Appendix:Fan terminology

(Redirected from HM mule)

The Pokémon metagame has a wide range of fanmade terminology for various aspects of the games. These are colloquial terms originating from unofficial sources, and are not found within the games themselves. However, some terms originally coined by the fandom have been used officially, such as Eeveelution and Shiny; these terms are not listed here.

Pokémon terms


A set of two version-exclusive Pokémon and their evolutionary families, each found in a different game, sometimes referred to as parallels. These counterparts may be identified by commonalities such as typing, base stats, evolution method, and the locations where these Pokémon may be found. The term may also be used to describe Pokémon that are more common in one game version than another, as well as Pokémon that are only exclusive in a single pair of games.

Convergent form/Convergent Pokémon

Main article: Ecologically similar Pokémon

Fan terms for Pokémon which resemble another species without being related biologically. These refer to the Wiglett, Toedscool, and Poltchageist lines, whose designs are based on the Diglett, Tentacool, and Sinistea lines, respectively. The term is derived from the real-world phenomenon of convergent evolution. Alternatively, some fans call them "regional fakes" as this concept resembles previously introduced regional forms.

Early-route Pokémon

A Pokémon found in the first few routes of the game. These can be divided into:

Electric rodents

Main article: Electric rodents
Artwork of the pre-Generation IX electric rodents and Mimikyu

A group of Electric-type Pokémon based on rodents, consisting of Pikachu, Raichu (sometimes omitted), Pichu (sometimes omitted), Plusle, Minun, Pachirisu, Emolga, Dedenne, Togedemaru, Morpeko, Pawmi, Pawmo, and Pawmot. Design-wise, all of them have electric sacs on their cheeks. This group is also referred to as the Pikachu family, Pikachu clones, or Pikaclones. An equivalent term used within the Japanese fandom is 電気袋組(でんきぶくろぐみ) Electric Pouch Group.

Elemental monkeys

Main article: Elemental monkeys

Pansage, Pansear, Panpour, Simisage, Simisear, and Simipour. The name is derived from the fact that all of them are based on monkeys and have different types (Grass, Fire, and Water respectively). They also share resemblance to first partner Pokémon.

Game mascot

Main article: Game mascot

A Pokémon that appears on the boxart of one of the Pokémon games in the core series. If it is a Legendary Pokémon, it is also referred to as a box art legendary.


Main article: Hitmons

Hitmonlee, Hitmonchan, Hitmontop, and sometimes Tyrogue. They are also referred to as the Tyrogue squadron.[1]


Main article: Fossil → Generation VIII

(Japanese: カセキメラ Kasekimera) is used within the Japanese fandom to collectively refer to Fossil Pokémon introduced in Generation VIII: Dracozolt, Arctozolt, Dracovish, and Arctovish. The term is derived from the Japanese word 化石 kaseki (fossil) and the English word chimera.

Legendary group

Main article: Groups of Legendary and Mythical Pokémon

A group of Legendary Pokémon. The most common groupings include Legendary duo and Legendary trio.

Legendary duo

A group of two Legendary or Mythical Pokémon that share some association.

Includes Mew, Celebi, Jirachi, Manaphy, Shaymin, and Victini. Sometimes referred to as Mythical fairies, although that term is also used to describe the lake guardians.

Novelty Pokémon

Also known as gimmick Pokémon, a Pokémon that possesses a unique trait, usually in battle. Pokémon most often to be considered novelty are: Magikarp, Ditto, Eevee, Porygon, Unown, Wobbuffet, Shuckle, Smeargle, Wurmple, Slaking, Shedinja, Plusle with Minun, Spinda, Castform, Kecleon, Deoxys, Burmy, Cherrim, Rampardos, Gastrodon, Rotom, Arceus, Darmanitan, Zoroark, Sawsbuck, Accelgor with Escavalier, Keldeo, Meloetta, Genesect, Ash-Greninja, Vivillon, Aegislash, Zygarde, Oricorio, Wishiwashi, Pyukumuku, Minior, Komala, Mimikyu, Necrozma, Cramorant, Toxtricity, Eiscue, Morpeko, Palafin, and Dondozo with Tatsugiri.

