Rematch

---

A rematch or re-battle (Japanese: 再戦 rematch) is a second or subsequent battle against a Trainer or Pokémon.

In the core series games, it is mandatory for the player to defeat certain Trainers to advance within the game. Technically, if the player is defeated, they are given the chance to battle this opponent again until defeated (barring exceptional circumstances), but this isn't considered a rematch.

Most of the time, however, if a Trainer is defeated, that Trainer will not be available for a rematch until certain conditions have been met. When Trainers usually agree to rematch, their Pokémon will have become stronger (level up or evolution), or they would already have acquired more Pokémon (sometimes from another region, once the player has obtained the National Pokédex).

Types of rematch

Regular Trainers

From Generation II onward, with the exception of Pokémon Black and White and X and Y, some regular Trainers found along normal routes and caves can be challenged for a rematch.

In Pokémon Gold, Silver, and Crystal, the player can exchange Pokégear phone numbers with specific Trainers, allowing them to contact the player for a rematch. Note that Trainers have to be rebattled as soon as possible, otherwise the chance to do so will disappear.

In Pokémon HeartGold and SoulSilver, trainer rematches through the Pokégear cannot be initiated until the following requirements are met:

• The player has collected seven Badges
• Team Rocket has been defeated at the Radio Tower in Goldenrod City
• The player is not currently in the same route or location as the trainer
• The player calls the trainer during the day of the week and time of day the trainer is open to rematch (trainers may call the player at random to rematch regardless of their rematch window)

Unlike Gold, Silver, and Crystal, trainers can be rebattled multiple times per day within their rematch window.

In Pokémon Gold, Silver, and Crystal, the number of difficulty levels and triggers are defined individually for each Trainer. Certain rematches are available only in Gold and Silver, while others are only in Crystal. The potential of a trainer calling for a rematch resets daily, but the following events are additional triggers for new rematches:

• Reaching a new city/town in Johto, starting with Goldenrod City
• Reaching the Lake of Rage
• Defeating Team Rocket at Mahogany Town or Goldenrod City
• Becoming Champion
• Returning the Machine Part to the Kanto Power Plant

Additionally, in Gold and Silver, the player will battle the strongest team available, but in Crystal, each team has to be battled in order (including fighting the initial team again).

In Pokémon HeartGold and SoulSilver, the Trainers' teams change three different times throughout the games' progression:

• Firstly after the player has obtained seven Badges and Team Rocket has been defeated at the Radio Tower in Goldenrod City
• Secondly after the player has entered the Hall of Fame for the first time
• Thirdly after the player has obtained all 16 Badges

In Pokémon Ruby, Sapphire, and Emerald, the PokéNav's Trainer's Eyes or Match Call has similar functions to the Pokégear, keeping track of Trainers who eventually want to re-battle the player. Regular Trainers are eligible for rematches after obtaining the Balance Badge; once it is obtained, if the player is on a map with eligible Trainers, each Trainer on the map has a separate 31% chance to demand a rematch every 255 steps.

In Pokémon Omega Ruby and Alpha Sapphire, the Trainer's Eye function returns, and Trainers are ready for a rematch more frequently than in Generation III; in these games, the Trainers' teams improve as the player progresses through the game, and are at their strongest after the player has entered the Hall of Fame.

Red uses the Vs. Seeker on Route 25. Three Trainers wish to have a rematch.

In Pokémon FireRed and LeafGreen, Pokémon Diamond, Pearl, and Platinum, and Pokémon Brilliant Diamond and Shining Pearl, while outdoors, the player can use the Vs. Seeker to randomly make nearby Trainers ready for a rematch. Certain Trainers have stronger teams, depending on how far the player is through the game, as long as they have defeated that Trainer's previous party. New Vs. Seeker parties are unlocked at the following events:

• Obtaining the Vs. Seeker
• Arriving in Celadon City^FRLG/defeating Fantina^DP/arriving in Celestic Town^Pt
• Arriving in Fuchsia City^FRLG/capturing or defeating the cover Legendary Pokémon^DPPt
• Entering the Hall of Fame
• Delivering the Sapphire to Celio^FRLG/capturing or defeating Heatran at Stark Mountain^DPPt.

