Overview

Overview

Jack-O' is a momentum-based fighter summoning Servants that fight by her side, providing her a huge variety of options to enhance both her offensive and defensive capabilities.

Jack-O' starts the round without any Servants, and must fight for an opportunity to summon them in. Her 5K, 2K, and f.S are basic pokes to create opporunities to summon, while her 2D and 5H provide long-range fast-moving strikes to threaten opponents away. She also comes with unique anti-airs like 6H and 2S, and her long-reaching j.H, which can create safe pressure and even works for Cross-upAttacking your opponent after changing which horizontal side you are on, usually by jumping over them.. While certainly useful moves, Jack-O' cannot rely on only herself, as she is very weak without her servants.

She can summon up to three Servants at once, but just one Servant is enough to change her from a risky, dysfunctional character to an infectiously happy party-starter with a vast array of options. Jack-O' can use Servant Shoot or her Normals to launch the Servants like projectiles with a multitude of angles. Issuing Attack Command will make all servants attack, empowering blockstrings and combos. Issuing Defend Command will make all servants raise shields to deflect oncoming attacks. She can also pick up servants to carry them while fighting. She can even hit servants to enhance her own attacks, though manipulation of game mechanics. Once set up with servants, Jack-O' is very dangerous.

Jack-O's biggest flaw is her reliance on Servants to get going, which is made worse by Servants disappearing if Jack-O' so much as blocks a hit. Combined with Jack-O's generally weaker attacks, she can struggle under pressure, as she must work back her momentum, and a single mistake can be very punishing. However, these weaknesses can be overcome by making use of Jack-O's myriad of options and ensure she maintains her momentum, which requires creativity, plenty of lab time, and quick adaptation.

Whether you're a thrill-seeking daredevil with a bag of tricks, or a calculating tactician with a sure route to victory in mind, Jack-O' and her Servants have your back.
Lore:Jack-O is one of many "Valentine" clones of Aria, one which actually had her soul in particular. Initially incomplete, Sol takes her under his wing any way and she works alongside him as a bounty hunter.
Playstyle
Jack-O is a Technical type who dominates the battle with an assembly of Servants.
Pros Cons
  • Versatile: Jack-O' has a kit that can function for both zoning and close-range pressure thanks to long pokes, an advancing sweep, servants that can extend normals with projectile attacks, fantastic servant specials, and her many servant setups. Once Jack-O' has servants in position, she gains an immense amount of freedom to choose how she wishes to fight an opponent.
  • Strong Pressure: Jack-O' can lock opponents into brutally long and safe pressure strings, both midscreen and in the corner. These create incredibly good strike-throw mixes, chip damage blockstrings, and punishing frametraps. Knockdowns lead into powerful safejumps and mix-ups that lead into favorable pressure positions even when blocked thanks to the substantial plus frames of Attack Command, further enhanced by both versions of Cheer Servant On.
  • Tension Dynamo: Jack-O's long pressure strings and excessive number of special inputs in neutral make her one the highest Tension generating in the game without the need to harm opponents to get it.
  • Servant Gauge Dependant: Running low on her resources is extremely detrimental, as without access to Summon Servant or Servant Commads she is frequently punishable on block with her basic attacks and gains pitiful reward on any hit. Often making her heavily restricted by the slow recharge of her resources.
  • Problematic Neutral: With poor movement speed, bad recovery on her Normals, while being poor on block, and with many low-profilable attacks, Jack-O's is forced to get servants involved to establish threats, even at risk to herself.
  • Fickle Servants: Servants are easily destroyed, and their defensive abilities cost resources. They disappear when Jack-O' blocks, and cannot be protected from Overdrives or Burst. Even as projectiles, they can be taken out by simple jabs.
  • Self-Harming Mechanics: Jack-O' is good at disrupting her own setups unintentionally. An incorrectly positioned servant can turn her own okizeme unsafe, the servants can extend opponent's active frames making it easy to run into an assumed whiff, and even the act of hitting her own servants can reduce the cancel window of moves, causing strings to fail.

Servants

Jack-O' can summon Servants to fight alongside her. Jack-O' can both use servants directly, or issue them commands for them to perform.

Jack-O's Servant Command Specials issue instructions for servant, including attacking with a powerful strike, raising a large shield to parry incoming attacks, recalling servants to restore Servant Gauge, and setting them to explode after 3 seconds. These allow servants to support Jack-O' in all areas of the game, from pressure to defense.

Hitting servants with any attack except from Servant Commands, even other servants, will launch them towards the opponent as a projectile. The angle and speed of their trajectory depends on what attack was used, providing Jack-O' numerous ways to zone and attack from afar.

