Legendary Pokemon: Every Legendary and How to Obtain Them
Legendary Pokémon sit at the top of the franchise's hierarchy — rare, narratively significant, and mechanically distinct from anything caught in a standard route encounter. This page covers how Legendaries are defined, how the capture and encounter systems work across the main series, the most common acquisition scenarios players face, and the practical distinctions that separate one type of Legendary situation from another. Whether tracking down Roaming Legendaries in older games or chain-resetting for a specific Nature, the mechanics reward understanding the system first.
Definition and scope
A Legendary Pokémon is a category designation used by Game Freak and The Pokémon Company to identify Pokémon that are, by design, unique or extremely rare within their game's world. The formal category appears in official Pokédex entries, promotional materials, and the games' own UI in titles like Pokémon Legends: Arceus. As of the Scarlet and Violet generation (Generation IX), the roster of recognized Legendaries sits at over 60 distinct species, not counting Mythicals — a closely related but mechanically separate category covered in detail on the Mythical Pokémon guide.
The distinctions matter. Legendaries are obtainable through standard in-game play — no event codes, no limited distribution windows. Mythicals (Mew, Celebi, Jirachi, Marshadow, and others) historically required external distribution events, making them structurally different even when their base stats are comparable.
Legendaries also differ from pseudo-legendary Pokémon, a fan-coined term for three-stage species with a base stat total of exactly 600 — Dragonite, Tyranitar, Metagross, and their successors. Pseudo-legendaries breed, evolve through standard methods, and have no in-game unique status. True Legendaries are typically uncatchable duplicates: once obtained, the encounter closes.
How it works
The encounter structure for Legendaries falls into four distinct types:
-
Static encounters — The Legendary waits at a fixed map location. The player initiates battle by interacting with it. If the Pokémon faints or the player flees, a soft reset (or in-game respawn mechanic) restores it. This is the format for Mewtwo in Cerulean Cave (Generation I), Kyogre and Groudon in their respective caves (Generation III), and Dialga/Palkia at Spear Pillar (Generation IV).
-
Roaming encounters — The Legendary moves across the map's region tiles after a trigger event. Raikou, Entei, and Suicune in Generation II introduced this system. The Pokémon's HP carries over between encounters, meaning a player who whittles it to low HP in one encounter can finish the capture next time. Roaming encounters are widely considered the most frustrating acquisition format due to their reliance on map RNG.
-
Forced capture encounters — Some games require catching a Legendary to advance the plot. In Generation V, Zekrom or Reshiram cannot be declined — the game loops the encounter until the capture succeeds. In Pokémon Legends: Arceus, the Noble Pokémon boss fights function similarly.
-
Post-story unlock encounters — Many Legendaries only appear after completing the main story. Mewtwo, Ho-Oh, Lugia, and most box Legendaries from later generations become accessible only once the credits roll. Tera Raid events in Scarlet and Violet added a fifth variant: time-gated online encounter windows for Legendaries like Mewtwo (the 7-star Tera Raid version introduced in late 2022).
Nature and IV optimization applies to all catchable Legendaries. Because they cannot breed, players who want specific natures or IVs must soft-reset the encounter — saving before the Legendary, attempting capture, then resetting if the result is unfavorable. The Synchronize ability (carried by a lead Pokémon) increases the chance of matching the Nature to 50% in most main-series games, a mechanic confirmed by Game Freak's own in-game documentation.
Shiny Legendaries are possible in most games, but odds vary. The base shiny rate of 1 in 4,096 (since Generation VI) applies to most static encounters unless shiny-locked. For a full breakdown of shiny encounter odds and methods, the shiny Pokémon hunting guide covers every available probability boost.
Common scenarios
The three scenarios players encounter most often:
Box Legendary capture — The Legendary featured on a game's box art (Charizard, Rayquaza, Zacian, Koraidon, etc.) is almost always mandatory or nearly unavoidable. These are designed as story climaxes. Most are not shiny-locked in their original games, though some remasters and ports have changed this.
Version exclusives — Legendaries like Dialga and Palkia, or Zacian and Zamazenta, are split across version pairs. Trading or using the Pokémon HOME service (Nintendo's cloud storage platform) is required to complete a Legendary Pokédex without owning both versions.
Returning Legendaries in later games — Titles like Omega Ruby/Alpha Sapphire and Sword/Shield's Crown Tundra DLC aggregated Legendaries from past generations into single games. The Crown Tundra specifically included Dynamax Adventures, a cooperative dungeon format where Legendaries appear at the end of a raid den chain — with a 100% capture rate on the first encounter of each species.
Decision boundaries
Knowing which Legendary to pursue first requires understanding the competitive and collectible dimensions of the roster. Base stat totals for most Legendaries fall between 570 and 680, but raw power varies dramatically by typing and movepool. For competitive contexts, the Pokémon tiers and Smogon rankings page covers Legendary placement in standard and Ubers formats.
For collectors, condition and provenance matter differently than for battlers. A Legendary obtained via a legitimate event distribution carries verifiable origin data (Original Trainer name, met location, fateful encounter flag) that distinguishes it from a hacked equivalent. The Pokémon IV breeding guide covers how to evaluate stat legitimacy, though the principle applies to bred and caught Pokémon alike.