In Pokémon Diamond, Pearl, and Platinum, certain Trainers can be challenged daily at the Seven Stars Restaurant. In Pokémon Diamond and Pearl, the player can battle one Trainer per day at Jubilife TV, with the Trainer that appears varying with the day of the week. In Pokémon Platinum, players can challenge several Trainers that appear in different Pokémon Centers once per day each, as well as repeatedly battle the Maids in the 5-Maid Knockout Exact-Turn Attack Challenge in the Pokémon Mansion.

In Pokémon Black and White and Pokémon Black 2 and White 2, Trainers in the Big Stadium and Small Court of Nimbasa City and the Royal Unova can be rematched daily. In Pokémon Black 2 and White 2, as the player progresses through the game, the Trainers' Pokémon are battled at higher levels, and will be at their strongest after the player has entered the Hall of Fame. Some Trainers may replace their Pokémon. Pokémon Breeders in Black 2 and White 2 will re-challenge the player upon sight (as long as the player has left the area since their last battle), even if the player had previously defeated them; however, their teams remain the same during each battle.

In Pokémon X and Y, Trainers in the Battle Chateau can be battled each time that Trainer has entered the Battle Chateau. Only those whose rank is the same as or lower than the player's will appear. The player can purchase writs to have an effect on three different factors (party levels, prize money, and Trainer arrival rate) for the remainder of that day, although issued writs can be swapped out if the new one has the same type of effect.

In Pokémon Sun, Moon, Ultra Sun, and Ultra Moon, certain Trainers can be challenged daily^SM/repeatedly^USUM at the Battle Buffet at Hau'oli City's Shopping District.

In Pokémon Sword and Shield, Pokémon Breeder Chloe can be rematched whenever she is found in the Wild Area, with teams differing based on if the player received the Fire Badge and if they enter the Hall of Fame. The Café Masters in the Battle Cafés throughout Galar can also be challenged daily.

In Pokémon Colosseum and Pokémon XD, there are certain areas that allow for multiple rematches, most notably in Pyrite Town's Duel Square. Other locations such as Agate Village and The Under Subway allow for rematches only after getting past a certain point in the game.

Rival

Since Generation I, the player's rivals play key roles within the game, occasionally giving hints, helping out or even challenging the player to a rematch. In every game, at least one of the player's rivals can be repeatedly rematched after entering the Hall of Fame of that region.

The following table shows where and when the player's rivals can be challenged for subsequent rematches:

Gym Leaders

Gym Leader rematches were first introduced in Pokémon Emerald. They are featured in all subsequent core series games with Gym Leaders, except for Pokémon Diamond & Pearl, Black & White, and Omega Ruby & Alpha Sapphire.

Pokémon Emerald

After the player has entered the Hall of Fame for the first time, the player can rematch Gym Leaders. There is a 31% chance for a Gym Leader rematch to become available after every 60th wild encounter, every 20th Trainer battle, and every 20th Battle Frontier battle.

Each Gym Leader has four teams, ordered from lowest levels to highest levels, and they will use each team after the player defeats their previous team. All teams contain Pokémon outside the Hoenn Pokédex. The player will not be able to move on to any Gym Leader's second rematch until they have defeated all Gym Leaders' first rematch, the same holds true for the third and fourth rematches.

Wattson is not available for a rematch until the player has completed the New Mauville sidequest. Since all Gym Leaders need to be defeated in a rematch to unlock the next set of rematch teams, completing this sidequest is also a prerequisite for unlocking the second set of rematch teams.

Pokémon Platinum

Battleground (from left): Maylene, Volkner, the player, the Café owner

Main article: Battleground

In Pokémon Platinum, the Gym Leaders of Sinnoh, together with the player's previous Multi Battle partners, can be found in the Battleground. Up to four of these Trainers appear each day and they can be battled only once a day. The residing Trainers are generated upon entering the Battleground, potentially allowing for different Trainers after game resets.

