Editing List of flaws in artificial intelligence (SSBB)

{{ArticleIcons|ssbb=y}}
The following is a list of flaws in the [[artificial intelligence]] of ''[[Super Smash Bros. Brawl]]''.

<!-- READ THE FOLLOWING GUIDELINES BEFORE ADDING ANY EXAMPLES:
1. Avoid adding very specific, situational instances that rarely, if ever, show up, where a computer player may not perform optimally. If you have to specify what level the CPU is, the character, the stage, what the CPU is attempting, and even the exact location on the stage, do not add it. Also do not add examples that require nonstandard gameplay, and do not add examples that you have to write a small guide to replicate.
2. Suboptimal play by the CPU in general does not constitute an AI flaw. For something to be considered an AI flaw, it has to be a repeated behavior by the AI that directly hinders a CPU's performance regardless of outside circumstances.
3. Per the previous guideline, a potential example must be a behavior by the CPU that it will nearly always repeat when the circumstances leading to the example occurs.-->

! Category !! Description !! Character 
|-
| rowspan=5 align=center|Attack choices
| When dashing a long distance towards the player, CPUs often attack them with a basic [[dash attack]], rarely using dash grabs or aerial attacks instead, making their [[approach]] easy to punish. Similarly, they tend to [[grab]] when starting to [[walk]] close to the player.
| All
|-
| When at a moderate distance from a foe, most CPUs often jump before shooting [[projectile]]s, even if these are fired in a straight horizontal trajectory, such as [[Blaster]] or [[Charge Shot]], causing them to miss if the foe just stays on the ground.
| All
|-
| CPUs that launch an opponent upwards will just stay on the ground waiting for them to come down, spamming [[up tilt]]s and [[up smash]]es as they get near, which can be easily dodged, even when going airborne and responding with aerials is a better option.
| All
|-
| When the player and a CPU with a [[charge]]able projectile are on opposite sides of a stage, the CPU often charges and fires it constantly regardless of whether the player can [[absorb]] or [[reflect]] it.
| All
|-
| CPUs have generally poor edgeguarding abilities, simply standing on the edge of the stage and spamming weak projectiles such as {{SSBB|Mario}}'s [[Fireball]] instead of attacking offstage, while rarely taking advantage to do the same with characters that have stronger and more optimal projectiles for edgeguarding, such as {{SSBB|Samus}}.
*Only a few AI-controlled characters, mostly those with multiple midair jumps such as Kirby, leave the stage to intercept a recovery with an attack, normally a meteor smash (down aerial in Kirby's case). Other characters with meteor smashes only use them if they were previously away from the stage, and simply stand on the edge waiting for the player if they don't have any projectiles.
| All
|-
| rowspan=14 align=center|Recovery
| CPUs never avoid or fight off [[edgeguard]]ers during their recovery, making them much easier to KO than human players.
| All
|-
| While CPUs in ''Melee'' could [[meteor cancel]] to a moderate degree, CPUs never meteor cancel in ''Brawl'', sustaining a meteor smash's full knockback before attempting recovery. This results in meteor smashes KOing CPUs at much lower percentages than they can KO human players.
| All
|-
| CPU Luigi never uses [[Luigi Cyclone]] to recover, and never rises with the move in any other situation.
| {{Head|Luigi|g=SSBB|s=16px}}
|-
| A CPU Peach going over the stage with [[Peach Parasol]] will constantly cancel and reinitiate the move if a player is nearby, instead of simply falling all the way down or grabbing a [[ledge]], leaving herself open to punishes.
| {{Head|Peach|g=SSBB|s=16px}}
|-
| CPU Diddy Kong, Zelda, and Lucario use their up specials after their midair jumps to recover even when above ground level, without aiming for a ledge in the case of the latter two, leaving themselves open to powerful attacks as they land on the stage.
| {{Head|Diddy Kong|g=SSBB|s=16px}} {{Head|Zelda|g=SSBB|s=16px}} {{Head|Lucario|g=SSBB|s=16px}}
|-
| CPU Yoshi never uses [[Egg Throw]] to recover.
| {{Head|Yoshi|g=SSBB|s=16px}}
|-
| CPU Kirby at high levels recovering while above ground level always uses a [[forward aerial]] after each of his midair jumps until he gets back to the stage; while this makes him the only CPU to actually attack edgeguarders, the whole process still eventually becomes easy to predict and counter.
| {{Head|Kirby|g=SSBB|s=16px}}
|-
| CPU Meta Knight never uses [[Mach Tornado]] nor [[Drill Rush]] to recover, and often uses [[Dimensional Cape]] to recover instead of Meta Knight's other superior recovery options.
| {{Head|Meta Knight|g=SSBB|s=16px}}
|-
| When using their up specials during recovery while above ground level, CPU Fox and Falco will aim for nearby onstage foes instead of a safe ledge, leaving themselves easily punishable.
