Artificial Stupidity/Video Games/Fighting Game

Examples of in  games include:


 * In the computer fighting game Big Bang Beat: 1st Impression, you have an energy meter which depletes as you attack, and disables most of your attacks when it drops low enough. You can recharge this meter using the classic SNK "stand still and hold down a button" method: However, you have to HOLD the button to charge. The computer, which IS limited by this bar as well, tends to TAP the button, meaning they charge with at best a tenth of the speed you do, and most of the time fail to charge at all. Thus, you can usually win any fight by turtling until the opponent's bar runs out, and then bashing him to pieces as he futilely tries to recharge.
 * Several recent WWE SmackDown! vs. RAW games exhibit problems during specialty matches, most notably the Elimination Chamber -- rather than fight normally, computer-controlled opponents will instead spend much of the match climbing up and down the chain rigging and corner chambers. Sometimes, rather than climb down, opponents will instead hurl their bodies off the chambers with diving attacks that almost always miss, inflicting upon them damage more grievous than the player-controlled character can effectively dole out. However, they do make up for this somewhat by constantly breaking pin attempts -- despite the fact that the Elimination Chamber is an elimination-style match and the computer, at least in theory, benefits from the elimination of other competitors just as much as the player does. Meanwhile, AI characters in the Royal Rumble mode have been known to eliminate themselves from the match by jumping onto an opponent outside the ring.
 * These problems have been resolved - the Royal Rumble having been overhauled, while the Elimination Chamber was fixed in that regard (though still tends to have one major glitch a year) - but now there are others. Three in particular come to mind; first, computers will about 50% of the time go running after any ladder that's outside the ring immediately after it's put there, which in a Money in the Bank match can get you alone in the ring with another ladder to try and climb up - if you do start climbing they will come back, but it does give you some precious seconds to give it a shot. Second, computers love to throw you into the corner and turn you around over and over and over again until you recover, rather than actually attack. And third, in a Scramble match computers will always move to break up any pins, even though on paper the only person who would be affected by it would be whoever the current champion is.
 * In defense of the Scramble match glitch, in the Real Life matches, superstars would often break up pins even though they did not gain or lose anything for doing so.
 * Despite being an SNK Boss on the last floor of the Tower of Souls, Algol in Soul Calibur IV has an exploitable AI: he tends to perform a low slash followed by a leaping low slash when he knocks your character down. If you happen to be lying on the edge of the arena, odds are he'll leap to his doom.
 * The Fighting Game Maker, MUGEN, being accessible to amateurs and highly popular, has AIs that fall everywhere on the scale. On the one hand, you have ones that make the official SNK Bosses look easy; on the other, somewhere out there, there's a Zero character with an AI so badly written, it will actually crash the game.
 * In counterpart, there are some characters (and AI patches for SEVERAL characters) out there with an AI so well-coded that makes it almost look like you're playing against a pro, averting this trope.
 * Killer Instinct Gold features an odd version including Glacius's Liquidize move: Oh higher difficulty matches most enemies read your moves and perform specific moves to keep you from starting combos. If you are all the way across the screen, Liquidize briefly, and simply remain still afterward, almost all opponents walk towards you until they are in range to do their specific counter-maneuver for Liquid Uppercut. No matter the opponent, their chosen move is always countered by Cold Shoulder, Rock-Paper-Scissors style. As long at it goes into a simple combo, they will rarely be able to do anything else. This actually gets EASIER to do the farther you go and the harder the setting.
 * In the old Ranma1/2 fighting game Super Hard Battle, final boss Herb invariably responds to projectiles by jumping over them and towards the opponent. Therefore, defeating him is as simple matter as using a projectile, hitting him with an anti-air attack (knocking him back to almost the exact spot where he started), and repeating.
 * The AI in Jump! Ultimate Stars for the DS is the worst fighting AI short of MUGEN. The AI is so bad that most players recommend that people DO NOT BUY THE GAME if they don't have access to Wi-Fi. The AI will kill itself more often than you can kill it! The AI in JUS will jump to their death repeatedly in just about any stage with a pit in it, even after they've just respawned!
