Unofficial Pokémon which only appear through the use of glitches.
The most popular and well known "glitch" Pokémon, and a contender for one of the most (in)famous video game bugs known. Missingno. exists due to the way Pokémon handles a tutorial early in the game. When an Old Man in Viridian City shows the player how to catch Pokémon, the player's name data is removed and stored elsewhere, so the Old Man can be called "Old Man" in their place. This name data happens to be stored in the memory slot where wild Pokémon encounter rates are held. Normally this isn't a problem; the data is overwritten every time the player enters a new area, and their current area has no wild Pokémon to meet. However, flying to Cinnabar Island does not overwrite the data, thus when the player surfs up and down the coast of Cinnabar Island, their name data is called up as wild Pokémon data. This results in a multitude of glitch Pokémon: Pokémon from whatever normal encounter zone you were just in, Pokémon over level 100, and Missingno. Explanation .
As a glitch Pokémon, naturally Missingno. has quite a few oddities. Just encountering it causes the sixth item in the player's back to multiply 128 times. Missingno. and the other glitch Pokémon mentioned here are Bird/Normal-types not Flying/Normal, "Bird" is a dummied-out type with no programmed weaknesses or resistances. There are numerous glitch Pokémon, and the most likely to be encountered aside from Missingno. is "(glitchy block)'M(glitchy block)", or M-Block/'M for short. However, Missingno. is more well-known.
'M is exclusive to Pokémon Red, Green, and Blue. When it's traded to Yellow, it becomes a 3TrainerPoké ₽.
- Ascended Glitch: While Missingno. and 'M have never appeared beyond Gen 1, some later Pokémon reference them.
- Porygon-Z is a glitchy version of Porygon2 created by illegal third-party software being added to its coding, and it looks and behaves in odd ways.
- Deoxys and Giratina are Eldritch Abominations that can change their form, and Deoxys has wildly erratic stats. In addition,Deoxys mutated from a virus (granted a biological one rather than a computer virus) and was officially added to the series in the remakes of Red and Green Versions which Missingno. originated from.
- The Ultra Beasts look like strange, eldritch creatures unlike any other Pokémon, with abilities as strange as their appearances, and they're encountered in a world beyond the normal Pokémon world.
- Beyond the Impossible: To this day, Missingno. is the only Pokémon in the series that can know the same move twice, having Water Gun in two different move slots when encountered.
- Breakout Character: While hardly the only glitch Pokémon, Missingno. is certainly the most well-known. It gets specifically acknowledged by Nintendo's trouble-shooting guide for Red and Blue, and has artwork of all its forms made by a franchise artist; while not exactly official art, that's pretty impressive for something that was never meant to exist in the first place.
- Broke Your Arm Punching Out Cthulhu: If you manage to capture a glitch Pokémon, there's a good chance that your game will glitch out in such a way as to make it unplayable. Missingno. itself is harmless, though, at least in Pokémon Red and Blue. Its cousin 'M is more dangerous, but can be safely handled if care is taken. A general rule of thumb is, the harder it is to encounter, the more likely it is to cause damagenote .
- Chuck Cunningham Syndrome: It only appears in the Generation I games. Justified due to it being a glitch and not a real Pokémon.
- Confusion Fu: It has a bizarre movepool, able to learn Ice Beam, Blizzard, Thunder Wave, Earthquake, Sky Attack, Psychic, Submission, and Bubblebeam. Note that to this day, there is no existing Pokémon other than Mew capable of learning all these attacks.
- Dem Bones: Two of Missingno.'s forms take the front sprites of the Kabutops and Aerodactyl fossils from the Pewter City Museum.
- Department of Redundancy Department: When first caught, Missingno. and 'M know Sky Attack, Water Gun, and Water Gun.
- Did You Just Punch Out Cthulhu?: Missingno. and 'M, strong as they are, have very low defense. Lovecraftian as they are, they aren't that hard to beat.
- Ditto Fighter: The Missingnos. that use the Ghost and Fossil front sprites don't have base stats of their own instead, when their stats are calculated (when captured, leveling up, using the Box Trick, or when being sent out by an opposing trainer), they use the base stats of the last Pokémon that was sent into the battle.
- Dummied Out:
- Its "Bird" type, which is actually a legitimate, unused type, albeit one with absolutely zero weaknesses or resistances. Interestingly, a lot of NPCs refer to Flying as "Bird", which is even kept in the remakes.
