Pokémon HeartGold Version - Kanto Pokémon Federation

On Route 8, there is a trio of bikers which call themselves the Kanto Pokémon Federation. One team of Koffing will use Sludge for a 30% chance of poisoning the target and Explosion that does massive damage but makes the user faint. Flareon will use Fire Spin to prevent the target from escaping for 2-5 turns.