| {{Head|Fox|g=SSBB|s=16px}} {{Head|Falco|g=SSBB|s=16px}}
|-
| CPU Ness and Lucas always hit themselves with [[PK Thunder]] in the same upward diagonal trajectory when recovering, even if using such a trajectory results in them failing to make it back to the stage while a more desirable trajectory would have allowed them to recover successfully. This is especially noticeable on {{SSBB|Final Destination}}, as Ness will often not make it back to the stage when using PK Thunder to recover (when recovery is possible), while a Lucas will often launch himself underneath the stage's lips.
*CPU Lucas also never uses his [[grab aerial]] for recovery.
| {{Head|Ness|g=SSBB|s=16px}} {{Head|Lucas|g=SSBB|s=16px}}
|-
| CPU Ice Climbers never use [[Squall Hammer]] to recover even when their partner has been KO'd, guaranteeing a failed recovery if their midair jump doesn't make it back to the stage.
| {{Head|Ice Climbers|g=SSBB|s=16px}}
|-
| CPU Ike doesn't use [[Aether]] unless he is directly underneath a ledge. This can cause him to get KO'd without trying to recover or waiting too late to use Aether and failing a recovery that was possible.
*CPU Snake exhibits similar behavior using [[Cypher]], often choosing to use it too late and getting KO'd.
| {{Head|Ike|g=SSBB|s=16px}} {{Head|Snake|g=SSBB|s=16px}}
|-
| After CPU Mr. Game & Watch fails to recover with [[Fire]], he repeatedly uses [[Judge]] until the bottom blast line is crossed. While not necessarily problematic, there are instances where if a CPU Mr. Game & Watch reaches the apex of Fire and ends up short of the stage but in distance of reaching the ledge, the CPU will decide to use Judge too soon, causing him to miss the ledge and get KO'd.
| {{Head|Mr. Game & Watch|g=SSBB|s=16px}}
|-
| CPU R.O.B. never attacks or air dodges after using [[Robo Burner]] until he reaches the ground, grabs a ledge, or is hit by an attack.
| {{Head|R.O.B.|g=SSBB|s=16px}}
|-
| rowspan=2 align=center|Shielding & Dodging
| After a CPU KOs a player, while the player has invincibility frames after respawning, the CPU always runs away and jumps onto a platform if there is one nearby, fleeing to others if the player comes near, without trying to dodge any attacks.
*On stages without platforms like {{SSBB|Final Destination}}, CPUs instead constantly [[roll]] towards the nearest edge, even when jumping or sidestepping are better options to dodge foes, making them predictable and punishable.
| All
|-
| High-level CPUs almost always [[air dodge]] as soon as possible when launched in [[tumbling]] state, which can be easily exploited to get followups.
| All
|-
| rowspan=8 align=center|Other
| When the player grabs a ledge, CPUs will stand still at a distance away from the ledge for some seconds before pursuing the ledge hanging player, doing so even after their invincibility wears off.
| All
|-
| When a CPU, regardless of level, is hit near the upper [[blast line]] while above an elevated platform, it will fall straight down until reaching the ground after knockback is finished, while making no attempt to dodge or counterattack a pursuing player.<ref>http://www.youtube.com/watch?v=D9nursdpKIw</ref>
| All
|-
| When hit by an [[electric]] hitbox, a CPU may randomly [[DI]] up or down, more often DIing down, which can result in instances of an attack with an electric hitbox KOing them when the computer player would have survived otherwise.
| All
|-
| When grabbing edges, CPUs frequently choose to jump from them, instead of using other options like getting up with a roll or [[edge hop]]ping, causing them to be easily punishable.
| All
|-
| CPUs never attempt to [[edgehog]] if they're on the stage; they never leave the stage to grab a ledge to prevent another character from grabbing it. They do, however, remain on a ledge if a recovering character is also trying to grab it, but only if the CPU in question was attempting to recover as well.
| All
|-
| When afflicted by Snake's [[down throw]] near an edge, CPUs will always roll toward the nearest edge the instant they can make a move, regardless of their level. This allows Snake to infinitely grab and use the throw on them, and get an easy KO afterward.<ref>http://www.youtube.com/watch?v=Lywfn1gCgJs</ref>
*If the throw is done in a soft platform without grabbable edges, CPUs will instead always use a floor recovery attack, also leaving them open for another grab.
| All
|-
| CPUs [[Floor recovery|floored]] by {{SSBB|Ganondorf}}'s [[Flame Choke]] always linger on the ground for some time before inputting a getup option, instead of acting the soonest they can, allowing players to always get followups out of Flame Choke that wouldn't be true on a human player.
| All
|-
| CPUs ignore when [[Team Attack]] is on, carelessly using powerful moves like [[smash attack]]s even if there are teammates with high damage near them, thus KOing them. When accidentally grabbing teammates, they will also still [[pummel]] and throw them.

