PART ONE — THE WORLD

The inhabited world is spread across several landmasses separated by ocean, connected by ferry lines, cycling roads, flight paths, and increasingly by high-speed rail. Two of these landmasses sit close enough together to share a single stretch of mountains and a land border — Kanto and Johto — while the rest are reached only by sea or air: Hoenn's island-studded waters, the compact northern landmass of Sinnoh, the distant transoceanic expanse of Unova, the hexagonal landmass of Kalos, the tropical island chain of Alola, the island nation of Galar, and the sun-drenched peninsula of Paldea.

Each region runs its own government, currency (though the Pokémon Dollar is near-universal as a medium of exchange), school system, and Pokémon League, and each has its own patron professor who issues starter Pokémon to newly licensed trainers. Despite that independence, the regions are bound together by a shared culture of Pokémon training: badges, League conferences, an International Police that pursues cross-border criminal syndicates, and a research community that freely publishes findings through outlets like the regional Pokédex projects. A trainer who grows up in one region and travels to another is a completely unremarkable sight.

Latitude and climate vary enormously between regions — from the near-arctic peaks of northern Sinnoh to the equatorial beaches of Alola — which has produced very different ecologies, architecture, and ways of life from place to place, even though every region shares the same basic relationship between people and Pokémon.

PART TWO — THE REGIONS

Kanto

Geography. Kanto occupies the eastern end of a large northern landmass it shares with Johto, from which it is separated by the peaks of Mt. Silver and the connecting pass at Route 28. It sits at temperate, mid-northern latitudes, giving it four distinct seasons. The region is a patchwork of dense urban centers (Saffron, Celadon, Vermilion) and quieter countryside (the Viridian Forest, the farmland around Pallet Town and Cerulean), bounded by Mt. Moon to the northwest, the volcanic Cinnabar archipelago to the south, and the long western coastline facing the open sea. Diglett's Cave and the tunnel systems beneath Route 2 and Route 11 riddle the region's bedrock with underground passages.

Ecology. Kanto's temperate mix of forest, farmland, coastline, and mountain gives it one of the broadest ranges of endemic Pokémon of any region — Bug-types thick in Viridian Forest, Water-types along the coasts and in Cerulean Cave, Rock and Ground-types in Mt. Moon and the Rock Tunnel, Grass-types around Celadon's greenhouses and Pallet's farmland. The Safari Zone east of Fuchsia preserves a curated cross-section of this biodiversity for research and recreation. Cinnabar's now-dormant volcano and the nearby Seafoam Islands support a distinct pocket of Fire- and Ice-type life within a few miles of each other.

Culture. Kanto is widely regarded as the cradle of modern Pokémon training culture — the Pokémon League format, the professor-and-starter tradition, and the trainer's journey as a rite of passage all trace back to institutions based here, particularly Professor Oak's research lab in Pallet Town. Its cities lean industrial and commercial (Saffron's Silph Co. headquarters, Celadon's department stores, Vermilion's shipping port), while its outlying towns keep a slower, rural pace. Cycling is a genuine subculture, complete with a dedicated cycling road connecting Cerulean and Fuchsia.

How others see it. Neighboring regions tend to view Kanto as tradition-minded and a little conservative — the place training "started," and proud of it — respected for its institutions but sometimes teased by younger regions for treating its own conventions as the default the rest of the world should follow.

---

Johto

Geography. Johto sits just west of Kanto on the same landmass, connected by the mountain pass at Mt. Silver. Its terrain is hillier and more rural than Kanto's, dominated by the Ruins of Alph's plateau, the Ice Path's frozen caverns in the north, and the long coastal stretch running from Olivine to Cianwood. Its latitude is similar to Kanto's, though its interior highlands run noticeably colder in winter.

Ecology. Johto's older, less-developed terrain supports species tied closely to ancient sites — Unown cluster in the Ruins of Alph, while the Sudowoodo and Sentret common along its roads reflect a still heavily wooded interior. The Whirl Islands off Cianwood and the deep waters near the Lake of Rage host distinctive aquatic life, and the Ice Path is one of the few naturally ice-bound cave systems on the whole northern landmass.

