Jangmo-o Evolution in Pokemon Sword
Jangmo-o is a Dragon-type Pokémon introduced in Generation VII. It evolves into Hakamo-o starting at level 35, which then evolves into Kommo-o starting at level 45. Jangmo-o is the first stage of the Kommo-o evolutionary line.
Evolution Requirements
In order to evolve Jangmo-o into Hakamo-o, it must reach level 35. Once it reaches this level, it will automatically evolve. To evolve Hakamo-o into Kommo-o, it must reach level 45. Again, once it reaches this level, it will automatically evolve.
Other Considerations
It should be noted that Jangmo-o can only be found in Pokemon Sword. If you are playing Pokemon Shield, you will not be able to find or evolve Jangmo-o. Additionally, if you are playing Pokemon Sword and have already evolved your Jangmo-o into Hakamo-o or Kommo-o, you will not be able to revert them back to their previous forms.
