Before you throw a ball

Catching Gastrodon

If you encounter a wild Gastrodon, an ordinary throw outside battle requires your first non-fainted party Pokémon to be at least its level.

  1. Party order matters: the game checks the first conscious Pokémon, not the highest level anywhere in your team.
  2. With no conscious party Pokémon, this outside-battle rule allows only targets up to level 15.
  3. A guaranteed-catch ball bypasses this ordinary level check. You can also battle a wild target and use a ball during your turn.

These rules describe wild encounters. Raids and scripted encounters may use their own capture flow. Read the catching guide and blocked-throw checklist · Checked .

Base catch-rate value: 75. This is a species value, not a percentage or a promise that a particular ball will work.
