Overview

Byleth is a neutral focused character with tools that make them excel in the midrange. Many of Byleth's tools are disjointed and long ranged, allowing them to poke at their opponent from a safe distance. Byleth also has a projectile in their neutral special, Failnaught. While it has a bit of startup, it's strong and can be used to snipe opponents or bait options. While not particularly amazing, Byleth also has useful tools to fight up close in Nair and jab, as well as having a decent OOS option in Sword of the Creator (Up Special), but they are used more as defensive tools to get the opponent off of them.

Byleth also has a versatile, albeit strict, combo game, with Nair and Sword of the Creator being strong combo starters. This is complimented by many of Byleth's powerful combo enders such as Bair, Dair, Side Special, and up air, the latter which can also be used to juggle somewhat. Sword of the Creator can also be used offensively offstage, as it will spike opponents above 50%. This, coupled with byleth's aerials, make them great at edgeguarding.

Byleth's weaknesses come with movement and recovery. Byleth isn't very mobile, having a sluggish dash, run, and air speed, as well as having lack luster frame data. This can make positioning hard despite their disjoints. Byleth's recovery, while not bad by any means, can still be exploited as it is a tether recovery. Low movement stats in the air also hinders their ability to make it back to the stage, as well as landing from a juggle situation.

Despite their weaknesses, Byleth is capable of dealing high damage and taking early stocks with strong fundamentals and smart decision making. If a character with a strong midrange that excels with good game knowledge sounds interesting, give the Professor from Fire Emblem: Three Houses a try! Let the lesson begin!

Summary

Byleth uses large, powerful disjoints to dominate the mid-range.
Pros	Cons
Distance Demon: Byleth posseses some of the longest ranged moves in the game thanks to their sword and lance. Mid ranged combat is no problem for Byleth. Makes people explode: Most of Byleth's attacks deal a lot of damage, break shields, and kill fairly early. They also have a surprisingly varied combo game that can also lead into big damage. Strong recovery: Sword of the Creator allows Byleth to grab the ledge from incredibly long distances. It's also a hitgrab that rockets Byleth upwards and spikes on hit, making it somewhat risky to challenge directly.	Very slow: Byleth's mobility is among the worst in the game, being the proud owner of the 9th worst run speed, 9th shortest jump height, 10th shortest double jump height, and 10th slowest air speed. Their frame data also leaves much to be desired. Trouble landing: Byleth's low air speed and lack of good moves that cover below them make landing on-stage somewhat difficult. Recovery issues: Sword of the Creator is an amazing recovery move, but it's still a tether recovery, and all of the usual problems with those are present and accounted for. Byleth's low air speed and short double jump can also make getting into position to use it somewhat difficult. Difficult combos: While Byleth's combos aren't uniquely difficult, they're fairly tight, and many of their more advanced combos are either character-specific or require techniques like IDJShorthand for "Instant Double-Jump", a technique used to Double Jump as low to the ground as possible.s.

Eagle, Lion, and Deer

Byleth's aerials, smash attacks, specials each use a Hero's Relic: powerful weapons that only certain characters can wield in Three Houses. In Smash, Byleth wields four, and each are tied to a direction, with the names of the special moves being the same as each relic:

Failnaught is a bow and is used Neutral Air and Neutral Special. Failnaught has no smash attack, as there is no "Neutral Smash".

Sword of the Creator is a sword and Byleth's main weapon. It is tied to Up Air, Up Smash and Special, but is also used in all of Byleth's tilts and jab as well.

Areadbhar is a lance that is tied to Forward and Back air, Forward Smash and Side Special.

Aymr is an axe that is tied to Down Air, Down Smash, and Down Special.

Tether Wall Jump

Sword of the Creator is unique among tether recovery moves in its ability to latch on to walls. Upon doing so, Byleth is immediately pulled in, and can jump off of the wall a maximum of 3 times. The wall jump limit is independent from the ledge grab limit and the one-second period where the tether is unable to grab the ledge after Byleth lets go.

A kneeling slash with the Sword of the Creator in its whip form. For a tilt attack, it is quite slow, but it is one of Byleth's best combo starters, leading to their other tilts at lower percents, and aerials at higher percents.

It has an often overlooked property where it will always win if it clanks with any other move (unless Byleth gets hit or it's a trascendent move).

Byleth lunges forward while swinging the Sword of the Creator. Has decently fast startup, making it a useful burst option despite Byleth's poor movement. Has a sweetspot at the blade, which is a decent K.O move, however the sourspot near the hilt is extremely weak and has virtually no K.O potential.

Try not to whiff this, or have it shielded or parried, as it has high endlag and is unsafe on shield, leaving Byleth open for a punish.

Byleth lunges forward with Areadbhar, preforming a strong thrust attack. A relatively slow smash attack, it is primarily used to call out opponents approach and ledge options, which can be done at a far distance do to the sheer amount of range this move has.

F-smash can be angles up and down, with up being a little bit most powerful, while down is a strong tool for 2-framing opponents recoveries.