Culture. Johto carries a strong sense of history and reverence for tradition — Bellchime Trail's temple bells, the Tin Tower and Bell Tower of Ecruteak, and the Kimono-dance lineage of Ecruteak's dancers all point to a region that treats its shrines and folk customs as living culture rather than museum pieces. Breeding is practically a regional specialty; the Day Care system that lets trainers everywhere breed Pokémon eggs originated on Route 34 outside Goldenrod. Goldenrod itself is Johto's commercial heart, home to the region's largest department store and a radio tower that broadcasts across both Johto and Kanto.

How others see it. Johto is generally seen as Kanto's quieter, more contemplative twin — respected for preserving customs (particularly around shrines and legendary Pokémon) that other regions let fade, though sometimes characterized by outsiders as sleepy or old-fashioned.

---

Hoenn

Geography. Hoenn is a scattered, subtropical region built as much from sea as from land — a long, curling landmass fringed with dozens of small islands, positioned at lower latitudes than Kanto or Johto, giving it a warm, humid, monsoon-prone climate. Mt. Chimney's active volcano dominates the north, Sootopolis City sits inside the crater of an ancient one, and the Hoenn interior alternates between dense jungle (Petalburg Woods, Fortree's treetop settlements) and arid basin (the Route 111 desert). The region is also seismically restless, with the ancient legend of Groudon and Kyogre tied directly to its land-versus-sea geological instability.

Ecology. Hoenn's split personality — half ocean, half jungle — gives it the richest Water-type diversity of any region, alongside deep jungle Grass- and Bug-type populations and volcanic Fire- and Rock-type life around Mt. Chimney and Lavaridge. The Seafloor Cavern and underwater route near Sootopolis are unique in being fully submerged, explorable habitats.

Culture. Hoenn's culture is outward-facing and environmentally minded — Fortree's houses are built in the treetops to preserve the forest floor, Mauville is a hub of engineering and bicycle culture, and the region hosts Pokémon Contests, a beauty-and-skill competition format that treats a Pokémon's condition and performance as seriously as its battle strength. Weather itself is practically a character in Hoenn's culture, thanks to its history of real droughts and storms tied to its legendary Pokémon.

How others see it. Outsiders often view Hoenn as nature-obsessed and community-oriented, admired for its conservation ethic (the Devon Corporation's research into weather and geology is regionally famous) but occasionally seen as isolated, given how much of its interior is only reachable by boat or dive gear.

---

Sinnoh

Geography. Sinnoh occupies a compact, mountainous northern landmass at high latitude, cold enough that its central peak, Mt. Coronet, stays snow-capped year-round and effectively splits the region into two halves connected only by a handful of mountain routes. The northern half (Snowpoint, Lake Acuity, the Route 217/Route 216 snowfields) is subarctic; the southern half (Sandgem, Jubilife, Hearthome) is temperate and considerably milder. Sinnoh is also unusually dense with caves and ancient ruins — Solaceon's catacombs, the Snowpoint and Hearthome temples, and Spear Pillar high on Mt. Coronet among them.

Ecology. The north-south divide gives Sinnoh sharply distinct ecologies within a single region: Ice- and Steel-type life in the snowbound north, temperate forest and farmland species in the south, and a notable concentration of Ghost-type Pokémon around Eterna Forest and the Old Chateau. The three lakes — Verity, Valor, and Acuity — are each treated as ecologically and spiritually significant sites in their own right.

Culture. Sinnoh is Johto's northern counterpart in its reverence for history, if anything more explicit about it — Canalave's library holds some of the oldest written records in the known world, including folk tales describing the earliest interactions between people and Pokémon. Hearthome hosts Super Contests (an evolution of Hoenn's Contest format) and the region's grandest temple. Snowpoint's isolated, deeply traditional community stands in contrast to the cosmopolitan bustle of Jubilife, the region's media and transit hub.