Sub-Legendary Pokémon

Legendary Pokémon that are permitted in battle facilities and usually permitted in official tournaments. These Pokémon (besides Generation VI) include:

A list in the data since Pokémon Sun and Moon, named "sublegend" in the game code, grouped the Ultra Beasts with all of the sub-Legendary Pokémon, despite them not being Legendary Pokémon. This grouping continued until Pokémon Scarlet and Violet, in which Ultra Beasts are no longer grouped under this "sublegend" list.

Legendary Pokémon that are not sub-Legendary Pokémon are officially known as Special Pokémon.

Type triangle

A trio of types where one beats another and loses to another, such as Water-Grass-Fire or Dark-Fighting-Psychic, notably used for first partner Pokémon. Both the Dragon and Ghost types can create type triangles by themselves only. Normal-type is the only type that isn't super effective against any type, but weak against the Fighting type. All single type triangles go as follows:

Type 1 Type 2 Type 3
Perfectly balanced
½×   ½×   ½×  
½×   ½×   ½×  
½×   ½×   ½×  
½×   ½×   ½×  
Unilaterally balanced

Fan terms


A term referring to the controversy surrounding Game Freak's announcement that some Pokémon would not be usable in Pokémon Sword and Shield. Derives from a portmanteau of "Pokédex" and "Brexit", a debate between UK citizens concerning whether the UK (which is the basis of Galar, the setting of Sword and Shield) should leave the European Union.


A pejorative term used to describe fans who dislike elements of the Pokémon franchise released after Generation I (and, to a lesser extent, Generation II). A corruption of "Generation One". Originated from the Transformers fandom's term of "Geewun", where some fans have a similar stance on their franchise. However, fanon terms relating to other generations in the franchise (such as Generations III or IV) are less often used.


A term used to refer to any female character in the Pokémon franchise. Derives from a portmanteau of "Pokémon" and "girl".

Game terms


The general concept of a boss in video games may refer to special, strong opponents who must be defeated to obtain an important reward or advance past a particular point in the game. In the Pokémon games, there are various figures who may fit this description:

Collection terms

Living Pokédex

Main article: Living Pokédex

Having a Pokémon of every species (available in that game) in the Pokémon Storage System at the same time.


A Pokémon or item obtained without cheating or intentional glitch use. Typically this refers to a Pokémon or item obtained through normal gameplay, without any third party modifications to the game's ROM or RAM. Pokémon obtained via RNG Abuse, or via bugs that the player would run into naturally during normal gameplay, (Gen 3's Roamer IV bug for example), are still typically considered legitimate as the game would generate those Pokémon within the bounds of what was possible to obtain naturally, in an unmodified instance of the game.

  • Note that Legitimate does not inherently mean Legal, it is possible to encounter Pokémon during normal gameplay that have otherwise impossible attributes, and the The Pokémon Company would consider unauthorized.
    • 1★ Wild Area News Drilbur with Hydro Pump is an example of a Pokémon that was legitimately obtainable but considered Illegal, as it was programmed with a game move error. The game does not permit its use online nor official tournaments, and several hours after the mistake was discovered GameFreak had fixed the erroneous Wild Area News data to replace Hydro Pump with the correct move, Scratch.
    • These situations are typically handled case-by-case. As a counter example, the 5★ Tera Raid Battle Female Indeedee with the error move Trick Room is not blocked from online use, and in early December 2022 even saw prior restrictions removed, permitting raids with the erroneous move to be hosted online to other players, and later patched the game to allow Female Indeedee to learn Trick Room via TM. In a situation like this, it could be argued the developers consider this error to be both Legal and Legitimate, despite the similar circumstances to the aforementioned Drilbur with Hydro Pump.
  • Additionally, the state of the savefile itself is generally not taken into account when determining the legitimacy of an individual Pokémon. Even if the savefile is in an unnatural state via glitches, cheats, save editing, etc., if the generation/encounter conditions of a Pokémon are unaffected, a savefile in an unnatural state can still produce Legal and Legitimate Pokémon.
    • As an example, using a glitch that warps the player to an area early, but does not alter the encounter conditions of Pokémon found in that area, would generate Pokémon in an identical manner to a player who arrived in that area under normal gameplay conditions.

A Pokémon or item obtained via cheating or intentional glitch use. Typically this refers to a Pokémon or item generated via any third party modifications to the game's ROM or RAM, or with the use of intentional glitches to drastically alter the game into a state where it produces Pokémon or items in a way it would never be able to during the course of normal gameplay.

