This is a list of glitches in the Generation IV Pokémon games.

Some glitches are found on a separate page:

Pokémon Diamond, Pearl, Platinum, HeartGold, and SoulSilver

Corrupted save file cloning

Occasionally, when the save file gets corrupted, the Pokémon data is kept. When this happens, the game can still be saved, but the save file will be unable to be loaded. With the assistance of another handheld and another game, the Pokémon can be traded from the game with the corrupted save file. After the trade is completed, if the game is rebooted, the Pokémon traded from the corrupted save file will be in both games but the other traded Pokémon will be lost.

GTS morphing glitch

An example of the morphing glitch. This is not a Torterra, but a Mew morphed into one and nicknamed "TORTERRA"

There have been somewhat numerous reports of a glitch that happened in the GTS that causes a player's offered Pokémon to become "morphed". The Pokémon's sprite will change into that of a different Pokémon and the gender might be swapped as well. The game will also say it is the same species it used to be (e.g.: a morphed Heatran would still be recognized as such) and it will be holding a Seal Bag, an unused item. There is no confirmed way to reproduce this glitch; however in many of the reports, people have claimed that the glitch happened right after the GTS came up with no searches for any of the Pokémon but did not send out a Communication Error. After it stops blocking all access to other Pokémon, it is believed that is when the glitch is most likely to happen. Trying to withdraw the glitch Pokémon may result in a Communication Error but when the game lets a player withdraw the Pokémon, it returns to normal.

A similar glitch occurred where the Pokémon in the GTS is morphed into the wanted Pokémon (as shown in the photo). Instead of its name being the same as before, its name is now that of the wanted Pokémon, but still the same species as the Pokémon originally offered. There's also the possibility of the morphed Pokémon holding a Seal Bag. Most of the time, trying to trade for it will either cause a Communication Error or say that the Pokémon has been traded. In addition, sometimes these glitched Pokémon will be the only that appear when searching for Pokémon of a certain level.

GTS trade evolution oversight

There is a glitch in the GTS that allows Pokémon to evolve by being traded, but without actually trading them.

Players must first place a Pokémon that evolves by trading it (with the correct held item, like Metal Coat for Scyther or Electirizer for Electabuzz) onto the GTS. To prevent the deposited Pokémon from being traded away, players should request an impossible trade, such as a level 9 and under Mewtwo. The player must then search for a Pokémon on the GTS and trade for it. After this has been done, returning to the Pokémon that was placed on the GTS by the player and taking it back will cause it to evolve.

The risk of not being able to reacquire a Pokémon while trying to evolve it through trade evolution over the GTS is very great and this could have been a planned countermeasure. The requirement (a trade) must still be met in order for the Pokémon to evolve, but this system would prevent a player from potentially losing the Pokémon they wanted to evolve.

GTS vanishing glitch

There have also been instances of a "vanishing" glitch on the GTS. After uploading a Pokémon to the server and checking its summary without changing the Pokémon, the "SUMMARY" button is sometimes replaced with "DEPOSIT", suggesting that the Pokémon has been traded. Selecting "DEPOSIT" will cause a Communication Error, and the player will return to the front desk. Logging on to the server again will cause the Pokémon to reappear, with no noticeable changes.

Intro cutscene oversight

Main article: Game intro → Generation IV

In all the Generation IV core series games, the game overworld seen in the intro cutscenes has several differences from actual gameplay. This includes the design of some places and buildings. Similarly, several non-player characters are only found in the intro cutscenes and not in actual gameplay, while other non-player characters are absent or located elsewhere in the intro cutscenes.

For instance, the Moss Rock is absent from Eterna Forest in the intro cutscenes of Pokémon Platinum, and the Barrier Station (the house in the way to the Bell Tower) is missing the sign at the front and has a red color scheme in the intro cutscenes of Pokémon HeartGold and SoulSilver. See also more examples.

Pal Park name encoding glitch

In Western versions of the games, all characters before '0' (0xA1) on the Gen 3 character encoding table use the Japanese table rather than the international one. In other words, when a Pokémon is sent through Pal Park, all characters in its nickname and OT that occur before '0' on the international encoding table will be converted to their corresponding characters in the Japanese character encoding.

This appears to be the result of the developers using the Japanese encoding as a base and, for Western games, only changing the encodings for characters that are able to be input by the player (like changing fullwidth characters to halfwidth, or changing the quotation marks to match the language of the Pokémon). However the assumption that a Pokémon can only have inputtable characters in their Nickname and OT is false. Indeed, there are a few in-game trades in the Spanish games which have non-inputtable characters in either their OT or nickname, and a few preset Trainer names in the Spanish games also contain non-inputtable characters. All applicable cases are listed below.