Historical note. Among the texts held in the Canalave library are the Sinnoh Folk Tales, three short stories describing the earliest relationship between people and Pokémon. The oldest of the three claims that, in the distant past, there was no real distinction between a person and a Pokémon — that both shared a single "spirit" — and that it was once ordinary for the two to marry one another. Most scholars treat this as origin folklore rather than literal history, on a level with other regions' creation myths, but it remains one of Sinnoh's most-discussed pieces of ancient literature.

How others see it. Sinnoh is regarded as the most mythologically serious of the older regions — a place where legends about creation, time, and space are treated with real weight — respected for its scholarship but seen by some as insular, given how much of the region remains cut off by Mt. Coronet's snow for parts of the year.

---

Unova

Geography. Unova lies across the ocean from the older regions, a solitary landmass built around a single sprawling metropolis, Castelia, with the rest of the region — farmland, gorges, deserts, and a chain of northern mountains — spreading outward from it. Its climate is temperate to cold, growing markedly harsher toward Icirrus and the Giant Chasm in the north. Unlike the tightly packed older regions, Unova's towns are spread far apart across genuinely large open stretches of plain and desert.

Ecology. Unova was the first region whose Pokémon population was drawn almost entirely from species unknown elsewhere at the time, giving it an unusually self-contained ecology: desert life around Relic Castle, industrial and urban-adapted species in Castelia's sewers and skyscrapers, and cold-climate specialists around the Giant Chasm and Twist Mountain. The region's Dragon-type population, centered on the Relic Castle-Reversal Mountain-Opelucid axis, is particularly prominent in local culture.

Culture. Castelia is a genuine metropolis — dense, diverse, and fast-moving, with the region's population, industries, and immigration concentrated there far more than in any single city elsewhere. Nimbasa is built around entertainment (a full amusement park and a Pokémon Musical theater), Driftveil is a working port and market town, and Opelucid preserves Unova's oldest Dragon-training traditions. Unova also has a documented, difficult recent history with a movement that argued Pokémon should be fully separated from human ownership — a debate that still surfaces in local politics and conversation.

How others see it. Because Unova sits apart from the older landmass, its people have historically been treated with a mix of fascination and wariness by trainers who grew up on Kanto-Johto customs — seen as innovative and cosmopolitan, but also as the region where the relationship between humans and Pokémon has been most openly, and sometimes contentiously, debated.

---

Kalos

Geography. Kalos forms a rough hexagon at temperate latitudes, with a mountainous, forested south (Route 5's chateau country, the Reflection Cave) giving way to open farmland and finally the flat northern plains around Lumiose City, the region's grand central capital. The Kalos Power Plant and the long-defunct war memorial beneath Geosenge Town point to a more turbulent history than the region's polished present suggests.

Ecology. Kalos's terrain supports species suited to formal gardens and managed woodland as much as true wilderness — Santalune Forest's Bug-types, the Fairy-type concentration around Reflection Cave and Shalour City (Kalos being the region where the Fairy type itself was first formally classified), and coastal life around Cyllage and Coumarine. Terminus Cave and the Sea Spirit's Den hold rarer, more isolated populations.

Culture. Kalos prizes beauty and craftsmanship above almost anything else — Lumiose is laid out like a grand European capital around a central tower, fashion boutiques and photography studios are common fixtures in every city, and Pokémon Showcases (Kalos's answer to Contests) judge elegance and performance. Shalour City's Tower of Mastery preserves the practice of Mega Evolution, a rare and demanding bond-based transformation historically associated with this region above all others.

How others see it. Kalos is broadly seen as the aesthetic and cultural capital of the known world — admired for its art, fashion, and cuisine, and sometimes gently mocked elsewhere as overly concerned with appearances and refinement.

---

Alola

Geography. Alola is a warm, volcanic island chain at low latitude — four main islands (Melemele, Akala, Ula'ula, Poni) plus the artificial Aether Paradise offshore — with a genuinely tropical climate year-round. Its isolation from the other regions by open ocean has shaped both its ecology and its culture profoundly.