- Game designer Shigeki Morimoto once stated that the first generation was supposed to have 190 Pokémon. 39 copies of Missingno. can be found in the index numbers between real Pokémon, totaling 190. True enough, their cries, Pokédex and evolution data, and names are all fully formatted. It turns out that the 39 Missingno. are indeed the remnants of a handful of Pokémon who were left on the cutting room floor.
- Easter Egg: Missingno. returns in the Generation IV games as the blank placeholder tile, which has Missingno's Japanese name written on it in kanji.
- Eldritch Abomination: Its existence is a defiance of the game's internal logic and causes chaos in the world (it exists due to a glitch and can cause more glitches by appearing), it has otherworldly powers and abilities no other Pokémon has (a Dummied Out Typing, knowing two of the same move, and having move combinations no other Pokémon of the time could have), and its physical appearance is incomprehensible and shifting (jumbled mash of pixels, appears as different sprites depending on variables). Additionally, for some reason, the game saves when you encounter Missingno, so just the sight of it glitches up the game.
- Game-Breaking Bug: Despite its several side effects, Missingno. and 'M are mostly harmless. However:
- In Red and Blue, encountering them overwrites the Hall of Fame with glitch datanote and saving the game.
- Depositing a Level 0 'M can make Bill's PC inaccessible, freezing the game if you try to withdraw Pokémon.
- As useful as giving 128 copies of your sixth item in the inventory can be, key items can also be duplicated, making getting rid them extremely time-consuming.
- In Yellow, Missingno.'s front sprite will almost always crash or freeze the game. If you somehow manage to avoid either, it's possible you'll end up in a glitchy overworld with several copies of Red walking around. This does not happen with the Aerodactyl and Kabutops fossil Missingnos, as their sprites are valid.
- 3TrainerPoké ₽ has a Super Glitch as a starting move, making it very prone to corrupting the game when the move's name is seen.
- Even 20 years after its only appearance, Missingno. manages to cause problems in Pokémon Bank. When using the Poké Transporter on a Generation I Virtual Console game, if there's a Missingno. in a box, it will not be visible, but will rename all other Pokémon with the name of the Pokémon that was immediately before them in that box. For example, if there's a Missingno., a Caterpie, a Rattata, and a Pidgey in the same box, you'd see a Caterpie called MISSINGNO-note , a Rattata called CATERPIE, and a Pidgey called RATTATA.
- Glass Cannon: The most common variation of Missingno. has 136 attacknote , with 33/0/6 defenses. Sadly, it lacks the attacks (only the powerful, but unwieldy Sky Attack, unless you use TMs on it) and speed (29) to abuse it.
- Glitch Entity: As the description above states, the game manufactures these Pokémon because you forced it to interpret your character name as wild encounter rates luckily, in most cases, they're not unstable enough to crash the game.
- Go Mad from the Revelation: A popular explanation in fan works for what happens to your player character if the cartridge becomes unplayable due to the above-mentioned Game-Breaking Bug. Your puny human mind snaps like a twig upon seeing the glitchy mess that is MISSINGNO.
- Hybrid Monster: 'M is one of Missingno.
- Making a Splash: 'M knows Water Gun twice. Note this isn't supposed to be possible; a Pokémon cannot learn the same move twice no matter how hard you bend the rules.
- Master of None: In Yellow, Missingno. has a very high HP stat, but its other base stats are below 25.
- Meaningful Name:
- Missingno. = "Missing Number," as in a Pokémon the Pokédex doesn't recognize.
- Zig-Zagged with Ghost Missingno., which has a completely different name in the Japanese versions, said name being "Ghost". It would be fitting for the fact it uses the literal ghost sprite... if it weren't for the fact it's not the name the unrevealed ghosts in the Pokémon Tower use ("Yürei").
- Mighty Glacier: 3TrainerPoké ₽ has extremely high Attack, Defense, and Special, but terrible Speed (and HP, but not enough to counteract its defenses).
- Monster Progenitor: In a sense. After performing the necessary steps to get Missingno. to appear, it's possible you may encounter other things such as 'M (which is not as benevolent of a glitch as Missingno and should be avoided), Pokémon that break the level cap of 100 (they regress back to 100 after gaining a single experience point, not that this applies in link battles), a wild Professor Oak, and other such insanities.
- My Hero, Zero: Both Missingno. and 'M have a Pokédex number of #000. 'M takes it a step further by having an index number of 00.
- Mythology Gag: In the Generation IV games, there's a default sprite whenever a sprite or tile cannot be loaded. That sprite reads Missingno.'s Japanese name, written in kanji.