===Character Specific===
{| class="wikitable sortable"
|-
! Character !! Description
|-

| {{Head|Fox|g=SSBB|s=20px}}{{Head|Falco|g=SSBB|s=20px}}{{Head|Wolf|g=SSBB|s=20px}}
| CPU Fox, Falco, and Wolf will often use their reflectors in an attempt to block Kirby’s aerial [[Stone]] attack, despite it not being a projectile, thus causing them to get hit. The higher their level, the more often they’ll attempt it. They will also do this with Jigglypuff’s [[Rollout]], but it is at least somewhat effective at stopping it since it isn’t invincible.
|-

| {{Head|Bowser|g=SSBB|s=20px}}{{Head|Charizard|g=SSBB|s=20px}}
| CPU Bowser and Charizard never hold [[Fire Breath]] and [[Flamethrower]] (respectively) beyond their initial length. Additionally, they tend to [[B-reverse]] these moves when used after a jump even if the foe is in front of them, rendering them ineffective and making it easy to punish them.
|-

| {{Head|Diddy Kong|g=SSBB|s=20px}}
| CPU Diddy Kong never attempts to pick up his [[Banana Peel]]s, even when he intentionally spawns them.
|-

| {{Head|Ganondorf|g=SSBB|s=20px}}
| CPU Ganondorf often attempts to edgeguard foes with his [[Warlock Punch]], even when the said move is extremely slow and thus impractical for edgeguarding, as the player can simply go above Ganondorf, or grab the ledge and hit him out of it.
|-

| {{Head|Zero Suit Samus|g=SSBB|s=20px}}
| CPU Zero Suit Samus never picks up her [[Power Suit Piece]]s intentionally.
|-

| {{Head|Pikachu|g=SSBB|s=20px}}
| CPU Pikachu tends to spam [[Thunder]] on the edge of the stage when the player is recovering, even when such a tactic is ineffective for edgeguarding, as the player can just grab the ledge from a safe position or hit Pikachu out of the move.
|-

| {{Head|Ness|g=SSBB|s=20px}}{{Head|Lucas|g=SSBB|s=20px}}
| When the player stays away from them for a long time, CPU Ness and Lucas will try to attack with [[PK Thunder 2]], leaving them extremely vulnerable.
|- 

| {{Head|Ice Climbers|g=SSBB|s=20px}}{{Head|Ike|g=SSBB|s=20px}}
| CPU Ice Climbers and Ike often [[buffer]] their [[down aerial]]s near a ledge, also [[fastfall]]ing in the case of Ike, leading to them [[self-destruct]]ing.
|-

| rowspan=2|{{Head|Marth|g=SSBB|s=20px}}
| CPU Marth often uses [[Dancing Blade]] to attack the player at close distance, also using it most of the time after a [[short hop]] when approaching.
|-
| CPU Marth tends to charge [[Shield Breaker]] on the edge of the stage to edgeguard players, even though the attack can be easily avoided and interrupted.
|-