Ecology. Island isolation has produced Alola's most distinctive biological feature: regional forms, where species found elsewhere have adapted so differently to Alola's climate and competition that they're barely recognizable relatives of their mainland counterparts (an Alolan Vulpix, for instance, is Ice-type rather than Fire-type, having adapted to Mt. Lanakila's snowy peak rather than a hot climate). Coral reefs, volcanic craters, and dense rainforest all sit within a short distance of each other on any given island.

Culture. Alola does not run a conventional Gym-badge League; instead, young trainers undertake the Island Challenge, a series of trials and grand trials overseen by trial captains and each island's kahuna, capped by a demanding right-of-passage battle. Community and hospitality are treated as close to sacred — the "aloha" spirit of welcome and generosity — and Pokémon are as often companions and family as they are battle partners. Aether Paradise, meanwhile, runs one of the world's most prominent Pokémon rescue and conservation operations.

How others see it. Mainland trainers sometimes underestimate Alola as laid-back or unserious about competitive training, right up until they face an Island Challenge graduate — Alolans themselves tend to see the mainland's badge-collecting model as needlessly rigid compared to their own trial system.

---

Galar

Geography. Galar is a compact island nation at temperate-to-cool latitude, split cleanly between an industrial south (Motostoke, Hammerlocke, the coal-and-steam heritage of the Wild Area's mining history) and pastoral, moor-and-loch countryside further north (Turffield, Circhester, the Crown Tundra beyond it). The Wild Area at its center is an unusually large stretch of unmanaged wilderness deliberately left undeveloped between the region's cities.

Ecology. The Wild Area's scale makes it one of the richest single wildlife habitats in the world, with weather that shifts by the day and draws different Pokémon accordingly. The Slumbering Weald's old-growth forest, the Glimwood Tangle's bioluminescent flora, and the Crown Tundra's glaciers each support their own tightly specialized populations.

Culture. Galar treats Pokémon battling as a full-blown national sport — Gym battles are held in packed stadiums with a Champion Cup tournament broadcast region-wide, closer in tone to a football final than a quiet duel. Motostoke and Hammerlocke carry heavy industrial-revolution styling, while Wyndon, the capital, is Galar's glittering modern showpiece. Circhester's baths and Ballonlea's fairy-tale aesthetic preserve older, more whimsical corners of the region's culture.

How others see it. Galar is generally seen as the most spectacle-driven, crowd-oriented Pokémon culture in the world — admired for how accessible and exciting it makes competitive battling, though some older regions consider its stadium culture a bit brash compared to their own quieter traditions.

---

Paldea

Geography. Paldea occupies a sun-warmed peninsula at temperate-to-warm latitude, its terrain built around the enormous Great Crater at its center — a mile-deep, ancient impact scar whose sheer walls dominate the region's skyline from almost anywhere. Around it spreads a landscape of dry plains, olive-and-vineyard hill country, coastal cliffs, and a southern desert, connected by open, unfenced countryside that trainers are free to explore in almost any order.

Ecology. Paldea's varied biomes — desert, wetland, mountain, coastline — give it one of the most naturally diverse Pokémon populations of any single region, and the Great Crater itself, plunging far below the surrounding terrain, hosts an entirely separate, ancient ecosystem cut off from the world above, including species displaced from both the deep past and a possible future.

Culture. Paldean life revolves heavily around food and education. Nearly every settlement, trail, and landmark is named for a dish or cooking term, and sharing a home-cooked picnic with one's Pokémon is a genuine daily ritual, not just a novelty. The region's two great academies — training grounds for young trainers that double as full schools — sit at the center of Paldean civic life, and a treasure-hunting tradition (searching out titan Pokémon, Team Star's reformed delinquents, and rare specimens) is treated as a rite of passage alongside more conventional Gym challenges.

How others see it. As one of the newest regions to open itself fully to outside trainers, Paldea is often seen as an exciting frontier — admired for its open-world freedom and its cuisine — while still working to build the same long-standing international reputation as the older regions.

