Now you're in the main part of The Under. Place the U-Disk into the UFO. This will make the platform go up. Not forward, up. You'll arrive inside the Pyrite Town windmill. You'll get a Time Flute. You can use it on Suicune. Go back down, up the stairs to the right, and up the lift to exit the Under. Leave Pyrite Town, go to the Outskirt Stand, get some more Ultra Balls. Go to the Shadow Pokémon Lab.
Shadow Pokémon Lab
Staying very close to the barriers, walk outside of the electric barriers to the right and up, and you will find 3 Revives at the back of the lab. Go back and insert the Maingate Key, and go to the bottom left to find 2 Full Heals. Go back and enter the lab's right door. One of the computers in this room has a Shutter Switch. Press it, and the left door will open. Exit the room and go through the left door. Save. Behind the wall where the PC is, hides 3 PP UPs. Head right, down the stairs, down, left, down the stairs, and get the Elixirs. Go upstairs, up, and you'll find a Researcher who will battle you.
Easy as pie. He'll flee, leaving the Card Key behind. Go back through the maze and outside, then through the right door. Insert the Card Key. Follow the path, and pick up the DNA Sample. Go left, and before you can take the elevator, a Cipher Peon will challenge you.
An exact clone of Odlow except his Pokémon are +1 levels. Beat him and on the table is the Down St. Key. Go back down the stairs and up the elevator, and then navigate right to the first elevator and walk down, through the door. Talk to the Researcher by the whiteboard.
Swablu and Zubat go down easy, Pupitar goes down pretty easy, and Forretress is so-so difficulty catching. Go down the elevator, take a left, and BAM! another Cipher Peon.
Throughout the next few rooms, two of them will have DNA Samples. If you head right from here, you'll get a Full Restore. Go up and take a right. You'll see a few elevators, and BAM! another Cipher Peon. You'll be going right, and BAM! another Cipher Peon.
Take the rightmost elevator, and check the DNA Analyzer. A three-Pokémon password is needed. Check the three DNA samples. Remember the three Pokémon. Head to the left elevator and head left, and a Researcher awaits.
Instead of Medicham, you'll have a second chance to get his Hitmontop if you missed it earlier. Hardest in the Lab so far, but still easy. Head forward to face the final Cipher Admin.
Raikou is among the toughest to catch. If you really need to, stock up on lots and lots of Ultra Balls before this battle. All of his Pokémon are extremely strong, so be on your best guard. Just to the right is a Data ROM. You must deliver this to Nett. Head back to The Under and go all the way to Nett's house. It's a list of Shadow Pokémon, but he has to find it because it was erased. You can now head to Realgam Tower, where several Shadow Pokémon and many, many Trainers lie.
