Command-input move

Terry's Buster Wolf, which can only be executed via a command input.

Command-input moves, also known as Command Attacks, are upgraded versions of the special moves of Ryu, Ken, Terry, and Kazuya that requires a specific motion on the control stick and a button press in a specific window of time.

Overview

Terry's Burning Knuckle. Standard input (top), command input (bottom).

In traditional fighting games, a "command input" is typically defined as any combination of a direction and/or button press that causes a move to be executed. In the Super Smash Bros. series, it is used for attacks that require more input than a simple direction + button press, typically those that require a series of directional inputs on the control stick prior to executing the attack. In Ultimate, taunt inputs can be used instead of the control stick.

While most command input special moves can be activated by simply pressing the A or B buttons and holding a direction, they are intentionally made slower and weaker to reward players for using the inputs instead. Command versions of these moves are more complicated to activate, but have the benefit of being faster, more powerful, and sometimes have added effects.

There are also some moves that can only be activated via command input, such as Shakunetsu Hadoken, which are often integral to their respective character's gameplay. These moves are often at their most useful during combos, with Ken using his for combo purposes, enabling numerous kill confirms. With the addition of Terry and Kazuya in Ultimate, some command input special moves can also be "unlocked" when reaching a certain damage threshold, known as Super Special Moves and Rage Drives respectively. These moves often have far more complex inputs, but deal extremely high damage and knockback, making usage extremely rewarding.

There are also some advanced techniques that can be utilized with command inputs, such as charge partitioning, and Kara Canceling. All command input-related moves — except those that are related to Kazuya's Crouch Dash — can be drop cancelled, making them easier to use on platforms.