- No Biological Sex: Or more like "Gender Unknown", as genders were not yet a game mechanic in the Generation I games.
- Non-Elemental: Half Normal-type. In Red and Blue it's a Dummied Out type, in Yellow it's a glitch type as well.
- Not So Similar:
- 'M bears a strong superficial similarity to Missingno. as both use Pokédex Number #000, and can cause the effects (Unreversible Hall of Fame corruption and item duplication) related to said number, but it's only a coincidence. 'M does things Missingno. cannot, such as battling even after it's caught (and if you catch it again, you get a Ditto) and a level 0 'M will freeze the game if withdrawn from a PC. 'M can evolve into Kangaskhan unlike Missingno., and it cannot be found through the extended Mew glitch, displaying an empty text box instead.
- This particular 'M (Index 00) is also very different from the other two that can be found 'M (Index FE) is a Slowpoke hybrid glitch Pokémon with no interesting qualities. 'M (FF) is one of the most dangerous glitch Pokémon in the game (see it and Q ◣'s entry below).
- The Missingnos. that use the Ghost and Fossil front sprites don't corrupt the Hall of Fame, and they are as safe in Yellow as in Red and Blue (as what causes Missingno. crashing the former is its front sprite). They are also Ditto Fighters as seen above.
- Our Ghosts Are Different: One of Missingno.'s forms takes the front sprite of the unidentified ghosts from the Pokémon Tower, although in the Japanese versions it is actually not labeled as a Missingno. variation.
- Overly Long Name: 3TrainerPoké ₽'s covers part of its front sprite thanks to its length and the spaces at its beginning. It gets worse in certain localizations.
- Socialization Bonus: Since 3TrainerPoké ₽ cannot be obtained through the extended Mew glitch (this also applies to 'M) and the Old Man Glitch cannot be done in Yellow, there are only three ways of getting one: String corruptionnote , the Remaining HP Glitch (Requires a Q ◣), or trading an 'M from Red, Green, and Blue.
- Spell My Name with an "S": In Japanese Yellow, 3TrainerPoké ₽'s species name changes depending on the screen it's being seen, but unlike most glitch Pokémon, the altered characters include readable ones.
- Unit Confusion: Missingno. is more than three meters tall and weighs over one and a half tons in Red and Blue. This is because its height and weight were never translated from its Red and Green measures (which is a more reasonable 1 meter and 10 kilograms).
- The Unpronounceable:
- The reason 'M is often called this way by players is because the rest of its species name is composed of glitch characters. More specifically, map tiles. Averted in the Japanese versions.
- Among glitch Pokémon, Missingno. is notable for being the only one whose species name averts this trope, being fully formatted (and pronounceable) in every language. This is one of the hints that Missingno. is actually space left by Dummied Out Pokémon.
- You Cannot Grasp the True Form: Missingno.'s appearance, in the line of all glitch Pokémon that don't use valid sprite dimensions. Its awkward shape (and glitching of Hall of Fame data) happens because the game has no idea how to decompress its sprite. This means Missingno.'s real looks are still unknown the game tries to comprehend it, but it cannot, ending up with its signature L-block shape.
- Your Size May Vary: Depending on whether it shows up in an international or Japanese game, Missingno. will be either 10 feet and 3507 lbs or 3.3 ft (1m) and 22.1 lbs (10 kg), respectively.
Having the index number FF, this variation of 'M and Q ◣ are the most special of glitch Pokémon. At first sight, 'M seems to be a mere hybrid (same color palette, starting moves, Pokédex number, and base stats) of Charizard, as well as having the same sprite (earning its Fan Nickname), while Q ◣ is a hybrid of Starmie, though it does not have the same sprite. However, Charizard 'M and Q ◣ are the closest things to a Reality Warper in the first generation, as their index number is the same as the game uses internally for the CANCEL button.
When they are in the party, any Pokémon placed below them will be treated as non-existent by NPCs, not allowing them (as well as Charizard 'M/Q ◣) to be healed at a Pokémon center, the player's home, or when losing a battle, and can only be healed by items.
During a battle, Charizard 'M has a chance to turn your Pokémon into other Charizard 'M. If battling a Q ◣, the ZZAZZ glitch will be activated, and will freeze the game if the player tries to open the party screen. Q ◣ itself appears as frozen and with an enormous amount of HP (noticeable through the broken HP bar).
When Charizard 'M or Q ◣ is deposited in a box in Bill's PC, it can be used to change the species of the Pokémon deposited after it, while keeping the moves they knew.
