Translations:EV training/6/en

Occasionally, a Pokémon may initiate a battle with you. If this happens with a Pokémon that does not yield the desired EVs, run. Running is dependent on the active Pokémon's Speed and the opponent's Speed, so if you have a higher level Pokémon in your party, switch to them rather than attempting run off the bat. If you can't get away, it may be best to allow your Pokémon-in-training to faint. Although this reduces happiness, it will prevent your Pokémon from gaining unwanted EVs. The easiest way to avoid random battles is by avoiding Pokémon you don't want to battle, especially those with high aggression such as Arbok.
