Hisuian starters: how three familiar faces became regional forms
The phrase “hisuian starters” usually points to the trio of Pokémon that Game Freak rebuilt for Pokémon Legends: Arceus, the action-RPG set in the ancient Sinnoh region renamed Hisui. The Rowlet, Cyndaquil, and Oshawott lines were the only starter options at launch, and each received a regional form with new types, new evolutions, and a visual identity shaped by the colder, more isolated setting. For developers, designers, and players who care about how the changes were built, the hisuian starters are a small but unusually complete case study in regional form design: how a new silhouette, a new type pair, and a new evolutionary branch can be added to an existing creature without breaking the familiar one.
This article treats the hisuian starters as both a player-facing reference and a GameDev topic. The first half covers what each line actually does in battle, how it evolves, and how the new designs connect to Hisui’s environment. The second half looks at the production context: how regional forms fit into a creature-collection system, how a team decides when an old line is worth revisiting, and what the hisuian starters reveal about the design space around type changes and evolutionary branching.
What “regional form” actually means in the series
A regional form, sometimes called a regional variant, is a creature that uses the same base species and Pokédex number as an existing Pokémon but looks and behaves differently because of the region it lives in. The mechanic was introduced in Pokémon Sun and Moon with the Alolan forms and expanded heavily in Legends: Arceus and later entries. Regional forms can have a new type, a new ability, different stats, and a different evolutionary line, but they remain the same species in the Pokédex for sorting, storage, and breeding rules.
For the hisuian starters, the regional treatment is more aggressive than the original Alolan set. Each line changes primary type, each gains a new evolution, and one line, Oshawott, becomes a single-stage independent form at the highest level rather than gaining a third stage. The changes are significant enough that players had to relearn the type matchups, and developers had to make sure the older forms were not invalidated in the same game or in cross-generation transfers.
The three hisuian starters at a glance
The three lines behave very differently in practice, and the comparison is the cleanest way to see how much design space a regional form can cover. The table below summarizes the final-stage hisuian starters and how they differ from their familiar counterparts.
| Starter line | Final stage | Hisuian type | Original type | Notable change |
|---|---|---|---|---|
| Rowlet | Hisuian Decidueye | Grass / Fighting | Grass / Ghost | Swapped Ghost for Fighting, gained a Fighting secondary type |
| Cyndaquil | Hisuian Typhlosion | Fire / Ghost | Fire | Gained Ghost typing instead of staying pure Fire |
| Oshawott | Hisuian Samurott | Water / Dark | Water | Gained Dark secondary type, lost its middle evolution stage |
All three lines share a thematic emphasis on cold-climate features: longer plumage, heavier shells, and silhouettes that read as more guarded or ceremonial than their Johto or Unova counterparts. The visual differences are deliberate, not decorative, and they line up with the type shifts. A purely Fire line would feel out of place in a region built around snowfields and volcanic ridges, so the Ghost and Dark additions help each creature fit the world that surrounds it.
Rowlet line: from Ghost archer to Grass and Fighting brawler
Rowlet and its middle stage Dartrix look almost identical between the regular and Hisuian forms at the base of the line. The obvious change is reserved for the final evolution. Hisuian Decidueye keeps the Grass typing but drops Ghost in favor of Fighting, which changes both its move pool and its role in a player’s party.
In a typical playthrough, the swap from Ghost to Fighting is the most consequential decision. Ghost offered immunities to Normal and Fighting, plus a useful set of utility moves. Fighting replaces those with resistance to Dark, Bug, and Rock, and unlocks a different category of physical attacks. The result is a final-stage starter that hits harder on the physical side and fits a more aggressive melee-archer fantasy than the original line’s spectral precision role.
For developers, the Rowlet line is the cleanest example of a type swap that does not invalidate the original form. Players who have used a Ghost and Grass Decidueye in earlier games can still use it; Hisuian Decidueye is a parallel option rather than a replacement. That distinction is important in a live-service-style creature ecosystem where long-term collection and trading matter.
The base stats also shift to match the new role. The Hisuian line leans harder into Attack, while the original line leaned into Special Attack. The split mirrors the type change: Ghost is usually a special-offensive type, while Fighting is usually a physical-offensive type. Players who built a Calm or Modest Decidueye in earlier games will find that a Jolly or Adamant nature is more effective for the Hisuian variant. The internal data record still lives under the same species ID, which is why breeding, Pokédex sorting, and storage rules treat the two forms as one creature.