Charizard 'M is exclusive to Pokémon Green, Red, and Blue. If traded to Pokémon Yellow, it becomes a Q ◣, and vice-versa.
- Animalistic Abomination: Charizard 'M looks like a gigantic Charizard, but it's much, much more different inside.
- Eldritch Abomination: The biggest examples in the series. Moreso Q ◣ than Charizard 'M, as it uses a glitch sprite instead of the Pokémon it's a hybrid of, and can learn the Super Glitch move at an early level, unlike Charizard 'M learning one at level 204. When a 4 4 Hy evolves into Q ◣, the game gets even more confused and will claim it evolves into TM55 (which does not exist) and will nickname it as such.
- Game-Breaking Bug: Q ◣ triggers the dreaded ZZAZZ glitch, which breaks the game beyond redemption. Inverted with Charizard 'M, an otherwise safe and useful glitch Pokémon that is seen as a consequence of said glitch.
- Giant Flyer: Charizard 'M is about four times bigger and heavier than Charizard. This makes Charizard 'M even bigger than Yveltal.
- Hybrid Monster:
- Charizard 'M is one of Charizard, and Q ◣ is one of Starmie.
- The Pokémon merge glitch can produce Pokémon with moves they don't learn naturally, provided by a Pokémon of another species, which is erased as a result. The remaining HP glitch also produces a hybrid Pokémon.
- Humanoid Abomination: Not Charizard 'M or Q ◣, but the trainer that uses them after the ZZAZZ glitch is activated. It looks just like Rednote , but it's just another corruption.
- Mix-and-Match Critters: One of their most (in)famous uses is exploiting their glitchy nature to create these. The two can be used to perform a glitch that combines two Pokémon into one "hybrid" Pokémon that has the sprite, typing, species, and learnset of one Pokémon, and the stats, moveset, and palette of another.
- No Fair Cheating: Unintentional, but very effective. If you try to use cheat codes to spawn them as wild Pokémon, you find a glitch trainer instead and the ZZAZZ glitch will be activated, corrupting your game.
- Not So Similar: Even though Charizard 'M is one of the three 'M variations of Red and Blue, it's most unlike the other two.
- Reality Warper: They can manipulate a surprising amount of data, as well as hiding Pokémon from NPCs. For example, the remaining HP glitch (changes the species of a Pokémon to the one with an index number equal to its remaining HP) is only possible with Charizard 'M/Q ◣'s intervention.
- Socialization Bonus:
- Both technically count as this trope as the game thinks they are traded Pokémon their trainer ID and original trainer names are never the same as the player's. As a result, they cannot be nicknamed either.
- Since no glitch Pokémon evolve into Charizard 'M (unlike Q ◣), the only way to obtain one without arbitrary code execution, string corruptions (Cooltrainer or Super Glitch), or the fossil conversion glitch (or the remaining HP glitch, but it requires another Charizard 'M to pull it off) is by receiving a Q ◣ through trade. Q ◣ can be evolved from a 4 4 Hy at level 6, and since said glitch Pokémon can appear through the Ditto glitch, it's easy to evolve.
- Unperson: Downplayed. The Pokémon below Charizard 'M/Q ◣'s position (itself included) in the party are treated as if they don't exist by NPCs (the only way to heal any of the aforementioned ones is through items). Once they are placed above it, they become visible to NPCs again.
- The Unpronounceable: Just like most glitch Pokémon, 'M and Q ◣ are called this way because the rest of their names are composed of map tiles. Averted in the Japanese versions in Charizard 'M's case.
- The Virus: Charizard 'M can turn your Pokémon into other Charizard 'M during battle.
A popular glitch Pokémon, it's fairly harmless (at least as harmless as they come) and is a result from the fourth method of the Mew glitch. It's notable for its cry, which changes on cries of other Pokémon having played out and its cry potentially going on for minutes on end and crashing the game. Being a hybrid of Gengar, it can learn all of the same TM moves as it.
It's notable for being the heaviest of the Generation I Pokémon that can be obtained without using a cheating device, weighing in at 6,099 lbs, as well as one of the tallest, standing at over 80' 3"/24 meters tall (which is almost as tall as the Pokémon Tower in Lavender Town).
- Action Bomb: It can learn both Selfdestruct and Explosion, which fits since it's a hybrid of a Gengar.
- Animals Not to Scale: It's a hybrid of Gengar, but it's absolutely massive.
- Acrofatic: It weighs almost 6,100 pounds, but its Speed stat is its second-highest Base stat at 110.