 * Let's not forget status effects. Auto-Run and Burn will cause the AI to do nothing but run straight ahead (even into a pit or wall) and Confusion makes them do the same thing but in reverse. Blind, Guard Seal and Movement Seal (which only seals your directional movement and jumping, not attacking or blocking) will cause the AI to do nothing but stand still, not even blocking.
 * Then there's their attacks. In a game with 50+ playable characters and over 200 Support characters, it seems that the best strategy the AI can come up with on any difficulty is to randomly mash the "touch" attack, launch Support characters at random intervals (even where it would be completely stupid to do so, like setting down a healing support when they're standing right next to you, and not picking it up) and repeatedly throw out projectiles and Specials with no regard to distance or actual effectiveness.
 * The game can also fall into The Computer Is a Cheating Bastard territory on Hard mode, where the AI will automatically block the second you touch any attack buttons. It still can't kill you, and still kills itself repeatedly, though.
 * Your partner AI in the Super Smash Bros. has the intelligence of a garden slug on rhino dookey while the enemy AI are vicious tigers. Unfair, ain't it?
 * In Melee there was something called the "flipper dance": when fighting a single computer opponent, pick a stage with decent sized flat base and no movement affecting gimmicks, such as Final Destination, take a flipper and just throw it straight so that it lands at walking height between you and the opponent and just stand still a few feet behind it. The enemy will slowly walk towards you, then, right before hitting the flipper, will dodge roll backwards, then start walking towards you again, rinse and repeat until the flipper expires. It never gets old to watch the computer completely forget it can jump.
 * They're similarly unable to comprehend bumpers in Brawl.
 * In the same game, some characters like Captain Falcon and Ganondorf will randomly throw out their strongest, but slowest attacks while you're nowhere near them, presumably hoping you'll just stumble into them. A player using Roy can have a field day with them thanks to his Counter special.
 * Some characters, like Mr. Game and Watch and Yoshi were particularly dumb, as they'd invariably approach you by performing a dashing attack or grab that would whiff if you just stood still, leaving themselves wide open for an attack. Therefore, it was possible to beat them without even moving.
 * Also, characters with an ascending Up B attack like Captain Falcon and Mario, would almost always use that move if you jumped directly above them from a distance. This would either leave them wide open for a retaliatory attack, or if they were standing at the edge of the level, potentially send them flying to their doom.
 * In Brawl, the AI can navigate custom stages fairly well...unless it has spikes. CPUs don't quite seem to get the idea that spikes are bad, and it's not uncommon to see a CPU work his damage up hundreds higher than normal just bouncing on spikes.
 * Trampolines also. If you're on one side of a wall and the CPU is on the other, it will spend tons of time trying to jump over the wall, even if it's too high, despite there being a spring behind it which it could use to jump over the wall.
 * It has trouble with the falling blocks, too - it doesn't seem to have any foresight, so it will often remain standing on a block until it's too low to reach the rest of the stage.
 * They do realize the spikes are dangerous, when they're about one inch away from them and unable to do anything about it. Same with a few dangerous items, where they constantly approach the item only to roll away from it just before they get hurt.
 * In general, they have trouble with the idea that stages aren't always completely static. If the bottom of the stage is occupied by horizontally moving platforms, the computer-controlled characters will miss the platforms by a mile every single time.
 * Throughout the series, no matter how high you set the computer's skill level at, they always make the mistake of walking onto motion sensor bombs no matter how visible they are.
 * Made funnier in Brawl by the fact that they'll briefly hesitate before doing so, as if contemplating whether it's a good idea or not.
 * Let's not forget Luigi's infamous glitch in Melee, where he would use his side special (which propels him horizontally as a missile) whenever he fell off the stage and usually fail. If he had used his up special (a big vertical jump) he would have survived, but the programming doesn't let him do so. The problem was that Luigi had two recovery moves, but the AI could only be taught one per character. This was fixed in Brawl.