Pomeg glitch

Main article: Pomeg glitch

Trade cloning

If a player is trading Pokémon and one of the handhelds is turned off at a certain time, the Pokémon that was traded to the game that was not turned off will appear in both player's parties. However, this glitch is very difficult to perform and quite commonly corrupts the save file.


Main article: Tweaking

Waterfall oversight

If, before going down on a Waterfall, left or right is pressed on the D pad just before down is also pressed, the player will descend the Waterfall facing left or right instead of down.

By Pokemon Glitches for Bulbapedia

DNS Mystery gift exploit

When a player sets Nintendo Wifi connection, entering a certain Primary DNS and Secondary DNS (variable by game) will enable them to receive most of the past Wifi mystery gift events. Also, the GTS can be accessed even though the service has been discontinued.

Pokémon Diamond and Pearl

Barry Underground glitch

If the player goes to the Underground while Barry is not present at the Fight Area on Saturday after saving on Friday night on the spot where he would appear, then comes up, the player will be on top of Barry. If the player saves the game whilst on top of Barry, as the game begins to save Barry's sprite will be brought forward and will stand on top of the player's.

By Pokemon Glitches for Bulbapedia

Barry rematch oversight

Although Barry appears in Fight Area only during Saturday and Sunday, if the player stays there without loading a different area or a building, Barry will remain in Fight Area and can be fought even if it's weekday.

Broken escalator oversight

This is one of two glitches in the games to be officially acknowledged by Nintendo,[1] with the other being the surf glitch. In early copies of the Japanese versions, after entering the Union Room on the second floor of the Pokémon League building, which shares the layout with the second floor of any regular Pokémon Center, the player will end up in a wall and not be able to return.

In the case the player has not saved the game while trapped, it is possible to work around the bug:[2]

  1. Reboot the game to load the previous save file.
  2. Go to the Super Contest Hall in Hearthome City.
  3. Speak to the leftmost attendant (there is no need to actually participate in a Super Contest).
  4. Save the game and restart.

Just like the surf glitch, in case the player saves the game after exploiting this bug, the effect could be corrected with a patch released by Nintendo (including versions for the Nintendo DS[3] and 3DS[4]), which allowed the player to resume the game in front of their house in Twinleaf Town. Alternatively, the players could mail their cartridges to Nintendo for repair. Both the patches and the repair service by mail were discontinued in February 2018.

Dress-up Hiker glitch

When talking to the Hiker at Jubilife TV who allows Pokémon to be dressed up, if a button on the D-pad is pressed so that the player is facing away from the Hiker just before the screen to select which Pokémon will be dressed up opens, the player will not walk on the set path; this can lead to walking through walls or the Hiker, or canceling the action altogether.

By Pokemon Glitches for Bulbapedia

Egg determination glitch

This glitch requires a Pokémon and an Egg in the same spot of adjacent boxes on the Pokémon Storage System. By having the cursor on the Pokémon in one box, pressing the L or R buttons to switch boxes as the display is rolling over to the next piece of data will allow the player to see the held item (always none), Nature, Ability, or type of the Pokémon inside an Egg.

By Wooggle Smith

Friendship underflow glitch

This glitch allows friendship to underflow to values close to 255. The player must do these:

  1. Start a wild encounter.
  2. Lose some HP on the Pokémon to increase friendship of, but don't make it faint.
  3. Use some EnergyPowder or an Energy Root in the battle.
  4. Run away from the battle.
By ChickasaurusGL

GTS cloning

This cloning method is reminiscent of the methods from the first two generations and involves the GTS.

If the Pokémon is deposited in the GTS and the connection is interrupted at the right time, the Pokémon in question would be in the player's party or Pokémon Storage System box and in the GTS, requiring the player only to withdraw the Pokémon from the GTS to obtain the clone.

Pal Park Retire glitch

Main article: Pal Park Retire glitch

Poké Mart text glitch

This occurs whenever the player uses Sweet Scent or Honey in a Poké Mart. Talking to the clerk and selecting the "BUY" menu will yield blank text for the names or descriptions for any of the items in stock. Accessing the "SELL" menu will correct the glitch.

By Pokemon Glitches for Bulbapedia

Ribbon check glitch

When the player's party is being checked for the total amount of unique Ribbons at the Ribbon Syndicate, Pokémon in party slots after an Egg will not have their ribbons counted.

By Meinanutshell

Silent Route 214 glitch

If the player goes onto Spring Path off Route 214, the music changes. If you open up your start menu and select any option that opens a secondary menu (Pokédex, Bag, Pokémon menu, etc), close the menu, return to Route 214, there will be no music. Sound effects such as collision sounds still occur and encountering a wild Pokémon will still play Battle! (Wild Pokémon) as expected. The same glitch can also be activated by changing the music using the bicycle.