Cyndaquil line: a Fire starter that learned to be a Ghost
The Cyndaquil line was the surprise of the original reveal. Typhlosion had been a pure Fire type since Generation II, and changing it to Fire and Ghost was a significant departure for a starter. Hisuian Typhlosion keeps the Fire typing as its primary element and adds Ghost as a secondary, which preserves the familiar offensive role while opening new utility options.
The Ghost addition is also where the visual redesign lands hardest. Hisuian Typhlosion’s flames are recolored to a pale purple, and the long neck fur gives the creature a more spectral silhouette that matches the new typing. The change is more than cosmetic: Ghost typing provides a Normal immunity and a Fighting resistance, both of which change which matchups feel safe. The Fire half of the typing is unchanged, so the line’s elemental identity is still recognizable to long-time players.
From a production standpoint, Cyndaquil is the line that takes the most design risk. A starter is supposed to introduce new players to the type chart, and a Fire and Ghost starter introduces Ghost concepts very early. The team mitigated that by placing the reveal late in the game’s marketing and by giving the new form an evolutionary transition that visually matches the new type. The result is a starter that feels familiar to veterans and a little uncanny to newcomers, which is a useful tone to land in a Hisui-themed game.
The ability slot also changes for the Hisuian form. Where the original Typhlosion had access to Flash Fire, the Hisuian form can run Frisk as a normal ability, which adds a small scouting bonus at the start of each battle. The hidden ability slot differs again, and the move pool includes a handful of Ghost-type attacks that the original line never had. The result is a Typhlosion that occupies a different tactical niche without losing the Fire-type identity that defines the line.
Oshawott line: the line that lost a stage on purpose
Hisuian Oshawott is the smallest visual change among the three. Hisuian Samurott, on the other hand, is a complete redesign that drops Dewott, the middle stage, and produces a final evolution with a more armored, samurai-flavored silhouette. The most important gameplay change is the addition of Dark typing, which replaces the line’s pure Water identity with Water and Dark.
The loss of Dewott is unusual for a regional form. Most evolutionary branches in the franchise preserve the stage count to avoid surprising players who expect a fixed number of evolutions. By skipping a stage entirely, the line communicates that the Hisuian environment is a place where familiar creatures can grow differently, not just look different. The design choice also frees up party slots and reduces the cost of raising the line from start to finish.
For developers, the Oshawott line is a useful reminder that regional form work is not just about new sprites and new types. Sometimes the right decision is to remove a stage, change the timing of evolution, or otherwise alter the player’s relationship with the line. The decision has to be justified in the world’s fiction, and in the case of the hisuian starters, the setting’s emphasis on solitude and survival gives the team a defensible reason to make that change.
Hisuian Samurott also swaps its signature move set. Where the original Samurott leaned on Hydro Pump and Megahorn as its standout attacks, the Hisuian form gains access to Dark-type moves that complement its new typing. Players who built around a special Water cannon will find that the Hisuian form is a more physical attacker with a stronger emphasis on close-range engagements. The base stat block shifts accordingly, and the experience curve flattens slightly because the line has one fewer stage to grind through.
How the hisuian starters were designed for Hisui
Regional forms are not just art revisions. They require changes to creature data, type tables, ability definitions, evolution conditions, and in some cases move pools. The hisuian starters sit at the heavier end of that workload because each one changes type and each one alters the evolutionary line.
Connecting the new forms to Hisui’s environment
Hisui is presented as a colder, more isolated version of Sinnoh. Most of the available creature designs lean into either more rugged survival traits or more cultural, ceremonial traits tied to the lore. The hisuian starters follow the cultural branch. The new forms are not dressed in fur; they are styled as if the line had been part of a more formal, hierarchical society.
For developers, this matters because it sets expectations for future regional forms. A region with a strong cultural identity can justify type changes that do not seem to follow from the local climate alone. The hisuian starters justify their changes by linking them to legends and ceremonies, not by arguing that cold weather turns Fire into Ghost.
The ceremonial framing also shows up in the in-game text. NPCs in Legends: Arceus describe the hisuian starters in terms of ritual roles: a guardian archer, a mourner’s flame, and a sworn blade. The descriptions do not explain the type changes in mechanical terms, but they give the player a narrative hook for why the forms look and behave the way they do. That kind of in-fiction justification is the difference between a regional form that feels earned and one that feels like a marketing event.