Pokémon HeartGold and SoulSilver

The Fighting Dojo with all the Gym Leaders

Main article: Fighting Dojo/Generation IV

In Pokémon HeartGold and SoulSilver, the Gym Leaders of Kanto and Johto are found in the Fighting Dojo. However, unlike Platinum, the Leaders will not arrive at the Dojo until they have been called on for a rematch.

To re-battle a Gym Leader, the player has to first obtain the Gym Leader's number. Following that, the player can call the Gym Leader at any time, but the Gym Leader will only accept a rematch when their schedule is free. When a Gym Leader has accepted a rematch, they will stay in the Fighting Dojo until they are defeated. There is no limit to the number of times a Gym Leader can be rematched.

Pokémon Black 2 and White 2

Main article: Pokémon World Tournament

In Black 2 and White 2, Gym Leaders can be rematched in the Unova Leaders Tournament at the Pokémon World Tournament.

Pokémon X and Y

Main article: Battle Chateau

In X and Y, the Gym Leaders of Kalos can be rematched at the Battle Chateau once the player has reached the rank of Marquis or Marchioness. The Gym Leaders use two of their Pokémon, who start at level 40. After the player has entered the Hall of Fame, the base level of their team is changed to level 50, and the Pokémon for some of the Gym Leaders have been replaced.

Unlike in previous games, the Elite Four and Champion of Kalos do not receive higher level teams when rematched at the Pokémon League. Instead, they can also be encountered at the Chateau. The Elite Four can be rematched when the player reaches the rank of Duke or Duchess. They use three Pokémon at the base level of 55. Finally, Champion Diantha can be rematched when the player reaches the highest rank, Grand Duke or Grand Duchess, respectively. She uses four Pokémon, including her Mega Gardevoir, at the base level of 60.

Like other Trainers at the Battle Chateau, issuing certain writs can be used to adjust the levels of the teams used there by Gym Leaders, the Elite Four, and Diantha, as well as giving them the chance to appear more frequently.

Pokémon: Let's Go, Pikachu! and Let's Go, Eevee!

In Pokémon: Let's Go, Pikachu! and Let's Go, Eevee!, after the player has entered the Hall of Fame, each Gym Leader of Kanto can be rematched at their respective Gym once per day. At the Viridian Gym, Blue is battled instead of Giovanni. In addition, the Pokémon League can also be challenged again, with all Elite Four members possessing a Kanto Pokémon's Alolan form.

Pokémon Brilliant Diamond and Shining Pearl

In Pokémon Brilliant Diamond and Shining Pearl, each Gym Leader of Sinnoh can be challenged to a rematch at their respective Gym once per day after the National Pokédex has been obtained.

Pokémon Scarlet and Violet

In Scarlet and Violet, the Gym Leaders of Paldea are rematched once each as part of the post-game. Nemona suggests hosting a battle tournament at Naranja^S/Uva Academy^V to celebrate the player's new Champion status, requesting for Geeta to take part in it as well as she is the chairwoman of the academy's school board. While Geeta says she's busy with her duties as the Pokémon League chairwoman, she agrees to take part if the player takes her place at inspecting all the Gym Leaders to see if they're still worthy of keeping their positions. Unlike previous games, these rematches are not repeatable.

In The Indigo Disk, Gym Leaders can be invited to Blueberry Academy's League Club Room as special coaches for 200 BP, where they can be rematched any number of times. In addition, the first time they are defeated, they will reward the player with an item, and after their third unique interaction, they will trade a specific Pokémon to the player.

Pokémon League

The Pokémon League can be rematched in all core series games featuring one except Pokémon Sword and Shield and Pokémon Scarlet and Violet. Starting in Pokémon FireRed and LeafGreen, most rematches against the Elite Four and Champion feature teams at higher levels, sometimes with different Pokémon, moves, stats, or held items.

In Generation I, they are the only Trainers that can be rematched.

Generation III

Ruby, Sapphire, and Emerald

The Pokémon League can be rematched, however the teams used are identical to prior completions.