Unfortunately servants will eventually leave after 8 seconds. Servants also disappear when Jack-O' is hit, blocks an attack, or the servant is attacked by opponents, and if Jack-O' hits a servant they lose 3 seconds of their duration. If a servant is hit, Jack-O' and opponents follows the rules for on-hit cancels, meaning you can jump, dash, gatling, special, and even Overdrive cancel out of interacting with servants. This allows them to be used for many complex and intricate options unique to Jack-O'.

  • Servants do not leave until allowed to idle. Therefore they can be launched again while at 0 duration, or issued 1 final command.
  • Servants cannot fall off-screen. If the edges of the screen moves, servants will follow.
  • Opponents still receive full hitstop when hitting a servant, similar to hitting Jack-O'.
  • Jack-O' has a fixed 5F hitstop when hitting servants, even if she also hits an opponent at the same time.

Servant Gauge

GGST Jack-O ServantGauge.png

Jack-O' summoning and Servant Commands use her unique resourse, the Servant Gauge. The gauge refills passively, but Jack-O' can recall servants or spend Tension to restore it faster. Each portion of the gauge represents one servant that she can summon or one command she can issue. The gauge, in reality, is actually two seperate resources:

  • Summon gauge indicated by a glowing green bar. It is representative of the number of servants Jack-O' can currently summon.
  • Command gauge indicated by a servant's face, with a grey bar seperating it from the Summon Gauge. It is representative of the number of servant commands Jack-O' can currently issue. Additionally, the Summon Guage is restricted to the Command Gauge, reducing her potential summons.

The two gauges recharge passively and independently of each-other. The rate at which each gauge recharges is slowed down by the number of bars that gauge has filled, and if Jack-O's has any servants on the field (See Strategy for more information). The passive recharge may also be temporarily paused during some commands.

Jack-O' starts each round with a full Servant Gauge. Servant Gauge does not carry over between rounds.

Held Servant

Jack-O' can lift and hold her servants, either by summoning them into her arms with Summon Servant (Hold) or using Pick Up Servant.

During this, Jack-O' cannot block or backdash, but she gains a backwards run instead. She also cannot peform any Normal attack or Throw, but retains access to every Special moves and Overdrive, while gaining access to Throw Servant and Release Servant. These Servant Commands and Release Servant also replace her normal inputs, no longer requiring any motion inputs except for Servant Shoot.

Servants held by Jack-O' do not require any Command Servant Gauge to perform any of the commands, but it will still expend any remaining gauge that is available. Other non-held servants will not perform any action if there is not sufficient servant gauge.

  • The held servant's timer is paused while held.
  • Servant Gauge pause duration from Servant Commands is halved if only the held servant performs the command.
  • It is still possible to tech throw in this stance.

Jack-O's standing jab, and the fastest attack to launch a held servant.

Functions as a fast anti-air, but low reward and weak to air-to-ground attacks. Generally outclassed as an abare by her 2P, unless the opponent is airborne.

Its 1F faster recovery than 2P makes it slightly better for launching servants. The faster startup, recovery, and smaller hurtbox than 5K, but lack of jump and dash cancels, makes it better when using servants defensively from the ground.

A versatile kick for use in neutral, pressure, and as an abare.

With fast speed, great range, good reward, and difficult to challenge cancel options, this can be used in a variety of situations. It can also be useful as a fast, long-range anti-air with high reward, but weak to air-to-ground attacks. While among the slowest recovering K normals, it makes up for it with its considerably large range. Unfortunately it is easily low-profiled, as it attacks extremely high up.

If used to launch servants, it can allow quickly following up the servant with an instant Airdash jump-in or with a dash cancel, frametrapping on block and comboing on hit. However like 5P it launches a short range, while also extending her leg out, making it vulnerable to counterpokes.

  • Launches Servants in a short arc.
  • Jump and dash cancelable.
  • Range slightly increases on Frame 9. Additional range whiffs against crouching opponents, except Nagoriyuki, Potemkin and Goldlewis.

Fast, safe, and high reward, like most c.S, but needs servants to reach its full potential.

Unlike most c.S, on its own this move has fairly minimal pressure, as all follow-ups are unable to practically perform Tick Throws and eventually leave Jack-O' unsafe, giving her almost exclusively frametraps and basic corner carry. Therefore, it is more important to focus on getting servants set up, than landing c.S pressure on its own.

