The Greatest Gift

Description: The mysteries of hyperspace have been unraveled, but Ansha's original goal still remains unfulfilled. More survey work may be needed to find that Legendary Pokémon!
Rayquaza, the Legendary Pokémon Ansha seeks, should be waiting on the other side of the emerald distortion that has appeared. Make a special donut and prepare to catch it!

With Lumiose City saved, Ansha asks that you continue to help her find the Rayquaza that she saw and Corbeau soon calls to get support. He mentions that while researching Darkrai, they found several odd readings of distortions in the city, the Ruby Distortion and Sapphire Distortion and that they're linked to Rayquaza. Lida, having come from Hoenn gives some history on Groudon and Kyogre and that they fought but Rayquaza came to calm them.

Corbeau mentinos that special donuts will have to be made and that you need to do more Hyperspace Surveys to find out. He also mentions that portals to Rogue Mega Evolution rematches have appeared which give big points and a lot of items.

Description: After the completion of the Survey, Corbeau calls and asks for you to meet at Nouveau Café as he has news. He explains that to get the donuts, you need to make the donut but then asks Grisham for some Hoennian Salt that he uses on his croissants. Grisham accuses him of espionage but Corbeau notes that it's due to Philippe being a cook .

He then gives the recipes.

Description: With Groudon & Kyogre captured, Corbeau calls upon you and you get further information on how to get Rayquaza. The idea is that you have to make a big wish to get the portal so you all go to the roof an have Ansha really think about Rayquaza and the history.

Soon after, the big portal appears above Hotel Z. They continue to discuss about Rayquaza and learn that it can Mega Evolve without the Mega Stone.

Philippe then comes in and mentions that you need more Hyperspace Survey Research to figure the recipt. This requires 100,000 Points.

After completion of the survey, Corbeau and Philippe arrive with the recipe to make. This requires 120 points in sweet, 40 points in spicy, 340 points in sour, 40 points in bitter and 390 points in fresh. Make ti to get the Delta Old Fashined Donut. Then take it to the portal to go to the Hyperspace Sky Ruins

Description: Like the Primal Pokémon, Rayquaza is faced in two phases. First is the standard Rayquaza which unleashes its Dragon Ascent and Hyper Voice at you, as well as Outrage to do close up damage. After it Mega Evolves, it will lose its weaknesses from Flying-type. It will continue to attack as before with Hyper Voice doing massive damage. Its charge attack creates numerous twisters around the area, pulling you around the stage while Meteor Beam is unleashed in succession, requiring you to dodge and avoid the damage. It will also use Dragon Ascent where it will bring up a massive twister and fly up, before shooting down. This can be prevented by attacking the twister.

Defeat it and you can catch it.

Description: Return to Hotel Z and you can show Rayquaza to Ansha. Ansha is happy but then starts to think about how she can't top the gift to her mama and doesn't want to leave as she would need to to give it to her. As Diantha is away filming, she decides to stick around and continue helping to explore Hyperspace Lumiose and asks for you to look after Rayquaza in the interim.
