Ending the Rekka series on a successful hit will knock the opponent down.
Graviert WürdeGuardAllStartup35Recovery(72T)Advantage+11 ([4]6S/H) is a multi-hitting projectile that can nullify other projectiles in neutral. The S version is used as a quick move to check the opponent while the H version is used for pressure after knockdowns due to its longer active frames and slower startup.
Brynhildr Stance (aka Backturn)

Getting into Bryhnildr StanceGuardStartupRecovery12TAdvantage- is Leo's main win condition.

In backturn, Leo cannot block or jump, but all all of his buttons become more threatening with distinct uses in pressure, while maintaining access to all of his regular specials as well as some backturn-only specials. He can get into Backturn by crossing over the opponent with 236H, from ground throw, by holding H while using 5H or 6H, or from hitting with j.236H.

bt.PGuardMidStartup7Recovery12Advantage-2 is both throw invincible and upper body invincible, making it easy to hit confirm or anti-air off of.
bt.KGuardLowStartup5Recovery7Advantage+2 is throw invincible and Leo's fastest low. Easy to hit confirm from.
bt.SGuardMidStartup6Recovery14Advantage-1 is a great combo starter in the event of a CH, and is easily special/super canceled into a knockdown or air combo looping back into stance.
bt.HGuardHighStartup18Recovery9Advantage+6 is a plus on block overhead that Leo can reliably combo from on hit for massive damage.

It also reflects projectiles.
bt.214SGuardAllStartup14Recovery21Advantage-7 is the standalone version of Leo's rekka ender, with greater properties on air hit or counterhit.
bt.214HGuardHigh*Startup27Recovery29Advantage+36~+3 (Stagger) is a slow overhead that bounces the opponent into the air on hit. On block, it staggers the opponent for massive frame advantage.
bt.632146SGuardAllStartup5+(104)+0Recovery24Advantage+8 is one of the fastest supers in the game, being frame 5 startup with 0 frames of post-superflash startup, meaning if the opponent is close to Leo and isn't blocking, they're getting hit. A staple in corner combos as it launches and deals massive damage, all while being plus on block.

Combos

Leo's combo goal is to knock the opponent down and transition into backturn whenever possible.

5K > c.S > (f.Sonly combos into the following move against crouching opponents) > 236S > 236H > 214S is a very basic hit confirm This keyword does not have an entry in the Glossary into a knockdown.
... > c.S (Air hit) > jump cancel (jc) j.K > j.S(1) > jc j.K > j.H > j.236H is Leo's standard air combo route that leads into Bryhnildr StanceGuardStartupRecovery12TAdvantage- with frame advantage for strong pressure
bt.K > bt.P > bt.K > bt.S > Rekka series is a standard backturned low confirm into knockdown
bt.H > bt.S > Rekka series is a standard bt.H confirm against a crouching opponent into knockdown

Starting combos

5K is a very reliable starter for most situations.
f.S can combo into 6K against crouching opponents which allows Leo to get closer for stronger combos at a range where he normally has trouble converting.
Counterhit 2HGuardMidStartup10Recovery26Advantage-15 or bt.632146SGuardAllStartup5+(104)+0Recovery24Advantage+8 in the corner launch the opponent very high for strong combos.
Spending Meter
[4]6S YRCYellow Roman Cancel is a good way to try to approach in Neutral as the projectile covers the opponent's movement options while slowing the screen to react to what the opponent is doing.
Leo can RRCRed Roman Cancel any move that launches a grounded opponent into order to convert into an air combo ending in j.236H for Backturn pressure (ex. Rekka series > RRC > 5K > c.S > jump cancel > ...)
bt.632146S can be confirmed into from a bt.H hit from anywhere on the screen. In the corner, this serves as a very high damage launcher in Leo's most damaging combo routes.
On block, bt.214H deals a lot of chip damage and puts opponents into a stagger state. RRCing this move allows it to act as an unblockable combo starter, though the combo damage scales heavily.

Reversals

[2]8HGuardMidStartup8Recovery30+12 after landingAdvantage-54 is a charge anti-air akin to Flash Kick that can be used to knockdown an opponent and start Leo's pressure (albiet he does not transition into Bryhnildr StanceGuardStartupRecovery12TAdvantage- very easily before the opponent wakes up). It is Leo's primary meterless reversal. The S version should be used as an anti-air, while the H version is better used to get out of pressure. You can also RRCRed Roman Cancel the first two hits of the H version to keep it safe.
632146HGuardMidStartup10+(40)+1Recovery28+13 after landingAdvantage-18 can be used to blow through projectiles and is burst safe in the corner for the cost of 50 Tension. The best part is that if Leo holds [H] while the super ends, he transitions into Backturn.
Although not a reversal in the traditional sense, bt.DGuardUnbStartupRecovery37TAdvantage- is completely invincible to everything but throws and is used to counter mashing with a parry that can lead to solid damage, especially in the corner where it wall sticks.

Okizeme

What to do after a knockdown

Leo wants to either set up a meaty Hitting an opponent to cover the moment as they lose invincibility. The most common one is performing an attack early on okizeme to gain frame advantage and bait reversals. projectile with [4]6H or get into Backturn stance.

When neither is possible, Leo can use a well-timed 6K as a throw invulnerable meaty to hit the opponent's wakeup, staggering them and leading into a combo if they pressed a button or attempted to throw.

Backturn Setup

Next to a downed opponent, Leo can have enough time to 5[H] or 6[H] to enter backturnGuardStartupRecovery12TAdvantage-. Against lengthier knockdowns (such as from a rekka series), you usually have enough time to raw 236H. While in backturnGuardStartupRecovery12TAdvantage-, use basically anything on their wakeup - bt.H for a plus on block overhead, bt.P and bt.K are throw invincible, and bt.S has a disjointed hitboxGuardMidStartup6Recovery14Advantage-1 to beat mash attempts and score a rewarding counterhit. When the opponent respects all those options, backturned forward dash can actually crossup Attacking your opponent after changing which horizontal side you are on, typically by jumping over them. the opponent for left/right mixups.

These backturned mixup options are also very reliably accessed from a Ground Throw, since Leo is extremely advantaged and is automatically placed into Stance.

Projectile

[4]6H before they wake up. Time your YRCYellow Roman Cancel so Leo can act right as the projectile begins to travel for massive frame advantage. Midscreen, Leo may need to dash to secure a meaty projectile. If you transition from charging with [4] to double tapping the opposite direction quickly enough, you can have Leo slide forward from his stepdash and still throw his move out. In the corner, No dash is needed since the Projectile will already be on top of the opponent.
Note that Leo cannot cancel into special moves from his 2DGuardLowStartup12Recovery16Advantage-5, as such, the projectile must be timed after he finishes recovering.

While the opponent is locked down and forced to block thanks to the projectile, Leo can go for a High/Low mixup. Example from a 2D > [4]6H > YRC > forward jump in the corner:

Land 2K (Low)
Airdash right before landing and j.K or j.S (High)