Instead, c.S excels when used in tandem with servants, becoming the foundation of her best pressure routes. Using this move while hitting a servant is barely behind the oppoent allows incredibly powerful cancels and links, creating her sandwich pressure. In the corner with a servant, c.S can easily lead into Jack-O's powerful corner pressure, particularly with Attack CommandGGST Jack-O 214K.pngGuard:

32 All 11 6 17 -9 none

Jack-O's long-range poke, as the largest attack that is not extremely unsafe to whiff.

Unfortunately, a very weak f.S, for its low reward, bad pressure, lacks any disjoint, is comparably easy to low-profile, and has functionally bad range/speed due to only reaching a standard range at Frame 15. As a result, Jack-O' is much more comfortable playing away from a spacing where she needs to rely on it.

Unlike most of Jack-O's normals there's not much other utility to the move, making it primarily just a neutral poke and a common blockstring extension off c.S.

Aggressively fast and powerful attack, but catastrophic on whiff.

With fast movement, fast startup, and some of Jack-O's best combos on Counter Hit, this is one of Jack-O's most powerful mid-range options. Better still, this is one of Jack-O's safest moves on block, due to the large pushback, frame advantage when cancelling into Summon Servant (Hold)GGST Jack-O Summon Servant.pngGuard:

. Opponents should naturally respect this move. Where it falters is its long recovery, where on whiff she naturally drifts into the opponent's best punish range, making it extremely risky if opponents can backdash out of range. Additionally it easily loses to low-profiles and 6P, making it easy to be defensive against.

When paired with servants in neutral, 5H is the fastest and longest-range method to get long-range servant bounces, especially as you can cancel off the servant to instantly cut Jack-O's movement, avoiding any of the recovery and movement risks. It can even hit servants behind Jack-O'.

Can work as an unusual anti-air against low airdashes, due to its long reach quickly overcoming the gap before the opponent's attack, but is generally risky compared to her other anti-airs.

  • Bounces Servants in a long arc.
  • Hits twice, launching on the 2nd hit.

Universal overhead attack. Tapping D gives a fast but weak overhead, while holding down D with give a much slower but much more powerful strike.


Uncharged Dust Attack

While a usually very weak overhead, Jack-O' can easily jail into it, and has many practical uses for it.

By cancelling from 5K or c.S while hitting the opponent and a servant at the same time, Jack-O' is able to completely jail into the overhead. When backed up by 50% Tension for RRC, this becomes a practical mixup as it can't be defeated by backdashes, jabs, or invincible reversals.

In addition, Jack-O' can combo off it without further meter, such as during during pressure from Cheer Servant On HGGST JackO Cheer Servant On H.pngGuard:

when the opponent hits 100% R.I.S.C., in the corner when hitting a servant with a damaged wall (for a 2-hit Wall Stick), or with good spacing of Jack-O' and a servant in the corner to set up a full meterless combo. Used correctly, these give Jack-O' access to a fast mixup for ending rounds when it would be otherwise impossible.


Charged Dust Attack

On-hit, holding 8 will activate Homing Jump for a large combo opportunity.

Slow, unsafe, but rewarding overhead. Jack-O' can frametrap into it, but once opponents can react and punish this, it stops being practical.

By cancelling from c.S within sandwich pressure, the Charged Dust becomes a tight frametrap, making it much harder to respond without properly reacting. Unfortunately it is still entirely unsafe on block and easily reacted to, making it impractical for her to use unless the opponent is unprepared. This is made worse as her Homing Jump combos are very poor, with some of the lowest damage in the game. Once opponents can react and punish this, it stops being useful. Though there are technically ways to make it advantageous on block in the corner, the spacings and setups are so precise that an equally skilled opponent is probably prepared enough to simply react to it any time it happens.

Jack-O's crouching jab, and her safest abare. Fairly standard jab.

Hits crouchers and is tied for her fastest attack, but very low reward on hit. Like most 5F jabs, it can be used to challenge Throws and delayed cancels, while hitting low enough to challenge crouching attacks. It can still be low-profiled by some attacks, but generally offers very strong coverage.

24 Low 6 3 12 -3 F6~20 Low-profile

A very fast poke, that doubles as an abare and pressure tool.

Hitting Low, with impressive range for its speed, while also low-profile, and setting up for okizeme on any hit makes this a powerful poke to contend with in close-quarters and for neutral advances. Its low-profile and speed offers great coverage, as most characters lack faster moves that can hit so low or from so far. The biggest drawback is the problematic on-block, as going into 2D leaves her at a disadvantage.