Moves with Command Inputs

Move	User(s)	Standard input / Requirement	Command input	Command input description
Hadoken	Ryu Ken	Neutral special	↓ ↘ → + attack/special OR ↓ → + attack/special	The Hadoken deals more damage and the user will announce the move's name in a fiercer tone. If Kirby copies Ryu or Ken's neutral special, he can perform the command input version of the move.
Tatsumaki Senpukyaku		Side special	↓ ↙ ← + attack/special OR ↓ ← + attack/special	Tatsumaki Senpukyaku will be more powerful. Ryu will announce the move's name ("Tatsumaki Senpukyaku!" while grounded, "Tatsumaki!" while airborne) instead of grunting, whereas Ken will merely announce the move's name in a fiercer tone.
Shoryuken		Up special	→ ↓ ↘ + attack/special	Shoryuken will be more powerful while having more intangibility (frames 1-14 versus frame 5) and lower landing lag (16 frames versus 23 frames) and the user will announce the move's name in a fiercer tone.
Shakunetsu Hadoken	Ryu		← ↙ ↓ ↘ → + attack/special OR ← ↓ → + attack/special	A "Yoga Flame" input. A red, multi-hit Hadoken which uses the flame effect. It has more combo utility and hitstun than the average Hadoken. If Kirby copies Ryu's neutral special, he can perform this move using the command input.
Oosoto Mawashi Geri	Ken		← ↙ ↓ ↘ → + attack OR ← ↓ → + attack	An outward roundhouse kick. If the button is held, Ken will perform an Inazuma Kick, which is similar to his far-range held neutral attack and deals an impressive amount of shield damage.
Nata Otoshi Geri			→ ↘ ↓ + attack	A swiping crescent kick. If the button is held, Ken will perform an Inazuma Kick, which is similar to his far-range held neutral attack and deals an impressive amount of shield damage.
Burning Knuckle	Terry	Forward special	↓ ↘ → + attack/special OR ↓ → + attack/special	Burning Knuckle will be more powerful and will grant intangibility to Terry's attacking arm, with a green-yellow trail behind him. It should be noted that the input is reversed from his home series, as it is normally a quarter-circle away from the opponent.
Crack Shoot		Backward special	↓ ↙ ← + attack/special OR ↓ ← + attack/special	Crack Shoot will deal more damage in general and the second hit will deal drastically increased shield damage, with the tipper hitbox dealing an additional 20 HP of damage. This makes it excellent at breaking shields.
Power Dunk		Down special	→ ↓ ↘ + attack/special	Power Dunk will be more powerful, grant intangibility during its ascent, and enable the last hit to meteor smash during its later frames.
Rising Tackle		Up special	Hold ↓ for 24 frames, then ↑ + attack/special within 10 frames	This type of input is know colloquially as a "charge motion". Rising Tackle will be more powerful, hit more times, and grants full body intangibility from frame 5. There is an 11 frame leeway to continue charging Rising Tackle if ↓ is released; this is known as charge partitioning.
Power Geyser		Super Special Move	↓ ↙ ← ↙ → + attack/special OR ↓ ← ↓ → + attack/special	Terry will punch the ground and a massive geyser of energy will explode in front of him, dealing incredibly high damage at the cost of slow startup and high ending lag. Has 5% damage-based armor on frames 1-14.
Buster Wolf			↓ ↘ → ↓ ↘ → + attack/special OR ↓ → ↓ → + attack/special	Terry will launch forward and if he connects with the opponent, they will be grabbed and thrown for incredibly high damage, similarly to the close-range grab hitbox of Lucario's Force Palm. Unlike Force Palm, there is only a grab hitbox, meaning Buster Wolf is extremely punishable if it fails to connect. The move is also a hit grab, much like Isabelle's Fishing Rod, meaning that opponents can effortlessly shield the move and punish it out of shield. Has 8% damage-based armor on frames 1-15.
Crouch Dash	Kazuya		→ ↓ ↘	Causes Kazuya to dash towards the opponent while crouching. He is in a crouching state and his upper body is intangible for a brief period, making it useful for quickly closing gaps.
Wind God Fist			→ ↓ ↘ + tap attack	A powerful uppercut. If the button is pressed the frame before, on, or after the ↘ motion (↘ needs to be held for the last case), it will become Electric Wind God Fist, which paralyzes the opponent and will push back shielding opponents. This attack will become Dragon Uppercut if the attack button is held for more than 6 frames, regardless of if it would've been WGF or EWGF. In Tekken, it has only a one-frame window instead of three and is known colloquially as a "just frame" attack in traditional fighting games. This can also be performed with the grab button instead of the attack button, however the grab button must be pressed after the ↘ input and not on or before, otherwise Kazuya will do a normal grab. When performed this way, EWGF will have only a one-frame window (the frame just after ↘). Unlike the normal method, holding the grab button for any length of time will not transition into Dragon Uppercut.
Dragon Uppercut			→ ↓ ↘ + hold attack	An electrified jumping uppercut with his left hand with very high knockback. Replaced by Kazuya's Rage Drive during Rage.
Spinning Demon to Left Hook			→ ↓ ↘ + special	A low sweeping kick followed by a hook from his left hand. During this move, Kazuya has brief intangibility. Replaced by Kazuya's Rage Drive during Rage if special is held for more than 5 frames.
Left Splits Kick			→ → + attack	Kazuya stretches his left leg upwards and swings it downwards immediately after. Reflects projectiles from frame 7 onwards with a 2.4× damage multiplier.
Gates of Hell			↘ ↓ ↘ + grab	Kazuya bends the opponent back and kicks them away. His arms will glow red prior to the grab and a special camera angle activates in 1-on-1 battles.
Rage Drive		Rage	→ ↓ ↘ + hold attack	Replaces Dragon Uppercut. A stronger version of Heaven's Door which itself has weaker versions that can be performed with a grab or using Heaven's Door on the ground. Has super armor on frames 5-12.

Negative Edge

Negative edge is a mechanic involving any command input special move, which is present in traditional fighting games. To perform, hold the attack or special-move button during an attack, input the special move, and release said button shortly after the attack is over. Essentially, pressing and releasing an attack button can be treated as a half-A press in the context of a command special move. This will always be treated as a tap input, so only the weakest variations of the special moves will occur. This is not to be confused with buffering, which is where a player holds a button to perform an action on the first possible frame. Negative edge is present in SSB4 and Ultimate.

Negative edge primarily exists to make combos with special moves easier for players to perform, making it a good technique for new players to utilize when starting out. For example, with Ryu, it is possible to use negative edge to make canceling his close strong neutral attack into Shoryuken easier. However, as aforementioned, this can only result in a weak Shoryuken. As such, learning the inputs without negative edge is important in order to get full use out of the characters.

