| Police Officer Location | |
|---|---|
![]() Rouge District Map |
![]() In front of the Lumiose Museum |
A police officer will be standing in front of the Lumiose Museum once this side mission is available. Upon approaching her, she will automatically call out to you and trigger the side mission.

The Lumiose Museum Heist involves Pokemon battles with three police officers, so make sure your party is battle-ready. It's recommended to use level 90-100 Pokemon on your team and to have a Poison- or Steel-type, a Dark-type, and a Fighting-type Pokemon to deal with the opponents you'll face.
Talk to Police Officer Licier in front of the museum once you're ready to start The Lumiose Museum Heist.
| Premiere's Pokemon |
|---|
Dachsbun Dachsbun Level 82 |
Drop down from the roof once you're ready to take on your first opponent. Premiere will be blocking the entrance to the museum. Upon approaching him, you will enter into a battle against his level 82 Dachsbun.
Dachsbun isn't particularly difficult to beat. Use Steel- or Poison-type moves to make quick work of Dachsbun, then proceed into the museum.
| Deuxieme's Pokemon |
|---|
Houndstone Houndstone Level 86 |
Upon entering the museum, the clerks at the counter will yell out in feigned shock. Once they're done with their scene, take the right entrance and go further into the museum. You will be stopped by Officer Deuxieme, your second opponent in this mission as his name clearly states.
Deuxieme has a level 86 Houndstone, which you can quickly beat using Dark- or Ghost-type moves. Using a Dark-type Pokemon such as Absol is recommended in order to resist its Ghost-type attacks.
| Troisieme's Pokemon | |
|---|---|
Mabosstiff Mabosstiff Level 91 |
Houndoom Houndoom Level 91 |
After beating Deuxieme, make your way to the second floor. Approach the ancient Sinnohan ritual outfit in the display case next to the Palkia statue. Investigate the outfit, then Officer Troisieme will arrive to try and stop you.
Unlike the other officers, Troisieme has two Pokemon in his party. However, they are both Dark-type Pokemon that are weak to Fighting-type moves. It's recommended to use a Fighting-type Pokemon such as Emboar or Hawlucha to deal with these Pokemon.
Upon defeating Troisieme, you will be transported back outside the museum and be rewarded for your enthusiastic participation in their training.

It's recommended to upgrade your Gold Canari Plush to level 3 if you haven't yet before doing this side mission.