While 1 frame slower than her 2P, this covers considerably more range and cannot be low-profiled, making it very strong against gaps in pressure, especially those made by Faultless Defense where Jack-O' can still reach but the opponent may lack strong threats that cover the distance fast enough or risk whiffing if you simply don't act. Even if it whiffs, such as to airborne attacks, its short recovery can make it comparatively safe and difficult to punish.

2K also plays a critical role in Jack-O's pressure. With its cancel into 2D > 214K, it is one of her strongest optons to get her into range to begin stronger pressure, but also avoids hitting servants, maintaining their duration.

  • Launches Servants in a short arc.
    • Whiffs on servants at their default height.

A highly-specialist anti-air for covering attacks where 6P will miss.

Specialist role to a fault, this anti-airs specifically attacks that move in such a way her 6P can't challenge properly. This move is either very potent for challenging highly specific options the opponent has, or the opponent doesn't have those options, rendering it mostly useless. Do not underestimate its value when it can be useful, however, as its coverage is quite unique and difficult to match.

This move serves zero purpose on the ground and should never be used as such, with less range than her Throw, is extremely unsafe on block, and sets up for barely any threat besides a 5H gatling. While it launches servants similar to 6H(1), it is slightly slower and shorter range, making it outclassed if you can correctly cancel off the servant. This is strictly an anti-air move.

Used in some pressure setups but otherwise unremarkable. Her most rewarding punish.

Due to its advancing movement, slower startup, shorter hitbox, and bad recovery, this move is not very good for blockstrings or in neutral, and is generally outclassed by her 5H or 2D. It's real value lies in its uniquely lower pushback on block, usefully setting up for some of Jack-O's corner pressure and for advanced use is a strong opening to Cheer Servant On HGGST JackO Cheer Servant On H.pngGuard:

The low-profile and slightly more rewarding sister to 5H, but much worse on block and even worse on whiff.

With all of the same offensive benefits as 5H, Jack-O's sweep is fast-moving (though a little slower than 5H), a hard knockdown on hit, and some of her best combos on Counter Hit, with the unique perk of being low-profile, this is similarly one of Jack-O's strongest aggressive mid-range options.

. However, this is also riskier on block. Conversely, while Servant Shoot can make the RPS safer, it destroys any reward she had on hit. This makes hitconfirming with 5K and 2K very important, and using it raw is particularly risky as you must anticipate if it will hit or not. Though, if you are using this raw, you probably are assuming it will.

Though this move is notably low-profile, do not mistake it for other ultra-low-profile attacks: it isn't low-profile until later into the animation, and most f.S and 5H attacks will still hit the taller back-half even then. This is best at getting under attacks that naturally hit high, or hit the mid-height with only a short range.

2~12 Above Knees

The anti-air attack. Also a counter to pokes in neutral.

Like most 6P, this has upper-body invulnerability, making it objectively the best anti-air to easily defeat airborne attacks (unless they hit especially far down), but, it offers less reward than her other anti-airs. Its upper-body invulnerability can also blast through long-range pokes such as f.S attacks. This is also one of the better 6P attacks, as its invulnerability lowers extremely quickly, giving her slightly more time to react.

6P is also the fastest way to bounce a held servant with a long-range arc due to hitting higher than 5H, which also sends them further due to the added height, making it good for poking at long-range.

For poking jumps from long-range. Not particularly safe or rewarding.

It has incredible anti-air range, and is especially good for catching far air dashes. Unfortunately, up close, it can whiff underneath advancing jumps, and is very slow for challenging airdashes. Furthermore, it is actually very low reward, even on Counter Hits. It doesn't set up for any major okizeme or combos without the corner, at which point it's at a spacing where it is more risky. While it is a 2-hit move, the first hit is rarely important, as it isn't very large, disjointed, or rewarding, and the extremely long second hit will leave Jack-O' wide open. In some positions this can be used to check against 2 approaches, with the first hit covering fast dash-ins, and the second hit covering a slower airdash, but this is not commonly the safest or more rewarding option.

Its more valuable role is for launching servants. Hitting a servant with 6H(1), then immediately cancelling into Summon Servant (Hold)GGST Jack-O Summon Servant.pngGuard:

(and have it whiff) allows it to be used as a pre-emptive anti-air while allowing Jack-O' to run underneath, before coming back down to hit some distance away on the ground, giving it strong coverage for approaches in neutral.

The effective range of the second hit on grounded opponents depends on their height. For most characters this is rarely a threat, but specifically Faust and Goldlewis find this particularly annoying for its enormous range against them standing and easily catching their common air options, while challenging much of their moveset.