| {{Head|Captain Falcon|g=SSBB|s=20px}}
| CPU Captain Falcon often uses [[Falcon Punch]] at inappropriate moments, such as when approaching or at a close distance from a hostile player, leaving himself open to powerful punishes. At first, this caused many players to believe he could be "taught" to spam the move.
*He also uses it in an attempt to edgeguard foes in the same way CPU Ganondorf does, which can be easily avoided.
|- 

| {{Head|R.O.B.|g=SSBB|s=20px}}
| CPU R.O.B. tends to use [[Gyro]] while a disc is still out, even though it cannot use it until the disc fades away.
|-

| {{Head|Snake|g=SSBB|s=20px}}
| When a CPU Snake sticks a [[C4]] on an opponent, he always runs a small distance away and uses Cypher, then detonates the C4 after. This makes him extremely vulnerable, predictable, and [[punish]]able. If attacked out of the Cypher, he simply runs away a short distance and then detonates the C4.
|-

| {{Head|Sonic|g=SSBB|s=20px}}
| CPU Sonic spams [[Spin Dash]] to approach the player from far distances.
|-

| {{Head|Marth|g=SSBB|s=20px}}{{Head|Lucario|g=SSBB|s=20px}}
| Marth and Lucario tend to use their counterattack moves randomly rather than at strategic moments.

! width=8%|Item !! width=92%|Description 
|-
| rowspan=3| [[File:SmashBallIconSSBB.png|40px|Smash Ball|link=Smash Ball]]
| After a CPU Luigi uses [[Negative Zone]], he will [[spam]] [[Fireball]] until the move ends, regardless of his level.
*CPU {{SSBB|Pit}} exhibits the same behavior with [[Palutena's Arrow]], spamming it during the effects of [[Palutena's Army]].
|-
| CPU Diddy Kong, {{SSBB|Yoshi}} and Sonic using [[Rocketbarrel Barrage|their]] [[Super Dragon|Final]] [[Super Sonic|Smashes]] have a tendency to behave rather eccentrically:
*They will mostly avoid pursuing players who are hanging onto ledges or in hard to reach areas. 
*They may get stuck against a wall while chasing human players, and stay there until the effect ends (unless the player(s) they are pursuing jumps or moves to another area). Occasionally, they will manage to get off of the wall on their own and continue the chase.
*They may standstill if the player is not within easy reach. Whenever they do this, they will only move if the player does.
*They may even stand still when on top of slippery or fragile platforms.
|-
| CPU {{SSBB|Fox}}, {{SSBB|Falco}} and {{SSBB|Wolf}} at low levels mostly self-destruct when using [[Landmaster]], especially if the target is hanging on a ledge. At high levels, they instead stay in place and repeatedly perform barrel rolls against opponents grabbing the ledge, which can be easily avoided by [[planking]].
*Additionally, they will never attempt to [[Star KO]] enemies above them by rising, only doing so accidentally when rising on small stages like [[Flat Zone 2]].
|-
| [[File:GooeyBombIconSSBB.png|40px|Gooey Bomb|link=Gooey Bomb]] [[File:C3.png|40px|C4|link=C4]] || CPUs with a Gooey Bomb or C4 stuck on them repeatedly shield and dodge until they fall off or explode.
|-
| [[File:HammerIconSSBB.png|40px|Hammer|link=Hammer (item)]] [[File:GoldenHammerIconSSBB.png|40px|Golden Hammer|link=Golden Hammer]] || Despite their better recognition of items, CPUs still experience several flaws when using the Hammer as in ''Melee'':
*They still tend to accidentally fall offstage when trying to attack a foe near a ledge and, when on an elevated platform, jump continuously in place even if the obstacle can be jumped over.
*They still chase foes when using a Headless Hammer or Golden Squeaky Hammer, and try to avoid players with such Hammers instead of attacking them.<ref>http://youtu.be/E_oOYwlz8iM</ref>
|-
| [[File:CrackerLauncherIconSSBB.png|40px|Cracker Launcher|link=Cracker Launcher]] || CPUs exhibit several problems when using a Cracker Launcher:
*They usually don't turn around while holding the item and don't drop the item if it still has ammo.
*Additionally, if their targeted player is not directly in front of them, they will usually fire the weapon off at a slow, constant rate without changing their trajectory, and step back between each shot.
|-
| [[File:TeamHealerIconSSBB.png|40px|Team Healer|link=Team Healer]] || CPUs holding a Team Healer always throw it towards their enemies, never towards their own teammates.
|-
| [[File:BobombIconSSBB.png|40px|Bob-omb|link=Bob-omb]] || CPUs never pick up Bob-ombs intentionally.
|-
| [[File:DekuNutIconSSBB.png|40px|Deku Nut|link=Deku Nut]] [[File:SmartBombIconSSBB.png|40px|Smart Bomb|link=Smart Bomb]] || CPUs throw Deku Nuts at opponents regardless of distance, even if the opponent is close enough to cause them to get stunned themselves. The same applies to Smart Bombs, which they often throw too close to opponents, getting caught in the explosion.
|-
| [[File:UniraIconSSBB.png|40px|Unira|link=Unira]] || When a player is crouching behind an Unira, a CPU will always try to walk into it before attacking, resulting in them taking damage repeatedly until the Unira disappears.
|-
| [[File:PoisonMushroomIconSSBB.png|32px|link=Poison Mushroom]] || CPUs will chase after Poison Mushrooms even though they give a fighter affected by one a disadvantage.
|-
| [[File:CapsuleIconSSBB.png|40px|Capsule|link=Capsule]] || CPUs that pick up a Capsule almost always throw it upwards into the air for no apparent reason (doing so even if no foes are above them), instead of simply throwing them forward or down to break it.
|-
| All || CPUs walk slowly against items that appear offstage in stages with walk-off blast lines, without just picking them up.

