Action Command

An action command (also known as a Timed Hit or a Timed Attack) allows a character to do significantly more damage to an enemy than with a normal hit. Often, action commands occur when the player presses the button right before the party member hits his opponent. Action commands are also used for defense; If the player presses the Guard button at the moment an enemy's attack hits, the character receives less damage or even counters the attack in some games.

Super Mario RPG: Legend of the Seven Stars
The action commands were originally called "Timed Hits" in Super Mario RPG: Legend of the Seven Stars, and are the key to success in the game. They are used both to increase damage dealt by the party's attacks and decrease damage done to the party by physical attacks. Timed Hits do not actually increase any statistics; they only serve to modify the damage after it is calculated.

There are actually two different levels of Timed Hits; one for timing the command "close" and one for timing it "perfectly". For the party's physical attacks, most Timed Hits are activated by pushing any button right before the attack lands. If an attack is timed close, the damage is increased by 50%, but if it is timed perfectly, the damage is doubled. Any Timed Hit with a physical attack will never miss.

For the party's special attacks, more variation is seen in the commands. Generally, any special attack which requires a single button press will increase damage (or healing) by 25% if timed close or 50% if timed perfectly. Other commands (push button repeatedly, hold  button, rotate the ) increase damage in other ways. For some attacks, good timing will increase the attack's range from one enemy to all of them.

Timed Hits are also used to avoid or reduce damage done by certain attacks. Only physical attacks may be blocked in this manner, and even some of those are unblockable. For those attacks which are blockable, a Timed Hit is usually activated by pushing any button right before the enemy attack lands. If the command is timed close, the character will only receive half damage, and if it is timed perfectly, the character will receive no damage at all, completely avoiding the attack. For attacks that cause instant death, a normal timed hit will leave the character standing with only 1 HP (and a perfect one will avoid it, causing no damage).

Paper Mario
In Paper Mario, Twink gives Mario the Lucky Star, a special pendant from Peach that allows the plumber to perform action commands. This artifact proves useful in the upcoming battle against a Magikoopa; a fight that occurs after Mario visits Shooting Star Summit for the first time. The Dodge Master badge makes performing action commands slightly easier. Some other Badges can alternate the damage blocked or delivered: The Damage Dodge badge increases the amount of damage blocked by Mario's Guard action command. The All or Nothing badge increases the attack power if the action command was performed successfully, otherwise the attack(s) do(es) not do any damage.

Paper Mario: The Thousand Year Door
In Paper Mario: The Thousand-Year Door, action commands (capitalized as Action Commands) reappear, and Stylish Moves are introduced. These allow Mario to recharge his Star Power faster. They can be performed from the start of the game, but have more effect when an audience appears to watch Mario's battles after visiting the Thousand-Year Door for the first time. The All or Nothing and Damage Dodge badges return with the same effects, while new badge Damage Dodge P badge works the same way as Damage Dodge except it is for Mario's partner. The Simplifier badge is introduced, which makes action commands easier, but reduces the star power gained from them. The Unsimplifier badge is also introduced which does the opposite.

Super Paper Mario
In Super Paper Mario, action commands are not used in battle; rather, they are done when using items. These action commands usually implement Wii Remote pointing and shaking. Stylish Moves reappeared in the game.

Paper Mario: Sticker Star
Action commands return in Paper Mario: Sticker Star, where they are used the same way they were in the previous installments. However, only is actually used while performing them. As such, some action commands that originally require moving the Control Stick have been changed, such as the hammer. Action commands can also be used with "Thing" Stickers for a better effect. Some require button-mashing while some require precise timing, such as the Cat-o-Luck. The Touch Screen can also be used as a substitute for.

Paper Mario: Color Splash
Action commands make another return in Paper Mario: Color Splash, behaving the same way as in Sticker Star. Only is used. Action commands can be practiced in the Action Command Dojo.

Mario & Luigi series
In the Mario & Luigi series only, Mario and Luigi can entirely avoid getting hit by enemy attacks by using the action command. They can jump over or on enemies or hit them or their projectiles with hammers to prevent them from attacking.