  • First hit launches Servants up in a high arc, while second hit launches in a long arc.
  • 6H(2) reaches maximum range and height on frame 27.
  • 6H(1) causes floating crumple on hit, 6H(2) does not.

Fast air jab, and a mixup tool.

Standard air jab, it's her fastest air attack, and good for challenging Air Throws. Also a faster jump-in after an instant Air Dash, but is very short range. As it can self-gatling, it can be used repeatedly to make itself advantaged on block and combo on hit, but this will do very little damage.

Also used in mixups with an F-ShikiSometimes known as "Fuzzy Overhead". When you are in blockstun, you can switch high/low blocking, but your blocking animation and hurtbox does not change until you leave blockstun or block another attack. F-Shikis take advantage of this and use overheads that would miss on crouching characters, but not on standing characters. set up by j.S or j.H, by hitting immediately after a low Jump Cancel and comboing into Attack CommandGGST Jack-O 214K.pngGuard:

Fast but short air-to-air attack.

Mainly designed for fast and reactive jumping air-to-airs thanks to hitting above Jack-O' quickly, and leading into a combo, with more reward if airdash cancelled. On block, airdashing can easily result in a crossup, while not airdashing remains sameside, presenting a light mixup even if you do not deal damage.

From the air with a Held Servant, j.K is good for launching a servant a short distance in front of Jack-O', especially for its air dash and jump cancels, but lacks the safer landing opportunities of j.P.

The deeper-hitting sister to j.H. Strong jump-in for fast offense.

This is the primary option for instant airdash offense as it can hit crouching opponents immediately, while still having some cross-up attack to make it still very reliable to hit from any spacing. However, it lacks the same on-block threat j.H has due to only hitting once, and will hit much later if it does crossup. In some okizeme, even on cross-up, j.S is generally preferred for hitting deep and doing the most damage of Jack-O's air attacks in the single hit it will have before landing.

From the air with a Held Servant, j.S ground bounces the servant, making it hit at an extremely short range, but the lingering hitbox of the servant makes it very hard to challenge with a run-under unless done pre-emptively. This is most commonly paired with a backward jump for an extremely defensive maneuver; however it maintains the Air Dash Cancel to suddenly mount offense on unsuspecting opponents.

  • Launches Servants into a ground bounce.

While it does maintain Air Dash Cancels, the use of a 6P will anti-air both the servant and Jack-O'. However, by hitting at such a high angle, opponents may struggle to 5P the servants, effectively stalling them longer than otherwise.

Stall for servant gauge. A cheeky way to end rounds.

As one of Jack-O's only ways to zone without expending any Servant Gauge, the role of this projectile is simply to stall for Servant Gauge, as it can disrupt the opponent's movement while building space to allow summoning. Unfortunately, extremely weak outside of this role, as not only is it slow, but it is extremely dangerous when called out for its huge Counter Hit recovery, and has absolutely zero reward on hit. Until, that is, the opponent is so low health it becomes a oneshot, where this becomes surprisingly annoying as it covers a large amount of space while being hard to punish without calling it out.

While it is Air Dash cancellable, it can neither combo nor enforce a blockstring, the opponent can always 6P the approach. However, the airdash can result in a cross-up, and the threat of an Air Dash can potentially stall their approach. You can also instantly jump cancel into another j.D to prolong the stalling.

From the air with a Held Servant, j.D shares its angle with j.K, but will keep Jack-O' above the servant, potentially crossing over 6Ps, but is much more telegraphed. This can also be used after bouncing a servant with j.K or j.S to create a defensive wall of projectiles while creating more distance.

  • Launches Servants in a short arc.
  • Slows down Jack-O's momentum, then pushes her slightly backwards.
  • Jump, Dash, and Special cancelable after the projectle connects.
  • Full Counter Hit recovery.

Servant Shoot

Anti-zoning projectiles and the final move of any blockstring.

As Jack-O's only non-servant special, every blockstring is able to cancel into this as a final frametrap. Unfortunately, for lack of any cancels without servants, it locks Jack-O' into an unfavourable defensive RPS where Jack-O' cancels into Summon Servant (Hold)GGST Jack-O Summon Servant.pngGuard:

to be safer. However, since this can be done before Servant Shoot, the threat of the frametrap can cause opponents hesitation, and thus give her safety in ending early. Unfortunately, even on Counter Hit, this move has almost no reward besides corner carry, unless in the corner.

With a servant nearby, these weaknesses disappear, and it can instead be used as part of many pressure loops and setplay for extending blockstrings before needing to use Attack Command.

