Part 11: Aether Paradise
Aether Paradise Docks
As soon as you've beaten Kahuna Nanu, a cutscene will take you back to Aether Paradise. Head left and north to battle the first trainer. Continue north through the crates; you'll run into three more trainers along the way. You can avoid them if you want, but we recommend defeating them for the expirience. Before getting on the elevator, head north for a Rare Candy. If you head south and to the left you'll find an X Sp. Atk and TM06 - Toxic. There's another trainer to the left of the elevator that you can battle if you'd like. Hop on the elevator when you're finished on this floor.
Gladion will take you to the first floor where you'll be greeted by the esteemed Branch Manager Faba who will want to battle. He has a Lv. 39 Hypno. You shouldn't have much trouble beating it, but it can put you to sleep and disable your moves, so watch out for that. After you win, Faba will agree to take you to the lower levels, but you should tell Gladion you aren't ready at first. You can head south a little and speak to the lady behind the counter to have your Pokemon healed. Now tell Gladion that you're ready.
When you get to the lower floor, Gladion will tell you to check out Secret Lab B and Hau will give you a Max Revive. Head right through the door. You'll run into three Aether Foundation employees that you'll need to defeat in battle. After defeating them continue all the way to the right and pick up the Zygarde Cell before entering Secret Lab B. Once inside, you and Hau will immediately face off in a double battle against a couple of employees. After you've taken them out, investigate the computer for the information you need about Cosmog and Ultra Beasts. Exit the room and then enter Secret Lab A. You can find a Full Restore here and read some interesting lore about Type: Null and Faba's blog. Head back left to the elevator and choose "1F".
You'll be confronted by some Aether Foundation employees and you'll have to take them on in another double battle with Hau. After you defeat them, Wicke will appear and heal your Pokemon after some more dialogue. Head north, following Gladion and Hau. After Hau roasts Faba a bit, you'll be pit against two more Foundation employees in a double battle with Gladion. Immediately after (your Pokemon will be healed first) you'll face off against Faba and another employee in another double battle, this time with Hau as your partner. Faba will have a Lv. 39 Slowbro, a Lv. 39 Bruxish, and a Lv. 40 Hypno. After winning both battles, head north through the open doors.
You'll find yourself in an outdoor area filled with Team Skull thugs. Head left and south to pick up a Full Heal. Head back right and to the south and you'll find a Zygarde Cell. Head back through the middle and start facing the Team Skull grunts. You'll have to beat two before getting to Gladion and Guzma. You'll then need to face off against Guzma once again. He has a Lv. 41 Golisopod, a Lv. 40 Masquerain, a Lv. 40 Ariados, and a Lv. 40 Pinsir. After defeating him, head left around the building to find a Zygarde Cell (daytime only). Enter the doors to the north when you're ready.
There's another Zygarde Cell under a shelf on the right side of this room. Enter through the center door. A cutscene will play where you learn that Lusamine is the mother of Lillie. Once the cutscene is finnished, follow Lusamine through the teleporter. Hau and Gladion will enter the room and you'll find out that Gladion is Lusamine's son and Lillie's brother. A long cutscene will continue and Ultra Beasts will be released into Alola. You'll have to face off against Lusamine. She has a Lv. 41 Clefable, a Lv. 41 Milotic, a Lv. 41 Mismagius, a Lv. 41 Lilligant, and a Lv. 41 Bewear. After you've beaten her, she'll disappear into the worm hole with Guzma. Another cutscene will play and your Pokémon will be healed.