===Stage Related===
{| class="wikitable sortable"
|-
! Stage !! Description
|-
| Almost All || CPUs, even at level nine, tend to ignore stage hazards without dodging them, including powerful ones like the Ultimate Chimera in [[New Pork City]] or the enemies in [[Mario Bros.]], resulting in them getting fatally KO'd at a much faster rate than human players.
|-
| [[File:New_Pork_City1.jpg|60px|link=New Pork City]] [[File:SSB4U75m.png|64px|link=75m]] || CPUs have difficulty transversing large stages such as New Pork City, 75m and most [[custom stage]]s, where they will often scatter around instead of just approaching the player, and may even self-destruct crossing certain parts of the stages.
|-
| [[File:Mushroomy2.jpg|128px|link=Mushroomy Kingdom]] || In the underground version of Mushroomy Kingdom, CPUs repeatedly attack the blocks, usually ignoring the player even if items aren't on.
|-
| [[File:Delfino_Plaza.jpg|128px|link=Delfino Plaza]] || On Delfino Plaza, when the main platform reappears and starts to rise, CPUs usually stay on the old stage, which leads to them being lowered towards the bottom [[blast line]] to their deaths.
|-
| [[File:Hyrule_Temple.jpg|128px|link=Temple]] || CPUs have a difficult time getting out of the underground part of Temple when opposing players are on the upper part. This is especially noticeable with CPU Wolf<ref>http://youtu.be/a3Uus1Ql2xg</ref>.
|-
| [[File:Pirateship.jpg|60px|link=Pirate Ship]] [[File:Delfino_Plaza.jpg|60px|link=Delfino Plaza]] || CPUs never swim on Pirate Ship or Delfino Plaza, always jumping out of the water immediately to come back to the stage.
|-
| [[File:Port Town Aero Dive.jpg|128px|link=Port Town Aero Dive]] || On the first stop of Port Town Aero Dive after the start/finish line, when the main platform ascends, CPUs tend to run away to the sides of the stage and jump off them even if that causes them to be unable to reach the platform afterwards, self-destructing in the process.
|-
| [[File:Skyworld1.jpg|128px|link=Skyworld]] || On Skyworld, CPUs tend to aim for the moving platform below the stage when recovering, even it it's moving away from them, often causing them to fail their recoveries when they could have aimed for the stage's ledges instead.
