros]].