By Pokemon Glitches for Bulbapedia

Sticky Hold/Suction Cups bug

Even if the player's first party Pokémon has Sticky Hold or Suction Cups, the probability of bites while fishing is not doubled as it was intended to be. This occurs because the equals sign in prob*=2 was missed during coding.[5] This was fixed in Platinum.

Surf glitch

Main article: Surf glitch

Pokémon Platinum

Black Belt speech error

BoEANSprite.png This glitch is in need of research.
Reason: Is this exclusive to the English versions?
You can discuss this on the talk page.

Due to consecutive spaces, Black Belt Eddie in Sinnoh's Victory Road will say "Done in" with every letter on an alternating line.

By 2009TNT

Full party framerate glitch

In Hearthome City and certain other graphics-heavy areas, framerate lag issues have been known to occur when running or riding the Bicycle. This is most likely to occur when the player has a full party of six Pokémon on them. The fewer Pokémon there are in the party, the less likely the lag issues are to occur.

GTS level display oversight

In early releases of the American version, when seeking Pokémon on the GTS, the game will not display the level range of the wanted Pokémon. This can result in confusion as offers are blocked so even if a player has the right Pokémon to offer but it is not at the right level, it will not able to be selected.

This glitch is not present the original Japanese versions or in other localized releases, indicating that it was a minor error made in the development of the American version. Nintendo offered a patch for the problem by sending in an affected game.

Member Card name error

If the player receives the Member Card from the man in the Poké Mart that delivers event Pokémon or event items, the name will be displayed as "Member's Card" as opposed to "Member Card".

Route 227 Underground glitch

Going to the Underground on Route 227 between Route 226 and the horizontal row with the first patch of tall grass, then coming back up will cause the player to be partly in the ground. Leaving this area causes the player to return to normal.

Pokémon Diamond, Pearl, and Platinum

Cheryl overworld glitch

At the entrance of the Eterna Forest, sometimes a non-player character will walk on top of Cheryl.

Disappearing PC Pokémon glitch

BoEANSprite.png This glitch is in need of research.
Reason: Need info on what causes it.
You can discuss this on the talk page.

Sometimes, Pokémon placed in the PC may disappear completely.[6][7]

Explorer Kit oversights

BoEANSprite.png This glitch is in need of research.
Reason: Other places?
You can discuss this on the talk page.

There are certain tiles where the player cannot use Explorer Kit despite being able to use in the rest of the area, with the message "Rowan's words echoed... <Player>! There's a time and place for everything! But not now." appearing instead.

By PkMkPresto

HM05 Defog error

HM05 error.

HM05 (Defog) appears as a Water-type HM rather than a Flying-type one.

Pal Park manipulation

Main article: Pal Park#Manipulation

This allows the player to migrate any number of Pokémon via Pal Park by overcoming the "six Pokémon per 24 hours" restriction.

Underground item duplication glitch

This glitch occurs in the Underground and makes it possible to "clone" a Goods item between two players. There is a chance of losing the item if both players do not follow directions properly.

To clone a goods item, one player must always give the item, and the other must always receive. This cloning glitch can be repeated indefinitely. To clone, one player must give the other an item. The player who gave the item turns the game off without saving, but the receiver should save the game. If the cloning was successful, both players should have the item. However, there is a chance that the cloning will not work and the item will be lost.

Another variation on this glitch can be used to "clone" traps. By having one player place a trap(s) and having the other player pick up the traps and saving, if the first player resets his game without saving both players will have the trap(s).

Pokémon HeartGold and SoulSilver

Additional Boulder error

In the Japanese versions, a boulder in the Slowpoke Well can be pushed off land into water. The boulder will still act as if it was on dry land. It was removed in the localizations.

Buena's Password glitch

BoEANSprite.png This glitch is in need of research.
Reason: This glitch is not fully confirmed, may affect other events that change daily and needs further testing.
You can discuss this on the talk page.

If the player saves the game as soon as they have stepped through a doorway or stairway and their first Pokémon has not appeared, then Buena will not give a new password the following day or any thereafter unless the player re-saves in a new location that allows the primary Pokémon to leave its Poké Ball.

Cianwood Gym walking Pokémon glitch

In Cianwood Gym, if the player stands in the center of the Gym behind the waterfall with a large Pokémon at the front of their party so that they have no walking Pokémon, then changes their lead Pokémon to a Pokémon that can walk inside the Gym, it will appear as a walking Pokémon on the next tier down. After moving a few steps away from the waterfall, the Pokémon is automatically jumped up onto the same tier as the player.

Floating walking Pokémon glitch

The player must have a Pokémon following them around and it must be poisoned. If the Pokémon walks off a ledge at the same time as it survives the poisoning, then the Pokémon will end up levitating in the air as if it is still jumping off of a ledge. The Pokémon will continue to levitate in the air until the player chooses to jump off another ledge, go into a building, get on the bicycle, or use either Surf or Fly. If the player switches walking Pokémon, the Pokémon will still be seen floating until the player exits the party menu.