---

Other Territories

A handful of smaller or historically distinct territories round out the known world. Hisui is the name once given to the Sinnoh landmass in the distant past, when it was a lightly settled frontier where people and Pokémon lived far more separately than they do today; the Galaxy Expedition Team's records from that era are treated as a foundational text for understanding how the modern trainer-Pokémon relationship came to be. Kitakami and the Blueberry Academy archipelago lie off Paldea's coast, the former a quiet, mountainous countryside steeped in old ghost-story tradition, the latter home to one of the world's most prestigious Pokémon academies, drawing students from every region. Further afield, the arid Orre region, largely uninhabited outside a handful of desert settlements, is best known for its history of Pokémon-focused organized crime and the harsh landscape that made such activity possible.

PART THREE — WORLDBUILDING ELEMENTS

Poké Balls

A Poké Ball is a spherical containment device that converts a Pokémon into a stable energy form for storage and transport. In practice, a trainer weakens a wild Pokémon through battle (or otherwise earns its willingness to be caught) and throws a ball at it; if the capture succeeds, the Pokémon is held in stasis inside until released. A caught Pokémon can be recalled to its ball at will and is generally kept there only when not actively out and about — most trainers let their Pokémon walk, fly, or swim alongside them rather than staying balled up constantly.

Balls come in many specialized variants beyond the standard Poké Ball: the Great Ball and Ultra Ball offer progressively higher base catch rates; the Master Ball guarantees a catch outright and is exceedingly rare; the Quick Ball works best thrown in the first moment of an encounter, the Timer Ball the longer a battle drags on; the Net Ball and Dive Ball are tuned for Water- and Bug-types or underwater catches; the Dusk Ball for caves and nighttime; the Repeat Ball for species already registered to a trainer's Pokédex; the Heavy Ball for larger Pokémon; the Friend Ball, Luxury Ball, and Love Ball which affect a caught Pokémon's friendship rather than its catch odds; the Beast Ball, purpose-built for Ultra Beasts; and ornamental or ceremonial variants like the Premier Ball and Cherish Ball, often given out for special occasions rather than everyday catching.

Humans and Pokémon

The relationship between people and Pokémon runs through every layer of daily life — as working partners, athletes, companions, and family. Farmers use Pokémon to till fields and haul cargo; postal and courier services rely on Flying-types; police forces field Pokémon partners (Growlithe and its Hisuian relative Arcanine are especially associated with regional police work); fishing fleets, construction crews, and rescue services all lean on Pokémon suited to the job. Just as many Pokémon are kept purely as companions, with no battling or working role at all.

The formal profession of "Pokémon Trainer" — someone who travels, battles, and collects Gym Badges toward a League challenge — is really just the most visible thread in a much wider fabric of Pokémon-related careers: Breeders who raise and care for Pokémon, often running Day Cares that hatch eggs for trainers passing through; Coordinators and Performers who compete in Contests, Super Contests, or Showcases judging condition and presentation; Rangers who protect wild Pokémon and habitats without capturing them at all; Professors who research Pokémon biology and issue starters to new trainers; and Nurses and Officers — every region's Pokémon Centers are staffed by a healer known regionally as Nurse Joy, and community policing is likewise handled region-wide by officers known as Officer Jenny, a naming tradition so consistent that trainers rarely ask why every town's nurse and officer seem to share a face and a name with the last town's.

Historically, the line between "person" and "Pokémon" was drawn less sharply than it is now. Canalave City's library in Sinnoh preserves folk tales describing an era when people and Pokémon shared a single spirit and were, in the old telling, functionally the same kind of being — a period in which marriage between the two was recorded as ordinary rather than remarkable. Most scholars today treat this as origin mythology rather than literal history, but similar echoes appear in scattered folklore elsewhere in the world, usually framed as stories about a Pokémon taking human shape to live among people for a time before returning to the wild.

Pokémon Battles and the League System

A Pokémon battle is a structured contest between trainers, each directing one or more Pokémon through moves in alternating turns until one side's Pokémon are unable to continue. Formats vary — one-on-one Singles, two-on-two Doubles, four-trainer Multi battles, and the raid-style cooperative battles used against unusually powerful wild Pokémon — but the core exchange of move, effect, and counter-move is constant throughout.