When used for launching servants, it is rather slow and can be easily stopped by any 5P, however it crushes most projectiles, making it extremely good for combatting opponents attempting to zone Jack-O', assuming their projectile has a lower Clash Level. The launched servant also hits barely high enough to catch instant Air Dashes from some distance away, but this is avoided by simply doing a slightly higher airdash.


Air Servant Shoot

A bizarre way to enhance j.H through a whiffed cancel.

By cancelling the first hit of j.H into Air Servant Shoot, Jack-O' will land early. Not only does this enable a faster 2K or Throw for a small (fuzziable) mixup, but by disrupting horizontal momentum you will land further away, allowing you to land further out, potentially in range of Jack-O's c.S while safe from the opponent's Throw, improving her pressure options on block and combos on hit

From the air with a Held Servant, Air Servant Shoot launches at a straight trajectory above the opponent, going slightly further than Air Throw Servant for easier crossup servants but slower and with a shallower arc. If she delays the Air Servant Shoot, this can also make the released servant hit along the ground, being a faster substitute for landing into a grounded Servant Shoot. She can also cancel into it after bouncing a servant with any air attack except j.D, to launch an idle servant below, covering multiple angles at once.

This move is used in virtually every input string Jack-O' has. Get used to inputting this a lot.

. Servants are so critical that summoning can act as a reward for good interactions, as despite its short animation it is somewhat risky, placing her into Held Servant stance where she cannot block or use normal attacks until she releases or throws the servant. This lends itself to needing space, a knockdown, or some kind of pressure to allow her the opportunity to do so.

Thanks to utilising only the Summon part of the Servant Gauge (of which nothing else uses), this is generally cheap and can be used frequently. However, there is still a limit, and ironically more servants does not nessecarily mean more threat to the opponent, while the act of summoning always opens some margin of risk. It is worth identifying why you need to summon and pace the summoning around what her gauge allows.


Summon Servant (Place)

Tap and release P to immediately place down the servant.

A convenient substitute for summoning and releasing quickly, that sometimes is needed for placing servants a little more to the side.

With exactly the same frame data as 236[P], hs.D, there's not many reasons to use this except for its easier input. However, some combos and okizeme find practical use for its different placement of the servant. Otherwise, most of the time it is better to hold the servant, as it allows more freedom to react mid-sequence, and there are advantages to having the servant fall from above Jack-O', such as for giving it more range when hit by a normal.

This move can also be used as an extremely slow and risky pressure reset. When used as 236P, 2P, it is a 30 Frame pressure reset that completely secures servant pressure. This is very aggressive and risky, but extremely rewarding for Jack-O's pressure, especially near the corner.

Where it is most powerful is actually when you fail to pick up a servant Jack-O' has just launched or bounced away from herself. This can give any move a 14 Frame fast cancel without locking her into Held Servant. This enhances her zoning, combos, and can even be applied in some unique pressure routes for frametraps and tick throws. However, this is very spacing sensitive, making its application sometimes quite complex.

, and the Attack Command will now push them towards Jack-O' for easy sandwich pressure. However, opponents can quickly approach without the servant being fast enough to follow behind, making it strong offensively but defensively weaker.

While a very easy method of zoning servants, it is very slow, making it very easy to 5P thrown servants. Instead it is more commonly used as part of okizeme, due to its high range and lower recovery. It can also work as a pressure extender in the corner. This can catch jumping opponents, jailing them into easy pressure, but also as a pressure reset, leaving Jack-O' so plus she can dash back in with c.S or 2D.

Releases the servant in front of Jack-O. This is used in many situations to position a servant favourably, such as to hit it with an attack as a zoning tool, or releasing a servant mid-air for okizeme. During Jack-O's defensive RPS situations she oftentimes jumps or runs away while holding a servant, so that she has time to release the servant and allow her to use attacks and block again. This can also often be used to simply change tactics when holding a servant, such as for punishing a whiffed attack.

A pressure reset for use when you don't have servants to work with.

Thanks to its extremely short duration, almost any blockstring can cancel into this as a pressure reset into 2K (25F) or c.S (26F). It is fast for a reset, but is extremely telegraphed. And, unfortunately, Jack-O' has less pressure worth resetting for without a servant to continue the pressure

Thankfully, if you have spare servants not helping, this at least compensates Servant Gauge while removing servants that would slow down the recharge, making it very cheap. It can also just be used to simply make Jack-O' safe, even her risky 2D becomes safe on block, but this freely allows the opponent to pressure rather than return to neutral.