Type changes as a way to keep older lines relevant
One of the more interesting production reasons to create regional forms is to keep older creatures relevant in a game with a smaller, more curated roster. Legends: Arceus did not include every creature from the Sinnoh Pokédex, so the development team needed ways to make the available lines feel fresh. The hisuian starters do that work by giving familiar names a new toolkit and a new matchup profile, which extends the perceived variety of the available roster without adding entirely new species.
That logic also applies to the wider regional-form pattern in the franchise. Rather than treating each new region as a chance to add new creatures only, regional forms let the team revisit old designs and reframe them for new contexts. The hisuian starters are the most visible example of that approach, but the same pattern shows up in Alolan Exeggutor, Galarian Weezing, and Paldean forms introduced in later generations.
There is a quiet cost to that approach, though. When a regional form is significantly stronger or more interesting than the original, players can read the older form as obsolete. Game Freak has tried to avoid that outcome by keeping the original forms in the code, by giving them access to moves that the regional form does not have, and by ensuring that the regional form has its own weaknesses. The hisuian starters follow that rule: each new form gains a type and loses something else, so the original line is not simply worse.
Using the hisuian starters in a playthrough
Players who are still deciding which hisuian starter to pick usually fall back on type preference, but the actual decision is more nuanced. The table below summarizes practical considerations that go beyond type matchups, including the in-game locations of the new evolutions and the rough role each final form plays in a party.
| Starter | Final stage | Where the new evolution is found | Party role | Key coverage |
|---|---|---|---|---|
| Rowlet | Hisuian Decidueye | Evolves at the usual level with a different typing | Physical attacker, mid-range combatant | Grass and Fighting-type moves, useful against Dark, Ice, and Steel |
| Cyndaquil | Hisuian Typhlosion | Evolves at the usual level with a different typing | Special attacker, ranged combatant | Fire and Ghost moves, useful against Psychic and Grass, immune to Normal |
| Oshawott | Hisuian Samurott | Evolves at the usual level with a different typing, skipping a stage | Physical attacker, frontline combatant | Water and Dark moves, useful against Ghost and Psychic, resisted by Fighting and Bug |
Players who want a safer first run often pick the line whose type pair they have used before. Hisuian Typhlosion is the closest to a classic Fire starter, and Hisuian Samurott keeps a Water identity with a more aggressive flavor. Hisuian Decidueye is the most different from its original form and tends to suit players who like physical, close-range combat.
When to evolve each line
All three hisuian starters evolve at the same levels as their non-Hisuian counterparts, with one structural exception: the Oshawott line jumps from Oshawott directly to Hisuian Samurott, skipping Dewott. Players who expect a middle stage should plan around that. The other two lines keep their middle stages, so a typical mid-game party composition will include a Dartrix and a Quilava alongside a Samurott if the player is willing to delay evolution.
Evolution timing matters because the hisuian starters gain access to new moves as they level. Holding a middle stage longer can be useful for learning certain attacks earlier, and pushing for the final evolution is usually the goal once the player is in the late game. None of the hisuian starters require a special item or condition to evolve, which keeps the player-facing logic simple.
Players who want to optimize the early game should keep an eye on the level ranges of the Noble Pokémon and the late-game requests. The hisuian starters hit their final evolutions well before those encounters, so a player who delays evolution for move-pool reasons is not punished by missing key story content. The only practical cost of delaying is a few extra minutes of grinding, which is usually a small price for a better moveset on the final form.
Team synergy and coverage
All three lines are usable through the main story, and the choice rarely locks the player out of anything important. The remaining party slots usually end up filled by creatures that cover the chosen starter’s weak matchups. A Grass and Fighting pick, for example, wants help against Flying and Fire, while a Fire and Ghost pick wants help against Water and Rock.
Practical coverage rules to keep in mind:
- Hisuian Decidueye’s Fighting typing gives it useful neutral coverage against Dark, Ice, Steel, and Rock.
- Hisuian Typhlosion’s Ghost typing unlocks immunities to Normal and Fighting and adds super-effective damage against Psychic and Ghost.
- Hisuian Samurott’s Dark typing gives it a clean answer to Ghost and Psychic, which are common threats in the late game.
Players who want to build a balanced team should pick the starter whose weak matchups they find easiest to cover with the rest of the available roster. The game gives enough alternative creatures that no single starter is a hard lock. Players who want to lean into a thematic team can also build around the chosen starter’s element: a Water and Dark starter pairs naturally with Ghost and Bug lines, while a Fire and Ghost starter pairs well with Ground and Dark lines that shore up the Water weakness.