 * In Melee, if you select Ness as your opponent, and select Jungle Japes, if you don't move at all Ness will perform a double jump straight into the river, regardless of what the AI level is (however, if you set the level to a higher one, he'll attempt to use PK Thunder, which ends up hitting the platform you are standing on). This was fixed in Brawl where he does the exact same thing, but manages to grab onto the edge of the platform and climb up.
 * In Melee, if you play on Hyrule Temple and select any number of Kirbys as your opponent, you could effortlessly trick them into turning to rocks directly above the hole that goes down to the lower levels of the stage, in which case they would slide all the way down the slopes and into the pit.
 * Even a level 9 CPU Marth can act extremely stupid in Melee. Select him as an opponent and play on the Jungle Japes stage. Knock him off the stage once, and while he's respawing, quickly get onto the platform at the far right of the stage. Your opponent should jump toward you each time he respawns, only to perform his up+B special away from you, killing himself.
 * In Brawl, the AI will always perform an air dodge immediately after being struck in air, or being hit into the air, oblivious to the fact that there's a brief window of vulnerability as one ends. It's quite easy to juggle them to death by simply timing your attacks.
 * In Melee, some giant characters you go up against in one-player mode (specifically Yoshi) may start the match off by leaping off the edge of their platform into a Bottomless Pit, ending the fight in less than 5 seconds. It happens in Brawl too, but less often and usually a little later into the fight. Metal characters also suffer sometimes; they drop faster but the AI doesn't always acknowledge that.
 * In one Street Fighter game, the AI character of Balrog would react to many moves by trying to jump over them and punch you. E. Honda's hundred hand slap would cause him to keep jumping into it until he was dead.
 * It gets funnier: In every iteration of SFII prior to Super SFII, Balrog/M. Bison would routinely perform his array of dash punches and hardly anything else. This would lead to him being easily countered by a sweep attack or projectile attack. Similarly, Zangief could be defeated by simply backing into a corner and repeatedly jump kicking him in the head.
 * Some enemy AI is sufficiently designed to be ridiculously exploitable. For instance, against Ken in Street Fighter Alpha 3 or the Capcom vs. SNK Millennium Fight 2000 games, jump backward and attack. If he has enough meter, he will do his Shoryureppa and miss completely. Similarly, the final form of Bison in Alpha 3 can be easily baited with a jab, against which he will either teleport behind you (easy to combo or super) or crouch for a few seconds and throw a fireball (easily jumped and comboed).
 * Rise of the Robots was touted in a pre-release trailer for the game as the first fighting game where the enemy adapts to your fighting style and changes its tactics based on how you come at it. This, however, is a lie, as every single opponent, up to and including the final boss, can be defeated simply by moving forward and kicking it into a corner.
 * In the Fighting Game spinoffs of Touhou, the AI has a tendency to drop its block at all the wrong times and perform other stupid things:
 * Komachi's "Dial-A" combo takes quite a long time to be fully executed, so the AI always blocks the first 3 hits and usually fails to block the last overhead slash.
 * The AI also sometimes falls for Spell Cards (supers) right after blocking a long combo.
 * Sometimes, when using Youmu, the AI will attempt to follow up a combo with a special whose only purpose is reflecting bullets and does not hit the enemy.
 * The AI frequently does not use Spell Cards at moments where it could chain into them, possibly even winning them the match. Sometimes, even with a five-cost card ready, they do not use it throughout the match!
 * The AI does not know how to switch cards and/or use skill cards to move a super into position. If a skill/system card is ready to be used, they will not use a single super throughout the match!
 * The computer opponents in Windy X Windam almost never block anything, even at the highest difficulty setting. In most cases, this allows characters with launcher attacks to lift the opponent into the air and juggle them until they die.
 * Unless they're lying on the ground, they won't think to block or dodge multiple-hit ranged attacks (especially super moves, which activate after a two-second delay).
 * In the higher difficulty levels of Dragonball Z Budokai 3, AI opponents are much more likely to try and use ultimate moves on you, which are difficult to connect against a moving target and a huge drain of ki. If you go purely evasive once they activate hyper mode, you can usually wait for them to run out of ki, then utterly thrash on them while they recover. If you get good at this, the harder levels can be easier than the normal ones.
