View source for Groups of Legendary and Mythical Pokémon

{{Unknown name}}
A '''Legendary group''' is a term used to describe a group of closely related {{pkmn2|Legendary}} or [[Mythical Pokémon]]. '''Legendary duo''' and '''Legendary trio''' are terms that have been used to refer to pairs and groups of three Legendary or Mythical Pokémon. The [[sea guardians]], consisting of two Mythical Pokémon, are referred to as a '''Mythical duo'''. Less commonly, '''Legendary quartet''' and '''Legendary quintet''' have been used to refer to groups of four and five, respectively. 

Several Legendary groups also have a close relationship with another Legendary or Mythical Pokémon who may be considered their leader or creator. For Legendary trios, this Pokémon has often been referred to by fans as a '''trio master'''. There are also other Legendary and Mythical Pokémon that are closely associated with a Legendary group, but are not considered a leader or member of that group. Additionally, there are some Legendary Pokémon that are closely related but not officially or commonly recognized to be part of their own distinct group.

Members of Legendary groups often, but not always, share at least one [[type]], [[Ability]], or [[Base stats|base stat]] total.

==Terminology==
===Legendary duo===
From [[Generation VII]] onwards, "'''Legendary duo'''" has been officially used on the [[Pokémon.com]] website.

In particular, this term was used at one point referring to [[Primal Reversion|Primal]] {{p|Groudon}} and {{p|Lunala}} together, in the context of their use in Double Battles:

* ''"Up next we have the winning restricted pairing from the 2019 Pokémon World Championships, Primal Groudon and Lunala. [...] Opponents will be better prepared for this pairing with the knowledge of how the team operates, meaning it’s only going to get more difficult for this '''Legendary duo''' to continue with its recent success."''<ref>[https://www.pokemon.com/us/play-pokemon/internationals/2020/latin-america/vgc-power-rankings Latin America Internationals: Pokémon VGC Power Rankings - Pokémon.com]</ref>

Another example:
* ''"In [[Pokémon Sun and Moon|Pokémon Sun and Pokémon Moon]], the story centered heavily around the [[Legendary Pokémon]] {{p|Solgaleo}} and {{p|Lunala}}. In [[Pokémon Ultra Sun and Ultra Moon|Pokémon Ultra Sun and Pokémon Ultra Moon]], a new story unfolds featuring {{p|Necrozma}} alongside the '''Legendary duo'''."''<ref>[https://press.pokemon.com/en/releases/NEW-DETAILS-ANNOUNCED-FOR-UPCOMING-GAMES-POKEMON-ULTRA-SUN-AND-P-66605 NEW DETAILS ANNOUNCED FOR UPCOMING GAMES POKÉMON ULTRA SUN AND POKÉMON ULTRA MOON!]</ref>

===Legendary trio===
From [[Generation IV]] onwards, "'''Legendary trio'''" (originally as '''legendary trio''' in lowercase) has been officially used on the [[Pokémon.com]] website:

* ''"Catch up with the '''legendary trio''' of {{p|Entei}} (4/132), {{p|Raikou}} (16/132), and {{p|Suicune}} (19/132)!"'' (referring to {{TCG|Diamond & Pearl}}—{{TCG|Secret Wonders}} from the [[Pokémon Trading Card Game]])
* ''"The '''Legendary trio''' of {{p|Raikou}}, {{p|Entei}}, and {{p|Suicune}} are majestic, ferocious, and really hard to catch."'' (referring to the [[Nintendo 3DS]] [[Virtual Console]] version of {{game|Gold and Silver|s}})<ref>[https://www.pokemon.com/us/strategy/ten-cant-miss-activities-in-johto-and-beyond Ten Can’t Miss Activities in Johto and Beyond - Pokémon.com]</ref>
* ''"Each of these battles has a five-minute time limit, so you'll need to be efficient as you take on this '''Legendary trio'''."'' (referring to {{p|Articuno}}, {{p|Zapdos}}, and {{p|Moltres}} in [[Pokémon: Let's Go, Pikachu! and Let's Go, Eevee!]])<ref>[https://www.pokemon.com/us/strategy/postgame-adventures-in-pokemon-lets-go-pikachu-and-pokemon-lets-go-eevee Postgame Adventures in ''Pokémon: Let’s Go, Pikachu!'' and ''Pokémon: Let’s Go, Eevee!'' - Pokémon.com]</ref>

===Other terms===
Some terms have been used by fans but are not known to be officially used: "'''Legendary group'''", "'''Legendary leader'''", "'''Legendary quartet'''", and "'''Legendary quintet'''".

==List of Legendary groups==
===Legendary duos===
[[File:Eon duo anime.png|thumb|250px|The [[eon duo]] in the {{pkmn|anime}}]]
A Legendary duo is a pair of closely related {{pkmn2|Legendary}} and [[Mythical Pokémon]], either representing teamwork or opposition.

In the {{pkmn|games}}, Legendary duos are often found after the {{player}} enters the [[Hall of Fame]] but they usually are not as important to the main storyline as the trios are. Duos or their component parts are featured in several of the {{pkmn|movie}}s as keepers of peace.

