Player two having apparently sent out a Spearow that just fainted after the Fire Spin glitch was caused.

The Fire Spin glitch is a Link Battle de-sync glitch in Pokémon Red, Blue and Yellow.

It is a glitch which activates an oversight in the two-player capabilities of the game's battling system. On one user's side, one of his or her Pokémon has not fainted, but on the other user's side the same Pokémon has fainted, meaning that communication errors will persist until the battle ends.

Requirements

1. Two players.
2. Access to the Cable Club.
3. A working link cable.
4. Player one requires a Pokémon knowing Mirror Move.
5. Player two requires a Pokémon knowing Fire Spin.
6. On player one's side; a Pokémon which could be defeated in one move by Fire Spin.
7. Ideally player one should have the Pokémon knowing Mirror Move as the first party member.
8. Ideally player two should have the Pokémon knowing Fire Spin as the first party member.

Method

1. Both players should enter the Colosseum via the Pokémon Cable Club and battle.
2. In battle, player one should send out the Pokémon knowing Mirror Move and player two should send out the Pokémon knowing Fire Spin.
3. If the Pokémon knowing Mirror Move is faster, have the opponent use Fire Spin and wait until the Pokémon escapes it. If the Pokémon knowing Mirror Move is slower, have the opponent use Fire Spin and hope it misses, then on the same turn Mirror Move it.
4. Player two should switch his/her Pokémon to one that can be defeated in one hit by Fire Spin, and have it hit. If it doesn't hit, you'll have to try the glitch again to see its other effects.
5. If performed correctly, on player two's screen Mirror Move will fail and his/her Pokémon would not faint. On player one's screen however, the game considers that player two's Pokémon has fainted if Fire Spin hit.
6. Communication errors will persist, including the opposing players sending out a Charizard 'M or Q, the fainted Pokémon or another glitchy Pokémon.
