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   /Stop  
|
The CPU will not move, barring some exceptions:
|
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 / Run
|
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/ Control
|
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 |