Sometimes, pairs of Legendary Pokémon once only presented as duos are revealed to actually be Legendary trios in a subsequent game or games of the same generation. However, even within trios, the dynamic between two of the members is often very close to that of a duo: {{p|Kyogre}} and {{p|Groudon}}, {{p|Dialga}} and {{p|Palkia}}, {{p|Reshiram}} and {{p|Zekrom}}, {{p|Xerneas}} and {{p|Yveltal}}, and {{p|Solgaleo}} and {{p|Lunala}} are all examples of this.

===Legendary trios===
[[File:Tao trio anime.png|thumb|250px|The [[Tao trio]] in the {{pkmn|anime}}]]
A Legendary trio is a term used to describe a group of three closely-related [[Legendary Pokémon]]. Legendary trios can be subdivided into two tiers: normal trios and {{pkmn2|Special}} trios. Sublegendary trios, which are always the first Legendary Pokémon that appear in any [[Pokédex]] order, are allowed into the many [[Battle Tower]]s and other [[Battle facility|battle facilities]]. They are also the only Pokémon with [[base stats|base stat]] totals of {{cat|Pokémon with a base stat total of 580|580}}, besides the [[Swords of Justice]]. Special trios, whose name comes from the fact that all of them are [[Special Pokémon]], are not allowed in the [[Battle Tower]] and are found closer to the end of the Pokédex in the generation of their release.

Before the introduction of new members to some Legendary groups, the [[Forces of Nature]] and [[Legendary giants]] used to be Legendary trios. The [[Swords of Justice]] are also sometimes treated as a trio when {{p|Keldeo}} is excluded.

The term fell into official usage with the {{Shiny}} [[Legendary beasts]]' [[Wonder Card]]s.

===Legendary quartets===
[[File:Guardian deities anime.png|thumb|250px|The [[Guardian deities]] in the {{pkmn|anime}}]]
A Legendary quartet is a term used to describe a group of four closely related [[Legendary Pokémon]]. Legendary quartets are mainly sub-Legendary, Keldeo being the only exception. Legendary quartets are usually the first Legendary Pokémon that appear in any [[Pokédex]] order and are allowed into the many [[Battle Tower]]s and other [[Battle facility|battle facilities]]. The only exception is {{p|Keldeo}} due to being a [[Mythical Pokémon]]. They tend not to have leading story roles and are mainly optional captures.

[[File:Legendary titans anime.png|thumb|250px|The Legendary giants in the {{pkmn|anime}}]]
A Legendary quintet is a term used to describe a group of five closely related [[Legendary Pokémon]]. Legendary quintets are mainly sub-Legendary groups. So far, the only Legendary quintet is a Legendary trio that has received new members several generations after their debut.

==Other relationships==
===Legendary leaders===
[[File:Super-ancient Pokémon.png|thumb|250px|Rayquaza arriving to quell Groudon and Kyogre's fighting]]
Some {{pkmn2|Legendary}} or [[Mythical Pokémon]] are known to oversee one or more Legendary groups. For Legendary trios, this Pokémon has been referred to by fans as a trio master, though some Legendary trios with leaders have since expanded into larger groups.

This Pokémon and its Legendary group may relate in different ways. For example, {{p|Lugia}} is often considered the leader of the [[Legendary birds]]; it is the only one who can quell their fighting when [[Lawrence III]] captures one of them in the second movie, ''[[M02|The Power of One]]''.

Sometimes a particular member of a group oversees the other members, serving as what some fans have called an '''internal master'''. For example, {{p|Rayquaza}} is the leader of the [[super-ancient Pokémon]]; it stopped the other two members' fighting in {{game|Emerald}}. Another example is mentioned in the [[Generation V]] games; {{p|Landorus}} punishes {{p|Thundurus}} and {{p|Tornadus}} for causing storms as a result of their fighting.

In the {{pkmn|games}}, these Pokémon often require that their subordinates be caught before being encountered.

Arceus, known as the Original One, was named Almighty Sinnoh by the Celestica people, before the [[Diamond Clan|Diamond]] and [[Pearl Clan]]s had used the name to refer to Palkia and Dialga instead. Arceus was also shown to be capable of using the Pokémon of Myth's powers at will, manipulating time, space and anti-matter, even including their signature moves, {{m|Roar of Time}}, {{m|Spacial Rend}} and {{m|Shadow Force}}, as seen in its boss fight.

On several occasions, certain regular, {{pkmn2|Legendary}} or [[Mythical Pokémon]] have shared a history or close relationship with a Legendary group, often playing a pivotal role in their stories. However, these Pokémon are not considered official members of the main Legendary group.

This pillager of light had fought against a young kid along with the [[guardian deities]] using [[Z-Power]] and [[Sparkling Stone]]s defeating Necrozma.

When Ogerpon is sent into battle against {{p|Pecharunt}} in the [[Mochi Mayhem]] epilogue, it will give a similar vicious reaction, as Pecharunt is responsible for the Loyal Three's toxic chains, and accompanied them when they stole Ogerpon's masks.