Byleth swings the Sword of the Creator upward, creating a flurry of attacks. Up smash is Byleth's fastest smash attack, and can be used to cover landings or punish really unsafe moves on shield or on whiff. It's also quite strong for a multi-hit option, making it a decently fast grounded K.O option in Byleth's kit.

A heavy two hit attack with Aymr. Compared to other down smashes, it is rather slow and had a lot of end lag, but makes up for it in raw strength. Byleth's down smash is one of the strongest in the game in terms of damage and knockback. While it is not very safe on shield, it does incredible shield damage, and is capable of breaking slightly damaged shields, even more so if it is charged.

Byleth's spins Failnaught in front of themselves, causing a multi-hit attack. Nair is Byleth's fastest aerial, but also their shortest ranged aerial. It is nevertheless their most versatile aerial. Due to its fast startup and multi-hit properties, it is commonly used as an OOS option, as well as being byleth's main tool to approach and combo, especially with drag downs. Nair also has a landing hitbox, which can also lead into set ups and combos.

Byleth preforms a horizontal swing with Areadbhar directly in front of them. A decent poke in neutral and offstage, Fair can be made safe if spaced and fast falled properly. The tip of the move is a much stronger sweetspot while the shaft of Areadbhar is much weaker. Fair is Byleth's safest aerial on shield, having the lowest ending and landing lag out of all of their aerials, and can autocancel from a shorthop.

A flurry of slashes in the Sword of the Creators whip from directly above Byleth. Functions similarly to up smash, but in the air. Up air is very active, so it is mainly used as a juggle tool, and the strong final hit can K.O. It can also be used in drag down set ups due to its multi-hit properties, giving Byleth deadlier set ups.

A long ranged downward swing of Aymr. Byleth's slowest but strongest aerial. In terms of raw power, it is the strongest down air in the game, and has a sweetspot that can spike. Even without the sweetspot, it is still capable of dealing heavy damage, and does massive shield damage. However, it has massive start up and endlag, in fact having some of the highest endlag of any down air in the game.

Byleth fires and arrow from Failnaught. This move acts as a chargeable projectile, making it possible to shield, jump, roll, and airdodge out of the charging animation. Byleth can also turn around to face the opposite while readying the arrow before firing.

If the button is held, Byleth will preform a much stronger shot from Failnaught that can K.O early and even break damaged shields. However, this version of Failnaught begins, Byleth is committed to doing it and cannot cancel the charge animation.

Failnaught is used mainly to mix up Byleth's movement, especially in the air by using B-Reversing and Wavebouncing. The arrow itself can be used to snipe at opponents. The fully charged version is rarely used, mostly being a shield break punish.

Fully charged Failnaught will push Byleth in the opposite direction of which way they fired if done in the air.

Byleth preforms a lunging upward slash with Areadbhar. This move has impressive horizontal and vertical range, with a sweetspot on the blade and a sourspot on the shaft. If this move is inputted like a traditional smash attack, Byleth lunges forward even more, improving the moves range.

In the air, Byleth preforms this move while doing a flip, and is substantially weaker than the grounded version. However, aerial Areadbhar covers areas where Byleth's aerials do not, and it slightly propels them forward at the cost of having high endlag.

This move is typically used for option coverage both on the ground and the air, though the air version has application in combos after Up Special. If Byleth is at the ledge, aerial Areadbhar can be used to get past ledgetrap attempts at the risk of potentially doing a regrab of the ledge.

Byleth thrusts the Sword of the Creator upward at and angle in its whip form. This move functions as a long range tether recovery that can also attach to walls for Byleth to wall jump off of. It also functions as a hit grab against opponents. If an opponent is caught by the move, Byleth shoots up to them and bounces on their head, similar to a footstool. If the opponent is over 50% after the foostool is preformed, it will become an untechable spike.

At early percents this move is extremely vital for Byleth's explosive combo game. As the foostool has only one frame of ending lag, Byleth is abled to immediately follow up with an attack such as Bair, Dair, nuetral air, and Aereadbhar depending on the percent, matchup, and DI. At higher percents above 50, up special is potent as an edgeguard tool as it gives Byleth a guaranteed spike.

Sword of the Creator is perhaps Byleth's most versatile and important move, and is a cornerstone to their gameplan.

can tether to the ledge up to 3 times
knockback of spike increases depending on distance opponent is tethered from
instantly cancels Byleth's knockback when used in the air, so can be used with good DI to survive longer

A ---painful---ly slow downward swing of Aymr. This move has a very high startup as Byleth charges power in Aymr, but has super armor as the axe starts swinging downward. Aymr has interesting properties despite its slow startup. Byleth is able to turn the move around and pass through platforms while charging the move up. If done in the air, it slightly stalls Byleth when they swing. If Aymr collides with a platform, it will create a shockwave on the ground that weakly launches surrounding opponents.

Despite Aymr's weird quirks, this move is generally not used much outside of insanely hard reads or a shield break punish.

Wraps the opponent in the Sword of the Creator, and throws them backward while spinning around twice. Byleth's strongest throw, and their main kill throw at the ledge. Can damage and launch opponents while spinning. It can also combo into dash attack for some reason in many matchups.