Each region runs its own Pokémon League: a trainer proves themselves by defeating eight regional Gym Leaders (or, in Alola's case, completing the Island Challenge trials) to earn eight badges, which qualify them to challenge the Elite Four and finally the reigning Champion. Winning a League title is the closest thing the world has to a universal marker of elite skill, and Champions are treated as regional celebrities. Competitive battling below the League level runs on an honor system as much as a rulebook — a "type advantage" is common knowledge, but skilled trainers routinely win against unfavorable matchups through strategy, and deliberately fighting outside official rules (over-leveled Pokémon against child trainers, banned items, and so on) is broadly considered poor sportsmanship even where it isn't formally illegal.

Pokémon Centers and Regional Infrastructure

Every settlement of any size has a Pokémon Center, a free public clinic that heals injured or fainted Pokémon regardless of the trainer's home region, typically attached to a Poké Mart selling balls, potions, and other supplies. Centers double as informal community hubs — a trade terminal, a place to rest overnight, and often the first stop for any traveling trainer arriving in a new town. The consistency of this system across every region, run independently but to an identical standard, is one of the clearest signs of just how thoroughly Pokémon training culture unifies the world despite each region's political independence.

Regional Transformation Phenomena

Several regions have their own signature battle-transformation tied to local history or geology, each temporary and each drawing on a different source of power:

• Mega Evolution (associated above all with Kalos, though practiced in pockets elsewhere) is a bond-driven transformation requiring a specific Mega Stone and a compatible in-hand stone, the Key Stone, lasting only the duration of a battle.
• Z-Moves (Alola) channel energy stored in a Z-Crystal into a single overwhelming attack once per battle, performed with a distinctive ritual gesture between trainer and Pokémon.
• Dynamax and Gigantamax (Galar) use energy drawn from the Wild Area's Power Spots to grow a Pokémon to enormous size for three turns; Gigantamax is a rarer variant available only to certain bloodlines of a species, changing its appearance further still.
• Terastallization (Paldea) crystallizes a Pokémon and shifts its effective type to a personal "Tera Type" for the rest of a battle, powering up moves of that type while the Pokémon otherwise keeps its normal defensive profile.

Eggs and Breeding

Most Pokémon reproduce via eggs, typically produced by leaving two compatible Pokémon together at a Day Care. Compatibility is organized loosely around Egg Groups — broad categories of body plan and reproductive compatibility that cut across species and even across some types — with a small number of Pokémon (most Legendary and Mythical Pokémon among them) unable to breed at all. Breeding is also the main route to passing down inherited traits like a parent's held Egg Move, particular stat tendencies, or in rare cases an unusual coloration.

Organizations of Ill Repute

Most regions have, at some point in their recent history, dealt with an organized group turning Pokémon toward criminal or extremist ends — smuggling and profiteering in Kanto and Johto, environmental extremism in Hoenn, ambition and space-time manipulation in Sinnoh, Pokémon liberation ideology in Unova, weapons research in Kalos, corporate exploitation dressed up as conservation in Alola, and localized delinquency in Paldea. The International Police coordinates across regional borders to track and dismantle these groups, and player-facing history treats their defeat as a fairly routine part of a given era's headlines rather than an ongoing present threat.

| Organization | Region | Core ideology/goal | |---|---|---| | Team Rocket | Kanto/Johto | Old-fashioned organized crime; profit through Pokémon theft and black-market trade | | Team Aqua / Team Magma | Hoenn | Environmental extremism — expand the sea, or expand the land, respectively | | Team Galactic | Sinnoh | Nihilistic desire to remake the universe by erasing emotion/spirit from it | | Team Plasma | Unova | Pokémon "liberation" — the belief that human–Pokémon partnership is inherently exploitative | | Team Flare | Kalos | Elitist "world beautification" through mass destruction and eugenic self-selection | | Team Skull / Aether Foundation | Alola | Team Skull: small-time delinquent dropouts; Aether Foundation: conservation-focused, complicated by its leadership's personal obsessions | | Macro Cosmos (under Chairman Rose) | Galar | Corporate over-reliance on a single energy source (Dynamax energy) to solve a long-term crisis | | Team Star | Paldea | Formerly bullied students turned truant rebels, organized defensively rather than out of grand ideology |