Mario & Luigi: Superstar Saga / Mario & Luigi: Superstar Saga + Bowser's Minions
In Mario & Luigi: Superstar Saga, Mario uses and Luigi uses  to attack and dodge. Action commands are used to double the damage of attacks. For jump attacks, the player must press the appropriate button when the respective brother lands on the enemy. For hammer attacks, the player must press the appropriate button when the hammer shakes. For hand attacks, the player must press the appropriate button when the attack is fully charged.

When using Bros. Attacks, the player must press the appropriate button at the right moment so the attack can deal more damage at the climax of the attack. If the right button is not pressed in time, or the wrong button is pressed, the move will end up dealing less damage or outright end prematurely without any more damage being done (in the case of the Advanced Chopper Bros. and Knockback Bros.).

While defending against enemy attacks, Mario and Luigi will either jump (pressing either or ) or use their hammers (holding down either  or ; though holding down the button for too long will cause the hammerhead to fall off) to counterattack. When using jumps, the brothers can jump over enemies by pressing their respective buttons to avoid taking damage or even stomp on them to deal damage. When using hammers, the brothers can either hit enemies when they directly attack, and knock enemy projectiles back at them to deal damage.

In the game's 3DS remake, Mario & Luigi: Superstar Saga + Bowser's Minions, the jump and hammer action commands are similar to those in future installments after Mario & Luigi: Bowser's Inside Story.

Mario & Luigi: Partners in Time
In Mario & Luigi: Partners in Time, Baby Mario and Baby Luigi use and  respectively when attacking. Using jumps and hammers to (counter)attack remains the same as in the previous game when the brothers are alone, though when fighting with all four together, the action commands are different. When using jumps with the baby bro with the adult bro, pressing the appropriate baby brother's button will cause them to jump off of their respective adult bro so that the latter can jump on the enemy, dealing two hits to the enemy, which deals more damage than a regular jump. When using hammers, the player can press the adult bro's button to lift up the baby, then press his baby button so the baby can hammer the enemy.

When using some Bros. Items (mostly those which can be used with only two characters) with all four characters, the player can use the baby bro's button to deal more damage to the enemy (ex. pressing the baby bro's button when using Green Shell will cause the attack to deal more damage).

Mario & Luigi: Bowser's Inside Story / Mario & Luigi: Bowser's Inside Story + Bowser Jr.'s Journey
In Mario & Luigi: Bowser's Inside Story and its 3DS remake, Mario & Luigi: Bowser's Inside Story + Bowser Jr.'s Journey, Mario and Luigi use the same buttons from previous installments. However, the jump and hammer action commands are different; when jumping on enemies, by pressing the appropriate brother's button, they can jump on the enemy again, similar to Mario & Luigi: Partners in Time. When using hammers, pressing the button when the brother rears back enough determines how much damage is dealt to the enemy. Counterattacking action commands are the same as in past games.

Bowser uses the and  for his action commands during normal battles depending on what move he uses; pressing  for punching depending on how far Bowser rears back, similar to the bros' hammer action command and holding down  when exhaling fire to deal rapid damage). When using Special Attacks, Bowser uses the stylus for his action commands. During giant battles, Bowser uses the stylus for punching and the microphone for his Fire Breath.

Mario & Luigi: Dream Team
In Mario & Luigi: Dream Team, the jump and hammer action commands are similar to Mario & Luigi: Bowser's Inside Story's action commands, though when counterattacking with hammers, the player can hold down the button indefinitely without the hammerhead falling off.

Mario & Luigi: Paper Jam
In Mario & Luigi: Paper Jam, the new playable character, Paper Mario uses to do action commands such as copying himself, using Trio Attacks, and perform the jump and hammer commands that the normal Mario Bros use, though it is done in a different fashion; depending on how much copies Paper Mario has made, it allows him to jump on a single enemy multiple times and hammer multiple enemies at the same time.