FireRed and LeafGreen

The Indigo Plateau will start using higher-level Pokémon once the player has completed the Sevii Islands post-game quest.

Generation IV

Diamond and Pearl

The Pokémon League can be rematched, however the teams used are identical to prior completions.

Platinum

The Pokémon League uses higher-level Pokémon after the player completes the Stark Mountain sidequest.

HeartGold and SoulSilver

The Indigo Plateau will start using higher-level Pokémon once the player has earned all 16 Badges.

Generation V

Black, White, Black 2, and White 2

The Pokémon League uses higher-level Pokémon after the player defeats them the first time.

Generation VI

X and Y

The Pokémon League can be rematched, however the teams used are identical to prior completions.

Omega Ruby and Alpha Sapphire

The Pokémon League will start using higher-level Pokémon once the player has completed the Delta Episode.

Generation VII

Sun, Moon, Ultra Sun, and Ultra Moon

The Pokémon League uses higher-level Pokémon after the player defeats them the first time.

Let's Go, Pikachu! and Let's Go, Eevee!

The Indigo Plateau will start using higher-level Pokémon, different species, as well as Alolan forms and Mega Evolved versions of certain species, after the player has become Champion.

Generation VIII

Pokémon Brilliant Diamond and Shining Pearl

The Pokémon League has two sets of rematches.

The first set of rematch teams are used after the player has defeated the Pokémon League once and obtained the National Pokédex. These teams are based on the post-Stark Mountain teams the Elite Four and the Champion use in Pokémon Platinum.

The second set of rematch teams are used after the player catches Heatran at Stark Mountain and has defeated the first set of rematch teams at least once.

Generation IX

Pokémon Scarlet and Violet

While the player is normally unable to rematch the Elite Four, both Hassel and Geeta will compete in the Academy Ace Tournament as random opponents.

Furthermore, in The Indigo Disk, much like the Gym Leaders, the Paldea Elite Four and Geeta can be invited to Blueberry Academy's League Club Room as special coaches for 200 BP and can be rematched any number of times. Larry does not require any prerequisites to be invited; for Rika and Poppy to be invited into the League Club Room, the player must have traded with five special coaches; Hassel requires trades with three special coaches, along with completing his bonding event; Geeta requires trades with eight special coaches. Like the Gym Leaders, they will give a specific item upon their first defeat, and trade a specific Pokémon upon their third unique interaction.

The BB League Elite Four can also be rematched by talking to them in League Club Room. They do not require an invite, but only three can be present at a time and they can only be battled once per day.

Title Defense

Pokémon Sun, Moon Ultra Sun, and Ultra Moon

Main article: Pokémon League (Alola)/Title Defense

In Pokémon Sun, Moon, Ultra Sun, and Ultra Moon, the player, as the first Champion of Alola, has the opportunity to defend their title after completing their rematches against the Elite Four. In addition to their rivals, Hau and Gladion, challengers include Trial Captain Sophocles, island kahuna Hapu, former Team Skull Admin Plumeria, and the League's founder, Professor Kukui.

Pokémon Sword and Shield

In Pokémon Sword and Shield, after the player becomes Champion, they can defend their title in subsequent Champion tournaments in Wyndon Stadium. Players can invite a sitting Gym Leader, their rival Hop, former Leader Piers, or former Champion Leon to join the tournament before it starts. However, doing so does not guarantee that the invited Trainer will be battled by the player, as they can be defeated in rounds prior to reaching the player. All Gym Leaders featured in the player's game of choice can be challenged through this tournament, except for Opal, who retires her title to one of the player's rivals, Bede.

After the player has completed The Crown Tundra story, the Galarian Star Tournament is opened. It allows the player to rematch all the present and former Gym Leaders, Hop, Leon, Peony, Sordward, and Shielbert in Multi Battle tournaments.

Other special Trainers

Red

Once the player had defeated Red in Pokémon Gold, Silver, Crystal, HeartGold, and SoulSilver, he will reappear at Mt. Silver Cave every time the player enters the Hall of Fame.