Most of these organizations are remembered regionally as significant, unsettling events in living memory rather than distant history — ordinary citizens in each region are generally aware of these organization's rise and fall, generally through generic news channels and public information, and have opinions about it.

PART FOUR — POKÉMON

Evolution

Evolution is a sudden change in a Pokémon's form and (usually) capabilities, distinct from the gradual growth that happens between evolutions. The most common trigger is simply reaching a threshold level while training, but many species evolve through other means:

• Friendship-based evolution, triggered once a Pokémon's bond with its trainer crosses a threshold, sometimes further gated by time of day.
• Trade-based evolution, triggered the moment a Pokémon changes trainers, in some cases only when holding a specific item during the trade.
• Stone-based evolution, triggered instantly by exposing a Pokémon to a specific evolutionary stone: Fire, Water, Thunder, Leaf, Moon, Sun, Shiny, Dusk, Dawn, and Ice Stones are the best known, each tied to a cluster of species rather than a single one. This is the closest thing to a "forced" or artificial evolution — no additional training or bonding is required, just the stone itself.
• Location-based evolution, triggered only in a specific place — near a magnetic rock formation, a mossy or icy boulder, or a particular cave.
• Move-based evolution, triggered by knowing (or, in a few cases, being taught in the moment) a specific move, sometimes combined with a friendship or location requirement.
• Stat- or condition-based evolution, where a Pokémon's evolved form depends on which of its stats is highest, its held item, its gender, the weather, or even the time of day it evolves.

Evolution is generally treated as permanent and is a personal choice on the trainer's part in most cases — many trainers deliberately keep a Pokémon in an earlier stage because they prefer its size, moveset, or temperament, and there's no social stigma attached to doing so.

Types

Every Pokémon (and every move) carries one of eighteen elemental types, and most Pokémon carry two, giving them a combined offensive and defensive profile. A type's effectiveness against another ranges from a double-damage "super effective" hit, through neutral damage, down to half-damage "not very effective," and in a handful of matchups, complete immunity.

| Type | Identity | Strong against | Weak against | Resists | Immune to | |---|---|---|---|---|---| | Normal | Adaptable, common, straightforward | — | Fighting | — | Ghost | | Fire | Combustive, passionate, transformative | Grass, Ice, Bug, Steel | Water, Ground, Rock | Fire, Grass, Ice, Bug, Steel, Fairy | — | | Water | Fluid, nurturing, relentless | Fire, Ground, Rock | Electric, Grass | Fire, Water, Ice, Steel | — | | Electric | Fast, energetic, unpredictable | Water, Flying | Ground | Electric, Flying, Steel | — | | Grass | Patient, restorative, territorial | Water, Ground, Rock | Fire, Ice, Poison, Flying, Bug | Water, Electric, Grass, Ground | — | | Ice | Pristine, isolating, fragile on defense | Grass, Ground, Flying, Dragon | Fire, Fighting, Rock, Steel | Ice | — | | Fighting | Disciplined, direct, physical | Normal, Ice, Rock, Dark, Steel | Flying, Psychic, Fairy | Bug, Rock, Dark | — | | Poison | Corrosive, defensive, opportunistic | Grass, Fairy | Ground, Psychic | Grass, Fighting, Poison, Bug, Fairy | — | | Ground | Grounded, sturdy, foundational | Fire, Electric, Poison, Rock, Steel | Water, Grass, Ice | Poison, Rock | Electric | | Flying | Free-ranging, agile, hard to pin down | Grass, Fighting, Bug | Electric, Ice, Rock | Grass, Fighting, Bug | Ground | | Psychic | Cerebral, perceptive, esoteric | Fighting, Poison | Bug, Ghost, Dark | Fighting, Psychic | — | | Bug | Numerous, industrious, easily underestimated | Grass, Psychic, Dark | Fire, Flying, Rock | Grass, Fighting, Ground | — | | Rock | Ancient, tough, brittle in a fight | Fire, Ice, Flying, Bug | Water, Grass, Fighting, Ground, Steel | Normal, Fire, Poison, Flying | — | | Ghost | Elusive, mischievous, boundary-crossing | Psychic, Ghost | Ghost, Dark | Poison, Bug | Normal, Fighting | | Dragon | Powerful, rare, mythic weight | Dragon | Ice, Dragon, Fairy | Fire, Water, Electric, Grass | — | | Dark | Cunning, self-interested, night-associated | Psychic, Ghost | Fighting, Bug, Fairy | Ghost, Dark | Psychic | | Steel | Armored, industrious, unyielding | Ice, Rock, Fairy | Fire, Fighting, Ground | Normal, Grass, Ice, Flying, Psychic, Bug, Rock, Dragon, Steel, Fairy | Poison | | Fairy | Whimsical, protective, old-magic | Fighting, Dragon, Dark | Poison, Steel | Fighting, Bug, Dark | Dragon |

