Jangmo-o has the pride of a warrior, although it remains humble about its capabilities. In its pursuit to become stronger, it never neglects its training.

Because Jangmo-o uses the scales on its head for both offense and defense, it never turns its back to its enemies. Many Trainers see this behavior and take it as proof that Jangmo-o is a valiant Pokémon.

Jangmo-o gather in harsh locales like canyons, where no other people or Pokémon are around, to live together as they train.