Green

Once the player had defeated Green in Pokémon: Let's Go, Pikachu! and Let's Go, Eevee!, she will reappear in Cerulean City. The player can battle her once a day.

GAME FREAK

Introduced in Pokémon Black and White, Morimoto of GAME FREAK can be battled once a day GAME FREAK's in-game regional headquarters in Pokémon Black, White, Black 2, and White 2, Sun, Moon, Ultra Sun, Ultra Moon, Sword, Shield, Brilliant Diamond and Shining Pearl, usually after entering the region's respective Hall of Fame. In Black 2 and White 2, the player can also battle Nishino, and in Ultra Sun and Ultra Moon, the player battles Morimoto and Iwao in a Double Battle.

The player can also battle Morimoto in Pokémon: Let's Go, Pikachu! and Let's Go, Eevee!, but he is not rematchable in these games.

Mustard and Honey

In The Isle of Armor, after the player has defeated Mustard in the Battle Court, they can rematch him once a day upon request. Honey can also be battled daily after spending enough Watts to upgrade the Master Dojo.

Peony

In The Crown Tundra, after the "They Came From The Ultra Beyond!" adventure is started, the player can battle Peony in the Max Lair once a day.

Academy staff

In The Indigo Disk, staff members from Naranja Academy^S/Uva Academy^V can be invited to Blueberry Academy's League Club Room after trading with three special coaches, along with completing their respective bonding events, after which each of them can be rematched daily.

Arven and Penny

In The Hidden Treasure of Area Zero, the player can invite Arven and Penny to Blueberry Academy's League Club Room and rematched any number of times after completing the Mochi Mayhem epilogue.

Wild Pokémon from in-game events

Main article: List of wild Pokémon from in-game events

This section is incomplete. Please feel free to edit this section to add missing information and complete it. Reason: Are effort values awarded in mandatory captures? Do rematches also apply for wild Mythical Pokémon? Stakataka/Blacephalon in USUM: do they reappear if defeated?

In all games, being defeated by a Legendary Pokémon does not cause it to disappear. In all games in which roaming Pokémon exist, fleeing from them does not cause them to permanently disappear; the game simply behaves the same as if they were the ones to flee.

Prior to Pokémon FireRed and LeafGreen, fleeing from stationary Legendary Pokémon causes the Pokémon to permanently disappear.

In Pokémon FireRed, LeafGreen, and Emerald, if the player flees from a stationary Legendary Pokémon, it will reappear upon leaving and re-entering the room. The game informs the player that "The <Pokémon> flew away!". If the player defeats an event exclusive Legendary/Mythical Pokémon, it reappears after the player next enters the Hall of Fame.

In Pokémon Platinum, if the player defeats or flees from a stationary Legendary Pokémon, it reappears after the player next enters the Hall of Fame. If the player defeats a roaming Pokémon, it will reappear only after the player has re-triggered the event which caused it to start roaming; for example, the player must talk to Professor Oak to cause a Legendary bird to resume roaming. If the player flees from or defeats Origin Forme Giratina in the Distortion World, it will reappear in Turnback Cave in its Altered Forme, where it behaves in the same way as all other stationary Legendary Pokémon.

This was extended to all stationary Pokémon (red Gyarados, Sudowoodo, and Snorlax) in HeartGold and SoulSilver. If Suicune is defeated or fled from, Eusine will comment on this fact, and it will instead reappear at the Burned Tower, where it behaves in the same way as all other stationary Legendary Pokémon. If Ho-Oh^HG or Lugia^SS is defeated or fled from during the storyline, the Kimono Girls will comment on this fact before leaving; however, the Pokémon still behave like any other stationary Pokémon.

In Pokémon Black and White, Reshiram^B or Zekrom^W must be caught; defeating, fleeing from or losing to the Pokémon does not cause it to disappear, the battle yields no experience, and the story cannot be progressed until it is caught. However, if the player has a full party and PC, it is possible to progress without catching it, in which case it instead appears at Dragonspiral Tower after defeating Ghetsis, where it behaves in the same way as all other stationary Legendary Pokémon, except that it will still not give any experience points.

