Guide to All Fish Pokémon: Types, Abilities, and Battle Secrets
For gamers and Pokémon enthusiasts, fish Pokémon represent a diverse category of aquatic creatures found across every generation.
These water-dwelling species—ranging from the feeble Magikarp to the legendary Kyogre—are essential for completing Pokédexes, dominating water-based battles, and exploiting in-game fishing mechanics.
This guide catalogs all 36 fish Pokémon, detailing their types, abilities, weaknesses, generations, and hidden battle potential. Backed by gameplay data and competitive insights, you’ll learn to leverage their strengths while avoiding common training pitfalls.
What Defines a Fish Pokémon?
Fish Pokémon are characterized by piscine biology, including gills, fins, and aquatic habitats. Most are Water-type, but dual-types like Qwilfish (Water/Poison) or Whiscash (Water/Ground) add strategic depth.
Interestingly, 76% of fish Pokémon have the ability Swift Swim, boosting their speed during rain. They’re caught via fishing rods or surfing, with some like Feebas requiring niche locations.
Core Traits:
- Habitat: Oceans, rivers, or caves (e.g., Relicanth in underwater ruins).
- Evolution: Many evolve through leveling (e.g., Barboach → Whiscash), while others need items (e.g., Seadra + Dragon Scale > Kingdra).
- Rarity Tier: Goldeen is common (Tier 1), while Shellder demands high Fishing Levels (Tier 3-4).
Why Use Fish Pokémon? Key Benefits
- Type Coverage: Water attacks hit Fire, Rock, and Ground types super-effectively. Dual-types like Lanturn (Water/Electric) negate standard Electric weaknesses.
- Rain Teams Dominate: Swift Swim users like Barraskewda double speed during rain, enabling sweeps.
- High Survivability: HP averages 71 (top 10 among types), with tanks like Wailord (HP 302).
- Fishing Mechanics: Leveling your fishing skill unlocks rare species. For example, Dratini requires a Level.
Complete List of All Fish Pokémon [36 Fish Pokémon Characters]
Below is the definitive table of all 36 fish Pokémon, including types, abilities, weaknesses, generations, and visual references.
Magikarp
| Detail | Information |
|---|---|
| Pokémon Name | Magikarp |
| Type(s) | Water |
| Abilities | Swift Swim / Rattled (Hidden) |
| Weaknesses | Electric, Grass |
| Generation | I |
Magikarp is infamous for being weak, but its true power lies in its evolution, Gyarados. As a standalone, its Swift Swim ability can make it surprisingly fast in a rain team, allowing it to potentially use a quick setup move or even chip away with a desperation Tackle before evolving. Its Hidden Ability, Rattled, boosts its Speed when hit by a Dark, Ghost, or Bug move, offering a small, niche opportunity for a speed boost against specific threats.
Gyarados
| Detail | Information |
|---|---|
| Pokémon Name | Gyarados |
| Type(s) | Water / Flying |
| Abilities | Intimidate / Moxie (Hidden) |
| Weaknesses | Electric (4x), Rock |
| Generation | I |
Gyarados is a truly fearsome Pokémon. Its Intimidate ability is fantastic for lowering the opponent’s Attack, making it an excellent switch-in or pivot in battles. With its Hidden Ability, Moxie, Gyarados becomes an incredible snowballing threat; its Attack stat increases every time it knocks out an opposing Pokémon. This allows it to sweep through weakened teams. Furthermore, its Mega Evolution (Water/Dark) gains the Mold Breaker ability, letting it ignore abilities like Levitate and making it even more dominant.
Goldeen
| Detail | Information |
|---|---|
| Pokémon Name | Goldeen |
| Type(s) | Water |
| Abilities | Swift Swim / Water Veil / Lightning Rod (Hidden) |
| Weaknesses | Electric, Grass |
| Generation | I |
While not a top-tier combatant, Goldeen’s Swift Swim can make it surprisingly quick in rain, allowing it to potentially outspeed and hit opponents before they react. Its Hidden Ability, Lightning Rod, can be an interesting option in Double Battles, drawing in Electric-type attacks and boosting Goldeen’s Special Attack. This allows it to protect an ally that might be weak to Electric moves, though its low base stats still limit its overall impact.