  • This term may also be used to refer to event Pokémon generated outside of their typical distribution periods or methods via glitches, Arbitrary code execution, Wonder Card injection, or other exploits such as the DNS Exploit.
    • Contrary to the above, several event Pokémon are programmed as in-game static encounters or gifts accessible via activating an in-game event or event-exclusive location (such as Birth Island's Deoxys or Faraway Island's Mew), rather than generated directly by a Wonder Card.
      It could be argued that if an encounter is accessed via warp glitches, (on a game version/language the encounter was legitimately obtainable in, i.e. Faraway Island's Mew is only legitimately accessible on Japanese language copies of Pokémon Emerald, accessing it on an English copy of Emerald would result in an Illegal Mew), that since the encounter itself is unmodified and available in the base game, the Pokémon itself could be considered both Legal and/or Legitimate even if the savefile itself is in an unnatural state.
  • Illegitimate Pokémon and items are not limited to just those produced via cheating using third party tools, as Pokémon or items generated directly via Cloning glitches or Arbitrary code execution would still fall into this category, even if the result would be considered Legal.

A Pokémon or item in a state that is possible to achieve through normal gameplay. This means that regardless of what method was used to obtain it, one could obtain this Pokémon in its current state without cheating or intentional glitch use.

  • Note that this is not inherently the same as Legitimate. While most Legitimate Pokémon are also Legal, this term only refers to the current state of the Pokémon and whether it could be theoretically obtained in that state through normal gameplay. A Pokémon may still be Legal even if it was obtained through the use of third party modifications, cheats, glitches, etc.

A Pokémon or item in a state that is typically impossible to achieve through normal gameplay, and/or is disallowed by The Pokémon Company. This means that regardless of what method was used to obtain it, this Pokémon has at least one value that could only be obtained via cheating, intentional glitch use, or via an oversight by the developers of the game that permitted it to be obtained.

  • Note that a Pokémon can still be illegal even if permitted to be used online, having not been detected by the server's anti-cheat detection, as the term refers to the Pokémon itself being in an unobtainable state, not necessarily whether it is detected by the game's anti-cheat.
  • It is also possible for illegal Pokémon or items to be obtained, or even generated by players who are not cheating, having only interacted with the game via legitimate means, as a result of interference by other cheating players.
    • One such instance would be breeding using a parent Pokémon that has an impossible combination of Poké Ball and species, obtained via trade from a cheating player. A Skeledirge in a Beast Ball for example, is currently an impossible combination due to Skeledirge being unavailable to be captured in the wild. If bred, an illegal Fuecoco Egg would be produced, inheriting the Beast Ball from the illegal parent.
    • Another instance would be a player joining a hacked Max Raid via Y-Comm, (prior to Sword and Shield v1.2.1), and then catching the resulting illegal Pokémon, or receiving unobtainable item as a reward for defeating it. As a result, Pokémon and items that were impossible to receive via trade due to anti-cheat detection were made possible to obtain on an unmodified savefile, as the Pokémon and items are generated client-side by the non-cheating participant's game.


A Pokémon that is in the same state as it was obtained in. Specifically, it has gained no experience, levels, EVs, or Ribbons, had none of its moves changed or reordered, and has not evolved, gained Pokérus, or had its pre-existing Pokérus become inactive. Commonly used to refer to event Pokémon and in-game gift Pokémon.


A term used by collectors to describe catching Pokémon with a specific type of Poké Ball. Often this involves a desire to have the Ball's color scheme, thematic properties, or release animation align with the Pokémon it contains, as well as unique or unlikely combinations being valued, such as Pokémon obtained in Apriballs, or non-Ultra Beast species being obtained in Beast Balls, (despite the drastically lower catch rate when used on other species).

Likely a portmanteau of "Ball" and either "Elitism" or "Autism"; sometimes used as a pejorative term in reference to one's obsession with obtaining a given Pokémon in a specific type of Ball, or devaluing Pokémon deemed to be in a "non-matching" type of Ball.

On April 24, 2021, the merchandise line "BALL FREAK", which prominently featured the concept of matching Pokémon and Poké Balls of similar style/coloration, released on the Japanese Pokémon Center website,[2] however this terminology hasn't appeared in any other media. It's currently unclear if The Pokémon Company considers "ball freak" an official term for the concept, or if it was only intended for use as a title for the specific merchandise line.

Game acronyms

Most of the Pokémon games come in pairs and are often followed by enhanced versions, hence Pokémon fans call them collectively with the first letters of their names.