In Pokémon X and Y, Xerneas^X or Yveltal^Y must be caught; defeating, fleeing from or losing to it does not cause it to disappear, the battle yields no experience, and the story cannot be progressed until it is caught. The 31st box in the Pokémon Storage System does not become available until after the player catches it, so it is not possible to avoid the capture even if the player's party and PC are both full.

In Pokémon Omega Ruby and Alpha Sapphire, if the player defeats Groudon^OR or Kyogre^AS instead of catching them in the main story, they will reappear in the Cave of Origin after entering the Hall of Fame. During the Delta Episode, Rayquaza must be caught; defeating, fleeing from or losing to it does not cause it to disappear, the battle yields no experience, and the story cannot be progressed until it is caught. The 31st box in the Pokémon Storage System does not become available until after the player catches Rayquaza, so it is not possible to avoid the capture even if the player's party and PC are both full. If the player flees from or defeats Deoxys in during the Delta Episode, it will reappear at the Dragonhark altar atop the Sky Pillar after entering the Hall of Fame again, where it behaves in the same way as all other stationary Legendary Pokémon.

In Pokémon Sun and Moon, Solgaleo^S or Lunala^M must be caught; defeating, fleeing from or losing to it does not cause it to disappear, the battle yields no experience, and the story cannot be progressed until it is caught. The 31st box in the Pokémon Storage System does not become available until after the player catches the Legendary Pokémon. If the player defeats, flees from, or loses to Tapu Koko instead of catching it during the post-credits event, Lillie will comment on this fact, and Tapu Koko will immediately be available to battle again at the Ruins of Conflict. If the player defeats, flees from or loses to a roaming Ultra Beast or Necrozma, it will continue to reappear in the area until it is caught (the game reassures the player that it is still in the area).

In Pokémon Ultra Sun and Ultra Moon, Solgaleo^US or Lunala^UM must be caught for it to disappear; defeating, fleeing from or losing to it does not cause it to disappear and the battle yields no experience. The 31st box in the Pokémon Storage System does not become available until after the player catches the Legendary Pokémon.

In spin-off games

Pokémon Mystery Dungeon series

In the Pokémon Mystery Dungeon series, Legendary Pokémon that have been battled and are involved in the storyline must be fought again in order to be recruited.

Pokémon Ranger series

In the Pokémon Ranger series, the Drowsy Guy will allow the player to re-do a memorable capture. In Pokémon Ranger, he allows the player to re-capture the Legendary beasts, while in the sequel, he allows the player to re-capture Darkrai. In Pokémon Ranger: Guardian Signs, Nema allows the player to re-battle several Boss Pokémon on a model of Dolce Island via the use of her "Many Times Any Time Capture Machine".

Pokémon Trading Card Game series

In Pokémon Trading Card Game and Pokémon Trading Card Game 2: The Invasion of Team GR!, all duelists are available for rematches. However, in some cases, a duelist switches their deck permanently at some point. For instance, the rival character Ronald uses four decks in the first game: the first three decks are used in a single duel each, and then the fourth deck is used whenever the player challenges him for the Champion title at the Pokémon Dome. Similarly, in the second game, some Club Masters use a certain deck on their first duel, and then use a different deck in all subsequent duels.

Pokémon Play It! series

In Pokémon Play It! and Pokémon Play It! Version 2, there is no limit to the number of Trading Card Game matches against Julie.

In the anime

With the exception of the Orange League, Ash has had rematches with at least one Gym Leader, Frontier Brain, island kahuna, or World Coronation Series opponent in each leg of his journey. It is noted that the list does not list any match-up which could not be defined as a battle.

Trivia

• Giovanni is the only in-game Gym Leader that cannot be rematched an indefinite amount of times. However, he can be battled multiple times via an event at Tohjo Falls, if the player has multiple Celebi, as well as at the Pokémon World Tournament.
  • Koga, the other former Kanto Gym Leader, has been able to be rematched indefinitely since Generation II, where he was an Elite Four member, as well as in Pokémon: Let's Go, Pikachu! and Let's Go, Eevee!.
