While she is taunting, Female Byleth has slightly different animations. This does not change her hitboxes, though.

  • Up Taunt: Male Byleth swings the Sword of the Creator outward and holds it to his side while raising his left hand to his chest and looking upwards, while female Byleth swings the sword behind her and holds it in a reverse grip while placing her hand over her chest. Based on Byleth's victory animation while wielding a sword
  • Side Taunt: Holds the Sword and the Creator in front of them while saying, "Let the lesson begin!" or "Stay focused." The first quote is one of their lines used when activating a critical hit, while the latter is based off their quote when selected as a unit.
  • Down Taunt: Spins the Sword of the Creator in whip form in front while saying "Try me!"

On-Screen Appearance

  • Warps onto the stage with a pointer before replacing it with the Sword of the Creator.

Idle Poses

  • Swings the Sword of the Creator in a reverse grip before holding it out in front of them. Based on their animation when selected as a unit.

Victory Poses

  • Plants the Sword of the Creator into the ground alongside the other Hero's Relics already planted, and walks forward saying "Each battle, a chance to grow" before swinging out their left arm and lowering it while facing the background. Combines the game over screen of Three Houses with Byleth's quote after defeating an enemy.

The following victory poses differ based on the gender selected.


  • Swings the Sword of the Creator outward and holds it to his side saying "Allow me to demonstrate!" while raising his left hand towards his chest and looking upwards. Based on Byleth's victory animation while wielding a sword, with the quote deriving from one of his critical hit quotes.
  • Opens his eyes and takes the Sword of the Creator from his shoulder and swings it at the ground in front of him while in whip form saying "No hesitation!" before returning it to its normal form and holding it out in front of him. The quote originates from one of his lines upon activating a critical hit.


Female Byleth has slightly different animations from her male counterpart.

  • In the first victory animation, she swings the Sword of the Creator behind her and holds it in a reverse grip before he places her hand over her chest saying "Allow me to demonstrate!". Unlike Male Byleth, she looks toward the screen.
  • Swings the Sword of the Creator twice in whip form before holding it vertically close to her saying "No hesitation!"

In competitive play

Due to being released during the time when the COVID-19 pandemic shut down offline tournaments and forced everything online, Byleth's intial receptions came from the latter, which their poor frame data, slow overall speed, limited landing options and struggling against faster characters (like Sonic) caused them to be placed at low tier, even when they were buffed and the success MKLeo and Pelupelu had with them.

That said, Mkleo still believed that Byleth had what it takes to be high tier and continued playing them offline, achieving results rivalling his pre-pandemic Joker's, causing perception to shift towards them being mid tier. Since MKleo is still their only good representative, their viability is still up for debate.

Classic Mode: A Heroic Legacy

Byleth's Classic Mode route is themed around the Fire Emblem fighters and stages from across the Smash series, fought in order of release year. All battles are stamina battles and the player always starts with 100 HP.

  • Byleth's code name within the game's files is "master", a reference to their role as Professor in Three Houses.
  • Byleth is the only fighter to have two splash arts, which is due to the Japanese version of Byleth having two names for each gender.
    • It is also due to this difference of names that both genders of Byleth are shown together in advertisements and other promotional material for the Fighters Pass.
    • Female Byleth's Splash art states that she was recruited by the male Byleth himself.
  • Byleth is the fifth fighter to receive an invitation in their trailer, following Villager, Isabelle, Joker, and Terry.
  • Byleth is the only character in the Fighters Pass to originate from a second-party series.
  • Byleth is the third character from the Fire Emblem universe:
    • To be added as DLC following Roy and Corrin, but the first one to come with a stage.
      • Much like Roy and Corrin, Byleth also comes from a game that released after a Smash title, as Three Houses came out 7 months after Ultimate.
        • This also makes Byleth the most recently-released fighter in the game, and by extension the entire Smash series.
    • To be playable as both male and female, after Robin and Corrin.
      • They are also the sixth overall with this distinction, following Robin, Corrin, Villager, Pokemon Trainer, Wii Fit Trainer, and Inkling.
      • Unlike the other Fire Emblem characters to be playable as both male and female, Byleth has two appearances per gender that match canon appearances.
  • Much like Ike, Inklings, Pokemon Trainer, and Wii Fit Trainer, both genders of Byleth will have different animations. This can be seen with their idle animations and victory screens.
  • When K.O.'d, male Byleth may shout "Not my best!", while female Byleth may say, "Forgive me!", being one of the few characters to say something while KO'd.
    • Byleth is also one of four characters in the Fighters Pass to do so, the others being Joker, Terry, and Min Min
  • When Star KO'd, Byleth screams, "My battle ends here!", being the second character to do so following Pit.
  • Byleth currently has the shortest wait time between announcement and release, being two weeks.
    • This was not the case in Korea, oddly enough, as the reveal was delayed to January 22 as opposed to January 16 with the rest of the regions.