Gameplay terms

6IV or 6V

Refers to either a Pokémon with individual values of 31 for all 6 stats, or a Pokémon with all 6 stats set to "competitively viable" values. This is also commonly referred to as "perfect IVs".

  • As an example, some competitive strategies require a Pokémon to have an intentionally lower stat, such as an IV of 0 for Attack, or Speed. Strategies using Trick Room or Gyro Ball may benefit from a Pokémon having a lower Speed stat than the opponent, therefore a Pokémon with IVs of 31 in every other stat, but with a Speed IV of 0, may still sometimes be referred to as 6IV or "perfect".

The term "5IV" or "5V" (a Pokémon with IVs of 31 in only five stats) is also commonly used due to the breeding effect of Destiny Knot introduced in Generation VI, allowing for the value of 5 random IVs of a bred Pokémon to be inherited from the parents if either parent holds the Destiny Knot.


A method used to repeatedly encounter the same Pokémon via a feature such as Poké Radar and DexNav, which lines up the chance of getting a desired Pokémon. Chaining with the Poke Radar is often tried for the purposes of getting a Shiny Pokémon of a specific species.


Main article: Cheating

The use of any device unauthorized by The Pokémon Company to modify a Pokémon game. Being found to have cheated in any way, or having a Pokémon that was obtained by cheating on another game will result in immediate disqualification from any official tournament, and disqualification from all future official tournaments.

EV training

Intentionally battling Pokémon for the EVs they give out in order to ensure EVs are distributed in a specific way or capped.

Focus Miss/Stone Miss/Will-O-Miss

Derogatory terms for Focus Blast, Stone Edge, and Will-O-Wisp, referring to the moves' mediocre accuracy.

Gear Station or Centrico Plaza trick

Securing the D-pad or analog stick in one direction so that the player continuously walks around the circular Gear Station or Centrico Plaza, resulting in an effortless refilling of Hidden Grottoes, increase in friendship, hatching of Eggs, and accumulation of Poké Miles.


Training a Pokémon to a certain level through repetitive battling.


A Pokémon with the Ability Flame Body, Magma Armor, or Steam Engine such as Fletchinder, Slugma, and Rolycoly in the party, mainly used for hatching Eggs faster.

HM mule

A Bibarel that knows four field moves

A term used within parts of the fandom to refer to a Pokémon in a Trainer's party that is used for navigational support through the use of field moves—generally those taught by Hidden Machines. HM mules will typically have three or four move slots occupied with field moves, allowing smooth passage through caves, across oceans, or past other obstacles at the expense of their battling capabilities.

With the retirement of HMs and field moves from Generation VII onward, HM mules are not necessary in those games. In Generation VII, the functions of HMs are replaced by Poké RidesSMUSUM and Secret TechniquesPE. In Pokémon Sword and Shield, the Rotom Bike's Water Mode replaces Surf and the Flying Taxi replaces Fly. In Pokémon Legends: Arceus, various ride Pokémon provide similar functions, allowing the player to traverse through Hisui faster, swim through water, climb steep cliffs, and glide through the air. The Arc Phone's map allows players to warp between locations, replacing Fly. In Pokémon Scarlet and Violet, traversal abilities are gained by the player's KoraidonS/MiraidonV during the Path of Legends storyline, and the Flying Taxi from Sword and Shield returns.

HM mules are often referred to as HM slaves or HM friends. An equivalent term used within the Japanese fandom is 秘伝要員, with 秘伝 being from 秘伝マシン Hidden Machine followed by 要員 personnel.


A Skitty and a Wailord at the Day Care

The fan term HSOWA is an initialism that stands for "Hot Skitty On Wailord Action". It is derived from the fact that Skitty and Wailord can breed in the games despite their massive size difference. It has reached cult status on some message boards. The term originates from GameFAQs.

IV breeding

Intentionally breeding Pokémon to have a specific IV or set of IVs.

Masuda method

Main article: Masuda method

The game mechanic that increases the likelihood of Shiny Pokémon to hatch from Eggs if the parents are from differing real-world geographical locations. Named after Junichi Masuda, who first documented this mechanic in his blog.

Nuzlocke Challenge

Main article: Nuzlocke Challenge

A special challenge playthrough of a Pokémon game in which the player must follow a set of self-enforced rules to make the game more difficult. Most notably, the player can only catch the first Pokémon they encounter on each route, and must release any Pokémon that faints. Named after the comic series of the same name that first proposed the type of playthrough.