Due to negative edge only resulting in weak inputs, it tends to only be optimal in cases where the weak input is necessary. This best applies to situations such as Terry's neutral aerial into Burning Knuckle, which can otherwise be difficult to recover from using off-stage. Additionally, at higher percentages, the strong version can sometimes be too slow to connect reliably. For a more niche case, against characters like Mega Man, Robin, and Ken, there are situations where Terry's up tilt can be canceled into a weak Crack Shoot and result in a dragdown; normally at around 75%. Negative edge can be used to consistently get the weaker version, reducing the chance of human error.

Tiger Knee

Tiger Knee is an advanced technique exclusive to Ultimate that involves making use of a jump alongside command inputs. Because none of his command input special moves can be used off the ground Kazuya cannot make use of his technique. The name comes from similar motions in traditional fighting games. This can be applied to any command input special move that can be used in the air; ergo, Super Special Moves, Oosoto Mawashi Geri, and Nata Otoshi Geri cannot be utilized with this technique. It's mainly viable with Terry thanks to the sheer amount of aerial pressure he can exert using his special moves. However, there is niche utility with Ryu and Ken as well, albeit being extremely committal and not having much benefit over simply jumping and doing the input.

To perform the technique, input a jump alongside a singular A or B press prior to inputting a command special; for example, to do a Tiger Knee Burning Knuckle, one would do ↓ ↘ → + Jump + Attack / Special, in which the aerial version would be done, ignoring the ledge. Due to requiring a jump prior to the final input, it cannot be used alongside a special cancel, which puts a firm cap on its utility.

If performed correctly, a jump will occur at the same time as the special move. This has various applications for Terry, such as autocanceling Power Dunk, getting a higher arc with Crack Shoot, and using Burning Knuckle's aerial variation closer to the ground, allowing it to drift past the ledge. An autocanceled Power Dunk using this technique is even on shield, enabling Terry to mix up with moves like neutral attack. Additionally, it acts as a somewhat committal way to get past projectiles, which can also be applied to Tiger Knee Crack Shoot. Tiger Knee Burning Knuckle allows Terry to get around the grounded version locking him to the ledge, boosting its potential threat range on-stage and making Terry's edgeguarding much less committal. With respect to Ryu and Ken, using a Tiger Knee Tatsumaki Senpukyaku can force the move to do a rising version, acting as a committal anti-air option.

Renda Canceling

Renda canceling, is an advanced technique introduced in Ultimate which makes it easier to cancel normal attacks into super. It is a misnomer based on the Renda-Kara-Cancel used in Super Street Fighter II, which involved kara-canceling the startup of a self-chaining light attack into a super combo in order to ignore the restriction that chained light attacks cannot special or super cancel. This technique however does not involve self-chaining light attacks (the renda in renda cancel), nor kara-cancels, it is simply an execution trick that makes it easier to perform special cancels from tilts.

This technique consists of inputting part of a command special, attacking with the C-Stick, and subsequently finishing the input. It occurs because C-Stick macros cannot trigger special moves (so ↓ ↘ → + C-Stick won't be interpreted as a burn knuckle, just down tilt), while keeping the completed part of the special move motion in the command buffer. The purpose of this is making it easier to special or super cancel from tilt attacks, because you can do part of the motion before the tilt, and part of the motion as the tilt connects, instead of needing to do the whole motion during the tilt attack.

For example, with Terry, one can input ↓ ↘ →, down tilt using the C-Stick, and finally ↓ ↘ → + Attack / Special. If performed successfully instead of using Burning Knuckle, Terry will use Buster Wolf, reading the ↓ ↘ → prior to using down tilt, and the ↓ ↘ → during the down tilt. Because only tilt attacks cancel into specials, setting the C-Stick to tilt attacks is necessary.

This technique is essential for Terry in particular because it allows his Super Special Moves to cancel reliably from tilt attacks. Since only part of the commands needs to be inputted before the attack connects, this gives the Terry player a lot more control; if the attack used prior doesn't give a favorable situation for the special, the player simply doesn't finish the input. Buster Wolf's input also allows for Burning Knuckle to be used instead should the situation call for it. Overall, Renda canceling is an essential part of Terry's kit.