Despite its name, this move is borderline useless when you have servants active on the opponent (outside of combo routes), as it is almost impossible to not end up on a net negative with Servant Gauge, while also sacrificing pressure, and loudly telegraphing this fact. Even during the extremely niche Countdown, there's not any particular reason to do this.

Setplay, zoning, poking, the sky is the limit.

Causes all servants on screen to attack, moving forward in the process. This is one of the most powerful abilities in the game, but it is tied to both Servant Gauge and servants. Not only does this allow Jack-O' to easily reset any blockstring with a frametrap, by giving time to dash back for a c.S, it also allows virtually any hit to combo, move the opponent in blockstrings (especially back towards Jack-O'), and lock down opponents when a servant is nearby for fear of being hit at any moment. This is primarily why Jack-O' wants servants on the opponent.

Even if Jack-O' is not nearby, Attack Command can loop into itself, playing a major role in zoning. The only real downside to this move is the Servant Gauge cost, costing 1 bar of Servant Gauge and pausing its recharge for 1 second. If she ever runs out of Servant Gauge, her presure fundamentally breaks down for lack of Attack Command, and Servants become completely trivial as threats.

Protective shield, good for safely checking attacks in neutral.

All servants put up a large shield, making them impervious to most attacks. If the shield is attacked, the servant will parry and place the opponent into Guard Crush. With the lingering active time and large shields, this is very low-risk as one of the only counterplays is to run past the servant to attack Jack-O' at point-blank range, making it extremely good for disrupting pokes in neutral.

Defend Command is also a potent anti-air. Not only does it defeat disjoints, but it's impossible to bait out the timing when it can cover Jack-O' permanently. Furthermore, on anti-air the Guard Crush launches the opponent, usually giving Jack-O' the opporunity to run underneath for a truly ambiguous left-right mixup using her c.S, giving her significantly higher reward.

For flashy, expensive, round-ending combo optimisations. Practically useless anywhere else.

All active servants begin a Countdown, at the end they will detonate into a large explosion, destroying the servant in the process. Jack-O' has some unique combo routes utilising Countdown, scoring significantly more damage. However this costs all of her Servant Gauge, and sometimes even harming herself. The role of these combos is to end the round, as these costs become irrelevant if it immediately wins. These combos are not vital, however, and are more advanced optimisations of her damage potential.

Despite appearing to be useful for pressure and setplay, the move is almost universally bad for Jack-O'. Not only does activation always leave her minus while loudly telegraphing this fact, but the explosion sets up for less result than Attack Command can usually offer, and the loss of Servant Gauge means inevitably any result is likely to have horrible okizeme that disadvantages Jack-O'. While it has some unique setplay and interactions, these are generally completely outclassed, and consequently, never used. While a few practical uses do exist, they are highly specific and not situations that can be commonly set up.

  • If a servant is held when the explosion begins, Jack-O' immediately exits her Held Servant stance.
  • Servant gauge will not regenerate for the full duration of the countdown.
  • When the explosion begins, the servant gauge will drop to 0, and begin refilling immediately.
  • The explosion can hit Jack-O, Jack-O's servants, and the opponent.
    • Opponents stuck to the wall will not break through if hit by the explosion, instead falling back down to the floor, allowing for combo extensions and corner okizeme.
  • The servant's duration timer is ignored when counting down.

A powerful but flawed invincible Command Grab with some unique perks, but is the least reliable invincible reversal in the game.

As a reversal, it is very poor. It will fail against any airborne attacks and delayed (throw immune) command grabs, while also being slower than most invincible Overdrives, with excruciatingly long recovery. Furthermore, while it has substantial range, it does not hit extended hurtboxes, allowing opponents to simply outspace it entirely. These limitations combine to make it very easy to pressure Jack-O' regardless of if she has Tension or not. To compensate, it deals extremely high single-hit damage, blasting through the effect of Guts, and taking any character from at least 26% health. Among its few upsides, FED cannot fail to crossups, and will simply hit behind her to any range. Additionally, opponents cannot kara into Faultless Defense, making it easier to catch people early into an attack. However, these are minor compared to its glaring flaws.

In addition it is a notable combo ender for okizeme, which can maintain her offensive momentum. However, unless used extremely early, expect it to deal minimal damage. Breaking the wall with Forever Elysion Driver can also help secure an offense where Wallbreak is often a major problem for Jack-O'. Despite this, it can still be advantageous to not break the wall. In which case, with good spacing Forever Elysion Driver can hit opponents on the wall without breaking it, leading directly into corner pressure. Even in the event of a Wall Stick with a servant imminently breaking the wall, Forever Elysion Driver can be used immediately during the pause to secure a better Wallbreak.