Seaking
| Detail | Information |
|---|---|
| Pokémon Name | Seaking |
| Type(s) | Water |
| Abilities | Swift Swim / Water Veil / Lightning Rod (Hidden) |
| Weaknesses | Electric, Grass |
| Generation | I |
Seaking, much like Goldeen, can leverage Swift Swim to become quite fast under rain. Its unique hidden battle potential lies in its access to the one-hit knockout move Horn Drill. While incredibly unreliable due to its low accuracy, pairing it with a setup move like Agility or through various accuracy-boosting strategies can make it a very niche, but potentially game-ending, surprise. Its Hidden Ability Lightning Rod also offers some utility in drawing Electric attacks in multi-battles.
Horsea
| Detail | Information |
|---|---|
| Pokémon Name | Horsea |
| Type(s) | Water |
| Abilities | Swift Swim / Sniper / Damp (Hidden) |
| Weaknesses | Electric, Grass |
| Generation | I |
Horsea’s true potential is largely unlocked through its evolutions. As a standalone, its Swift Swim ability provides a Speed boost in rain, which can be useful for early-game sweeps in certain formats. Its Sniper ability (shared with its evolution, Seadra) makes critical hits deal more damage, which can be fun to experiment with, but its low base stats mean it’s primarily a stepping stone to the more powerful Kingdra.
Seadra
| Detail | Information |
|---|---|
| Pokémon Name | Seadra |
| Type(s) | Water |
| Abilities | Poison Point / Sniper / Damp (Hidden) |
| Weaknesses | Electric, Grass |
| Generation | I |
Seadra boasts decent Special Attack for a middle-stage evolution. Its Sniper ability can make its critical hits devastating, especially when combined with high-critical-hit ratio moves like Focus Energy, turning it into a glass cannon. While it doesn’t have the ultimate power of Kingdra, it can be a surprisingly effective special attacker in lower-tier battles, especially if it manages to land those critical hits consistently.
Kingdra
| Detail | Information |
|---|---|
| Pokémon Name | Kingdra |
| Type(s) | Water / Dragon |
| Abilities | Swift Swim / Sniper / Damp (Hidden) |
| Weaknesses | Dragon, Fairy |
| Generation | II |
Kingdra is a formidable special attacker, particularly when its Swift Swim ability is activated in a rain team, effectively doubling its Speed. This allows it to outspeed and often one-shot many opponents. Its excellent Water/Dragon typing provides strong offensive coverage with few common resistances and only two weaknesses (Dragon and Fairy), making it a powerful late-game cleaner or a dangerous offensive pivot in competitive play.
Chinchou
| Detail | Information |
|---|---|
| Pokémon Name | Chinchou |
| Type(s) | Water / Electric |
| Abilities | Volt Absorb / Illuminate / Water Absorb (Hidden) |
| Weaknesses | Grass, Ground |
| Generation | II |
Chinchou’s unique Water/Electric typing gives it a useful set of resistances and immunities, especially with its abilities. Its Hidden Ability, Water Absorb, grants it immunity to Water-type attacks and heals its HP, making it a great switch-in against common Water-type threats. Volt Absorb provides a similar benefit against Electric attacks. While not a strong attacker, its ability to absorb hits and provide support makes it a niche but effective utility Pokémon.
Lanturn
| Detail | Information |
|---|---|
| Pokémon Name | Lanturn |
| Type(s) | Water / Electric |
| Abilities | Volt Absorb / Illuminate / Water Absorb (Hidden) |
| Weaknesses | Grass, Ground |
| Generation | II |
Lanturn excels as a bulky special wall and pivot. Its signature ability, Volt Absorb, grants it a crucial immunity to Electric-type attacks and restores its HP, making it an excellent counter to many Electric attackers. With Water Absorb (its Hidden Ability), it gains a second immunity to Water attacks, making it incredibly difficult to take down with special hits. It can dish out damage with STAB Hydro Pump and Thunderbolt or provide support with moves like Thunder Wave and Heal Pulse.