Professor Oak Challenge

A time-consuming challenge playthrough of a Pokémon game in which the player must fill up the Pokédex to its limit before taking on each Gym Leader. This challenge was created by user Chamale on Reddit, and popularized by YouTuber 'JohnStone'.

Repel trick

Main article: Appendix:Repel trick

Main article: List of unobtainable Shiny Pokémon

Referring to a Pokémon obtained in a particular game that is prevented from being Shiny.

Spinner trick

Securing the D-pad or analogue stick in a single direction so that the player continuously walks into a spin tile, resulting in an effortless increase in friendship and hatching of Eggs. Often called the "Fuego trick" in Pokémon Diamond, Pearl, and Platinum due to Fuego Ironworks being the optimal location for doing so.


Pokémon with the Ability Synchronize such as Abra and Ralts in the first place in the party, mainly used for obtaining Pokémon with the desired Nature.

Walking Pokémon

Main article: Walking Pokémon

Pokémon that walk alongside their Trainer when they normally would be inside their Poké Balls outside of battle. Also referred to by fans as Pokémon following you.


Main article: Apricorn

Referring to the Poké Balls crafted using Apricorns in Johto, KantoHGSS, or Galar regions, specifically the Heavy, Lure, Friend, Love, Level, Fast, and Moon Balls.

Despite Poké Balls in Pokémon Legends: Arceus also being craftable using Apricorns, this term doesn't refer to Poké Balls from the Hisui region.

Metagame terms

Main article: Appendix:Metagame terminology

Technical terms


Main article: Effort values

Effort values, often shortened to EVs and officially known as base points, are capped permanent stat bonuses gained by defeating Pokémon, using items such as vitamins or wings, or using services such as those in Join Avenue. They ensure trained Pokémon are stronger than newly caught Pokémon.

Main article: Go Power

Awakening values, often shortened to AVs and officially known as Go Power, are used in Pokémon: Let's Go, Pikachu! and Let's Go, Eevee! in place of EVs. AVs are used to increase a Pokémon's stats, but are awarded through the use of Candy and leveling up, rather than by defeating other Pokémon in battles or consuming vitamins.

ELs or GVs
Main article: Effort level

Effort levels, often shortened to ELs, (referred to internally as "Ganbaru values", often shortened to GVs), are a mechanic introduced in Pokémon Legends: Arceus. Effort levels take the place of effort values from previous games. Pokémon gain effort levels through the use of Grit items, but will initially begin with 0-3 ELs in each stat, with the amount being determined by the Pokémon's IVs.


Main article: Individual values

Individual values, often shortened to IVs, are fixed values that can be inherited from the Pokémon's parents. They ensure Pokémon are genetically different.


Main article: Personality value

A shortened version of the term personality value, a hidden value used to determine several properties of a Pokémon, including Shininess. Generation VI onwards, this value is split into two separate values, with the latter being referred to as the Encryption Constant, often shortened to EC.


Pokémon Shiny Value, often shortened to PSV, and Egg Shiny Value, often shortened to ESV, are values derived from a Pokémon or Egg's personality value, designed as an easy way to tell if the Pokémon or Egg will appear as Shiny for a given player, if the value is the same as that player's Trainer Shiny Value, (often shortened to TSV).


Main article: Trainer ID

Trainer ID, often shorted to TID, is the 5 to 6 digit value displayed on the player's Trainer card, League Card, or in-game save menu. The Secret ID, often shortened to SID, is a hidden 4 or 5 digit value used alongside the Trainer ID to determine which Pokémon will appear as Shiny for the player, according to the Pokémon's personality value.


Trainer Shiny Value, often shortened to TSV, is a value derived from the player's Trainer ID and Secret ID, designed as an easy way to tell if a given Egg or Pokémon will be Shiny for the player, if their Egg Shiny Value, (often shortened to ESV), or Pokémon Shiny Value, (often shortened to PSV) is the same value as the player's Trainer Shiny Value.

RNG or RNG Abuse

Main article: Pseudorandom number generation

Refers to the Random Number Generator, or the practice of manipulating it through the use of fan-made software (commonly referred to as RNG Abuse), in order to obtain Shiny Pokémon or Pokémon with specific IVs—both endeavors which would otherwise leave a lot up to chance.