How the hisuian starters compare to Alolan and Galarian starters
The hisuian starters are the third major example of regional starter variants, after the Alolan starters in Sun and Moon and the Galarian starters in Sword and Shield. Each set has its own design rules, and the differences are useful for thinking about how the series treats starters across regions.
| Region | Starter trio | Type changes vs original | New evolutions | Design emphasis |
|---|---|---|---|---|
| Alola | Rowlet, Litten, Popplio | None for the starters themselves; regional forms applied to other lines | None added | Tropical climate, no type changes for the starters |
| Galar | Grookey, Scorbunny, Sobble | None for the starters; the regional forms targeted other lines | None added | Industrial England-inspired setting, no type changes for the starters |
| Hisui | Rowlet, Cyndaquil, Oshawott | All three final forms change type | New evolutions for the Cyndaquil and Oshawott lines; Rowlet retains its evolution but with a new typing | Cultural reinterpretation of familiar lines, type changes for all three |
The pattern is clear. The Alolan and Galarian starter trios kept their type identities, while the hisuian starters all change type at the final stage. From a design standpoint, that is a meaningful escalation. Changing one starter’s type is a statement; changing all three is a deliberate choice to reframe what a starter can be in a given region.
The Galarian starters introduced a different kind of change: each line had a new final evolution with a new type, but the type change was tied to the new evolution rather than to a regional form. Galarian forms on non-starter lines, like Galarian Ponyta or Galarian Weezing, are the closer comparison to the hisuian starters. The difference is that the hisuian starters are pulled from earlier generations, while the Galarian non-starter forms are pulled from the same generation as the regional game. That distinction changes how familiar the changes feel to long-time players.
What this pattern tells developers
Developers who study regional forms can use the hisuian starters as a reference for how far a regional variant can be pushed. The team kept the base species and the early stages recognizable, but used the final evolution to change type, change silhouette, and change the player’s mental model of the line. That balance is a useful template for any project that revisits existing content for a new setting: keep the recognizable core, change the most visible element, and let the rest follow.
The hisuian starters also show that type changes are not a free decision. Each type swap changes the line’s matchup profile, its move pool, and the kinds of players who will prefer it. The team’s willingness to make that change for all three starters at once is a strong signal that the design brief for Hisui was unusual for the franchise.
There is also a useful lesson about timing. The hisuian starters were released in a game that sat between mainline generations, which gave the team a way to test aggressive regional form work without committing the entire mainline roster to those changes. Smaller, spinoff-style releases can be a low-risk place to push a system further than it would normally go, and the hisuian starters are a good example of that pattern.
The hisuian starters in a wider GameDev context
Outside of the franchise itself, the hisuian starters are useful as a teaching example for creature-design systems. The lines demonstrate how a small set of rules, like the regional-form system, can be reused to produce large amounts of fresh content without adding entirely new species. That pattern shows up in many games, including gacha titles, monster-collecting RPGs, and even some hero-shooter rosters.
Why regional forms are a useful content pattern
Regional forms let a development team keep creature data structures stable while changing the player-facing surface area. The same species record can host two or more visual and gameplay variants, and the type table can branch at the form level rather than at the species level. For a project with limited creature slots, that structure is a way to expand the player’s experience without exploding the internal catalog.
The pattern works best when each variant has a clear narrative reason. The hisuian starters justify their changes with the cold climate, the cultural setting, and the story beats around Hisui. Without that justification, regional forms can feel like a cosmetic reskin, which the franchise has occasionally been criticized for. The hisuian starters avoid that criticism by changing type, evolution, and silhouette, not just texture.
Another advantage of the pattern is that it gives the art team a starting point. Instead of designing a new creature from scratch, the artists can iterate on an existing model, which usually costs less time and lets the team deliver more variants per production cycle. The trade-off is that the variants are constrained by the original design, and the team has to accept that some changes will be subtler than others. The hisuian starters sit on the more aggressive end of that spectrum.
Trade-offs and limits of the pattern
The regional-form approach has trade-offs. A new form usually means new art, new animations, new stat data, and new move-pool testing. The hisuian starters required all of that for three final stages, plus a new middle stage for Oshawott, which is a non-trivial production load. Teams that want to use the pattern at scale have to plan for that cost, including the QA time needed to confirm that the new forms do not break older content.
There is also a balance problem. If every region adds multiple regional forms to the same lines, the older forms start to feel like placeholders. The hisuian starters are careful to give the Hisuian forms their own identity rather than treating them as upgrades. That distinction keeps both forms relevant and gives players a reason to engage with the older content in long-running collections.