A dual-type Pokémon combines both of its types' profiles defensively — a matchup that's super effective against both of its types hits for quadruple damage, while a type it resists on both sides can end up taking as little as a quarter of normal damage, or none at all if one of its types is outright immune.

There is also a nineteenth type-adjacent classification, the Stellar type, which only exists as a temporary Terastallization result rather than a natural typing — no Pokémon is born Stellar-type. A Terastallized Stellar Pokémon keeps its original type's weaknesses and resistances defensively, but its attacks of any type get a one-time power boost, and Stellar-type moves themselves are especially effective against other Terastallized opponents.

Classification Tiers

Beyond the standard species classification, a handful of informal, colloquial tiers are used to talk about especially rare or powerful Pokémon. None of these are strict biological categories — they're closer to cultural shorthand, and the exact boundaries between them are debated even among researchers.

Legendary Pokémon are individually renowned, usually singular or paired/trio individuals whose existence is treated as established fact — there's physical evidence for them (shrines, statues, historical records, direct sightings) and many are directly credited with shaping natural phenomena or historical events in a given region: the creation of matter, space, and time in Sinnoh; the control of weather and geology in Hoenn; the guardianship of individual islands in Alola. Most Legendary Pokémon can't breed and have no confirmed gender.

Mythical Pokémon sit a tier rarer still. Where Legendaries are documented, Mythicals are the subject of folklore and rumor more than direct record — creatures like Mew, Celebi, or Jirachi are known mostly through old stories, sparse sightings, or singular historical anecdotes, with no broad physical evidence of the kind Legendaries have. Most people who know of a Mythical at all know it only as a story their grandparents told them.

Pseudo-legendary is a purely colloquial nickname — never an official category — for a specific pattern: a three-stage evolutionary line, usually Dragon-type, that reaches unusually high combined stats without ever being formally classified as Legendary. Dratini's line, Larvitar's, Bagon's, Gible's, Deino's, Goomy's, Jangmo-o's, Dreepy's, and Frigibax's lines are the trainers' standard examples, one in nearly every region.

Ultra Beasts are a separate classification entirely from Legendary or Mythical status — creatures that don't originate from this world at all, but arrive through breaches from a separate dimension known as Ultra Space, first documented in numbers around Alola. They're cataloged individually by researchers under provisional "UB" codenames before their proper names are confirmed, treated with a mix of scientific fascination and caution given how unpredictable their behavior can be outside their home environment.

Paradox Pokémon are a more recent classification out of Paldea's Great Crater: creatures that closely resemble known species but appear to be temporally displaced, either strikingly ancient, primal-looking "past" forms or sleek, technological-looking "future" forms of a familiar Pokémon. Their exact origin is still an active subject of study, tied closely to the anomalies inside the crater itself.