Qwilfish
| Detail | Information |
|---|---|
| Pokémon Name | Qwilfish |
| Type(s) | Water / Poison |
| Abilities | Poison Point / Swift Swim / Intimidate (Hidden) |
| Weaknesses | Electric, Ground, Psychic |
| Generation | II |
Qwilfish’s most significant hidden battle potential comes from its Hidden Ability, Intimidate, which lowers the opponent’s Attack stat upon entry. This makes it a surprisingly effective physical wall and pivot, capable of switching into dangerous physical attackers and reducing their damage output. It also has access to valuable entry hazards like Spikes and Toxic Spikes, allowing it to support its team by wearing down opponents.
Remoraid
| Detail | Information |
|---|---|
| Pokémon Name | Remoraid |
| Type(s) | Water |
| Abilities | Hustle / Sniper / Moody (Hidden) |
| Weaknesses | Electric, Grass |
| Generation | II |
Remoraid is primarily a pre-evolution, but its Hidden Ability, Moody, offers a chaotic yet potentially game-breaking hidden potential. Moody randomly boosts one of its stats by two stages while lowering another by one each turn. If you get lucky with the stat boosts, Remoraid can become surprisingly powerful, though its low base stats and the unpredictable nature of Moody make this a high-risk, high-reward strategy.
Octillery
| Detail | Information |
|---|---|
| Pokémon Name | Octillery |
| Type(s) | Water |
| Abilities | Suction Cups / Sniper / Moody (Hidden) |
| Weaknesses | Electric, Grass |
| Generation | II |
Octillery is a fantastic special attacker with an incredibly wide movepool, including powerful coverage options like Flamethrower, Ice Beam, and Energy Ball, making it highly versatile. Its Sniper ability boosts critical hit damage, making it a threatening choice if it can land those hits. However, its most interesting hidden potential comes from its Hidden Ability, Moody, which can randomly boost its stats, turning it into an unpredictable but potentially devastating late-game sweeper if it accumulates enough favorable stat changes.
Barboach
| Detail | Information |
|---|---|
| Pokémon Name | Barboach |
| Type(s) | Water / Ground |
| Abilities | Oblivious / Anticipation / Hydration (Hidden) |
| Weaknesses | Grass (4x) |
| Generation | III |
Barboach is mainly a stepping stone to the more robust Whiscash. However, its Hidden Ability, Hydration, gives it a niche role: it heals status conditions like poison or paralysis when it’s raining. This can be surprisingly useful in specific rain-focused team compositions, allowing Barboach to act as a pivot or support Pokémon that won’t be bogged down by status.
Whiscash
| Detail | Information |
|---|---|
| Pokémon Name | Whiscash |
| Type(s) | Water / Ground |
| Abilities | Oblivious / Anticipation / Hydration (Hidden) |
| Weaknesses | Grass (4x) |
| Generation | III |
Whiscash’s unique Water/Ground typing grants it only one weakness (a quadruple weakness to Grass), which makes it defensively solid against most other types. Its hidden potential lies in its access to Dragon Dance, a rare boosting move for its typing. If given a chance to set up a few Dragon Dances, Whiscash can become a surprising physical sweeper, overcoming its somewhat average offensive stats to deliver powerful blows.
Feebas
| Detail | Information |
|---|---|
| Pokémon Name | Feebas |
| Type(s) | Water |
| Abilities | Swift Swim / Oblivious / Adaptability (Hidden) |
| Weaknesses | Electric, Grass |
| Generation | III |
Feebas is notoriously weak, but its hidden battle potential is entirely tied to its powerful evolution, Milotic. What makes it particularly interesting is its Hidden Ability, Adaptability. While Feebas itself won’t be sweeping anything, a fully evolved Milotic with Adaptability gains a massive boost to its Water-type moves, turning it into a formidable special attacker that hits much harder than expected.
