Byleth (male:ベレト; female:ベレス,Byleth) is a character from theFire Emblem series. As the playableavatar inFire Emblem: Three Houses, Byleth's name, gender, birthday and dialogue options can be customized. Unlike fellowFire Emblem avatarsRobin andCorrin, however, Byleth has a set appearance and set voice actors, with the majority of their dialogue being from battle quotes instead of interactions with other characters.

Byleth is also the main protagonist ofThree Houses, and assumes the role of a professor to one of the three titular houses atGarreg Mach Monastery in order to guide the students through day-to-day activities and help them improve their combat skills.

Byleth debuted in theSuper Smash Bros. series as a playable character inSuper Smash Bros. Ultimate as the fifth and final character ofFighters Pass Vol. 1.

Origin[edit]

InThree Houses, Byleth Eisner is the child ofJeralt Eisner, a former knight of theChurch of Seiros, andSitri, a nun of theChurch of Seiros. Born in Imperial Year 1159, Byleth was in critical condition during their childbirth until ArchbishopRhea, at Sitri's request, took theCrest of Flames from Sitri and implanted it into Byleth in order to save the newborn. Unbeknownst to Jeralt, Rhea also did this in order to try and reawakenSothis, the goddess ofFódlan. Although Byleth survives, the Crest transplant comes at the cost of Sitri's life, as well as Byleth demonstrating abnormally minimal emotion as a child and completely lacking a heartbeat, the latter of which seemingly has no effect on their health. Byleth does not recall much of their past, and Jeralt has told them very little of their childhood.

Part I ofThree Houses' story begins with a chance encounter where Byleth and Jeralt rescueEdelgard von Hresvelg,Dimitri Alexandre Blaiddyd, andClaude von Riegan from a group of bandits, they are brought back to Garreg Mach Monastery. Upon arriving, Jeralt is reinstated as the captain of the Knights of Seiros, and Byleth is enlisted as a professor for one of the Officers' Academy's three houses: the Black Eagles led by Edelgard, the Blue Lions led by Dimitri, and the Golden Deer led by Claude. Depending on the player's decision, the story plays out differently during Part II.

Sothis is a mysterious entity who appears in Byleth's dreams, and eventually manifests in real life, although Byleth is the only one that can see her. She has lost all of her memories except her name, but possesses significant power and demonstrates this by granting Byleth access to theDivine Pulse, an ability that allows Byleth to turn back time. Eventually, after Byleth is banished to a dark realm by a mysterious group called "those who slither in the dark", Sothis learns that she is a goddess upon rediscovering her past. She subsequently fuses with Byleth, thus granting them all of her power at the cost of ceasing to appear to them after that point, except in a few select circumstances. Sothis is also the source of Byleth's Crest, the Crest of Flames, which allows them to wield theSword of the Creator effectively.

Regardless of which house they choose, at the end of Byleth's first year as a professor, Edelgard declares war on the Church of Seiros and Byleth is forced to take a side. An accident results in them falling into a coma for five years; once they awaken, they reunite with their house of choice (or the Church of Seiros, should they decide to side against Edelgard after choosing the Black Eagles) and assist their house leader in their goals: Edelgard in Crimson Flower to destroy the Church, Dimitri in Azure Moon to stop Edelgard, Claude in Verdant Wind to discover the truth behind theCrests and theHeroes' Relics, and TheChurch of Seiros in Silver Snow to stop Edelgard and Those Who Slither in the Dark.

What happens to Byleth depends on the route chosen by the player: in Silver Snow and Verdant Wind, they become the new leader of the United Kingdom of Fódlan; in Crimson Flower, Byleth devotes the rest of their life to ending Those Who Slither in the Dark and becomes a lifelong confidant to Edelgard; and in Azure Moon, Byleth becomes Archbishop after Rhea retires.

Fire Emblem Warriors: Three Hopes offers an alternate timeline where Byleth never becomes an academy teacher. While traveling as part of Jeralt's mercenary group, they are ambushed by another group of mercenaries containingShez, the main protagonist ofThree Hopes. Byleth handily wipes out the other mercenaries and is about to slay Shez in battle before Shez suddenly reawakens with newfound power. The fight ends in a draw as Byleth claims that their repelling of the opposing mercenaries to be a successful mission and leaves, after which Shez swears to get revenge against Byleth. This alternate series of events results in Byleth never meeting the students of the Officers' Academy and remaining a mercenary. Depending on choices the player makes in the game, Byleth either joins forces with Shez, sacrifices themselves to Sothis out of revenge over Shez killing Jeralt, or confronts Shez directly in a battle that leads to one of them being slain as a result.

Both versions of Byleth also appear as units the player can recruit in the crossover gameFire Emblem Heroes. Most recently,Fire Emblem Engage features male Byleth as one of the game's numerous Emblems, ethereal clones of protagonists from various otherFire Emblem games who dwell within special rings.

InSuper Smash Bros. Ultimate[edit]

As a playable character[edit]

Male and female Byleth, as they appear inSuper Smash Bros. Ultimate.

Byleth appears as anewcomer inSuper Smash Bros. Ultimate, with his inclusion being announced during aMr. Sakurai Presents presentation on January 16, 2020.^[1] He is the fifth and finalDLC character ofFighters Pass Vol. 1, and was released on January 28, 2020.^[1] Like his fellowFire Emblem avatarsRobin andCorrin, Byleth's female counterpart is also playable as anAlternate costume character.

Super Smash Bros. creatorMasahiro Sakurai played an early version ofFire Emblem: Three Houses in order to gain a better experience of how to develop Byleth forUltimate.^[1][2] Sakurai further elaborated that he did this to also ensure that Byleth's release was not delayed, and mentioned that he used this developmental process previously, notingThe Legend of Zelda: Breath of the Wild as an example.^[1]

In a subsequent interview with Famitsu on February 5, 2020, Sakurai stated that he agreed with fan criticisms regarding the amount of both sword-wielding characters andFire Emblem fighters inUltimate. However, he reiterated that he was proceeding with a plan created for him by Nintendo and not picking his own favorite characters to be added to the roster.^[2]

Sakurai said that freshness was the theme of Byleth's inclusion, asThree Houses was released only seven months afterUltimate. Due to Sakurai's aforementioned agreement with the criticism, he sought to have Byleth's moveset reference the branching storylines ofThree Houses. As a result, he decided that Byleth would not only retain theSword of the Creator, but also wield the house leaders' signatureregalia:Aymr,Areadbhar, andFailnaught.^[2]
