Go to the Pokémon Research Lab and take the elevator to the Director's office. Go to Mabel's desk.

Then go to Wild Zones 3, 5, and 9 to look for the anomalous alpha Pokémon. Catch or defeat them. They will all be level 70. After you catch or defeat all three, go back and talk to Mabel at the Pokémon Research Lab.

Next, go to the northern part Wild Zone 11 by going to Wild Zone 6 and going south, and using the northern entrance of Wild Zone 11. Approach the mission destination.

After you complete this mission and Main Mission 41: The One That Takes, try to go into Hotel Z, and you will start the mission Main Mission 42: To Keep the World in Balance.