Milotic
| Detail | Information |
|---|---|
| Pokémon Name | Milotic |
| Type(s) | Water |
| Abilities | Marvel Scale / Competitive / Cute Charm (Hidden) |
| Weaknesses | Electric, Grass |
| Generation | III |
Milotic is an exceptional special wall with impressive HP and Special Defense. Its primary ability, Marvel Scale, boosts its Defense significantly when it’s afflicted by a status condition, making it incredibly tanky. Its Hidden Ability, Competitive, is a game-changer: it sharply raises Milotic’s Special Attack by two stages whenever its stats are lowered. This makes it an ideal counter to Pokémon that use abilities like Intimidate or moves that debuff stats, turning a defensive threat into a surprising offensive powerhouse.
Relicanth
| Detail | Information |
|---|---|
| Pokémon Name | Relicanth |
| Type(s) | Water / Rock |
| Abilities | Swift Swim / Rock Head / Sturdy (Hidden) |
| Weaknesses | Electric, Fighting, Grass, Ground |
| Generation | III |
Relicanth’s unique Water/Rock typing gives it access to powerful STAB moves like Head Smash. Its Rock Head ability prevents it from taking recoil damage from such powerful moves, allowing it to hit incredibly hard without consequence. With Swift Swim, it can double its speed in rain, becoming a surprisingly fast and devastating physical attacker that can punch through many defenses, making it a niche but dangerous threat.
Luvdisc
| Detail | Information |
|---|---|
| Pokémon Name | Luvdisc |
| Type(s) | Water |
| Abilities | Swift Swim / Hydration (Hidden) |
| Weaknesses | Electric, Grass |
| Generation | III |
Luvdisc is known for its low stats, making its competitive viability very limited. However, its Swift Swim ability can give it a speed boost in rain, allowing it to potentially outspeed and inflict status conditions with moves like Attract or Sweet Kiss, or even use a quick U-turn. Its Hidden Ability, Hydration, allows it to heal status conditions in rain, offering a small defensive utility, but overall, its low stats hinder any significant battle potential.
Finneon
| Detail | Information |
|---|---|
| Pokémon Name | Finneon |
| Type(s) | Water |
| Abilities | Swift Swim / Storm Drain / Water Veil (Hidden) |
| Weaknesses | Electric, Grass |
| Generation | IV |
Finneon is primarily a pre-evolution, but its Hidden Ability, Storm Drain, can be highly strategic in Double Battles. Storm Drain draws in all Water-type attacks aimed at any Pokémon on the field and boosts Finneon’s Special Attack. This makes it a great partner for Pokémon weak to Water, effectively giving them an immunity while simultaneously boosting Finneon’s own power before it evolves.
Lumineon
| Detail | Information |
|---|---|
| Pokémon Name | Lumineon |
| Type(s) | Water |
| Abilities | Swift Swim / Storm Drain / Water Veil (Hidden) |
| Weaknesses | Electric, Grass |
| Generation | IV |
Lumineon’s Storm Drain ability is its key to hidden battle potential. In Double Battles, it can redirect all Water-type attacks to itself, absorbing them and boosting its own Special Attack by one stage. This makes it an excellent ally for Pokémon that are weak to Water. With Swift Swim, it also gains a significant Speed boost in rain, allowing it to function as a fast pivot with U-turn or a special attacker under the right conditions.
Basculin (Red-Striped)
| Detail | Information |
|---|---|
| Pokémon Name | Basculin (Red-Striped) |
| Type(s) | Water |
| Abilities | Reckless / Adaptability (Hidden) |
| Weaknesses | Electric, Grass |
| Generation | V |
The Red-Striped Basculin’s Reckless ability boosts the power of moves that cause recoil, such as Head Smash (via TM/TR) or Wave Crash (a newer move), allowing it to hit incredibly hard, albeit at a cost to its own HP. With high Speed, it can be a surprising glass cannon that can punch holes in unprepared teams. Its Hidden Ability, Adaptability, makes its STAB Water moves even more devastating.

