Trainer mutation glitch is a closed menu Select glitch in Pokémon Red, Green, and Pokémon Blue (Japanese).
It allows the player to change what groups of Trainers in a map say, how they turn, and what class they are. If the new 'class' is less than 200 (C8), then they will turn into Pokémon. The player can also change the Pokémon's levels.
Unfortunately the player can't manipulate the species/class of the first Trainer IDs 1-4 in a map unless they have a Pokémon with specific stat experiences (so no 'fresh' Pokémon) but they should be able to manipulate others.
Basic steps1) Press Select on the 20th item.
2) Exit and go into battle, then swap the 20th Pokémon with a Pokémon of your choice.
3) Without using a warp, go to a Trainer and they should have 'mutated'. Do note that a Trainer's text may freeze the game, and beware of Missingno. in Red/Green.
The game may freeze after the switch with no documented fix.
Every Trainer on a map has an ID. This glitch lets you change the Pokémon (or Trainer) and level that a certain Trainer ID is. The ID can be tracked with memory viewer by talking to a Trainer and viewing address CC55, CD4F, or CF0E. As maps have multiple Trainers (and IDs), you can mutate more than one Trainer.
When you switch the Pokémon, you're actually switching the 20th Pokémon with the first. This puts various Pokémon data into unrelated data, and one group causes the Trainer mutation effects.

ExampleLet's say you want specific Pokémon for Trainer IDs 02 through to 07 as such.
ID 02: Level 1 Mew ID 03: Level 254 Mewtwo ID 04: Level 5 Articuno ID 05: Level 5 Zapdos ID 06: Level 5 Moltres ID 07: Level 100 Porygon
This would require the following data from address D141:
15 01 83 FE 4A 05 4B 05 49 05 AA 64
And that is:
Defense experience is 21 modulo 256. Speed experience is exactly 387. Special experience is 65098. Defense DV is 5, Attack DV is 0. Speed DV is 11, Attack DV is 4. Move 1 PP is 5. Move 2 PP is 73. Move 3 PP is 5. Move 4 PP is 42 w/2(?) PP Ups used. Pokémon is level 100.
Those requirements are totally unviable for non-cheat play, so it's a proof of concept, but you can get cool results with random Pokémon.
