List of CPU modes

CPU modes are different sets of AI behaviors used in different games throughout the series. Some of these are only accessible through use of the debug menu in Melee.

Name	Description	Availability	Debug name (Melee)
Attack	The CPU behaves normally, throwing out attacks and maneuvers. 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 aggresive at low levels.	Versus mode, various single-player modes, Training mode	CPTP_NORMAL
Stand (SSB, Melee), Stop (Brawl, Smash 4)	The CPU will not move, barring some exceptions: It will still attempt to recover if hit away from the stage, use an edge recovery or floor recovery when necessary (in SSB, the CPU will always wait until the maximum length for the latter case, then use a floor attack), and get 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 will use Transform periodically if not attacked, allowing players to practice against her alter-ego Sheik. Said character will also use Transform in this way. In Brawl, it 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. Other than this, it retains the same properties as "Stand".	Training mode, Event 19: Peach's Peril (Melee)	CPTP_WALK
Evade (Smash 64, Melee), Run (Brawl, Smash 4)	The CPU will actively avoid interaction with the player. Other than this, it retains the same properties as "Stand".	Training mode	CPTP_ESCAPE
Jump	The CPU will constantly single jump. Other than this, it retains the same properties as "Stand". In Smash 4, the CPU will also fast fall after every jump.	Training mode, Event 21: Ice Breaker (Melee)	CPTP_JUMP
Human (Melee), Control (Brawl, Smash 4)	The CPU is controlled by human players.	Training mode (Melee, Brawl, Smash 4 only)	CPTP_MANUAL
Nana	The default mode for the partner Ice Climber, so that he/she follows the leader, attacks with the leader, etc.	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
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
Cooperate	Causes the CPU to follow the player and attack them.	Debug menu (Melee only)	CPTP_COOPERATE
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
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
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
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
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