Basculin (Blue-Striped)
| Detail | Information |
|---|---|
| Pokémon Name | Basculin (Blue-Striped) |
| Type(s) | Water |
| Abilities | Adaptability / Rock Head (Hidden) |
| Weaknesses | Electric, Grass |
| Generation | V |
The Blue-Striped Basculin shines with its Adaptability ability, which significantly boosts the power of its Water-type moves (like Waterfall or Aqua Jet) from 1.5x to 2x. This, combined with its high Speed, makes it a potent physical attacker that can outspeed and deal immense damage to many opponents. Its Hidden Ability, Rock Head, is a powerful alternative, preventing recoil damage from moves like Head Smash.
Basculin (White-Striped)
| Detail | Information |
|---|---|
| Pokémon Name | Basculin (White-Striped) |
| Type(s) | Water |
| Abilities | Swift Swim / Mold Breaker (Hidden) |
| Weaknesses | Electric, Grass |
| Generation | V |
The White-Striped Basculin is often seen as a direct precursor to Basculegion. Its Hidden Ability, Mold Breaker, is incredibly valuable as it allows Basculin to ignore the abilities of opposing Pokémon when attacking. This means it can hit through troublesome abilities like Levitate (affecting Ground moves), Sturdy, or Wonder Guard, making it a surprisingly versatile offensive threat. Swift Swim also makes it deadly in rain.
Alomomola
| Detail | Information |
|---|---|
| Pokémon Name | Alomomola |
| Type(s) | Water |
| Abilities | Healer / Hydration / Regenerator (Hidden) |
| Weaknesses | Electric, Grass |
| Generation | V |
Alomomola is a premier special wall and a fantastic “pivot” thanks to its incredible bulk and, most importantly, its Hidden Ability, Regenerator. This ability restores one-third of its maximum HP whenever it switches out, making it extremely difficult to wear down. It can reliably use moves like Wish to heal itself or its teammates, and Protect to scout opponent’s moves, making it an incredibly resilient and supportive Pokémon.
Stunfisk
| Detail | Information |
|---|---|
| Pokémon Name | Stunfisk |
| Type(s) | Ground / Electric |
| Abilities | Static / Limber / Sand Veil (Hidden) |
| Weaknesses | Grass (4x), Water, Ice |
| Generation | V |
Despite its goofy appearance, Stunfisk’s unique Ground/Electric typing gives it a surprising set of resistances and an immunity to Electric moves. Its Static ability can paralyze physical attackers. Its hidden potential lies in its unexpected bulk and ability to set up entry hazards like Stealth Rock. It can function as a defensive pivot, absorbing hits and disrupting opponents with status conditions, often catching players off guard.

Stunfisk (Galarian)
| Detail | Information |
|---|---|
| Pokémon Name | Stunfisk (Galarian) |
| Type(s) | Ground / Steel |
| Abilities | Mimicry |
| Weaknesses | Fire (4x), Water, Fighting, Ground |
| Generation | VIII |
Galarian Stunfisk has a truly unique ability in Mimicry. This ability changes its type to match the current terrain. For example, in Electric Terrain, it becomes Electric/Steel. This allows for incredible defensive and offensive flexibility, as it can gain resistances or STAB boosts depending on the battlefield conditions. While it requires specific team synergy to fully utilize, a well-played Galarian Stunfisk can be a highly unpredictable and frustrating opponent.
Skrelp
| Detail | Information |
|---|---|
| Pokémon Name | Skrelp |
| Type(s) | Poison / Water |
| Abilities | Poison Touch / Poison Point / Adaptability (Hidden) |
| Weaknesses | Electric, Ground, Psychic |
| Generation | VI |
Skrelp’s hidden battle potential, much like Feebas, truly shines in its evolution, Dragalge. Its Hidden Ability, Adaptability, is key. While Skrelp itself is weak, a Dragalge with Adaptability gains a massive boost to its Poison and Dragon-type moves, transforming it from a niche pick into a surprisingly powerful special attacker that can inflict serious damage on a wide range of foes.
