This is a list of glitches that occur in the Generation II main series Pokémon games.

In Pokémon Gold and Silver

Present glitch

Main article: Present (move)#Generation II

In Gold and Silver, the move Present is glitched and the Level, Attack, and Defense variables of the damage formula are replaced. This causes the move to deal unusually large or small amounts of damage depending on the Pokémon. This glitch is not present in Pokémon Stadium 2 or Pokémon Crystal.

Trainer House glitch

Main article: Trainer House glitch

This glitch affects the Trainer in the Trainer House. It is caused by corrupted RAM for save data in Pokémon Gold and Silver. It is not present in Pokémon Crystal.

Bug-Catching Contest data copy glitch

Main article: Bug-Catching Contest data copy glitch

This glitch only appears in the Japanese versions of Gold and Silver, when a player flies out of the Bug-Catching Contest causing the creation of unstable Pokémon data. The glitch was fixed in Pokémon Crystal and in all international releases of Generation II games.

In Pokémon Crystal

Distorted cry

Reason: checking if it occurs in Gold and Silver.

If player plays the Entei's cry in Pokédex and then immediately switches to either Suicune or Raikou, their cry will be distorted.

Player sprite glitch

A glitch that can be found in Pokémon Crystal. This glitch causes an overworld sprite color switch between Ethan and Kris. It is caused by creating a save file as one gender of character, then overwriting it with another gender of character, but turning off while it is overwriting. It disappears after saving and resetting the game. Note that the old save file will be overwritten.

Exp. Share glitch

If a Pokémon with the same original Trainer as the player is sent into battle with an Exp. Share held, that Pokémon will gain half of the experience twice (with each half being rounded individually), meaning that it doesn't receive 100% of the experience due to it losing the rounded-down experience.

Experience gain glitch

Reason: image or video.

When Pokémon gains 5-digit amount of experience, the number will be glitched. This is possible only in the Trainer House. The lowest possible level is 82 for Pokémon with experience yield of 255, and the lowest experience yield with which this is possible with is 208.

Experience underflow glitch

Main article: Experience#Experience underflow glitch

In Generations I and II, level 1 Pokémon using the "medium-slow" growth algorithm will jump from level 1 to level 100 after gaining a low amount of experience points.

Leveling past 100

In Generation I and II, if a Pokémon is obtained at a level above 100, it can be leveled up with Rare Candies up to level 255. If a Rare Candy is fed to a level 255 Pokémon, its level will be reset to 0. If a Pokémon above level 100 levels up due to experience, its level will be reset to 100.

Love Ball glitch

The Love Ball only gains a catch rate of 8× on Pokémon of the same gender and species as the player's Pokémon, rather than the opposite gender. This was corrected in Pokémon HeartGold and SoulSilver.

Pokémon Storage System cloning

Sketch glitch

Main article: Sketch glitch

Thick Club glitch

If a Marowak with a maximum Attack stat (maximum IVs and Stat Exp in Attack) uses Swords Dance while holding a Thick Club, its Attack will overflow to 8. This glitch is not present in Pokémon Stadium 2.

Trade cloning

Main article: Cloning glitches#Trading method

Transform assumption glitch

In Generation I and II, any Pokémon that uses Transform is regarded as a Ditto in its new form; this means that if the player catches a Mew or a glitch Pokémon which has used the move Transform, or a Pokémon which has used Transform via Mirror Move, instead they will obtain a Ditto. Mew turning into Ditto was not an issue, because wild Mew could not have been be legitimately encountered. This system was later changed in Generation III, where wild Mew could be encountered.

Park Ball scrambled graphics glitch

If the player cheats to obtain a Park Ball in the Ball pocket of their Bag and uses it to capture a wild Pokémon, the game will fail to reload the graphics correctly, causing a temporary glitch in which part of both the Bag and battle screens are visible together until the Park Ball's graphics are cleared.

Glitches involving communication with the Generation I games

Johto guard glitch

Main article: Johto guard glitch

Shiny Ditto glitch

The Shiny Ditto glitch requires a game from Generation I and Generation II, but only has an effect on a Generation II game. In Generation I, if a Pokémon uses the move Transform while already transformed, after being caught it will retain the IVs of the Pokémon it transformed into. Due to Shininess being determined by IVs in Generations I and II, this allows the player to make a wild Ditto Shiny by having it use Transform while already Transformed; this can be accomplished by either having a Shiny Pokémon that knows Transform (Mew, certain glitch Pokémon, or a another Ditto), or by teaching a Shiny Pokémon Mimic, then having the wild Ditto use Mimic on the move Transform. While Shiny Pokémon do not exist in Generation I, due to being determined by IVs, this Ditto will be Shiny when traded to Generation II.

Trade evolution glitch

Generation I Pokémon that can evolve by trading can be taught glitch moves through this glitch. This can be achieved by trading a trade evolution Pokémon from a Generation I game to a Generation II, at a level where its evolved form will learn a move not in Generation I. Trading the Pokémon back to the Generation I game will cause the move to become a glitch move.

For example, trading a level 34 Graveler from Pokémon Red to Pokémon Gold will make the Graveler evolve into Golem. Since it is level 34, it will learn Rollout. If it is then traded back to Pokémon Red, it will still have the move, but the game won't recognize it properly since it is a Generation II move, so will become TM05.

In the side games

Pokémon Stadium 2

Infinite continues glitch

The infinite continues glitch is a glitch that can be performed in Pokémon Stadium 2 with any Stadium Cup. It does not work in the original Pokémon Stadium. If there is a previously suspended game and the player is playing the Stadium Cup, suspending the game after a loss causes a warning message to pop up, telling the player that there is already a suspended game. If "Continue without Suspending" is selected, a rematch with the opponent who just defeated the player will be triggered, but no continue will be used.