- Brown Note: Its cry, of course, but also its Pokédex entry.
- Black Speech: Its Pokédex entry is nothing but gibberish, besides the words "ROCKET" and "Enemy h POKé."
- Creepy Good: It's harmless to the player's game, but considering what it looks like to the player (and is almost as tall as a 7-story building), it's worth putting it here.
- Dark Is Not Evil: It's a Ghost-type glitch Pokémon (specifically, a hybrid of Gengar), but it's one of the more benign glitch Pokémon even though its cry can get so long it pretty much crashes the game without actually crashing it.
- Eldritch Abomination: Being a Glitch Entity, it's expected.
- Glitch Entity: It isn't as popular as Missingno./'M or Charizard 'M, though.
- Harsh Vocals: If you can call its cry "vocals."
- Hell Is That Noise: Its cry.
- Overly Long Gag: Its cry, which changes based on what Pokémon the trainer last saw before bringing it out. It's a good idea to save before going into anywhere where a battle may occur, since its cry can go on for minutes on end, or even freeze the game on rare occasions.
- Our Ghosts Are Different: VERY DIFFERENT.
- Secret Art: Night Shade, which fits since it's a hybrid of Gengar.
- Shock and Awe: It can learn both Thunderbolt and Thunder.
- Useless Useful Spell: It's capable of learning Conversion, the Porygon line's signature move, and it works just as well for it, if not better.
- Glass Cannon: While 44's attack and defense stats are reasonably respectable (116 and 108, respectively), it only has 14 HP and its speed is at 0, thus meaning that the opponent will always hit first, and probably take 4 4 out... assuming the game doesn't break first.
- Hell Is That Noise: As demonstrated in this video, 4 4 has a truly horrifying voice: It imitates Pikachu's cries, but follows up with a barrage of corrupted digital screaming.
- Interface Screw: 4 4 is quite difficult to use in battle, as its back sprite is a glitch screen that covers the whole interface in black.
- Death from Above: It can learn Fly and do pretty good damage with it.
- Master of All: It really bears repeating that this thing's lowest stat is a base 128 Speed, and all of its other stats are fairly even, making it monstrously powerful on all fronts. Its relatively balanced stat spread is also something of an oddity among glitch Pokémon, which tend to have base stats that are all over the place.
- Non-Elemental: While it does have a secondary glitch type, that type (like all glitch types) has no weaknesses or resistances, making it functionally a pure Normal-type Pokémon.
- Purple Is Powerful: And HOW. This Glitch Pokémon is one of the most powerful creatures in the entire series, and is even stronger than Mega Rayquaza! Although... (SPOILERS FOR THE GEN VIII GAMES) This thing is nearly unstoppable especially if you raise it to Level 100. God help your enemies.
- Version-Exclusive Content: Outside of Yellow it becomes PokéWTrainer, a glitch Pokémon that somehow has even higher stats... but also crashes the game if you see its front sprite.
A corruption of Pokémon data that appears from Gen III game onwards, this egg-looking abomination may appear if cheating devices are used in reckless ways.
- Animalistic Abomination: It looks the same as an ordinary Pokémon egg, but is far from one in nature.
- The Assimilator: In Emerald, when warp cheat codes are used to steal from the Battle Factory, an invisible Bad Egg appears in the 19th slot of the 1st box in the PC Storage. If a Pokémon is already in that slot, then it'll become corrupted and merges into a proper Bad Egg.
- Clingy Macguffin: Once you get landed with a Bad Egg, good luck getting rid of it. They can't be released due to being Eggs, forcibly hatching one crashes the game, and in the earlier generations they might even come with Seals, preventing them from being put in the PC.
- Early Installment Weirdness: A similar glitch Pokémon exists in Generation II simply called "Egg", or "Glitch Egg" by fans.
- Game-Breaking Bug: Bad Eggs from certain sources tend to freeze the game when their information is viewed, and forcing one to hatch will do the same. Heck, just seeing a Bad Egg can sometimes cause a freeze.
- Glitch Entity: Bad Egg is not an actual Pokémon, but rather the result of the game getting a bad checksum, indicating that there's something wrong with game data (such as having a Pokémon with more than 510 EVs or attempting to force an encounter with an ID number that doesn't correspond to an actual Pokémon). Which, in these games, is usually the handiwork of a cheating player.
- My Name Is ???: Or rather, the name of its "original trainer" is ?????, as their id number.
- No Fair Cheating: It will only appear when you use cheating devices.