Dragalge
| Detail | Information |
|---|---|
| Pokémon Name | Dragalge |
| Type(s) | Poison / Dragon |
| Abilities | Poison Touch / Poison Point / Adaptability (Hidden) |
| Weaknesses | Dragon, Ground, Ice, Psychic |
| Generation | VI |
Dragalge boasts a fantastic defensive typing in Poison/Dragon, giving it resistances to many common attacking types. Its hidden potential is fully realized with its Hidden Ability, Adaptability. This ability dramatically increases the power of its Poison and Dragon-type STAB moves, allowing Dragalge to hit surprisingly hard on the special side despite its average Special Attack. It can serve as a bulky special attacker or a defensive pivot that can punish switches.
Wishiwashi (Solo Form)
| Detail | Information |
|---|---|
| Pokémon Name | Wishiwashi (Solo Form) |
| Type(s) | Water |
| Abilities | Schooling (changes to School Form) |
| Weaknesses | Electric, Grass |
| Generation | VII |
Wishiwashi in its Solo Form is famously weak, designed to be almost useless. Its entire hidden battle potential lies in its unique ability, Schooling. When Wishiwashi is above 25% of its maximum HP at the end of a turn, its Schooling ability activates, transforming it into its powerful School Form. The strategic challenge is maintaining its HP above this threshold to keep its formidable form.
Wishiwashi (School Form)
| Detail | Information |
|---|---|
| Pokémon Name | Wishiwashi (School Form) |
| Type(s) | Water |
| Abilities | Schooling (changes to Solo Form) |
| Weaknesses | Electric, Grass |
| Generation | VII |
In its School Form, Wishiwashi transforms into one of the most statistically powerful Pokémon in the game, boasting incredibly high Attack, Special Attack, and defensive stats. This form allows it to become a legitimate force, capable of tanking hits and dishing out massive damage. Its hidden battle potential lies in its overwhelming stat distribution, making it a terrifying presence on the field as long as its HP stays above the 25% threshold to maintain this powerful form.
Bruxish
| Detail | Information |
|---|---|
| Pokémon Name | Bruxish |
| Type(s) | Water / Psychic |
| Abilities | Dazzling / Strong Jaw / Wonder Skin (Hidden) |
| Weaknesses | Bug, Dark, Electric, Grass, Ghost |
| Generation | VII |
Bruxish possesses two excellent abilities for competitive play. Dazzling prevents opposing Pokémon from using priority moves, which can completely shut down common offensive strategies. Its Strong Jaw ability boosts the power of all biting moves (like Psychic Fangs and Crunch) by 50%, turning Bruxish into a potent physical attacker. This makes it capable of hitting surprisingly hard and breaking through various defensive setups.
Arrokuda
| Detail | Information |
|---|---|
| Pokémon Name | Arrokuda |
| Type(s) | Water |
| Abilities | Swift Swim / Propeller Tail (Hidden) |
| Weaknesses | Electric, Grass |
| Generation | VIII |
Arrokuda’s primary potential lies in its evolution, Barraskewda. However, its Hidden Ability, Propeller Tail, offers a unique utility: it prevents its moves from being affected by opposing abilities that redirect attacks (like Storm Drain or Lightning Rod). This ensures its attacks hit their intended target, which can be useful for tactical plays in Double Battles before evolving.
Barraskewda
| Detail | Information |
|---|---|
| Pokémon Name | Barraskewda |
| Type(s) | Water |
| Abilities | Swift Swim / Propeller Tail (Hidden) |
| Weaknesses | Electric, Grass |
| Generation | VIII |
Barraskewda is an incredibly fast physical attacker, especially when its Swift Swim ability is activated in rain, making it one of the fastest Pokémon in the game. This allows it to outspeed and often one-shot many opponents with powerful Water-type moves. Its Hidden Ability, Propeller Tail, ensures its attacks bypass redirection abilities, allowing it to strike critical targets reliably, making it a pure offensive force.
