The Roaming Pokémon Roar glitch (not to be confused with the Roaming Pokémon IV glitch) is a relatively minor glitch that occurs with the Roaming Legendary Beasts in Pokémon FireRed and LeafGreen.
Usually when one of the Legendary Beasts flees, it should still be available but may have moved to a different route.
However, if one of the Legendary Beasts uses Roar it will cause the Pokémon to become unavailable.