By tayover18

GB Sounds muting glitch

If the player turns on the GB Sounds while surfing on Route 20, then turns the GB Sounds off while still surfing in the water of either Cinnabar Island or Route 20, the music will be muted until it is changed.

This glitch will not work if the player encounters a wild Pokémon while the GB Sounds is active.

By TeamFail95

Haircut brothers glitch

If the player tries to get another haircut on the same day from the Haircut brothers by changing the clock of the handheld, exiting the Goldenrod Tunnel, and entering it again will cause the other brother to be present but he will treat the player as if their Pokémon have already been given a haircut. Once the day properly changes, the other brother will be present but not give the player's Pokémon a haircut, acting like the player has already gotten one.

Indigo Plateau guard glitch

If the player attempts to enter the GS Cup in the Indigo Plateau Wireless Club and checks the list of special Pokémon, the guard blocking the entrance to Will's room will not move until the player reenters the building.

By ChickasaurusGL

Invisible grass oversight

Three tiles on Route 44 and four tiles in the Swamp area of the Safari Zone appear to be empty but when the player or the walking Pokémon is standing on the tiles, tall grass will appear underfoot. This grass appears between the top of the grass and the water on Route 44, and between the rightmost lake and the grass in the Safari Zone. Wild Pokémon may be encountered in this grass and Safari Zone objects may not be placed on it.

Overworld sprite corruption

Sometimes, when escaping the Ecruteak Gym is forced by Morty being absent, the overworld sprites will be corrupted once the player gets out of the Gym.

Poké Mart sign position glitch

Sometimes Poké Mart signs will appear as though they were built on the roots of trees, there is no known way to try getting this glitch to forcefully occur.

Pokéwalker data cloning

BoEANSprite.png This glitch is in need of research.
Reason: If the cloned Pokémon is traded out to another game, or leveled up in the Pokéwalker, does the game accept?
You can discuss this on the talk page.

When a Pokémon is successfully transferred to the Pokéwalker but the game is turned off before saving, the Pokémon would appear in both the Pokéwalker and the Pokémon Storage System box it was in before the transfer. However, attempting to bring the Pokémon in the Pokéwalker back into the game would cause it to be released into the wild, even if the original Pokémon data had already been deleted or moved, such as being traded or released. This is because the data of the Pokémon that was transferred was not saved onto the game, thus the game will not recognize the Pokémon that is on the Pokéwalker, therefore it releases it. The game only recognizes Pokémon caught from the Pokéwalker and the Pokémon's data that is stored in the game after the transfer. This is to prevent external or third-party devices from transferring Pokémon data onto the game.

Rival's non-Shiny starter Pokémon

The player is able to check if Chikorita, Cyndaquil, or Totodile are Shiny before choosing one of them as their starter Pokémon. However, if this starter that appeared as Shiny is obtained by the rival Silver instead, it will appear as a regular non-Shiny Pokémon for the remainder of the game. The rival's Pokémon teams are predefined in the game data, with no way to account for a possible Shiny starter Pokémon.

Walking Pokémon position glitch

If the menu is opened while the walking Pokémon jumps off a ledge and the player checks the status screen of any Pokémon in the party, the Pokémon will get a bit higher up, so viewing the stats of a Pokémon continuously will result in the Pokémon going off-screen.

By The King Burger

Pokémon Platinum, HeartGold, and SoulSilver

Giratina form change glitch

If Giratina has its held item changed to or from the Griseous Orb in the PC (i.e. using the "Move Pokémon" or "Move Items" option), it will change form, but its stats will not change to reflect its new form. It will retain these stats even after saving or being traded and uses these stats during link battles. Its stats will be changed to those of the correct form if it has its held item changed outside of the PC. Its stats are recalculated when leveled up, but since these changes are considered to be as a result of the level up, leveling up a Giratina affected by this glitch can cause negative stat growths.

By ChickasaurusGL

Graphics corruption

Standing in certain places of areas such as the Great Marsh, Ribbon Syndicate, or the Fight Area in Pokémon Platinum, or Route 31 in Pokémon HeartGold and SoulSilver may cause the foliage or walls to bend and merge into other graphics near them.

Wi-Fi Plaza glitch

If the player goes to the Wi-Fi Plaza, runs in the direction of another player, and reaches them about a second before they warp out, the two players will merge into each other until the second one warps out.

Pokémon Battle Revolution

Mystery Gift exploit

Although only one Mystery Gift is intended to be received by the player through its 300 seconds of transmission, there is nothing to stop a player with another handheld and a different game cartridge from receiving the same gift. For example, when purchasing a Salac Berry for 19,200 Poké Coupons and receiving it on one game cartridge, another player with a different handheld and game can quickly receive a copy of the same Salac Berry for free, provided that the 300-second period haven't expired.