Lastly, Forever Elysion Driver can be used during a Guard Crush from Defend Command as an automatic punish for a total of 158 damage (193 on Wallbreak). This is usually inefficient use of meter for damage, given the advantages of Defend Command, but is your only guaranteed damage if nessecary.

  • Immediately recalls all servants on Frame 1, refilling Servant Gauge for +0.5 bars of Command Gauge and +1.0 bar of Summon Gauge per servant.
  • Command Grab, cannot be blocked but cannot hit an opponent if they jump or are airborne.
    • Opponents in Faultless Defense cannot jump for 1 frame and therefore cannot jump out in time (but may still use Psyche Burst to escape if available).
    • Unlike other command grabs, it can hit during Guard Crush, Wall Stick, and in Combos, even if they are airborne.
  • Hitting an opponent in the corner causes a Wall Break and leaves Jack-O' at +36 frame advantage afterwards.
  • For 10 frames during the cinematic freeze, all projectiles and the opponent will be completely frozen, however Jack-O' will continue to move forward and her servants will continue to move and act during this time.

Strengthen servants and push opponents back extremely safely, but needs space to set up.

Servants become almost invincible for 5 seconds, making Jack-O's zoning win immediately. Once established, Jack-O' is able to approach safely, as it becomes very dangerous for them to do anything, and even Burst becomes weakened. Unfortunately this does very little in establishing any new pressure, as Jack-O' can still be harmed and her Servant Gauge remains limited, making its utility more for covering ground than forcing a powerful offense. This is best set up from as far away as possible, where Jack-O' cannot be punished but also allow her to approach as much as possible. This can even be quickly set up after a Burst to entirely reverse pressure at almost any time.

Unfortunately this is problematic in practise as many characters are equipped with powerful counterplay. Projectile Overdrives will often entirely invalidate this super, some have powerful full-screen offense to threaten even its short recovery, and some can even stall out the entire buff by jumping into the air. This makes it heavily situational to the matchup and circumstances, where you may need to find a gap where the opponent cannot act immediately (e.g. during a jump) to set up.

  • Prevents Servents disappearing after Jack-O' blocks or is hit by an attack.
  • Gives Servants infinite Guard Point, preventing them from disappearing when attacked.
    • Servants will still disappear when hit by an Overdrive or Psyche Burst (Unless Jack-O' is hit by the Psyche Burst first).
    • Opponents receive less hitstop when hitting servants, reducing it down to instead 4 frames, similar to Jack-O' hitting her own servants.
  • Temporarily pauses Servants' duration, including allowing Jack-O' to hit them any number of times without disappearing or losing duration.
  • Both versions can be active at the same time, providing the benefits of both simultaneously. Their durations will wear-off independently of each-other.

Servants: 4~14F Full

Specialist corner pressure tool, for cranking R.I.S.C. and chipping down opponents.

Providing continuous Servant Gauge and halting Servants' duration for 5 seconds, this tool enables Jack-O' to loop pressure continuously. In particular looping 5K > 2D > 214K will not be pushed out by Faultless Defense while still building considerable R.I.S.C. Once R.I.S.C. hits 100%, Jack-O' is free to use an Uncharged Dust Attack at any time, as it will launch into a full combo due to the R.I.S.C. Counter Hit effect. If the opponent doesn't use Faultless Defense, the much stronger c.S > 236K > 214K loop can be used instead for even more chip damage and R.I.S.C. gain.

To set up, Jack-O' must usually perform a fast cancel from hitting a servant (especially 236K for its easy buffering). Done correctly this jails into 2K, and beginning the pressure in full. This can also be set up from some sandwich pressure with more technical setups, allowing carrying into the corner before beginning the pressure.

As an unconventional offense, it suffers unconventional counterplay. Looping attacks this way makes baiting a YRC nearly impossible. Additionally, using Faultless Defenses forces her to use the weaker blockstring, while stopping R.I.S.C. gain entirely and preventing the mixup. Therefore the strength of this move entirely hinges on how much Tension and R.I.S.C. the opponent starts with.

  • Overrides Servant Gauge recharge rate to a continuous 1.2 bars per seconds, regardless of current charge or active servants.
  • Prevents Servant Gauge recharge being paused when using a servant command (but will not remove any current Servant Gauge pause).
  • Temporarily pauses Servants' duration, including allowing Jack-O' to hit them any number of times without disappearing or losing duration.
  • Both versions of Cheer Servant On can be active at the same time, providing the benefits of both simultaneously. Their durations will wear-off independently of each-other.