A final limit is communication. Regional forms are easier to introduce when the marketing can lean on a familiar base design. If the base line is obscure, players may not recognize the regional form as a variant at all, and the design effort can be wasted. The hisuian starters benefit from being drawn from Generation II and Generation V, two of the franchise’s most-played generations, which gives the marketing a built-in hook.
Production notes and designer takeaways
For a designer reading the hisuian starters as a case study, the most useful takeaway is that regional forms are a system, not a feature. The system is the set of rules that lets an existing species branch into a new variant, and the hisuian starters push every part of that system: type, evolution, ability, and silhouette. Treating the system as a single design surface, rather than as a list of independent tweaks, is what lets the team make changes that feel coherent.
It also helps to separate the public-facing description of a regional form from the internal data record. The Pokédex still treats the Hisuian forms as the same species, which means storage, breeding, and trading rules do not have to be rewritten. The visual and gameplay changes ride on top of that stable record, and the team can iterate on the public surface without disturbing the underlying data. That separation is useful in any long-running content system, from creature collections to hero rosters.
Finally, the hisuian starters are a reminder that risk and familiarity are not opposites. The line designs are recognizable to anyone who played Pokémon Gold and Silver or Black and White, but the type changes are large enough to surprise even veteran players. The team kept the recognizable core and changed the most visible element, which is a useful template for any project that revisits existing content for a new setting.
Frequently asked questions
What are the hisuian starters in Pokémon Legends: Arceus?
The hisuian starters are the regional forms of Rowlet, Cyndaquil, and Oshawott introduced in Pokémon Legends: Arceus. Each line has a new type at the final stage, and the Cyndaquil and Oshawott lines also receive new final evolutions. The full discussion is in the section above covering how the regional forms connect to Hisui’s environment.
How do the hisuian starters change type compared to the original lines?
Hisuian Decidueye is Grass and Fighting instead of Grass and Ghost. Hisuian Typhlosion is Fire and Ghost instead of pure Fire. Hisuian Samurott is Water and Dark instead of pure Water. The type changes are summarized in the table earlier in this article.
Do the hisuian starters evolve at the same levels as the originals?
Rowlet and Cyndaquil keep their usual two-stage evolution chain. The Oshawott line is the exception: Hisuian Samurott evolves directly from Oshawott and skips Dewott, which is unusual for the franchise and a deliberate part of the regional-form design.
Are the hisuian starters stronger than the originals?
Strength depends on the format and the moves available, but the type changes do not automatically make the hisuian forms better. Hisuian Decidueye trades Ghost utility for Fighting coverage, Hisuian Typhlosion gains Ghost utility while staying Fire-dominant, and Hisuian Samurott gains Dark coverage at the cost of pure Water identity. Each trade is intentional and reflects the new region’s design goals.
Can hisuian starters be transferred to other games?
Hisuian forms can be moved into other titles through the usual transfer and trading systems when the receiving game supports them. Players should check the specific entry’s compatibility list, since not every game accepts every regional form. The mechanics are outside the scope of this article, but the basic rule is that the receiving game has to recognize the form as a valid creature.
Why did Game Freak change the types of the hisuian starters?
The type changes tie the starters to Hisui’s cultural and environmental setting rather than just its climate. The team’s design brief leaned on lore and ceremony to justify the shifts, and the changes are large enough to make the new forms feel distinct rather than cosmetic. The article’s GameDev section above covers the production reasoning in more detail.
Which hisuian starter is best for a first playthrough?
There is no single best choice. Players who want a familiar Fire experience usually pick Cyndaquil, players who want a Water option with more punch pick Oshawott, and players who enjoy physical attackers pick Rowlet. The game is balanced around all three being viable through the main story.
Do the hisuian starters have hidden abilities?
Each final-stage hisuian starter has access to its own hidden ability, and the abilities match the new typings. Players who care about the specific ability should check the in-game summary or the official creature database, since the ability is part of the data record rather than the visual form.
How are the hisuian starters different from Alolan starters?
The Alolan starter trio in Pokémon Sun and Moon keeps the same type identities as the original lines. The hisuian starters all change type at the final stage, which is a more aggressive use of the regional-form system. The comparison table earlier in the article summarizes the differences.
What can developers learn from the hisuian starters?
The hisuian starters are a case study in how a small set of rules, like the regional-form system, can produce a large amount of new content. They show how a team can keep an existing species relevant in a new setting by changing type, evolution, and silhouette while preserving the base identity. The wider GameDev section above covers the trade-offs in more detail.
