Glitch Trainer

Glitch Trainers are Trainers that can only be battled via the use of glitches.

Battling a glitch Trainer

Generation I

Glitch Trainers can be battled in one of two ways: the old man glitch (if the player's name contains certain special characters in the 3rd, 5th, or 7th slot) or the Ditto glitch (using Special stats ranging from 201-255RB or 201-253Y). Unlike other Trainers, glitch Trainers say nothing before or after the battle, and often use glitch Pokémon.

Old man glitch method

If the player encounters a glitch Trainer via the old man glitch, the team used by said trainer will be determined by the last team index number loaded, and the team will be always read from a nonexistent Trainer class #256 - so if a Gambler with team number 3 was fought last time and the player encounters a trainer via old man glitch, the game will load team #3 of trainer #256, regardless of the encountered Trainer class.

Below is a list of the first 10 teams of the trainers encountered via the old man glitch.

9 Rhyhorn Lv. 42 Arcanine Lv. 42 MissingNo. Lv. 42 Clefairy Lv. 42 Mewtwo Lv. 42 MissingNo. Lv. 42

Ditto glitch method

If the player encounters a glitch Trainer via the Ditto glitch, the Attack stage modifier of the Ditto used will determine which team will be used. This modifier is normally 7, causing the game to attempt to load the 'seventh' team; as most Trainers only have one set team, this almost always results in a glitchy team with several glitch Pokémon. If a move like Growl is used six times to lower the Ditto's Attack stage modifier to 1, then the loaded team will be valid.

Two particular Trainers, Prof. Oak and Blue, have three different possible teams based on the player's first partner Pokémon; therefore any Attack stage modifier from 1 to 3 will work. This is the easiest way to battle Prof. Oak with his original, dummied-out team.

ZZAZZ glitch

Main article: ZZAZZ glitch

If the player performs the Ditto glitch and uses a Special stat of either 251, 252, 254, or 255, the ZZAZZ glitch (a.k.a. The Exploding Bulbasaur Glitch) will be triggered. This glitch heavily corrupts the game's save file and memory, changing several in-game bytes to have a value of 153; most noticeably, parts of the player's name will be overwritten with multiples of the letter "Z" (index number 153), and most of the player's Pokémon will be changed to level 153 Bulbasaur (index number 153) with several copies of the move Explosion (index number 153).

Jacred

 
The player encounters Jacred

Jacred is a glitch Trainer class. Its name is derived from parts of the preset names that the player can choose for themselves and their rival, specifically "Jack" and "Red". 'Jacred' can be battled by performing the Ditto glitch with a Special stat of 200. Unlike other glitch Trainers, Jacred has no defined sprite and can instantly crash the game when the player's Pokémon uses a move or when the player accesses their party or uses an item.

There is also a ZZAZZ variant of Jacred, caused by using the Ditto glitch with a Special stat of 200 and Growl one or two times. Because this is a ZZAZZ variant, battles can be escaped using a Poké Ball, though the Bag will be corrupted. The screen is almost fully covered by PokéTrainer, but it is still possible to scroll down over Cancel, find a Poké Ball, and escape the battle. After escaping the battle, the player will be in a different Glitch City. The game will not be able to be saved, because when the party is opened, the game will lock. The city has no PC to indirectly save the game, nor a Pokémon Center where the save option can be restored by healing the player's party.

Prof. Oak

Professor Oak, who cannot normally be battled

Unused Trainer data for Prof. Oak (Japanese: オーキドせんせい Teacher Oak) exists in all Generation I games. He can be battled in different ways.

  • By performing the Ditto glitch using a Pokémon with a Special stat of 226 if the wild Ditto's Attack is lowered by 4, 5, or 6 stages (each number of stages will yield a different team; in order: Charizard, Venusaur, or Blastoise).
  • By performing the Old man glitch with a player's name containing the MN character in the third, fifth or seventh slots, Professor Oak can be battled as a glitch Trainer; however, he will not have a defined roster.
  • By performing a specific select button glitch in the Japanese Pokémon Red, Green, and Blue.

Chief

Chief

Chief is an unused Trainer class in the Generation I games. He has neither a defined sprite nor a programmed party. When battled, his sprite appears as that of a Scientist due to its Trainer class being directly after Chief in the game's data.

Chief can be battled using the Ditto glitch and a Pokémon with a Special stat of 227, or through the use of the old man glitch when the player's name contains a dash in the third, fifth, or seventh letter slot in English Pokémon Red and Blue.