Command Orientation Input Locking

Command orientation input locking (often abbreviated as COIL, sometimes known as COIL charging) is an advanced technique introduced in Super Smash Bros. Ultimate. It involves exploiting a quirk in the way the game reads controller inputs to trick it into thinking that the player is moving in two directions at the same time. Because of this, while COIL is technically performable with every fighter, it's only truly useful for Ryu, Ken, Terry and Kazuya, where the first input of a command input or charge motion is available to them at all times, making said inputs easier to perform. Terry especially benefits from this technique by being able to run up to an opponent and perform an invincible Rising Tackle without holding down for 24 frames or charge partitioning. The only disadvantage to COIL, while significant in many scenarios, is that the attack button ceases to function while the C-Stick is held, making normal attacks unusable.

Before performing this technique, the player needs to ensure that their C-Stick is set to tilt attacks instead of smash attacks. The player then needs to hold the control stick in a certain direction, then hold the C-Stick in the same direction. Then, the player needs to let go of the control stick while still holding the C-Stick. For example, if the technique is done correctly and both sticks are held down followed by the control stick being released, the C-Stick will trick the game into thinking the control stick is still down.

A variant of this technique, known as Double Tap Command Orientation Input Locking (DTCOIL), has a slightly different activation method. After holding down on the analog stick, the player should quickly tilt the C-Stick twice, making sure that only one tilt attack comes out, and then continuing the technique as normal. Two tilt attacks mean the activation did not work. If done correctly, the direction will still be locked in and the A button will function, circumventing the issue with normal COIL.

Origin

Kazuya executing the Electric Wind God Fist in Tekken 5, a prime example of a "just frame" move.

Command inputs can be traced back to the 1987 arcade game Street Fighter. In that game, the player can access the Hadoken, Tatsumaki Senpukyaku, and Shoryuken with their respective inputs. There was a very strict window to activate, but all moves did massive amounts of damage to compensate. Players complained that the activation window was too strict which led to inputs being "eaten" and the controls feeling inconsistent. Capcom listened to these complaints and decided to make special moves easier to perform at the cost of damage for Street Fighter II. Takashi Nishiyama, creator of Street Fighter, also listened to these complaints after moving to SNK and created Fatal Fury. These two games laid the foundation for all fighting games in the future, and the inputs introduced are now commonplace across the genre.

Negative Edge is primarily seen in traditional fighting games, particularly Street Fighter. The term "negative" refers to the release of a depressed button, and for this reason, it sometimes goes by names such as "Button Up". Since its inception, games like Marvel vs. Capcom and BlazBlue adopted it for accessibility purposes. Releasing a button hold can trigger a special move when the motion is performed the same way as pressing a button can, but without the risk of throwing a move out.

Tiger Knee got its name from Sagat's "Tiger Knee" (↓ ↘ → + ↗ + Kick). First usable in Street Fighter II: Championship Edition, his first playable appearance, the move involves using a jump input (↗) to perform. As is in Ultimate, it is performed by using the command on the ground and doing the final input when airborne. While Sagat himself had no use for the technique, the input itself later became useful in other fighting games—particularly Guilty Gear—allowing for aerial versions of moves to be used extremely close to the ground. Because of this, moves utilized through this bypass are referred to as being "Tiger Kneed".

The Crouch Dash was first introduced in Tekken as an exploit of the physics engine where some fighters are able to slide forward a considerable distance after performing a certain technique. It was well received by the community upon discovery and has appeared in every major release since. It remains relevant today because not all playable fighters are able to use the technique, making it an valuable tool to those that do have it. The technique is also know colloquially as a "wavedash" due to the move activating in distinct phases, or "waves". The Smash version of the wavedash derives from this move, as it's similar in appearance and functionality.

"Just frame" is a Tekken term primarily associated with the Electric Wind God Fist, but is also used in games like Soul Calibur. It describes moves or actions that require a frame perfect input which cannot be buffered, though there are sometimes ways to make it easier depending on the game and character being used. A lot of the time, these inputs are defined by pressing a direction and button on the same frame, but this isn't always the case. These moves are typically very rare but extremely rewarding, often drastically increasing the skill required to utilize a character. In Smash, Kazuya's Electric Wind God Fist has a 2-frame window rather than 1-frame, making it somewhat easier to execute, and not necessarily a "just frame" attack in the traditional sense.
