List of CPU modes

CPU modes are different sets of AI behaviors used by computer players in different games throughout the series. Several are intended for use in Training Mode, while other actions can only be seen performed in various Melee event matches. A few modes are only accessible through the use of Melee's debug menu.

Training Mode

Name	Description	Availability	Debug name (Melee)
Stand / Stop	The CPU will not move and will not make any inputs to defend itself or upon getting hit, barring some exceptions: It will still attempt to recover if hit away from the stage, use a standard floor recovery after being knocked down (in SSB, the CPU will always wait until the maximum length, then use a floor attack), use a ledge jump edge recovery when hanging onto a ledge, and jump off of revival platforms. When put to sleep in SSB, it will attack nearby foes right after the sleep ends. In Melee, a CPU Zelda or Sheik will use Transform periodically if not attacked, allowing players to practice against either alter-ego form. In Brawl, a CPU will still air dodge after being launched in tumbling state when set to high levels, and will participate in the WarioWare, Inc. microgames.	Training mode	CPTP_STAY
Walk	The CPU will walk back and forth across the stage. Upon encountering obstacles that it cannot traverse, the CPU will reverse directions. Other than this, it retains the same properties as "Stand".	Training mode, Event 19: Peach's Peril (Melee)	CPTP_WALK
Jump	The CPU will constantly single jump in place. In Smash 4, the CPU will also fast fall after every jump. Other than this, it retains the same properties as "Stand".	Training mode, Event 21: Ice Breaker (Melee)	CPTP_JUMP
Evade / Run	The CPU will actively run away from and avoid interaction with the player. Other than this, it retains the same properties as "Stand".	Training mode	CPTP_ESCAPE
Attack	The CPU will behave normally, throwing out attacks and maneuvers. The level of the CPU is chosen at the character select screen, and can only be adjusted afterwards in Brawl. If the player has placed multiple Training CPUs on the stage, they will be considered on the same team and will not attack each other. In Smash 4, CPUs set to this mode in Training spam projectiles and many approach attacks (such as Falcon Kick) more often than in other game modes, also being more aggressive at low levels.	Versus mode, various single-player modes, Training mode	CPTP_NORMAL
Human/ Control	The CPU will be controlled by human players using extra controllers. If multiple Training CPUs are placed on the stage, they will all need separate controllers. As with Attack mode, CPUs cannot hit each other.	Training mode (Melee onward only, excluding Smash3DS)	CPTP_MANUAL

Melee event matches only

Name	Description	Availability	Debug name (Melee)
Special Low Link, Special Low Samus	Causes the CPU to only use their down special move when set to Link and Samus respectively. "SPLW" is an abbreviation of "Special Low", which reflects that the character only uses their down (or "low") special. When this behavior is set to any other characters via the Debug Menu, they will constantly spam their down special in place, using even Counter, PSI Magnet and Rest, which they never use in any other situations.	Event 3: Bomb-fest (Melee), Debug menu (Melee only)	CPTP_SPLWLINK, CPTP_SPLWSAMUS
Freak	Causes the CPU to stay where they are, but attack when an opponent comes near.	Event 6: Kirbys on Parade (Melee), Debug menu (Melee only)	CPTP_FREAK
Item	Causes the CPU to attempt to grab all items that appear. Otherwise, the CPU is normal.	Event 7: Pokémon Battle (Melee), Debug menu (Melee only)	CPTP_ITEM
Event Zelda	Causes Zelda to transform into Sheik more often. It is presumed to stand for "Event Zelda".	Event 9: Hide 'n' Sheik (Melee), Debug menu (Melee only)	CPTP_EVZELDA
Only Item	Causes the CPU to only use items, as opposed to using any other attacks.	Event 37: Legendary Pokémon (Melee), Debug menu (Melee only)	CPTP_ONLYITEM

Melee debug menu only

Name	Description	Availability	Debug name (Melee)
Nana	The CPU will follow the player and attack with them. As the name implies, is the default mode for the partner Ice Climber.	With Ice Climbers, Debug menu (Melee only)	CPTP_NANA
Defensive	The CPU will only use defensive tactics, such as shields and rolls.	Debug menu (Melee only)	CPTP_DEFENSIVE
Struggle	Causes the CPU to attack the nearest opponent, regardless of whether they are a human or a CPU. This is different from normal CPU behavior because a normal CPU will dedicate its attention to human opponents, unless a CPU stands between it and a human, or if there are no human opponents in the match.	Debug menu (Melee only)	CPTP_STRUGGLE
Cooperate	Causes the CPU to follow the player and attack them.	Debug menu (Melee only)	CPTP_COOPERATE
No Action	Causes the CPU to do absolutely nothing. This is not to be confused with "Stand", in which the CPU will still attempt to recover if knocked off.	Debug menu (Melee only)	CPTP_NOACT
Air	Causes the CPU to use only short hops instead of full jumps, though it will also use them more often when approaching the player.	Debug menu (Melee only)	CPTP_AIR
