How can you recruit marshtomp?

To recruit a Marshtomp in Pokémon games like Pokémon Mystery Dungeon, you need to encounter it in a dungeon where it appears, such as the Water-type dungeons. Once you find a Marshtomp, you must defeat it in battle without knocking it out; using moves that don't reduce its HP to zero can help. After the battle, if you have a high enough recruitment rate, it may join your team. Increasing your team's overall level and using items like the Friend Bow can also improve your chances of recruitment.