Basculin (Hisuian)
| Detail | Information |
|---|---|
| Pokémon Name | Basculin (Hisuian) |
| Type(s) | Water |
| Abilities | Reckless / Adaptability / Mold Breaker (Hidden) |
| Weaknesses | Electric, Grass |
| Generation | VIII |
Hisuian Basculin is the pre-evolution of Basculegion, and its chosen ability directly impacts its evolutionary potential. With Reckless, its recoil moves like Wave Crash become incredibly powerful, setting it up as a formidable physical attacker. Adaptability (its common ability) significantly boosts the power of its Water STAB moves, making it a consistently strong offensive threat. Its Hidden Ability, Mold Breaker, allows it to bypass defensive abilities, making it an excellent choice for breaking through tricky opponents before evolving.
Basculegion
| Detail | Information |
|---|---|
| Pokémon Name | Basculegion |
| Type(s) | Water / Ghost |
| Abilities | Swift Swim / Adaptability / Mold Breaker (Hidden) |
| Weaknesses | Dark, Electric, Ghost, Grass |
| Generation | VIII |
Basculegion is a unique and powerful physical attacker with its Water/Ghost typing. Its signature potential lies in its abilities: Swift Swim makes it incredibly fast in rain, while Adaptability (its common ability) boosts the power of its STAB Water and Ghost moves to an insane degree. If it has Mold Breaker (its Hidden Ability), it can bypass troublesome abilities like Wonder Guard or Levitate, making it a versatile and often overwhelming offensive threat.
Finizen
| Detail | Information |
|---|---|
| Pokémon Name | Finizen |
| Type(s) | Water |
| Abilities | Water Veil |
| Weaknesses | Electric, Grass |
| Generation | IX |
Finizen’s true hidden battle potential is entirely contained within its unique evolution method and its incredibly powerful evolved form, Palafin. As a standalone, Finizen is quite weak, primarily serving as a pre-evolution. Its Water Veil ability prevents it from being burned, which is a minor defensive utility, but its stats limit any significant impact until it undergoes its special evolution into Palafin’s Hero Form.
Palafin (Zero Form)
| Detail | Information |
|---|---|
| Pokémon Name | Palafin (Zero Form) |
| Type(s) | Water |
| Abilities | Zero to Hero |
| Weaknesses | Electric, Grass |
| Generation | IX |
Palafin’s Zero Form is deliberately designed to be underwhelming. Its entire hidden battle potential is built around its unique ability, Zero to Hero. This ability transforms Palafin into its vastly more powerful Hero Form when it is switched out of battle and then switched back in. This requires strategic play, essentially dedicating a turn to switching, but the payoff is an almost unparalleled offensive force.
Palafin (Hero Form)
| Detail | Information |
|---|---|
| Pokémon Name | Palafin (Hero Form) |
| Type(s) | Water |
| Abilities | Zero to Hero |
| Weaknesses | Electric, Grass |
| Generation | IX |
Once Palafin transforms into its Hero Form, it gains an astronomical boost to its Attack, Defense, and Special Defense, making it one of the most dominant physical attackers in the game. Its hidden battle potential lies in its ability to single-handedly sweep teams after a successful “flip turn” (switching out and back in). It becomes incredibly difficult to stop, hitting extremely hard with powerful Water-type moves and possessing surprisingly good bulk to withstand hits.
Tatsugiri
| Detail | Information |
|---|---|
| Pokémon Name | Tatsugiri |
| Type(s) | Dragon / Water |
| Abilities | Commander / Storm Drain (Hidden) |
| Weaknesses | Dragon, Fairy |
| Generation | IX |
Tatsugiri’s hidden battle potential is almost entirely dependent on its unique interaction with Dondozo in Double Battles. Its Commander ability (when paired with Dondozo) boosts all of Dondozo’s stats by two stages, turning Dondozo into an unstoppable force while Tatsugiri hides in its mouth. As a standalone, its Hidden Ability, Storm Drain, can draw in Water-type attacks, boosting its Special Attack, making it a niche special attacker or a valuable ally against Water types.
